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 sometimes the peripheral retina.
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.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]

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. [10]
A retinal tuft is a gliotic degeneration of the retina composed of focal adhesions in the extracellular matrix joining the retina and the posterior hyaloid of the eye. [4] [5] Retinal tufts are a common lesion of the retina and under 1% of these tufts are thought to lead to retinal detachment.
2. Excessive Stress. Stress is a natural, normal part of the human experience, and your body knows how to handle it. When you’re under stress, your body releases stress hormones that activate ...
Alterations in receptor distribution can be the result of epiretinal membrane, neuroretina detachment and/or re-attachment, or retinoschisis. Macropsia caused by surgical re-attachment of macula-off rhegmatogenous retinal detachment is not symmetrical around the fovea, resulting in differences size changes in the horizontal and vertical ...
