Degenerative Retinoschisis

What is degenerative retinoschisis?

The retina lines the inside of the eye like wallpaper. It is has multiple layers that are normally stuck together. Degenerative retinoschisis is an age-related disorder where these layers split.

How is degenerative retinoschisis diagnosed?

Virtually all patients with degenerative retinoschisis are completely asymptomatic. The retinal splitting, which may be in one or both eyes, is detected by your eye doctor during a dilated retinal examination as a smooth solid retinal elevation.

How is degenerative retinoschisis treated?

Almost all patients with degenerative retinoschisis need no treatment since the retinal splitting does not usually progress. Rarely patients can develop holes within the split tissue that can mimic or cause a retinal detachment. Patients are usually examined every 6 to 12 months. New flashes, floaters or painless side vision loss are symptoms of a retinal detachment, and need to be examined immediately.
