Retinoschisis with Outer Layer Retinal Break
This 34-year-old woman presented with no visual complaints. Her visual acuity was 20/20 in both eyes. Upon examination her maculas were normal but her peripheral retinas were abnormal. In the right eye she had retinoschisis (white arrows) with an outer layer retinal break superotemporally (yellow arrow). In her left eye she also had retinoschisis but did not have any breaks. In degenerative retinoschisis, the retina splits into inner and outer layers. This usually occurs so far out in the periphery that patients with this condition do not notice any symptoms. Retinal detachments from retinoschisis are unusual occurring in less than 0.5% of cases. Although accumulation of fluid between the layers is not uncommon, this condition generally does not cause vision loss.
