To investigate long-term outcomes and their predictive factors in Chinese patients with proliferative diabetic retinopathy (PDR) after vitrectomy.
Retrospective and observational.
PDR patients who underwent vitrectomy in a tertiary eye hospital from 2010 to 2020 were enrolled. The cumulative incidences of re-vitrectomy in the primary eye, vitrectomy in the contralateral eye, low vision (< 0.3 Snellen), and postoperative complications were calculated.
A total of 1094 patients were included in the analysis. The 1-, 3-, and 5-year cumulative incidences for low vision in both eyes were 18.9%, 34.7%, and 44.4%, respectively. The 1-, 5-, and 10-year cumulative incidences for re-vitrectomy in the primary eye were 7.4%, 9.9%, and 9.9%, respectively, and for vitrectomy in the contralateral eye were 31.0%, 62.7%, and 79.5%, respectively. Vitrectomy in the contralateral eye was associated with younger age (hazard ratio [HR] = 0.99, 95% confidence interval [CI] 0.98-0.99), higher glycated hemoglobin (HR = 1.17, 95% CI 1.08-1.27), no preoperative photocoagulation (HR = 0.55, 95% CI 0.39-0.78), severer diabetic retinopathy level (HR = 2.28, 95% CI 1.56-3.33), and poorer preoperative vision (HR = 1.35, 95% CI 1.14-1.61). The cumulative postoperative incidences of the primary eye at 1, 5, and 10 years were 5.7%, 9.9%, and 9.9% for vitreous hemorrhage, 4.2%, 5.1%, and 5.1% for retinal detachment, and 2.8%, 6.2%, and 8.1% for neovascular glaucoma, respectively.
This study reported a comprehensive post-vitrectomy incidence and predictive factors in Chinese PDR patients in a long-term follow up. This would aid in the clinical understanding of this lifelong disease.
研究中国增殖性糖尿病视网膜病变（PDR）患者玻璃体切除术后的长期预后及其预测因素。
回顾性观察研究。
纳入2010年至2020年在一家三级眼科医院接受玻璃体切除术的PDR患者。计算术眼再次玻璃体切除术、对侧眼玻璃体切除术、低视力（<0.3 Snellen）及术后并发症的累积发生率。
共1094例患者纳入分析。双眼低视力的1年、3年和5年累积发生率分别为18.9%、34.7%和44.4%。术眼再次玻璃体切除术的1年、5年和10年累积发生率分别为7.4%、9.9%和9.9%，对侧眼玻璃体切除术的累积发生率分别为31.0%、62.7%和79.5%。对侧眼玻璃体切除术与年龄较小（风险比[HR]=0.99，95%置信区间[CI] 0.98-0.99）、糖化血红蛋白水平较高（HR=1.17，95%CI 1.08-1.27）、术前未行光凝治疗（HR=0.55，95%CI 0.39-0.78）、糖尿病视网膜病变程度较重（HR=2.28，95%CI 1.56-3.33）及术前视力较差（HR=1.35，95%CI 1.14-1.61）相关。术眼玻璃体出血的术后1年、5年和10年累积发生率分别为5.7%、9.9%和9.9%，视网膜脱离的累积发生率分别为4.2%、5.1%和5.1%，新生血管性青光眼的累积发生率分别为2.8%、6.2%和8.1%。
本研究报告了中国PDR患者玻璃体切除术后长期随访的综合发生率及预测因素。这将有助于临床对这种终身疾病的理解。
