 We used peroral carbonic anhydrase inhibitor in 50 eyes of 50 patients of macular edema. It was secondary to branch retinal vein occlusion in 38 eyes and central retinal vein occlusion in 12 eyes. Their ages averaged 63.1±10.7 years. Macular edema was estimated to have been present for 9.0±13.7months. As a standard procedure,acetazolamide was given at the daily dosis of 500mg for 4 weeks followed by tapering. The baseline visual acuity averaged 0.25±0.32. It significantly improved to 0.31±0.39 after 2 weeks of treatment(p=0.04). It further improved to 0.38±0.33 after 2months of treatment. The visual acuity improved by 2 lines or more in 23 eyes(46%). When observed by optical coherence tomography(OCT),the macular edema decreased in 42 eyes(84%). The visual acuity deteriorated in 15 eyes(30%)after discontinuation or decrease in dosage. The findings show that peroral carbonic anhydrase inhibitor may be beneficial for macular edema in about one-half of cases of retinal vein occlusions.
