Abstract
This report describes a case of central serous chorioretinopathy following intravitreal triamcinolone acetonide injection. A 42-year-old man presented with a 4-month history of decreased visual acuity (0.4) in his left eye. The left eye demonstrated macular edema due to branch retinal vein occlusion. Triamcinolone acetonide 4 mg/ 0.1 mL was injected intravitreally to treat the macular edema. Pigmentary retinal discoloration, retinal pigment epithelium leakage and a slight neurosensorial detachment with cystoid macular edema at the temporal macula were present prior to intravitreal triamcinolone injection. Three weeks after injection, visual acuity had decreased to 0.2 and metamorphopsies appeared in the left eye. A sharply demarcated serous macular elevation and a progressively increasing hyperfluorescence of the pre-existing leakage point led to the diagnosis of “exacerbation of the pre-existing asymptomatic central serous chorioretinopathy” following intravitreal triamcinolone injection. Macular elevation spontaneously resolved by the 4th month post-injection. At the 6th month, the patient experienced recurrence of a small serous detachment at the temporal macula. Central serous chorioretinopathy exacerbation may arise as a complication of intravitreal triamcinolone acetonide injection.
