Cytomegalovirus necrotizing retinitis in an immunocompetent patient: A case report.

This is the case of a necrotizing retinitis associated with occlusive retinal vasculitis due to cytomegalovirus (CMV) in an immunocompetent patient with complex diagnosis and management, but with resolution after the start of appropriate antiviral therapy, with subsequent control of intraocular inflammation and visual recovery. CMV was confirmed as the pathogen using the polymerase chain reaction (PCR) assay of aqueous humor samples.
