  • Title: The effect of oral acetazolamide on cystoid macular edema in hydroxychloroquine retinopathy: a case report.
    Author: Hong EH, Ahn SJ, Lim HW, Lee BR.
    Journal: BMC Ophthalmol; 2017 Jul 12; 17(1):124. PubMed ID: 28701214.
    Abstract:
    BACKGROUND: Hydroxychloroquine (HCQ) retinopathy can accompany other retinal complications such as cystoid macular edema (CME), which leads to central visual loss. We report a case of CME with HCQ retinopathy that improved with the use of oral acetazolamide, and discussed the possible mechanisms of CME in HCQ retinopathy using multimodal imaging modalities. CASE PRESENTATION: A 62-year-old patient with systemic lupus erythematosus (SLE) and HCQ retinopathy developed bilateral CME with visual decline. Fluorescein angiography (FA) showed fluorescein leakage in the macular and midperipheral area. After treatment with oral acetazolamide (250 mg/day) for one month, CME was completely resolved, best corrected visual acuity (BCVA) improved from 20/50 to 20/25, and FA examination showed decreased dye leakage in the macular and midperipheral areas. CONCLUSIONS: In cases of vision loss in HCQ retinopathy, it is important to consider not only progression of maculopathy, but also development of CME, which can be effectively treated with oral acetazolamide.
