METHODS OF VISION RECOVERY WITH SHORTSIGHTEDNESS, LONG SIGHT, ASTIGMATISMS, AMBLYOPIAS, CONGENITAL AND HEREDITARY RETINA AND OPTIC NERVE DISEASES

One of the most urgent problems of infantile ophthalmology is the development of efficient methods for amblyopia treatment - the most frequently occurring vision pathology among children and taking a high percent among adults.

The most frequent reason for amblyopia is the concomitant strabismus occurring among 1,5-4% of children (E.S.Avetisov, 1997). Amblyopia which appears as a result of shortsightedness, long sight, astigmatism and congenital and acquired cataract is substantially spread among the pathologies of organ of vision and often is the reason of poor sight. Poor sight as a result of congenital refraction anomalies makes 45% (E.S.Libman, E.K.Miroshnikova and others).

New apparatus methods of treatment based on the latest achievements of vision physiology, optics and physics which have been recently suggested can not be applied to younger children as they demand a certain intellectual level neither can they be applied to middle or upper schoolchildren or even more so adults due to their ineffectiveness. In some cases these methods require conditions of specialized kindergartens and health centers because of their labour-intensiveness and duration. The surgical methods, which are used for curing strabismus and amblyopia are not always ensure cosmetic and especially functional recovery of the patients.

That is why the method of video and computer vision correction based on reflex selection and bioelectric activity of the cerebral cortex optic zones which allows to remove functional and cortical mechanisms of amblyopia formation is considered rather perspective.

Problems of the patients suffering from shortsightedness are evident. Myopia is the most frequent vision defect. Myopia progression can lead to irreversible changes in the eye and considerable loss of vision. Complicated shortsightedness is one of the main reasons for disablements due to eye diseases. Significance of the problem is still increasing because of the fact that complicated myopia develops among the people of the most efficient age category. In this respect the suggested method of video and computer vision correction is rather effective in increasing the vision functions at shortsightedness and quite perspective in stabilizing its progress. Its essence consists in working out EEG (electroencephalography) specific parameters of the occipital areas whose dynamics at the vision load reflects the status of the eye adjustment function.

Quite obvious are the problems of children and adults with congenital and acquired retina and optic nerve diseases who are in need of disablement, specialized boarding schools, professional and living rehabilitation. Drastic vision reduction of every 4th child in this group is conditioned not by organic but functional disorders and development of amblyopia, which emerged due to untimely its treatment and ametropy correction. Potential possibilities of vision functions recovery on application of video and computer vision correction method consist in the degree of functional changes during the aforesaid pathological states.

Vision correction with help of video and computer auto-training method restores the possibility to see normally without operations using the resources of the brain for recovery and intensification of vision acuity.

A new method of treating long sight, shortsightedness, amblyopia and congenital and hereditary eye diseases among children and adults is suggested using AMBOIOKORR-01 equipment (RU 2080845 A 61 F 9.006 1996, Avdeyeva A.A.).

In the proposed method we take the patient`s EEG with the help of three electrodes. Bioelectric activity educing from occipital and frontal areas is given to the envelope-forming block shown on the screen in the shape of a diagram reflecting the integral EEG with the scanning speed of one minute whereupon it is fed to the threshold device comparing the EEG envelope amplitude with the threshold value by means of voltage comparator. The signal is supplied from the threshold device onto the screen and turns it on or off depending on the EEG parameter changes. Thus close circuit of biological feedback is formed. It includes the patient whose occipital area EEG is registered, the computer making EEG analysis and the video system reproducing material image whose brightness changes according to the status of occipital area bioelectric activity.

Treatment of eye diseases is based on the principle of self-regulation under the conditions of biological feedback. At the same time the controllable unit is the eye function and the controlling one - the cortical bioelectrical processes. The core of the method comes to the patient`s bioelectric activity selection, in the course of training those EEG dynamic states are produced and fixed which determine the best visual functions (material image has the clearest perception), i.e. a new communication system supporting such visual acuity as is nearer to the optimal. High clinic effect of this method is based on the brain capability for invoking visual rehabilitation processes when there is a high motivation at the sub-consciousness level. Deterioration of perception dims out the screen and improvement of perception turns it on. The effect of treatment in many respects depends on positive motivation inducing the patient to see and distinguish as much as possible that is why cartoons or feature films are used as material images. Due to the patient`s eagerness to see as much as possible the states of bioelectric activity that determine the best vision are fixed and which makes the patient able to reproduce the image. Those states of the brain worsening the material image perception are eliminated.

