25G与27G玻璃体切割手术治疗孔源性视网膜脱离的疗效及安全性比较分析

目的:比较分析25G与27G平坦部玻璃体切除术(PPV)治疗孔源性视网膜脱离的疗效及安全性。方法:选取在眼病医院进行PPV治疗的87例孔源性视网膜脱离患者临床资料,将行25G PPV治疗的患者设为25G组(49例),行27G PPV治疗的患者设为27G组(38例),比较两组手术时间、手术前后眼压、手术前后最佳矫正视力(BCVA)、视网膜复位率及安全性。结果:25G组手术时间与27G组比较,差异无统计学意义。25G组手术前、术后1 d、7 d、1个月和3个月眼压和BCVA与27G组比较,差异均无统计学意义。25G组视网膜复位率与27G组比较差异无统计学意义;25G组晶状体后囊损伤、医源性视网膜裂孔、结膜下硅油颗粒漏出和高眼压发生率与27G组比较,差异均无统计学意义;27G组低眼压发生率低于25G组,其差异有统计学意义(x2=4.131,P<0.05)。结论:25G和27G PPV治疗孔源性视网膜脱离均有较好效果,且27G PPV相比于25G PPV安全性更高。

Comparative analysis on the curative effect and safety of 25G and 27G PPV in curing rhegmatogenous retinal detachment

Objective:To compare the curative effect and safety of 25G and 27G pars plana vitrectomy(PPV)in curing rhegmatogenous retinal detachment.Methods:The clinical data of 87 patients with rhegmatogenous retinal detachments who underwent PPV treatment in hospital were selected.49 patients who underwent 25G PPV treatment were included in 25G group,and 38 patients who underwent 27G PPV were included in 27G group.The operation time,intraocular pressure before and after surgery,best corrected visual acuity(BCVA)before and after surgery,retinal reduction rate and safety between the two groups were compared.Results:There was no significant difference in operation time between 25G group and 27G group.There were no significant differences in intraocular pressure and BCVA before surgery,at 1the day,7th days,1th month and 3th month after surgery between the two groups.There was no significant difference in retinal reduction rate between 25G group and 27G group.There were no significant in the incidences of posterior capsule injury of crystalline lens,iatrogenic retinal tear,leakage of subconjunctival silicone oil particles and high intraocular pressure between the two groups.The incidence of low intraocular pressure of 25G group was significantly higher than that of 27G group(x2=4.131,P<0.05).Conclusion:Both 25G and 27G PPV have better effect in treating rhegmatogenous retinal.And the safety of 27G PPV is higher than that of 25G PPV.
