The retina of the eye is the inner shell lining it from the inside. It contains nerve cells (rods and cones), which are responsible for the perception of the light flux entering the eye and the transmission of the image to the brain.
The retina has the most dense attachment in the region of the optic nerve disk and on the periphery of the dentate line.
For a number of reasons (myopia, genetic predisposition, trophic disturbance, trauma, etc.), thinning may occur on the periphery of the retina, dystrophic processes may develop, and retinal breaks may form. These pathological processes can lead to retinal detachment and loss of vision.
When “dangerous zones” are identified, laser photocoagulation of the retina is performed, which delimits zones of dystrophy and breaks, thereby reducing the risk of possible detachment.
