PURPOSE
To investigate whether targeted retinal photocoagulation (TRP) of peripheral non-perfused areas (NPAs) could prevent the recurrence of macular oedema (ME) due to branch retinal vein occlusion (BRVO) after intravitreal bevacizumab injection (IVB).
METHODS
Eyes received 1.25 mg IVB only (IVB group) or combined with TRP (IVB + TRP group) of NPAs, more than 5 disc areas identified by fluorescein angiography in the patients with ME secondary to BRVO. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) determined by optical coherence tomography were measured every month for 6 months.
RESULTS
Thirty-eight patients were enrolled and randomized to IVB group (n = 19) and IVB + TRP group (n = 19). Both groups showed similar thinning in CRT at 1 week after IVB, IVB + TRP group maintained thinner retina at 2 (p = 0.0072) and 3 (p = 0.0086) months compared with IVB group in whom turned to thickened almost back to baseline at 3 months. The number of reinjections in IVB group (1.58 ± 0.69) was significantly greater (p = 0.0025) than that in IVB + TRP group (0.83 ± 0.62). BCVA significantly improved at 6 month in IVB + TRP group (p = 0.015), but not in IVB group.
CONCLUSION
TRP of NPAs reduced the amount of ME recurrence following IVB compared to IVB alone.
目的
研究对周边无灌注区(NPA)进行靶向视网膜光凝(TRP)是否能预防玻璃体内注射贝伐单抗(IVB)后视网膜分支静脉阻塞(BRVO)所致黄斑水肿(ME)的复发。
方法
对于继发于BRVO的ME患者,通过荧光素血管造影确定超过5个视盘面积的NPA,仅接受1.25mg IVB治疗的眼(IVB组)或联合TRP治疗的眼(IVB + TRP组)。连续6个月每月测量最佳矫正视力(BCVA)和光学相干断层扫描测定的中心视网膜厚度(CRT)。
结果
38例患者入组并随机分为IVB组(n = 19)和IVB + TRP组(n = 19)。IVB后1周两组CRT均有相似程度变薄,与IVB组相比,IVB + TRP组在2个月(p = 0.0072)和3个月(p = 0.0086)时视网膜维持较薄状态,而IVB组在3个月时几乎增厚回到基线水平。IVB组再次注射的次数(1.58±0.69)显著多于IVB + TRP组(0.83±0.62)(p = 0.0025)。IVB + TRP组在6个月时BCVA显著改善(p = 0.015),而IVB组未改善。
结论
与单纯IVB相比,对NPA进行TRP可减少IVB后ME的复发量。
