Degenerative retinoschisis threatening central vision

A 65-year-old white male patient presented with asymptomatic bilateral degenerative retinoschises. The striking feature of this case was the posterior extent of the retinoschises. In each eye the posterior margin of the retinoschisis lay within 15 degrees of the macula, thereby potentially endangering central vision. The posterior border of a retinoschisis often lies posterior to the equator. However, it seldom reaches the major retinal vascular arcades. It is even rarer for a retinoschisis to approach the macula.
