The retina is a layer of light-sensitive tissue at the back of the eye that consists of light-sensitive cells (rods and cones) and nerve cells that receive and organize visual information. The retina provides vision by sending the visual information it receives to the brain through the optic nerve, which is the optic nerve. In healthy eyes, the retinal layer is in contact with the pigment layer just below it and the vascular layer it nourishes. Retinal detachment is the separation of retinal tissue from the adjacent retinal pigment epithelial layer. It is most common between the ages of 40 and 70. For this reason, the other eyes of the patients who develop retinal detachment in one eye should be examined in detail. Therefore, its treatment is urgent. It gives symptoms such as a large number of "black spot clusters like soot raining" that appear suddenly, accompanied by "light flashes", followed by the inability to see a part of the visual field or the veiling of a region and its progressive progression.
3 types according to the way it occurs
-
Ripped retinal detachment: It is the most common type. Whether the jelly-like liquid (vitreus) filling the cavity of the eye liquefies due to age or trauma, the structure of the collagen changes and begins to shrink. During this shrinkage, the retina is separated from the surface. During the separation of the vitreous from the retinal surface, a hole or tear may occur in those areas when separating from the optic nerve, vascular circles, macula region and the regions at the tip of the eye, to which it is attached, and the patient may feel strong flashes of light during this time. If this tear is noticed and fluid enters through the hole, the retina may detach and ruptured retinal detachment may develop. occurs. These membranes can pull the retina and separate it from its place.
-
Serous retinal detachment: An inflammatory disorder that occurs behind the retina and causes fluid accumulation, cancers that will form behind the retina, or blood vessels� It can be seen in vascular diseases that cause abnormal enlargement of the anterior retina to leak proteins that accumulate in the posterior part of the retina. Without a tear or hole in the retina, fluid accumulates under the retina and the retina separates.
