Abstract：
Our purpose was to evaluate the efficacy of lateral canthotomy, sub-tenon anesthesia injection, and the use of modified speculum for gaining adequate surgical exposure during surgery for retinopathy of prematurity (ROP). Fourteen eyes of 10 consecutive patients undergoing microincisional vitrectomy surgery (MIVS) for stage 4 and stage 5 ROP were included. There was a significant widening of the palpebral fissure height and length using this technique. No patient developed a lens injury during the surgery. All the canthotomy incisions completely healed at a four-week follow-up visit. This is a safe and effective technique for increasing surgical exposure in cases of ROP requiring vitrectomy.
摘要：
我们的目的是评估外侧角切开术的疗效，肌腱下麻醉注射,以及在早产儿视网膜病变（ROP）手术期间使用改良的窥器获得足够的手术暴露。包括接受4期和5期ROP微切口玻璃体切除术（MIVS）的10例连续患者的14只眼。使用此技术，睑裂的高度和长度显着扩大。手术期间没有患者出现晶状体损伤。在四周的随访中，所有的头角切开术切口完全愈合。这是一种安全有效的技术，可在需要玻璃体切除术的ROP病例中增加手术暴露量。
