PURPOSE:
To
report a case of corneal and lenticular
pigmentation after prolonged
clozapine therapy. CASE
SUMMARY:
A 56-year-old
male visited our
hospital with a progressive decline in
vision that affected both
eyes. He had a
history of
schizophrenia. He was being treated with 200 mg
clozapine and 1 mg
lorazepam daily, and had been treated with
clozapine for 5 years. At the first visit, his best-corrected-
visual acuity was 20/32 in both
eyes.
Slit lamp examination of the
corneas showed bright, fine, grayish-brown deposits on the
endothelium, and on
dilation, bilateral central stellate opacity of the anterior portion of the lens
capsule was revealed.
CONCLUSIONS:
Clozapine may induce corneal and lenticular
pigmentation and thus may
lead to a decline in
vision.
Patients on long-term
clozapine therapy should be considered for regular ophthalmic
review.
