评估糖尿病黄斑水肿 (DMO) 的视力 (VA) 结果和抗血管内皮生长因子 (抗 VEGF) 治疗强度。使用汇总的去识别化电子病历数据库 (Vestrum Health) 对 2013 年至 2018 年未接受治疗的 DMO 患者进行回顾性分析。第 1 年,28658 名患者眼睛平均接受了 6.4 次抗 VEGF 注射,平均增加了 +4.2 个字母(平均增加的 95% 置信区间:+4.0 至 +4.5 个字母,p<0.001)。当按抗 VEGF 药物和 2013-2018 年进行分层时,注射频率或 1 年 VA 变化没有产生有临床意义的差异。 1 年时,50% 的眼睛接受了 ≤6 次注射,而<20% 的眼睛接受了 10-13 次注射,即每月治疗一次。 1 年时获得的平均字母通常与抗 VEGF 注射的平均次数呈线性关系(超过两次注射)。基线视力良好(≥20/40)的眼睛通常在 1 年时有视力丧失的风险;那些有中度严重基线损伤(20/70 至 20/200)且接受 ≥10 次注射的患者平均改善 +10.3 个字母。在临床实践中,与随机临床试验中的患者相比,DMO 患者接受的抗 VEGF 注射次数较少,且视力改善较差。视力结果与 1 年时的治疗强度相关,上限效应与基线 VA 相关。
To assess visual acuity (VA) outcomes and antivascular endothelial growth factor (anti-VEGF) treatment intensity in diabetic macular oedema (DMO). Retrospective analysis was performed in treatment-naïve patients with DMO from 2013 to 2018 using a database of aggregated de-identified electronic medical records (Vestrum Health). At 1 year, 28 658 patient eyes underwent a mean of 6.4 anti-VEGF injections, gaining a mean of +4.2 letters (95% confidence interval for mean gain: +4.0 to +4.5 letters, p<0.001). When stratified by anti-VEGF medication and by years 2013–2018, no clinically meaningful differences in injection frequency or 1-year VA change resulted. At 1 year, 50% of eyes received ≤6 injections, while <20% received 10–13 injections, representing monthly treatment. Mean letters gained at 1 year generally showed a linear relationship with mean number of anti-VEGF injections, beyond two injections. Eyes with good baseline VA (≥20/40) generally were at risk of VA loss at 1 year; those with moderately severe baseline impairment (20/70 to 20/200) who received ≥10 injections improved by a mean of +10.3 letters. In clinical practice, patients with DMO undergo fewer anti-VEGF injections and exhibit worse visual gains compared with patients in randomised clinical trials. Visual outcomes correlate with treatment intensity at 1 year, with ceiling effects related to baseline VA.