According to the existent concept during the visual load the EEG changes of the occipital area reflect the status of cortical support sections, generally the eye adjustment function. In the course of training not only the corrigible vision acuity (VA) is increased but also the incorrigible VA in the absence of static refraction dynamics, which testifies that this method influences the adjustment apparatus.

According to the proposed method the main role in the mechanism of adjustment relaxation is played by the central sections of the vegetative sympathetic and parasympathetic nervous systems performing the adjustment regulation which leads to a higher degree of its relaxation unlike the methods of direct mechanic effect on the muscle by way Dashevsky and Avetisov-Matz training. This method of treatment based on biological feed-back in rather short terms (10-15-20 sessions) allows to achieve relaxation of cylinary muscle, eliminate the adjustment spasm which is the starting moment for shortsightedness development, as a result the vision acuity is increased and dynamic refraction is decreased to a significant extent. It allows reduce the intensity of correctional optic lens and has in itself a positive effect in the course of stabilizing myopia progress.

In a number of cases during the training we manage to suppress a- rhythm and reduce its amplitude which is accompanied by the concentration of the patient`s attention, increase of the visual fixation, adjustment and convergence effort and which is an efficient mechanism of vision recovery at shortsightedness, long sigh astigmatism. The target of the treatment is the improvement of vision acuity at such vision defects, refusal of permanent glasses wearing and reduction of correcting lens intensity.

The suggested methods can be first of all applied for treatment of different kinds of amblyopia (vision incorrigible by glassed or contact lenses). In the course of treatment the functional cortical mechanisms of its formation are removed which is indicated in the change of parameters of brain occipital area bioelectric activity produced in the course of training. The principle of operation is based on restoration and fixation the violated by some reason afferent and efferent nervous connections between optic receptor of each eye and correspondent brain visual center as well as cortical centers of both halves of the visual analyzer.

This method of treatment based on self-regulation under the conditions of biological feedback and strict close circuit: retina - visual cortex - video and computer system, makes it possible to restore the violated connections between the eye and cortical sections of the visual analyzer and to achieve the information perception from the amblyopic eye, to overcome inhibition arising in the brain cortex. In process of training the brain as if "learns" to perceive the pulses from the poor sighted eye on the condition of the healthy eye occlusion. That is why this method can be used for treatment of amblyopia caused as a result of strabismus. Aiming to see image on the screen the patient will be aiming to perceive images by the central sections of retina since the image can be held in video system for a long time only in this manner. Thus the incorrect fixation shifts from periphery to the center, which allows treatment o patients with non-central and even peripheral fixation. The essential principle of the described mechanism is the principle of reflex selection of brain condition that governs the eye functions.

In cases of amblyopia emerging due to congenital or acquired shortsightedness, astigmatism or long sight and in cases if congenital or acquired cataract the visual functions grow underdeveloped due to image defocusing on retina or nervous receptor occlusion by cataract. Treatment of such kinds of amblyopia on the condition of mandatory correction of refraction and aphakia anomalies allows to a great extent to increase and improve visual functions because as the basis of the patient`s desire to see as much as possible such brain condition is reflexively fixed as determines a better vision, which is sequent of the image defocusing removal and elimination of retina nervous receptors underdevelopment.

In this method it is for the first time offered to restore the residual visual functions and rehabilitation of the patients with organic diseases of retina and optic nerve. Earlier the children of this category practically had no rehabilitation treatment since the main method was that of light treatment having the property to cause additional degeneration of retina epithelium. The method offered is absolutely safe because unlike the light treatment it causes no additional degeneration of retina neuroepithelium but only removes functional refraction, adjustment and amblyopic "cortical" factors deteriorating as it is the poor sight of the patients suffering from retina and optic nerve diseases.

In significant percentage of cases the congenital retina and optic nerve diseases are accompanied by nystagmus, secondary strabismus caused as a result of central area affection by refraction changes, amblyopias which were developing owing to optic correction disuse because of its intolerance or "having no perspective". In some cases it is hard to define to which extent the vision degradation is determined by nervous and receptor apparatus pathology and to which it is determined by refraction, adjustment and amblyopic factors. The extent of functional disturbance in many respects determines the potential possibilities and perspectives of visual functions recovery applying this method.

