What are the causes of retinal degeneration?
Physiologically, the water content of the body changes with age. The eye is also affected by this, because less and less water is stored in the vitreous body, which is located between the lens and the retina. It gradually begins to shrink. The tractions (pulling forces) and adhesions (sticking) that occur eventually cause the retina to tear in the affected areas.
Sometimes holes form, which become larger as the retinal degeneration progresses. In the worst case, the retina detaches completely. A longer eyeball, knitted in its shape, is particularly susceptible to this eye disease. That is why nearsighted patients are affected to a greater extent.
Again, it also depends on the way of life over years or decades, whether the disease comes to an outbreak. See: What are the causes of macular degeneration?
What are the symptoms of retinal degeneration?
There are a number of symptoms that indicate incipient retinal degeneration. Typical are “flashes” that are perceived even when the eye is closed. Other signs make themselves felt in the form of the so-called “sooty rain”.
The latter are dense, black appearing spots in the visual field. If you notice such symptoms, a visit to an ophthalmologist is strongly advised.
