Purpose:
To report an unusual case of orange pigment pseudohypopyon overlying a choroidal nevus.
Methods:
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.
Results:
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.
Conclusion:
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.
