To analyze the role of endolaser around macular hole in managing associated retinal detachment in patients with high myopia.
Review of medical records of 25 consecutive eyes of 25 patients with at least 5.00 diopters of myopia who underwent primary pars plana vitrectomy and fluid-gas exchange. In the first half of the study period, one row of contiguous argon green endolaser was routinely applied over the retinal edge of the macular hole (EL group). In the second half of the study period, endolaser was not applied around any macular hole (NEL group). Demographic information, intraoperative and postoperative complications, and final visual acuities and retinal reattachment rates were studied.
The mean (+/-SD) refractive error was -11.8 +/- -3.5 diopters (D) for the EL group and -11.6 +/- -5.4 D for the NEL group. The mean axial length was 29.0 +/- 1.8 mm for the EL group and 28.3 +/- 1.7 mm for the NEL group. The primary anatomic success was 62.5% (10/16) and 77.8% (7/9) in the EL and NEL groups, respectively. No statistically significant difference was found in preoperative, postoperative, or change in best-corrected visual acuities between the two groups.
Endolaser around the macular hole after pars plana vitrectomy and internal gas tamponade may not affect the anatomic or visual outcome in primary retinal detachment secondary to a highly myopic macular hole.
分析黄斑裂孔周围内激光在治疗高度近视患者相关视网膜脱离中的作用。
回顾25例至少有5.00屈光度近视患者的25只连续眼睛的病历，这些患者接受了一期玻璃体切除术和液-气交换。在研究期的前半段，常规在黄斑裂孔的视网膜边缘应用一排连续的氩绿内激光（EL组）。在研究期的后半段，未在任何黄斑裂孔周围应用内激光（NEL组）。研究了人口统计学信息、术中及术后并发症、最终视力和视网膜复位率。
EL组平均（±标准差）屈光不正为-11.8±-3.5屈光度（D），NEL组为-11.6±-5.4 D。EL组平均眼轴长度为29.0±1.8 mm，NEL组为28.3±1.7 mm。EL组和NEL组的初次解剖成功率分别为62.5%（10/16）和77.8%（7/9）。两组术前、术后或最佳矫正视力变化均无统计学显著差异。
玻璃体切除术后黄斑裂孔周围内激光及眼内气体填塞可能不会影响高度近视性黄斑裂孔继发的原发性视网膜脱离的解剖或视觉预后。
