Abstract
OBJECTIVE
To report a case of cytomegalovirus (CMV) retinitis in an HIV-negative, iatrogenically immunosuppressed patient with chronic uveitis following intravitreal triamcinolone acetonide (IVTA).
METHODS
Observational case report.
METHODS
A 56-year-old female with chronic idiopathic panuveitis on azathioprine received a single 4-mg IVTA injection for macular edema and presented after 6 months with severe retinitis.
RESULTS
CMV was confirmed by polymerase chain reaction of vitreous fluid. The retinitis responded well to intravitreal ganciclovir, but she developed a rhegmatogenous retinal detachment and underwent vitrectomy with silicone oil tamponade.
CONCLUSIONS
Sight-threatening CMV retinitis may develop in HIV-negative, immunosuppressed individuals after IVTA. Regular fundoscopy for up to 9 months after IVTA is recommended.
