CZ9795A3 - Process of corrective non-ivasive improvement of vision by an eye affected with partial degeneration of retina - Google Patents

Abstract

Optical signals observed are fed to the degenerate retina of the eye environment, by observing the image the observed environment on the screen of the front device, for example, an optoelectrooptical transducer with auxiliary circuits, a CCD chip, and a screen whose output the optical signals are adjusted by controlling the electrical signals to achieve a proper brightness screen in relation to the overall state of degeneracy retina, and, if necessary, observe the pre-corrective eye means of altered accommodative ability of the eye.

Description

TECHNICAL FIELD

The invention relates to a method of correcting non-invasive action on degenerated retina by suitably light-amplified signals mediating the image of the observed environment, obtained by electronic means to the extent and content of known solutions of classes G and H of the International Patent Classification.

BACKGROUND OF THE INVENTION _________ ______

The causes of insufficient vision due to impairment of the optical system of the eye can be roughly divided into two groups for the purpose of explaining the creative idea of the present invention. ......... ....

In the first group it is a violation of accommodation and the clarity of the eye lens falls in the vitreous humor, in the second group it is a violation of the functioning of the retina with its light-colored elements.

Elimination of the defects mentioned in the first group has been successfully performed by corrective non-invasive means, glasses or contact lenses for a considerable time.

The removal of the defects mentioned in the second group by corrective non-invasive means is not known and the actual treatment of degenerated retina is performed by invasive means of ophthalmic surgery and / or by the use of medicamentous treatment by means of ophthalmology and internal medicine.

Corrective non-invasive means, glasses, can be enhanced in their effects by using magnifying magnifiers, or after reading the text of prismatic sliding rulers, with the eventual illumination of the near and not very distant surroundings. These measures will also improve the vision of the partially degenerated retina somewhat, but it does not help continuous vision in the range of 0.33 m to infinity, i.e. when observing distant surroundings. t

SUMMARY OF THE INVENTION

The invention remains solely in the field of physical non-invasive devices, not a therapeutic measure which must be left to the development of scientific knowledge of living matter and the practice resulting therefrom in ophthalmology or internal medicine. Thus, it is only a correction device similar to the first group of removing the causes of insufficient vision of the eye by the glasses. , v

For the purpose of explaining the invention, only the most important data on the most important human meaning - sight and its organ, eye - are given. The eye is formed by an eye ball embedded in the cranial orbit with limited mobility, the outer shape of the eye being given and maintained by the whitening, continuing in front of the eye ball through the transparent cornea. Eye ball wall. i consists of three base layers. The aforementioned whiteal with cornea and then inwardly the eyeball, the calyx with the choroid and the most important thin membrane, the retina with its light-colored elements and the yellow spot as the center of vision and blind spot, the point of optic nerve exit from the eyeball.

The front visible part of the sclera is covered by a translucent conjunctiva, flowing smoothly from below the inside of the eyelids and ending at the sclera / cornea interface. Behind the cornea is an iris with a circular pupil.

In the inner space of the eye ball is placed behind the pupil of the iris a resilient lens, essentially an interconnected lens, the internal focus of which lies in the healthy eye on the surface of the retina.

In the healthy eye, the inner space of the eye ball is further filled with a clear gelatinous substance of the vitreous humor - whose task is to maintain the shape of the eye ball and to press the retina to its lower layers, the choroid and whites.

The retina has a yellow spot on its inner surface in the center of vision, where the light-colored elements are concentrated most, and the optic nerve target, a blind spot in which a number of nerve fibers converge from nerve cells across the retina to form the optic emerging from the eye ball. out. The blind spot contains no light-colored elements, one does not realize its existence, and the continuity of vision is not disturbed. ...

The eye and its parts, like any human organ, are subject during life to the effects of either external influences such as injury, infection, neoplasms, effects of light of inappropriate intensity and wavelength, changes, treatable by invasive ophthalmic and / or internal medicine; or due to natural aging of individual parts of the eye, lens opacities, vitreous humor, turbidity or change in its volume, resp. its spinning, leading to mechanical stress on the retina at the junction of the vitreous with it, resulting in its tearing and detachment from its lower layers. These disorders, caused by aging and long-term operation of the eye, can be adjusted by physical means - glasses of short-sighted, farsighted or most-sighted eyes, or treatable by invasive methods regarding the lens, vitreous and retina.

Retinal degenerative changes treatable by essentially non-invasive measures are not yet known, but the course of the disease, if detected early, can be slowed down by appropriate medications and, in advanced cases, by degeneration of the retina also surgically or by laser radiation resulting in disease stabilization. partial decrease in vision brightness. The decision to take a laser stabilization procedure is a difficult decision for the patient and • a considerable psychological burden.

All in all, the quality of vision when degeneration slows down, fast or loose, is getting worse, and even stabilized degeneration causes considerable mental and physical discomfort.

Correction of eye defects, nearsightedness, hyperopia and hyperopia through non-invasive physical measures, pre-alignment of the eye with altered vision, due to the difficulty of accommodating the lens, optical device, lens of the appropriate type and focal length - glasses measures.

Complete regeneration of the degenerated retina and its macula is virtually impossible to date, but its degeneration is retarded by drug treatment or stabilized at the cost of the aforementioned conditions.

The inability to substantially cure degenerated retina by invasive and medication methods of ophthalmology and internal medicine, resulting in the patient's subjective feeling of constant darkening of the observed environment and color bias, invokes the idea of resorting to a non-invasive method and use similar to correcting insufficient accommodation ophthalmic lenses also by non-invasive means utilizing state of the art, physics and electronics to deliver a degenerated retina of the optical signals of the observed environment appropriately amplified, thereby providing a non-invasive light-intensively adjustable correction means that would amplify the electrical signals of the observed environment on the optoelectrooptical screen. A properly amplified transducer, that is to say, mediated by the illumination of the observed environment, would compensate for the reduced sensitivity and sensitivity of the degenerate retina, thus eliminating the patient's feeling of constant life in the dark and thereby also mentally relieving it.

*

The inventive idea constituting the inventive task was solved by providing degenerated retina of the eye with the optical signals of the observed environment indirectly, by observing the image of the observed environment on the eye screen of the upstream device, eg optoelectrooptical transducer with auxiliary circuits. are adjusted by controlling the electrical signals of the optoelectro-optic transducer to achieve a suitable screen brightness in relation to the overall functional state of the degenerated retina and further observing the altered eye accommodating ability of the eye by upstream correction means.
