玻璃体切除术同期联合白内障超声乳化吸除术治疗PDR

Vitrectomy simultaneously combined with phacoemulsification for treating PDR

目的:探究玻璃体切除术同期联合白内障超声乳化吸除术对PDR患者视力、眼压、CMT及术后并发症的影响。方法:将2015-02/2017-02我院收治的PDR患者90例98眼根据自愿原则分为:A组(玻璃体切除术同期联合晶状体切除术,45例50眼),B组(玻璃体切除术同期联合白内障超声乳化吸除术,45例48眼)。术后随访6mo,比较两组视力改善情况、手术前后眼压、CMT及术后并发症发生率。结果:术后B组视力改善情况显著优于A组,视力提高率显著高于A组(P<0.05);两组术前、术后眼压均无差异(P>0.05);术后两组CMT均有显著降低,两组CMT无差异(P>0.05);B组INV、囊膜混浊、角膜水肿、瞳孔挟持、硬性渗出术后并发症发生率均显著低于A组(P<0.05)。结论:玻璃体切除术同期联合白内障超声乳化吸除术治疗PDR疗效明显,可促进患者术后视力恢复,降低CMT,且并发症风险较低。

·AIM:To explore the effects of vitrectomy simultaneously combined with phacoemulsification on visual acuity,intraocular pressure(IOP),central macular thickness(CMT)and postoperative complications in patients with proliferative diabetic retinopathy(PDR).·METHODS:Totally 90 PDR patients(98 eyes)admitted to the hospital from February 2015 to February 2017 were divided into two groups according to the principle of voluntariness:group A(vitectomy simultaneously combined with lensectomy,45 cases,50 eyes)and group B(vitrectomy simultaneously combined with phacoemulsification,45 cases,48 eyes).The follow-up period was 6 mo.The visual acuity improvement,IOP before and after surgery,CMT and incidence of postoperative complications were compared between the two groups.·RESULTS:The visual acuity improvement after surgery in group B was significantly better than that in group A,and the improving rate of visual acuity was significantly higher than that in group A(P<0.05).There was no significant difference in IOP before and after surgery between the two groups(P>0.05).The CMT after surgery was decreased significantly in both groups.CMT in both groups was not statistically different(P>0.05).The incidence rates of postoperative complication ssuch as INV,capsule turbidity,corneal edema,pupil hijacking and hard exudate in group B were significantly lower than those in group A(P<0.05).·CONCLUSION:Vitrectomy simultaneously combined with phacoemulsification have obvious efficacy on PDR,which promote recovery of postoperative visual acuity,reduce CMT,and it has low risk of postoperative complications.
