AN 18-YEAR-OLD Hispanic man was seen intermittently during a 7-year period with chronic iridocyclitis and iris crystals of the left eye associated with heterochromia. Recently, he had decreased visual acuity in the left eye. His visual acuity was 20/20 OD and counting fingers OS. The left eye showed medium-sized, stellate, keratic precipitates throughout the cornea, moderate anterior chamber reaction, and a posterior subcapsular cataract. Large, iridescent, iris crystals (Figure 1), moderate hypochromia, and iris stromal atrophy were seen. The right eye was unaffected. Laboratory investigation on 2 occasions showed no abnormalities in serum protein electrophoresis. A diagnosis of Fuch heterochromic cyclitis was made. The left eye peripheral iridectomy specimen was submitted for histopathologic examination following cataract surgery.
