增殖型糖尿病视网膜病变玻璃体切割术后视力不良的相关因素研究

目的 调查增殖型糖尿病视网膜病变玻璃体切割术后视力低于0.1的发生频率及相关因素.方法 回顾性分析95例120只眼增殖型糖尿病视网膜病变行玻璃体切割手术治疗患者的临床资料,在术后视力低于0.1和大于等于0.1两群间,对可能影响术后视力的相关因素进行比较.结果 37只眼(31%)术后视力低于0.1.根据单变量分析,术后视力不良与术前黄斑脱离、眼内填充物填充、术后高眼压及术前未进行全视网膜光凝治疗具有较高的相关性.根据多变量分析,术后视力不良与术前黄斑脱离及术后高眼压的关系更为密切.结论 增殖型糖尿病视网膜病变玻璃体切割术后视力低于0.1与术前黄斑脱离及术后高眼压密切相关.

Predisposing factors to the poor visual acuity after vitrectomy in the treatment of proliferative diabetic retinopathy

Objective To determine the incidence and predisposing factors for the poor visual acuity of less than 0.1 after vitrectomy in the treatment of proliferative diabetic retinopathy (PDR). Methods The clinical data of 95 cases (120 eyes) of PDR patients treated with vitrectomy were analyzed retrospectively. Compared the potential predisposing factors to the poor visual acuity between the two groups: one group with postoperative visual acuity of less than 0.1, the other group with postoperative visual acuity of 0.1 or more than 0.1. Results There were 37 (31%) eyes with postoperative visual acuity of less than 0.1. Univariate analysis revealed that there were association between the poor postoperative visual acuity and preoperative macular detachment、intraocular tamponade, postoperative high intraocular pressure, with no preoperative panretinal photocoagulation. Multivariate analysis revealed that there were great association between the poor postoperative visual acuity and preoperative macular detachment, postoperative high intraocular pressure. Conclusions The poor visual acuity of less than 0.1 after vitrectomy in the treatment of PDR has great association with preoperative macular detachment, postoperative high intraocular pressure.
