intravitreal triamcinolone acetonide for treatment of cystoid macular edema due to retinitis pigmentosa; a case report

purpose: 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. conclusion: 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
