Intravitreal slow-releasing dexamethasone implant for idiopathic neuroretinitis

The purpose of this report is to describe a successful management of idiopathic neuroretinitis with intravitreal dexamethasone implant.

Interventional case report.

A 34-year-old man with an acute painless unilateral vision loss, optic disc swelling, and a macular edema was diagnosed as idiopathic neuroretinitis, and he underwent 0.7 mg dexamethasone intravitreous implant injection. Macular edema responded quickly and visual acuity improved from 20/50 to 20/25 within 2 weeks and to 20/20 within a month. One month after the injection, optic disc edema disappeared. No recurrence occurred and visual acuity was stable at 20/20 during 3 years of follow-up.

Idiopathic neuroretinitis can be treated with intravitreal dexamethasone implant.
