With a resurgence of syphilis with human immunodeficiency virus (HIV) infection in last few years, various ocular manifestations of syphilis have been described in literature. This case report described an HIV-positive patient on anti-retroviral therapy who was diagnosed and treated for posterior uveitis secondary to ocular syphilis in the recent past presented to our clinic with cystoid macular edema (CME). CME, which did not respond to periocular corticosteroid, resolved with intravitreal sustained release dexamethasone implant. There was a recurrence CME 9 months later and repeat injection of intravitreal implant showed complete resolution. A long-term follow-up did not reveal reactivation of the infection with intravitreal corticosteroid. Intravitreal sustained release dexamethasone implant can be an effective treatment for refractory CME in patients with regressed syphilitic uveitis.
