Abstract IRIS MELANOMAS may be characterized clinically by acquired unilateral hyperchromia and glaucoma.1 The same findings, however, may be produced by non-neoplastic processes.2,3 The present report concerns such a pseudomelanoma in which neovascular glaucoma secondary to central retinal vein occlusion was the initiating factor. Report of a Case History. —A 65-year-old white woman noted sudden loss of vision in her left eye during the month prior to enucleation. The right eye had poor vision for an undetermined period of time. Clinical Examination. —There was a vitreous hemorrhage in the left eye with a visual acuity of light perception and projection. The right eye had no light perception. The right intraocular tension was 38 mm Hg (applanation) and it was within normal limits in the left eye. The right cornea had a large epithelial bulla in the inferior temporal area with a thin pigmented retrocorneal membrane behind it. This membrane References 1.