It is important to mention that for the first time we offer a method combining absolutely safe pleoptic treatment and strong adjustment effect which is very important in such cases as nystagmus and congenital shortsightedness that often goes with organic changes and tends to progress if adjustment is weakened. As a result the degree of relative amblyopia may as well be increased in some cases due to refraction increase.

In the proposed methods following the original training aimed at improvement of material vision perception the compensatory resources of retina nervous and receptor apparatus nearest to the center are at maximum enabled in cases when its phaveolar or macular area is affected by dystrophy processes, central chorioretinitis, hemorrhages, etc.

It should be marked that in organic especially in unilateral processes there are factors functioning on the basis of mechanism of unilateral anisotropic amblyopia such as disuse of information from the eye having a pathological process or disuse of information from the eye with a more expressed and highly advanced stage of disease.

In the course of rehabilitation of patients with organic diseases of optic nerve retina the secondary functional mechanisms of cortical origin are removed and it leads to the improvement of visual functions.

In accordance with the aforesaid it is necessary to define INDICATIONS FOR APPLICATION of the video and computer vision correction method.

1. Refraction disturbances

1. Long sight and long-sighted astigmatism of weak, medium and high degree.

2. Shortsightedness, myopic astigmatism of weak, medium and high degree.

3. Adjustment spasm against the background of:
a) myopia and myopic astigmatism of weak, medium and high degree;
b) emmetropic refraction (normal refraction);
c) long sight and long-sighted astigmatism of weak degree.

4. Mixed astigmatism.

2. Amblyopia (reduction of vision accompanied by the absence of total correction with prescription of lenses optimally correcting refraction disturbance and unconditioned by the presence of retina or optic nerve organic diseases)

5. Refraction amblyopia (congenital or acquired double-sided shortsightedness, astigmatism, long vision accompanied by the absence of total correction in glasses.

6. Anisometropic amblyopia (monocular congenital or acquired shortsightedness, astigmatism, congenital long sight accompanied by the absence of total correction in optimal lenses).

7. Amblyopia of obscure origin on the background of monocular and double sided aphakia (degradation of vision caused by removal of congenital or acquired cataract and accompanied by the absence of total correction after prescription of corresponding lenses).

8. Strabismus, strabismic amblyopia (degradation of vision caused by strabismus and accompanied by the absence of total correction in optimal lenses).

3. Organic affection of organ of vision

9. Congenital and hereditary maculodystrophy.

10. Peripheral tapetoretinal dystrophy.

11. Degeneration vitreoretinalis (Wagner, Goldman-Favr etc.) at the absence of retinoschizis or with retina detachment after their surgical treatment.

12. Partial atrophy of the optic nerve of congenital and hereditary genesis as well as post-traumatic, toxic, inflammatory, glaucomatous, ischemic, compression genesis and etc. (nystagmus, opticochiasmatic arachnoiditis, disseminated sclerosis).

13. Conditions after suffered central chorioretinitis of various aetiology.

14. Post-traumatic detachment of retina after surgical treatment.

15. Central hemorrhages of retina.

16. Cataract not removed for certain contra-indications on the condition of their incomplete occlusion of the optical port.

17. Seams and corneal leukoma on condition they not fully block the optic port.

4. Presbyopia (age-specific vision degradation leading to the necessity to wear glasses for reading and writing).

CONTRA-INDICATIONS

1. Inflammatory diseases of retina and optic nerve in acute stage.

2. Detachment of retina of any genesis without surgical treatment.

3. Partial atrophy of optic nerve as a result of decompensated process (glaucoma, opticochiasmatic arachnoiditis, tumor etc.) if there is no necessity for surgical or medicament treatment of the primary disease.

4. Treatment of refraction myiopic disturbances with the purpose of improvement of incorrigible vision acuity at the absence of amblyopia and which are accompanied by concealed divergent strabismus at the fixed motion with 5-7% run, alternating divergent strabismus, as the operation in "relaxation" mode relaxes adjustment and therefore convergence, which can increase deviation or promote to transition of concealed strabismus to alternating.

