Intravitreal Triamcinolone Acetonide for Treatment of Cystoid Macular Edema due to Retinitis Pigmentosa; a Case Report

To report treatment with intravitreal triamcinolone acetonide (IVTA) in a patient with cystoid macular edema (CME) secondary to retinitis pigmentosa (RP).Case Report: A 22-year-old male patient with RP presented with progressive visual loss. Visual acuity was 9/10 in the right eye and 10/10 in the left eye without refractive error. Examination revealed CME in the right eye. After failure of treatment with oral acetazolamide and reduction of visual acuity to 6/10, intravitreal injection of 4 mg triamcinolone acetonide was performed in the right eye. Six weeks later, macular edema resorbed and visual acuity improved to 10/10.

IVTA may be useful for selected cases of CME related to retinitis pigmentosa. Further study on a larger number of patients is warranted to assess the efficacy of this treatment.
