Abstract

PURPOSE
To report the results of arteriovenous adventitial sheathotomy for treatment of macular edema associated with branch retinal vein occlusion. METHODS: Five eyes of five patients underwent arteriovenous adventitial sheathotomy. Patient selection criteria were the best-corrected visual acuity of less than 0.1 and duration of less than 1 month. Pars plana vitrectomy was performed and 23 gauge needle, bent at the tip, was used to cut through the adventitial sheath and separate the arteriole from the underlying venule. Patients were followed postoperatively for 6 months to 1 year, with an average of 9.6 months. RESULTS: In all 5 patients, the best-corrected visual acuity improved to 0.3 to 0.9. Fluorescein angiography demonstrated reperfusion of the retina and lessening of macular edema. CONCLUSION: Arterionvenous adventitial sheathotomy may be beneficial for patients with poor vision secondary to branch retinal vein occlusion.
