目的:分析影响增殖性糖尿病视网膜病变(PDR)玻璃体切除术后视力改善的因素。方法:回顾性分析。收集2014-01/2014-12在马来西亚吉打州,亚罗士打Sultanah Bahiyah医院收治的PDR行玻璃体切除术病例资料,包括1y内患者统计,基线视力(VA)和LogMAR术后最佳矫正视力。使用IBM SPSS Statistics Version 22.0进行数据分析。结果:共103例患者。平均年龄51.2y。在多变量分析中,每个0 logMAR基线VA的1 logMAR术前正偏差与0.859logMAR的术后改善相关(P<0.001)。同样,术前附着的黄斑与玻璃体切除术后的logMAR视力改善相关(b=0.374,P=0.003)。无虹膜新血管和无术后并发症与玻璃体切除术后改善的logMAR视力相关,分别为1.126(P=0.001)和0.377(P=0.005)。无长效眼内填充与玻璃体切除术后logMAR视力改善相关,为0.302(P=0.010)。结论:玻璃体切除术后与视力改善的相关因素是:术前视力较差,黄斑附着,无虹膜新生血管,无术后并发症和未使用长效眼内填充物。了解视力改善的因素将有助于玻璃体视网膜手术的决策。
OBJECTIVE: To analyze the factors that influence the improvement of vision after vitrectomy for proliferative diabetic retinopathy (PDR). Methods: Retrospective analysis. Collect data on cases of PDR undergoing vitrectomy at Sultanah Bahiyah Hospital, Alor Setar, Kedah, Malaysia from January 2014 to December 2014, including best-corrected visual acuity after 1-year patient statistics, baseline visual acuity (VA) and LogMAR . Data analysis using IBM SPSS Statistics Version 22.0. Results: A total of 103 patients. The average age of 51.2y. In multivariate analysis, 1 logMAR preoperative bias for each 0 logMAR baseline VA correlated with postoperative improvement of 0.859 logMAR (P <0.001). Similarly, preoperative attachment of the macula was associated with improved logMAR vision after vitrectomy (b = 0.374, P = 0.003). Non-iris neovascular and postoperative complications were associated with improved logMAR visual acuity after vitrectomy, 1.126 (P = 0.001) and 0.377 (P = 0.005), respectively. Non-long-term intraocular filling was associated with improved logMAR visual acuity after vitrectomy, 0.302 (P = 0.010). CONCLUSIONS: Factors associated with improved vision after vitrectomy were poor preoperative visual acuity, macular attachment, no iris neovascularization, no postoperative complications, and no long-term intraocular fillings. Understanding the factors that improve vision will help make decisions about vitreoretinal surgery.
