A colobomatous optic disc anomaly and associated retinal detachement.

A case is presented of a two-year-old white female with an optic nerve anomaly and an associated retinal detachment. A unilateral colobomatous disc was noted to be surrounded by a chorioretinal pigmentary alteration in the form of an annulus. A clear zone with absence pigmentation ringed the more central gray-black area. The retinal vessels were noted to come directly out of the deeply colobomatous disc area and to run between the cystic convolutions of the adiacent retinal tissue. A surrounding area of retinal detachment extended for a distance of three disc diameters from the disc. This case is one of a few yet reported in the literature.
