Retinoschisis with Retindal Detachment

These are wide angle fundus photos from an 80 year old male with chronic inferior retinoschisis and a secondary retinal detachment. Retinoschisis occurs when cystic areas are filled with fluid form within the inner retinal layers. Retinoschisis is generally benign, however, it can lead to a retinal detachment if there are both inner and outer layer holes present in the walls of the cyst. This occurs in 0.5% of cases. The chronic retinal detachment is indicated by the blue arrows. In this case, pigmented scar tissue (yellow arrows) developed at the margin of the chronic retinal detachment and prevented the fluid from progressing further. The patient has been stable with this appearance for twenty years.
