孔低位在孔源性视网膜脱离玻璃体切除手术中的应用

Application of hole lower-position in vitrectomy for rhegmatogenous retinal detachment

目的评价孔低位在孔源性视网膜脱离玻璃体切除手术中的应用效果。方法104眼孔源性视网膜脱离病例实施25G玻璃体切除视网膜复位术,随机分成对照组和观察组,对照组采用常规手术体位,观察组采用孔低位,观察并比较两组病例手术时间、术中情况、术中术后并发症、术后视力、术后眼压、视网膜复位率。结果对照组手术时间:(41.2±5.1)min,观察组手术时间:(37.3±4.8)min,两组差异有统计学意义(P<0.05);观察组术后最佳矫正视力提高5个字母以上的病例多于对照组,视力预后优于对照组,差异有统计学意义(P<0.05)。结论孔低位应用在孔源性视网膜脱离玻璃体切除手术中能够扩大手术视野,缩短手术时间,改善视力预后。

Objective To evaluate the effect of hole lower-position in vitrectomy(PPV)for rhegmatogenous retinal detachment(RRD).Methods 104 eyes of RRD patients treated with 25GPPV retinal reattachment were randomly divided into control group and observation group.Routine operation posture was used in control group,and hole lower-position was used in observation group.We observed and compared operation time,intraoperative condition,intraoperative and postoperative complications,postoperative visual acuity,postoperative intraocular pressure and retinal reattachment rates between the two groups.Results The mean operation time was 41.2±5.1 minutes in control group and 37.3±4.8 minutes in observation group(P<0.05).The number of patients with postoperative best corrected visual acuity improved more than 5 letters in the observation group was more than that in control group.The prognosis of visual acuity in observation group was better than that in control group which showed statistically significant differences(P<0.05).Conclusion The application of hole lower-position in vitrectomy for rhegmatogenous retinal detachment can shorten operation time and improve visual prognosis.
