Unfortunately, there really is a significant number of diseases of the organ of vision, leading to irreversible blindness.
This happens when retinal cells located in its central part (macula) are destroyed (or deprived of nutrition), the processes of these cells that conduct a signal to the visual centers of the brain (they form the optic nerve) or the visual centers themselves .
According to the WHO, approximately 80% of all cases of blindness can be prevented or treated.
The most common conditions causing irreversible blindness include glaucoma, diabetic retinopathy and age-related macular degeneration.
Only timely diagnosis in the early stages allows you to preserve vision in these diseases, but, unfortunately, they are often asymptomatic, until the process goes so far that the decrease in vision becomes irreversible.
This happens especially often if the disease affects only one eye, because good vision in the second eye can mask the problem.
Regular preventive examinations by an ophthalmologist, approximately once a year, allow timely identification of pathology and, if necessary, start treatment at an early stage of the disease.
Good afternoon! Unfortunately, such pathologies exist, for example, glaucoma, some retinal pathologies, optic nerve atrophy, etc.
We recommend that you regularly visit an ophthalmologist for prophylaxis, and in case of visual impairment or discomfort in the eye, you should urgently contact full-time consultation with an ophthalmologist.
Yes, unfortunately there are. This is a fairly broad group of diseases that can lead to blindness and surgery cannot restore or maintain visual acuity. Most often this applies to diseases associated with damage to the optic nerve, diseases of the central retinal zone, as well as a large group of hereditary eye diseases.
