Tóm tắt

The treatment of recurrent cystoid macular edema associated with acute retinal necrosis is challenging due to the concern that treatment with intravitreal steroids may reactivate the retinitis. An immunocompetent patient diagnosed with acute retinal necrosis was treated with oral valacyclovir and intravitreal injections of foscarnet. Giant tears in her retina necessitated a vitrectomy with silicone oil. She developed cystoid macular edema after the removal of the silicone oil. The edema responded to high-dose prednisolone but recurred when the dose was tapered to 20 mg daily. Under close surveillance and increased antiviral medication, she was treated with a dexamethasone implant with complete resolution of the edema. Unfortunately, the edema recurred, and the treatment had to be repeated. Over 18 months, she received five dexamethasone implants without recurrence of the viral retinitis. This case shows successful treatment of recurring cystoid macular edema following acute retinal necrosis with repeated intravitreal dexamethasone implants in a patient receiving valacyclovir maintenance treatment.
