Effect of intravitreal dexamethasone implant on the contralateral eye: a case report.

Objective: To describe the effect of unilateral intravitreal injection of 0.7-mg dexamethasone implant on the other eye.

Methods: Interventional case report and literature review.

Results: A 54-year-old woman with bilateral, refractory, clinically significant macular edema was given an intravitreal injection of 0.7-mg dexamethasone sustained release implant in the right eye. The central foveal thickness improved in both the eyes with recurrence of edema after 16 weeks in both the eyes.

Conclusions: An intravitreal dexamethasone injection seems to have bilateral effect after unilateral injection.