It should be noted that the abovementioned contra-indications are relative and these groups of patients may and should be accepted for rehabilitation treatment after the completion of inflammatory process, the elimination of optic nerve compression by the tumor and liquidation of the increased intraocular pressure by surgery or medications. The offered method as it is does not use any forms of physical influence on the organ of vision but realizes reflexive ways of visual function correction.

SIDE-EFFECTS

Quick-passing headaches in the beginning of the treatment course especially among the patients with initially low visual functions at serious disturbances of vision.

Average improvement of vision acuity as a result of treatment at shortsightedness
Weak degree - 0,86 - 0,65
Medium degree - 0,64 - 0,48
High degree - 0,55-0,37,
Which is three times better than after adjustment training in replacement lenses according to Avetisov-Matz when the vision acuity increase made 0,2.

Adjustment relaxation by the method of video and computer correction of vision allowed to decrease the correcting lens intensity till 1,5-1,0D at myopia of weak degree, till 1,5D at myopia of medium degree and till 1,0-1,5D at myopia of high degree.

Since the method of video and computer vision correction significantly improves the eye muscle adjustment function which inferiority according to the common opinion is the starting moment in emerging and progression of shortsightedness we can affirm that this method affects the important pathogenic unit for shortsightedness development and may be the strongest factor of its stabilizing. Research has established that the process of shortsightedness stabilizing was registered among 80-85% of patients, which is 1,1-1,7 times better than application of other methods of treatment (adjustment treatment according to Avetisov-Matz, Danishevsky and others) and what is especially important it is not less effective than sclera-strenghening operations.

An important advantage of this method is the possibility to influence the progress and development of shortsightedness among children and teenagers. In spite of the generally-known fact that children and teenagers are not subject to laser plastic or keratoplastic operations due to process progression, is as well generally-known that the success of any plastic operation at shortsightedness is much greater at its smaller degrees which is achievable using video and computer auto-training in the period of its progression. It is quite unnecessary to ask a question about what the patient should better do - a laser plastic operation that in fact does not eliminate the original reason of the disease origin and development but only surgically changes anteroposterior eye dimension thus fixing a focus on retina or go through video and computer vision correction that solves the same problems by means of adaptation mechanism of the organism, perfection of muscle operation of the eye, self-regulation under conditions of biological feedback and improvement of perception and processing of the visual information in cerebral cortex.

In a number of cases video and computer auto-training is used in combination with laser and keraroplastic operations in particular in such cases when the patient can not be accepted for surgical treatment due to persistent progression or in remote postoperative periods when vision degradation recommences owing to primarily weakened adjustment function and retina asthenia.

RESULTS OF AMBLYOPIA TREATMENT

In cases of refraction and anisometropic amblyopia (i.e. amblyopia emerged as a result of monocular or double-sided shortsightedness, long sight, astigmatism) the diagnosis was cancelled in 100% of cases after treatment.

In cases of dysbinocular amblyopia (i.e. amblyopia that emerged as a result of strabismus) this diagnosis was cancelled among 65% of children.

In cases of amblyopia of obscure origin (i.e. amblyopia emerged after removal of congenital or acquired cataract) amblyopia diagnosis was cancelled in 59% of cases.

After treatment of all kinds of this pathology (300 people) only 10% preserved amblyopia but its degree substantially decreased.

The changes of amblyopia degree in the course of treatment is given in the diagram.

Results of amblyopia treatment and changes of its degree

Picture 1. Results of amblyopia treatment and changes of its degree

Not a single patient remained having high and very high amblyopia degree. Out of 10% (correction level 0,01-0,1) 2/3 of patients had a weak amblyopia degree after treatment (correction in glasses above 0,4) and 1/3 had a medium degree (correction level 0,2-0,3).

Improvement of vision acuity without correction in cases of different kinds of amblyopia is given in the following diagram

Improvement of incorrigible vision acuity

Picture 2. Improvement of incorrigible vision acuity

Vision acuity increase without glasses made 0,6 in cases of long sight and 0,5 in cases of shortsightedness.

Vision acuity increase with correction made on the average 0,6 in all kinds of amblyopia.

It should be marked that the efficiency of amblyopia treatment by this method does not depend on the age of the patient despite the existing concept, which is graphically shown in the following picture.

Percentage ratio of patients belonging to different age-groups who obtained 100% corrigible vision acuity

Picture 3. Percentage ratio of patients belonging to different age-groups who obtained 100% corrigible vision acuity

Examples.

