Notable Cases

Ocular pigmentation associated with clozapine

MJA 2009; 190 (4): 210-211

A 55-year-old woman who was treated with long-term, high-dose clozapine for schizophrenia presented with bilateral decreased visual acuity. She had pigmentary changes affecting the cornea and the retina, as well as stellate cataract. Chlorpromazine use is known to produce similar changes, but this is the first report to our knowledge of pigmentation associated with clozapine use. (MJA 2009; 190: 210-211)
