Abstract |
PURPOSE We report a case of cytomegalovirus (CMV) retinitis following placement of an intravitreal dexamethasone implant in an immunocompetent patient diagnosed with non-infectious uveitis. CASE SUMMARY: A 60-year-old woman was referred to our hospital for recurrent anterior uveitis. Fundus examination and fluorescein angiography showed dense vitritis, but no definite retinal infiltration. After laboratory examinations, the patient was diagnosed with non-infectious panuveitis. Uveitis was much improved after the patient started taking oral steroid medication. However, the patient complained of systemic side effects from the oral steroids. Medication was stopped, and an intravitreal dexamethasone implant was fitted to address worsening inflammation. Two months later, perivascular retinal infiltration developed and vitritis recurred. Viral retinitis was suspected, and the patient underwent diagnostic vitrectomy adjunctive with intravitreal ganciclovir injection. Polymerase chain reaction of vitreous fluid confirmed the diagnosis of CMV retinitis. The patient has remained inflammation-free for more than 20 months after vitrectomy, single ganciclovir injection, and 2 months of oral valganciclovir medication. CONCLUSIONS: This is a case report of CMV retinitis following placement of an intravitreal dexamethasone implant in an immunocompetent patient without any risk factors or previous history of immunosuppression. Potential risk factors for CMV retinitis should be evaluated and careful follow-up should be performed when intravitreal dexamethasone injections are unavoidable for the treatment of non-infectious uveitis. |