1. Patient Sasha T., 4 years old. Diagnosis: long vision of high degree of the right eye, convergent monolateral strabismus, amblyopia of very high degree of the right eye, peripheral fixation.


Before treatment: Vision acuity of the right eye 0,01 with the lens +6,5 - 0,02
Vision acuity of the left eye 0,8 with lens +1,5 - 1,0.
Strabismus angle according to Girshberg 30°.


After treatment: Vision acuity of the right eye 0,7 with lens +6,5 - 0,9
Vision acuity of the left eye 1,0 with lens +1,5 - 1,0.
Strabismus angle according to Girshberg 8-9°.
Fixation - central -> paraphaveolar.

As a result of two treatment courses the vision acuity improvement till 0,7 without glasses and till 0,9 in glasses was registered as well as reduction of strabismus angle to 20° and considerable fixation displacement from periphery to the center.

2. Lena B., 11 years old. Diagnosis: condition after removal of cataract of the right eye, aphakia of the right eye, amblyopia of obscure origin of very high degree of the right eye.


Before treatment: Vision acuity of the right eye 0,01 with lens +11 - 0,01
Vision acuity of the left eye 1,0.


After treatment: Vision acuity of the right eye 0,1 with lens +11 - 0,8
Vision acuity of the left eye 1,0.

As a result of treatment vision acuity improvement with aphakia correction made 8 lines. The girl now fits for the operation in implanting an artificial crystalline lens.

3. Patient Sasha D., 9 years old. Diagnosis: congenital myopia of the left eye of high degree, complicated, chorioretial form. Amblyopia of the left eye of high degree.


Before treatment: Vision acuity of the right eye 1,0
Vision acuity of the left eye 0,02 with lens -11 - 0,1.


After treatment: Vision acuity of the right eye 1,0
Vision acuity of the left eye 0,4 with lens -11 - 0,9-1,0.

As a result of treatment the non-corrected vision acuity improved till 0,4 and vision acuity with correction increased till 0,8.

Estimating the results of treating patients suffering from congenital and acquired retina and optic nerve diseases it is advisable to divide them into two groups.

1. Patients with affected retina central area due to maculodystrophy, post effects of central chorioretinitis, hemorrhages, detachments etc.

2. Patients with preserved retina central area. Here belong children with optic nerve partial atrophy, peripheral and equatorial vitreoretinal degenerations.

The initial vision acuity in the group with central retina apparatus affection made on the average 0,06 and with correction in glasses - 0,1.

After treatment the average vision acuity without glasses equaled to 0,36 " 0,4 and with correction in glasses - 0,6.

Vision acuity increase without glasses amounted to 0,3 and vision acuity increase in glasses - to 0,5.

In the second group of patients with preserved retina central apparatus the average vision acuity before treatment made up 0,09 and 0,2 with correction. After treatment vision acuity without correction made up 0,4 and -0,8 with correction. Improvement of vision acuity with correction was on the average 0,6 which testifies to the role of the secondary functional refraction and amblyopic factors in reduction of vision among these patients

Examples.

1. Patient Tania Y., 11 years old. Diagnosis: optic nerve partial atrophy of the left eye. After effects of craniocerebral trauma and infectious encephalitis.


Before treatment: Vision acuity 0,1 in glasses +3,0 - 0,1
After treatment: Vision acuity 0,7 with lens +3,0 - 0,9.
Vision acuity improvement without glasses till 0,6 and with glasses till 0,8 was marked.

2. Patient Lena Zh., 5 years old. Diagnosis: Riger`s syndrome, sub-compensated glaukoma. Glaucomatous excavation of the optic nerve disc. Partial glaucomatous atrophy of visual nerves of both eyes. Ectopy of the left pupil of the eye. Long-sighted astigmatism of medium degree of both eyes.

After treatment: Vision acuity 0,8 and with lens +2,5 cyl +2,0 ax 90 - 0,9.
Vision acuity improvement till 0,7 with glasses and without correction was marked.

3. Vova Ch., 4 years old. Diagnosis: central maculodystrophy of both eyes. Horizontal nystagmus. Secondary divergent strabismus. Mixed astygmatism of both eyes.

After treatment: Vision acuity of both eyes 0,4 with lens 0,5.
Vision acuity improvement till 0,36 and with glasses - 0,4 was registered.

