Topical latanoprost causes posterior movement of lens in a patient with exfoliation syndrome and subluxated lens: a case report

INTRODUCTION To report the effect of topical latanoprost on the position of a subluxated lens. CASE PRESENTATION After 0.005% latanoprost was administered topically to a patient with ocular hypertension due to a pseudoexfoliation syndrome and a subluxated lens, the position of the lens was examined by slit-lamp biomicroscopy, and the ciliary body thickness by ultrasound biomicroscopy. The lens had moved posteriorly, and the thickness of the ciliary body had decreased after the latanoprost. CONCLUSION We suggest that the decrease in the thickness of the ciliary body resulted in an increase in the tension of the zonule of Zinn fibers, thus pulling the subluxated lens posteriorly.
