Argon laser peripheral iridoplasty for topiramate-induced bilateral acute angle closure.

PURPOSE: To report a case of a topiramate-induced bilateral acute angle closure that was treated successfully by argon laser peripheral iridoplasty (ALPI).

METHODS

A 59-year-old healthy woman taking oral topiramate developed bilateral acute angle closure. B-scan ultrasonography, ultrasound biomicroscopy, and slit-lamp adapted ocular coherence tomography were performed.

RESULTS

The patient had shallow anterior chambers and total angle closure for 360 degrees OU. Ocular imaging showed circumferential ciliochoroidal effusions with anterior displacement of the iris-lens diaphragm. ALPI relieved the angle closure.

CONCLUSIONS

ALPI should be considered as initial therapy for topiramate-induced acute angle closure.
