The Effect of Dexamethasone Implant on Retinal Nerve Fiber and Optic Disc Morphology in Patients With Diabetic Maculopathy

This study evaluates the effect of dexamethasone implant which is an intraocular corticosteroid on the optic nerve fibers. Retinal nerve fiber thicknesses and optic nerve head pitting rates were measured before and 6 months after the injection.

Detailed Description

Diabetic macular edema is the most frequent ocular complication of diabetes resulting in irreversible loss of vision if untreated. Dexamethasone implant implant is used to treat macular edema due to diabetes. It stay in the vitreous for 6 months after intravitreal administration.

Dexamethasone implant can lead to retinal nerve fiber layer and optic nerve damage by both increasing intraocular pressure and its direct effect on neural tissue during the effective 6-month period.
