Abstract

Objective To study the effect on corneal endothelium after Nd ∶YAG laser peripheral iridotomy.Methods Twenty two cases(26 eyes)were treated by Nd ∶YAG laser peripheral iridotomy.The corneal endothelium of 26 eyes was examined before operation and 1 week,1 month,3 months and 6 months after operation with non contact specular microscope.Results The corneal endothelial cell density and percentage of hexagonal endothelium decreased significantly before and after treatment(P0.05),whereas the mean cell area and coefficient of variation of endothelium increased in the meanwhile.Conclusion Nd ∶YAG laser peripheral iridotomy can cause damage of corneal endothelial cells to some extent.
