The purpose of this study was to compare pars plana vitrectomy (PPV) with 1000 cSt silicone oil endotamponade and PPV with densiron endotamponade for retinal detachment with macular hole and posterior staphyloma in highly myopic eyes.
In a prospective study, 30 eyes of 30 patients were randomly assigned to PPV and densiron (n = 15) or PPV with silicone oil (n = 15). All eyes had laser photocoagulation of the macular hole rim after PPV. Silicone oil or densiron was removed 12 weeks after surgery. Patients were followed-up for 6 months after oil removal.
In the densiron group, the retinal reattachment rate was 100% with densiron in situ and 87% after its removal, and in the silicone oil group, the retinal reattachment rate was 67% with silicone oil in situ and 53.4% after oil removal. Thus, PPV with densiron had a better anatomical success rate than silicone oil (P = 0.04 with endotamponade and P = 0.05 after endotamponade removal). In both groups, paired comparison of preoperative and postoperative best-corrected visual acuity was not statistically significant (P = 0.08).
Pars plana vitrectomy with densiron is a preferred surgical procedure for the repair of macular hole retinal detachment in highly myopic eyes with posterior staphyloma.
本研究旨在比较伴有黄斑裂孔和后葡萄肿的高度近视眼中行巩膜扣带术联合 1000 cSt 硅油或重水内填充的疗效。
前瞻性研究，30 例（30 眼）患者随机分为巩膜扣带术联合重水（n=15）或硅油内填充（n=15）组。所有患者均行巩膜扣带术后黄斑裂孔环扎激光光凝。术后 12 周时取出硅油或重水。硅油取出后随访 6 个月。
重水组视网膜复位率为填充在位时 100%，取出后 87%；硅油组分别为 67%和 53.4%。因此，巩膜扣带术联合重水的解剖复位率优于硅油（在位时 P=0.04，取出后 P=0.05）。两组患者术前术后最佳矫正视力比较差异均无统计学意义（P=0.08）。
伴有后葡萄肿的高度近视眼中行巩膜扣带术联合重水内填充是治疗黄斑裂孔性视网膜脱离的一种较好的方法。
