Below you will find more information about Retinoschisis from Medigest. If you believe that you are suffering from any of the symptoms of Retinoschisis it is important that you obtain an accurate diagnosis from a medical professional to ensure that you obtain the correct medication or treatment for your condition. There are medical conditions that carry similar symptoms associated with Retinoschisis and therefore the information provided by Medigest is offered as a guideline only and should never be used in preference to seeking professional medical advice.

Retinoschisis refers to the abnormal splitting of the neurosensory layers of the retina. The splitting usually occurs in the outer plexiform layer. In rare cases, retinoschisis results in vision loss. However, in most cases, it remains asymptomatic.
Electroretinogram (or ERG) is an important diagnostic test to determine retinoschisis. This process entails stimulating the eye with light after either light or dark adaptation while the patient wears contact lenses embedded with an electrode. The eye's reaction to the stimuli is then documented and evaluated. The ERG test measures photoreceptor activity as well as the overall response of the retina's external layer.
To date, retinoschisis has no available medical or surgical cure. Treatment is mostly directed towards symptom relief. While glasses may help improve the afflicted patient's vision, they do not repair the damage to the nerve tissue. If detected early, retinal detachment in retinoschisis patients can be treated surgically, but surgery itself does not correct the actual splitting of the retina.
Symptoms and Signs
RS affects two aspects of the affected individual's vision. First, retinoschisis may impair the central vision. Secondly, the peripheral vision may be damaged as a result of the splitting of the inner layer of nerve cells from the outer layer of cells. In severe cases, retinoschisis can lead to retinal detachments, often as a consequence of a defect in the anchoring of the retina's outer layer to the wall of the eyes.
Retinoschisis may be degenerative (reticular or typical), hereditary (familial foveal retinoschisis or X linked juvenile retinoschisis), tractional, or exudative (in which case the disease is only secondary to optic disc pit).Discuss Retinoschisis in our forums
