Corneal Endothelial Cell Changes In Silicon Filled Eye

Corneal Endothelial Cell Changes In Silicon Filled Eye

The aim of this study is to evaluate corneal endothelial cell changes after pars plana vitrectomy in Rhegmatogenous Retinal detachment , compare the results using different silicon oil viscositites , and assess whether these changes are reversible after silicone removal or not .
