Retinal Defects Three Months After Intravitreal Dexamethasone Implant.

Abstract

Intravitreal dexamethasone implants are commonly used to treat macular edema and noninfectious uveitis, and side effects including glaucoma and cataract formation are frequently managed. Rarely, the implant can cause an impact injury. However, this case shows peripheral retinal defects in a vitrectomized eye with abutting dexamethasone intravitreal implant without a flap, operculum, or other evidence of traction, developing 3 months after insertion, excluding the chance of injury from impact. The presence of an intravitreal dexamethasone implant appeared to cause destruction of juxtaposed retinal tissue. This report describes evaluation and management of this previously unreported complication. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:e211-e214.].