4. Patient Aleksey P., 18 years old. Diagnosis: central tuberculous chorioretinitis of the right eye. Remission stage is located in phaveolar and partially in macular area (retina central area).


Before treatment: Vision acuity 0,1, incorrigible.
After treatment: Vision acuity of the right eye 0,8.

Vision acuity improvement till 0,7 was marked.

Advantages of treating amblyopia by the method of video and computer vision correction defined on the basis of comparative analysis and traditional methods are obvious.

The efficiency of the proposed methods for treating amblyopia and of those methods that existed earlier (pleoptic-orthoptic-diploptic method, stimulation by dynamic contrast-frequency stimulus, electric acupuncture method, treatment by structured and light stimulus etc.) is given in the shape of a diagram.

1 - video and computer vision correction 2 - treatment of amblyopia simultaneously by structured and light stimulators; 3 - method of treatment by subcutaneous electric stimulation; 4 - combined pleoptic-orthoptic-diploptic method of treatment; 5 - contrast-frequency stimulation with alternating angle parameters; 6 - method of electric acupuncture; 7 - treatment by surface multi-acupunctural stimulation; 8 - stimulation by dynamic contrast-frequency stimulus

Picture 4. Comparative analysis of the video and computer vision correction method and traditional methods

Summarizing the results and drawing a comparative analysis of treating amblyopia and congenital and hereditary diseases of retina and optic nerve we may assert that the suggested method of treatment in comparison with the traditional ones has the following advantages.

1. Average VA improvement with correction in course of treatment by other methods made 0,2 and while applying the video and computer vision correction method - 0,6, which is 3 times higher.

2. This method of treatment allows to restore visual functions among children with peripheral fixation at strabismic amblyopia and alternating fixation. Treating these categories of patients by other methods is considered ineffective. It means patients with any kind of fixation at strabismus are subject to treatment by the proposed method.

3. Vision acuity improvement among the patients with peripheral fixation in course of treatment by light methods made on the average 0,04-0,03 and in course of treatment by the method of video and computer correction - 0,3-0,4 which is 10 times higher.

4. The efficiency of amblyopia treatment by the proposed method is 96%, which is on the average 1,5-2 times higher than during vision recovery by the complex pleoptic-orthoptic-diploptic method, electric acupuncture method, surface multi-acupuncture stimulation, light methods, contrast-frequency stimulation and others.

5. The rate of vision recovery in course of complex traditional treatment is 6-10 months while in course of treatment by the proposed method is on the average 1 month, which is 8 times quicker.

6. The method is conservative, absolutely safe and practically can not do any harm to the patient.

7. The method combines a pronounced pleoptic character and the possibility of strong influence on adjustment, which allows to restore VA not only with optic correction but partially without it as well.

8. Treatment by this method does not require any conditions of a specialized health center of taking a patient to the hospital. It is efficient in conditions of a regular surgery. The method has an entertainment character; it does not involve painful or unpleasant feelings and that is why children enjoy visiting vision correction sessions.

Making a comparative analysis of treatment of congenital and acquired retina and optic nerve diseases by the method of video and computer vision correction and by the previously existing methods such as medical therapy (taufon, ENKAD), subcutaneous and direct electric stimulation, laser stimulation, revascularization operations and etc.) the following advantages should be marked:

1. Visual functions improvement is registered among all patients regardless of heaviness of disease and degree of the initial degradation of visual functions.

2. Improvement is registered in 100% of cases, i.e. among all patients regardless of heaviness of disease and degree of the initial vision degradation, which is 1,9 times higher than on the average while applying other methods.

3. Visual functions stabilization is also registered among all patients with organic pathology, i.e. in 100% of cases, which is 1,85times higher than on the average while using other methods. At the same time the visual acuity achieved as a result of treatment could reduce in course of time but it never fell below the initial value and in such diseases as optic nerve atrophy or retina abiotrophy it is in itself a positive result.

4. Average improvement of visual functions in the group of patients with retina and optic nerve diseases amounted to 0,55, which is 2,75 times higher than while using other methods of treatment.

5. The method is absolutely safe and unlike the light treatment it does not cause additional degeneration of retina neuroepithelium.

6. This method can be applied in rehabilitation of the patients with organic vision affection irrespective of remoteness of disease or the age.
