Cytomegalovirus retinitis following dexamethasone intravitreal implant.

ABSTRACT

PURPOSE: To describe a case of Cytomegalovirus (CMV) Retinitis in an immunocompetent patient following Dexamethasone Intravitreal Implant (DII). OBSERVATIONS Retrospective chart review of a single patient. An 80-year-old immunocompetent male presented with floaters in his left eye 10 weeks after his DII. He was noted to have a visual acuity of 20/1200 in his left eye and a panuveitis with CMV retinitis. The patient underwent a vitreous biopsy and given immediate intravitreal foscarnet and an ongoing management regimen of oral valganciclovir for two months. His vision improved to 20/200 and his CMV retinitis resolved. CONCLUSION AND IMPORTANCE DII can trigger CMV retinitis in immunocompetent patients.
