Retinoschisis is an eye disease characterized by the abnormal splitting of the retina's neurosensory layers, usually in the outer plexiform layer. Retinoschisis can be divided into degenerative forms which are very common and almost exclusively involve the peripheral retina and hereditary forms which are rare and involve the central retina and ...
Retinoschisin also known as X-linked juvenile retinoschisis protein is a lectin [5] [6] that in humans is encoded by the RS1 gene. [7]It is a soluble, cell-surface protein that plays an important role in the maintenance of the retina where it is expressed and secreted by retinal bipolar cells and photoreceptors, [8] [9] as well as in the pineal gland.

The causes of macular edema are numerous and different causes may be inter-related. It is commonly associated with diabetes.Chronic or uncontrolled diabetes type 2 can affect peripheral blood vessels including those of the retina which may leak fluid, blood and occasionally fats into the retina causing it to swell.
The most popular theory behind this association is a separation of the layers of the retina, known as retinoschisis, due to fluid (the vitreous humour) entering the optic pit and traveling between the inner and outer layers of the retina. The outer layer may then subsequently detach. Evidence of retinoschisis has been demonstrated using OCT.
J E MacVicar et al. describes 2 brothers, product of a consanguineous marriage, who exhibited signs of "idiopathic retinoschisis and early hemeralopia, Goldmann-Favre type" alongside other symptoms such as an angiomatosis-like tumor present in one brother and a lamellar macular hole in the other brother. They also described two unaffected ...

Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness.The retina is the eye's "sensing" tissue. Retinitis may be caused by a number of different infectious agents.
