Retinal disinsertion

It is attached tightly only in 2 places: in the optic nerve and in the periphery of the retina (dentate line). For the rest of the time, loosely connected with the pigment layer of the choroid, which creates conditions for exfoliation. The most common cause is a rupture on the retina, its degeneration, progressive myopia, pathological processes in the vitreous body (destruction, dilution, wrinkling), hemophthalmia, concussion, penetrating injury. It can provoke physical stress, lifting of gravity, shaking of an organism, a blow to the head.
The patient complains of narrowing the field of vision, the "curtain" in front of the eye, a decrease in vision, a "spark" in the eye.
On the fundus there is a grayish bladder, the retinal vessels are convoluted, they fold over the folds, the optic nerve disk can be bordered or hard to see. Usually you can localize the gap. To clarify the diagnosis, ultrasound one- or two-dimensional scanning is possible.
Most often surgical. Under the place of the rupture through the sclera, a seal is put from the silicone sponge or the eye is pulled along the equator with a silicone tape. At the edge of the rupture coagulation is produced by cold, diathermy. With flat detachments, it is possible to delimit the rupture with a laser, after which the retina, as a rule, adjoins.
The prognosis for early forms of detachment is favorable in 50-90% of cases. But detachment of the retina remains a formidable condition with high disability in the end.
