Subretinal fibrous membrane following argon laser photocoagulation of presumed histoplasmic maculopathy.

Following an initial improvement after argon laser slit-lamp photocoagulation of histoplasmic choroiditis, progressive visual loss occurred. Histopathological examination showed a dense fibrous membrane between Bruch's membrane and the sensory retina. There was no recurrence of hemorrhage or subretinal fluid. This case report provides an explanation for visual loss in the absence of recurrent inflammation or vascular leakage.
