Purpose: To report a case of cytomegalovirus (CMV) retinitis in an immunocompetent adult patient.
Methods: A 61-year-old woman with proven CMV retinitis and no evidence of HIV or other underlying immunodeficiencies was referred.
Results: She was referred with history of recent right eye visual loss. In fundus examination, she had signs of retinal vasculitis. After initial examination, she was found to have CMV retinitis documented by polymerase chain reaction (PCR) analysis of vitreous sample. She had neither underlying risk factor in any assessed work-up nor any concomitant disease in 10 months follow-up. She received intravitreal ganciclovir with good response to treatment.
Conclusion: Ophthalmologists should take into account infectious causes of retinal vasculitis before approaching anti-inflammatory or anti-VEGF therapy.
