Abstract

Splitting of the nerve fiber layer at the macular region is known as macular schisis. It is typically seen in X-linked juvenile retinoschisis and hence more common in males and is almost always bilateral (Eriksson et al. 2004). Characteristic features on fundus examination include radial plication of the internal limiting membrane and microcystoid-like spaces. This is hence often wrongly misdiagnosed as cystoid macular edema. Peripheral retinoschisis, pigmentary degeneration, and beaten metal appearance may be other associated findings (Apushkin et al. 2005).
