Cystoid macular edema associated with limbal melanoma.

Early cystoid macular edema causing some loss of central vision in an eye with an 8-year history of limbal melanoma was studied histopathologically. A typical combination of slight chronic uveitis, vitreoretinal traction, parafoveal separation of posterior vitreous and inner-limiting membrane, swelling with distinct cystoid changes in Henle's fiber layer, and foldlike detachment of foveal cones is described and discussed.
