背景与目的
确定术前视力（VA）为20/200或更差的患者与术前视力优于20/200的患者相比，激光治疗视网膜分支静脉阻塞（BRVO）所致黄斑水肿的视力结局。
患者和方法
回顾性分析1984 ~ 2003年88例BRVO继发黄斑水肿患者的激光治疗资料。在每次治疗前后和最终治疗后测量平均VA。
结果
所有患者均接受了一到五次激光治疗。56例患者（第1组）的术前VA优于20/200，32例患者（第2组）的术前VA为20/200或更差。第1组患者平均改善0.48行，57%的患者最终VA为20/40或更好。第2组患者平均改善1.69行，20%的患者最终VA为20/40或更好。
结论
继发于BRVO所致黄斑水肿的视力差（20/200或更差）患者对激光治疗反应积极。术前VA水平可以作为预测视力预后的一个有用指标。这些患者应在采用其他更具侵略性的方法之前考虑激光治疗。
BACKGROUND AND OBJECTIVE
To determine the visual outcome of laser treatments for macular edema due to branch retinal vein occlusion (BRVO) in patients with a preoperative visual acuity (VA) of 20/200 or worse compared to patients with a preoperative VA of better than 20/200.
PATIENTS AND METHODS
Records of 88 patients with macular edema secondary to BRVO undergoing laser treatment from 1984 to 2003 were reviewed. Mean VA was measured before and after each treatment and after the final treatment.
RESULTS
All patients received between one and five laser treatments. Preoperative VA was better than 20/200 in 56 patients (group 1) and 20/200 or worse in 32 patients (group 2). Patients in group 1 had a mean improvement of 0.48 lines and 57% had a final VA of 20/40 or better. Patients in group 2 had a mean improvement of 1.69 lines and 20% had a final VA of 20/40 or better.
CONCLUSIONS
Patients with poor VA (20/200 or worse) secondary to macular edema due to BRVO responded positively to laser treatment. The level of preoperative VA can be a useful predictor of visual outcome. These patients should consider laser treatment before alternative, more aggressive approaches.
