A man in his 30s presented for assessment of long-standing iris lesions in both eyes. He was unaware of any recent changes in the size or number of these lesions. His visual acuity measured 20/25 (6/7.5) OU, and his intraocular pressures were 14 mm Hg OU. The patient had noticed progressive visual obscuration in his left eye. He was not taking any ocular medications, and his only systemic medication was an oral β-blocker. He was otherwise healthy, and his family history was noncontributory.
