Cytomegalovirus retinitis in an immunocompetent host after complicated cataract surgery.

Purpose: To report a case of an immunocompetent patient who developed cytomegalovirus (CMV) retinitis after complicated cataract surgery resulting in aphakia.

Observations: A 67-year-old man with type 2 diabetes developed retinitis six months after cataract surgery that resulted in aphakia. Anterior chamber DNA testing was positive for CMV. Comprehensive systemic work-up revealed no immune insufficiency. The retinitis was successfully treated with intravitreal foscarnet and extended oral valgancyclovir treatment, however, he subsequently developed rhegmatogenous retinal detachment.

Conclusion And Importance: CMV retinitis may occur in immunocompetent patients in the setting of aphakia and prolonged topical steroid use.
