Most patients needing diabetic tractional retinal detachment (TRD) surgery are working-age adults that drive and participate in other vision-dependent activities of daily living. We sought to determine the proportion of patients that achieve functional visual acuity (VA) based on the World Health Organization (WHO) definition of ‘low vision’ (≤ 20/80) and US driving standards (≥ 20/40) after vitrectomy for diabetic TRD. In this 10-year retrospective review, consecutive patients who underwent primary vitrectomy for TRD from proliferative diabetic retinopathy were studied. 240 eyes in 203 patients met criteria for analysis (38 eyes were lost to follow up at 3 months; 68 at 12 months; 146 at 60 months). While most patients (nearly 80%) having TRD surgery had low vision pre-op, almost half attained VA that was > 20/80 five years post-op. Those most likely to achieve significant visual improvement (p < 0.0001) had concomitant vitreous hemorrhage pre-op. Only 6% of eyes met the US minimum driving standard before surgery based on VA compared to 28% after vitrectomy however this study did not examine visual fields which could warrant additional assessment depending on local requirements. In summary, significant gains in visual acuity are seen after vitrectomy for diabetic TRD that can result in functional improvement in activities of daily living.

大多数需要糖尿病牵引性视网膜脱离 (TRD) 手术的患者是工作年龄的成年人，他们驾驶和参与其他依赖视觉的日常生活活动。我们试图根据世界卫生组织 (WHO) 的“低视力”定义 (≤ 20/80) 和美国驾驶标准 (≥ 20/40) 确定玻璃体切除术后实现功能性视力 (VA) 的患者比例糖尿病 TRD。在这项为期 10 年的回顾性研究中，研究了因增殖性糖尿病视网膜病变而因 TRD 接受初次玻璃体切除术的连续患者。203 名患者中的 240 只眼符合分析标准（38 只眼在 3 个月时失访；12 个月时 68 眼；60 个月时 146 只眼）。虽然大多数接受 TRD 手术的患者（近 80%）在术前视力较低，但几乎一半的患者在术后五年达到了 > 20/80 的 VA。p  < 0.0001) 术前伴有玻璃体积血。只有 6% 的眼睛在基于 VA 的手术前符合美国最低驾驶标准，而玻璃体切除术后为 28%，但是该研究没有检查视野，这可能需要根据当地要求进行额外评估。总之，糖尿病 TRD 玻璃体切除术后视力显着提高，可导致日常生活活动的功能改善。
