Pseudohypopyon of orange pigment overlying a stable choroidal nevus.

Abstract

To report an unusual case of orange pigment pseudohypopyon overlying a choroidal nevus. Observational case report. A 45-year-old man presented with best-corrected visual acuity of 20/25 and metamorphopsia in the right eye secondary to localized subfoveal fluid. The detachment displayed a peculiar appearance of layered orange pigment, like a pseudohypopyon in its inferior aspect. Closer inspection revealed an underlying choroidal nevus and no choroidal neovascular membrane. After 31 months of follow-up without treatment, the size of the nevus and visual acuity remained stable and metamorphopsia continued to resolve as the orange pigment and the subretinal fluid disappeared completely. An otherwise stable choroidal nevus can display overlying clumps of orange pigment and rarely massive accumulation of orange pigment in the form of a pseudohypopyon. Orange pigment pseudohypopyon can spontaneously resolve with preserved visual acuity.
