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.
