玻璃体切割联合白内障超声乳化术后高眼压临床观察

目的探讨玻璃体切割联合白内障超声乳化术(PPV Phaco)术后高眼压的发生率和危险因素。方法对83例(85只眼)行PPV Phaco联合手术患者的临床资料进行回顾性分析,高眼压的诊断标准为非接触式眼压计眼压≥25 mmHg。结果85只眼中有27只眼术后发生高眼压,发生率31.8%。大多数术后高眼压发生在术后3 d内(22只眼,占81.5%)。27只眼中23只眼高眼压在1周内得以缓解。增生性糖尿病视网膜病变患眼术后高眼压发生率为50%,与其他疾病高眼压发生率比较,差别有显著性(x~2=4.303,P=0.038);术中联合巩膜外环扎、联合硅油充填、联合弥漫视网膜光凝及未植入IOL眼术后高眼压的发生率,分别与未联合巩膜外环扎、未联合硅油填充、未联合弥漫视网膜光凝及植入IOL眼术后高眼压发生率比较,差别有显著性(P<0.05)。结论术后高眼压是PPV Phaco联合手术常见并发症,发生率主要与原发病的种类及联合术式相关。

Clinical observation of ocular hypertension after pars plana vitrectomy combined with phacoemulsification

Objective To investigate the intraocular pressure(IOP)elevation in patients who have undergone pars plana vitreetomy(PPV)combined with phacoemulsification.Method 83 patients(85 eyes)who underwent PPV combined with phaeoemulsification were reviewed.Ocular hypertension was defined as IOP 25mmHg or more by non-touch tonometry examination.Results Twenty-seven eyes presented ocular hypertension after operation(31.8 %).Among them the IOP occurred mostly within 3 days(22eyes,81.5%).In 23 eases(23 eyes)IOP returned to normal in lweck after treatment.The patients suffered from the PDR were more likely to have IOP elevation than other patients in our study (50%,P<0.051.Placement of a scleral buckle,use of silicone oil injection,scatters endophotocoagulation intraopera- tively and without intraocular lens implantation was related to the postvitrectomy IOP elevation(P<0.05).Conclusion IOP elevation was a common complication of PPV combined with phaeoemulsification.The incidence of ocular hypertension was related to certain primary eye diseases and combined ocular procedures.
