Abstract
BACKGROUND: Deposits in the cornea and lens are a known complication of long-term chlorpromazine therapy. METHOD: A 59-year-old woman had previously taken chlorpromazine for 20 years with doses up to 1,200 mg/day, with a mean dose of 400 mg/day. She presented with gradual onset of blurred vision in her left eye. Slit-lamp biomicroscopy revealed multiple fine creamy-white deposits on her corneal endothelium and anterior crystalline lens capsule bilaterally. RESULTS: In vivo confocal microscopy of the cornea identified irregular hyper-reflective deposits on the posterior surface of the endothelium. The deposits varied from 1 microm to 70 microm in diameter and had well-defined edges. Endothelial morphology was otherwise normal bilaterally. CONCLUSIONS: This is the first report of in vivo confocal imaging of deposits resulting from long-term chlorpromazine use. Microstructural analysis of the corneal endothelium reveals that there were no abnormalities in cellular morphology resulting from these deposits.
