The purpose of this study was to evaluate visual outcomes of arteriovenous sheathotomy for macular edema due to branch retinal vein occlusion (BRVO).
The medical records of 45 eyes from 45 patients who had undergone vitrectomy surgery with arteriovenous sheathotomy for BRVO were studied. Forty-five eyes of 45 patients with a BRVO but without intervention were studied as the control group. The best-corrected visual acuity and central macular thickness were compared between the two groups at baseline and at 1, 3, 6, and 12 months postoperatively.
Improvement of best-corrected visual acuity was 0.42 logarithm of the minimum angle of resolution (logMAR) units in the sheathotomy group and 0.22 logMAR units in the control group (P=0.007). The mean postoperative central macular thickness was significantly thinner in the sheathotomy group at 1 month (P=0.01), but not at 3, 6, and 12 months (P=0.75, P=0.81, and P=0.46, respectively). Improvement of best-corrected visual acuity at 12 months was significantly correlated with baseline best-corrected visual acuity, age, duration of symptoms, and sheathotomy (P<0.05).
Arteriovenous sheathotomy for BRVO improves best-corrected visual acuity significantly more than the natural course of the BRVO disease process.
本研究旨在评估视网膜分支静脉阻塞（BRVO）所致黄斑水肿行动静脉鞘膜切开术的视力预后。
对45例因BRVO接受玻璃体切割联合动静脉鞘膜切开术患者的45只眼的病历进行研究。将45例BRVO但未接受干预的患者的45只眼作为对照组。比较两组在基线时以及术后1、3、6和12个月时的最佳矫正视力和中心黄斑厚度。
鞘膜切开术组最佳矫正视力提高了0.42最小分辨角对数（logMAR）单位，对照组提高了0.22 logMAR单位（P = 0.007）。鞘膜切开术组术后1个月时平均中心黄斑厚度明显更薄（P = 0.01），但在3、6和12个月时并非如此（分别为P = 0.75、P = 0.81和P = 0.46）。12个月时最佳矫正视力的改善与基线最佳矫正视力、年龄、症状持续时间和鞘膜切开术显著相关（P < 0.05）。
BRVO行动静脉鞘膜切开术比BRVO疾病自然进程能更显著地提高最佳矫正视力。
