Fig. 1.

A fundus color photo shows a localized white/yellow oval depression in the inferotemporal segment of the optic disc and diffuse macular swelling. An SD-OCT scan through the fovea (a) shows cystic accumulation of fluid in the inner retinal layers adjacent to the disc, a schisis-like accumulation of fluid in the outer nuclear layer, and an underlying retinal detachment. This scan cannot detect any definite communication between the retinal separation and the optic nerve, but an SD-OCT scan taken at the inferior margin of the disc (b) shows a colobomatous pit of the nerve head.
