To evaluate long-term visual outcome of arteriovenous adventitial sheathotomy in BRVO-induced macular edema.
The visual outcomes of 8 patients following vitrectomy with arteriovenous adventitial sheathotomy for BVO-induced macular edema (surgery group) were retrospectively evaluated. The three-year post-operative visual acuity of the surgery group was compared with that of the conservatively managed controls.
All patients were followed for a minimum of 36 months. Mean BCVA (logMAR) in the surgery group changed from 1.10+/-0.34 to 1.19+/-0.70 and to 0.80+/-0.36 at 12 and 36 months, respectively (p=0.959 at 12 months, p=0.018 at 36 months). In the control group, visual acuity improved from 1.15+/-0.43 to 0.43+/-0.44 and to 0.43+/-0.39 at 12 and 36 months, respectively (p=0.015 at 12 months, at p=0.003 at 36 months). A strong trend toward better visual acuity at 12 months and final examination was observed for controls. (surgery vs. control group, p=0.052 at 12 months, p=0.066 at 36 months).
Considering the favorable natural course of BVO and the unproven effect of reperfusion on macular edema, surgical efficacy of arteriovenous adventitial sheathotomy requires further evaluation.
评估视网膜分支静脉阻塞（BRVO）所致黄斑水肿行动静脉外膜鞘切开术的长期视力预后。
回顾性评估8例因BRVO所致黄斑水肿行玻璃体切除术联合动静脉外膜鞘切开术患者（手术组）的视力预后。将手术组术后3年的视力与保守治疗对照组的视力进行比较。
所有患者至少随访36个月。手术组平均最佳矫正视力（logMAR）在12个月和36个月时分别从1.10±0.34变为1.19±0.70和0.80±0.36（12个月时p = 0.959，36个月时p = 0.018）。对照组视力在12个月和36个月时分别从1.15±0.43改善为0.43±0.44和0.43±0.39（12个月时p = 0.015，36个月时p = 0.003）。在12个月和最终检查时，观察到对照组有视力更好的强烈趋势。（手术组与对照组比较，12个月时p = 0.052，36个月时p = 0.066）。
考虑到BRVO的良好自然病程以及再灌注对黄斑水肿的效果未经证实，动静脉外膜鞘切开术的手术疗效需要进一步评估。
