Estimated Enrollment: 37
Study Start Date: August 2011
Estimated Study Completion Date: October 2013

Detailed Description:

Intravitreal Bevacizumab has been used by retinal specialist in treatment many retinal diseases. Although it not approved by FDA for treatment. In many In vitro studies, its showed saftey in the eyes especially for corneal endothelium cells, that important cells to keep cornea clear. This study use Confoscan-Corneal confocal microsope to evaluate corneal endothelium before and after intravitreal Bevacizumab injection in routine retinal disease at 6 month follow up.
