目的:探讨视网膜内层结构紊乱(DRIL)对糖尿病性黄斑水肿(DME)患者接受抗血管内皮生长因子(VEGF)治疗后视力恢复的影响。方法:采用前瞻性队列研究设计,连续纳入2022年3月至2023年4月于天津市眼科医院就诊的132例单眼DME患者(共132眼),每例患者仅选取1眼;根据治疗前光学相干断层扫描(OCT)测量的DRIL长度分为3组:A组(无DRIL,40眼)、B组(DRIL≤500 μm,52眼)和C组(DRIL>500 μm,40眼)。所有患者均接受康柏西普玻璃体腔注射治疗(每月1次,共3次),检测指标包括最佳矫正视力(BCVA,转换为LogMAR值记录)、黄斑中心视网膜厚度(CMT)、DRIL长度。比较3组患者基线资料、各时间点LogMAR视力变化、B/C两组DRIL长度动态变化。采用Spearman秩相关分析治疗前DRIL长度与各时间点LogMAR视力的相关性。采用多元线性回归分析影响抗VEGF治疗后视力恢复的因素。绘制受试者工作特征(ROC)曲线分析治疗前DRIL长度对治疗后6个月视力恢复的预测价值。结果:CMT随DRIL严重程度递增,A组(170.44±14.60) μm显著低于B组(342.60±46.28) μm,B组显著低于C组(380.45±52.57) μm,差异均有统计学意义(F=293.180,P<0.05)。治疗后1、2、3、6个月,A组LogMAR视力分别为0.56±0.16、0.46±0.12、0.38±0.15、0.18±0.10,均显著优于B组0.60±0.20、0.50±0.15、0.44±0.18、0.30±0.12和C组0.66±0.22、0.55±0.18、0.50±0.16、0.42±0.14,且B组显著优于C组,差异均有统计学意义(F组间=19.433,P<0.001)。治疗后6个月,B、C组DRIL长度均较治疗前显著缩短(F时点=1 849.396,P<0.001);其中B组由(380.60±30.61) μm 降至(102.33±12.69) μm,C 组由(546.87±38.64) μm降至(187.64±16.33) μm。Spearman相关分析显示,治疗前DRIL长度与患者治疗前及治疗后1、2、3、6个月的LogMAR视力均呈显著正相关(r=0.629、0.640、0.606、0.567、0.632,均P<0.001)。多元线性回归分析证实,较长的DRIL长度(β=0.860,95%CI:0.119~0.205)是抗VEGF治疗后视力恢复不佳的独立影响因素(均P<0.001)。ROC曲线分析显示,治疗前DRIL长度预测治疗后6个月视力预后的曲线下面积为0.781(95%CI:0.702~0.859),最佳截断值为352.9 μm,灵敏度为95.5%,特异度为52.3%。结论:治疗前DRIL是影响DME患者抗VEGF治疗后视力预后的重要影响因素,将其纳入治疗前常规OCT检查,有助于临床预后判断及个体化治疗策略制定。

Objective: To investigate the effect of disorganization of the retinal inner layers (DRIL) on visual recovery in patients with diabetes macular edema (DME) after anti-vascular endothelial growth factor (VEGF) treatment. Methods: A prospective cohort study design was used, 132 patients with monocular DME who visited Tianjin Eye Hospital from March 2022 to April 2023 (a total of 132 eyes) were consecutively included, with only 1 eye selected from each patient. According to the pre-treatment optical coherence tomography (OCT) measurement of DRIL length, patients were divided into three groups: group A (40 eyes without DRIL), group B (52 eyes with DRIL≤500 μm), and group C(40 eyes with DRIL>500 μm). All patients received intravitreal injection therapy with Conbercept (once a month, a total of three times), and the detection indicators included best corrected visual acuity (BCVA, converted to LogMAR value recording), macular center retinal thickness (CMT), and DRIL length. The baseline data of three groups of patients, changes in LogMAR visual acuity at each time point, and dynamic changes in DRIL length between groups B and C were compared. Spearman rank correlation analysis was used to investigate the correlation between DRIL length before treatment and LogMAR visual acuity at each time point. Multiple linear regression analysis was used to identify factors affecting visual recovery after anti VEGF treatment. Receiver operating characteristic (ROC) curves were plotted to analyze the predictive value of DRIL length before treatment on visual prognosis at 6 months after treatment. Results: CMT increased with the severity of DRIL, with group A (170.44±14.60) μm significantly lower than group B (342.60±46.28) μm, and group B significantly lower than group C (380.45±52.57) μm, with statistical significant differences (F=293.180, P<0.05). At 1, 2, 3, and 6 months after treatment, the LogMAR visual acuity of group A was 0.56±0.16, 0.46±0.12, 0.38±0.15, and 0.18±0.10, respectively, all significantly better than group B 0.60±0.20, 0.50±0.15, 0.44±0.18, 0.30±0.12, and group C 0.66±0.22, 0.55±0.18, 0.50±0.16, and 0.42±0.14, with group B significantly better than group C, and differences were statistically significant (Fgroup=19.433, P<0.001). After 6 months of treatment, the length of DRIL in groups B and C was significantly shortened compared to before treatment (Ftime point=1 849.396, P<0.001). Among them, group B decreased from (380.60±30.61) μm to (102.33±12.69) μm, and group C decreased from (546.87±38.64) μm to(187.64±16.33) μm. Spearman correlation analysis showed that the length of DRIL before treatment was significantly positively correlated with the LogMAR visual acuity of patients before treatment and at 1,2,3, and 6 months after treatment (r=0.629, 0.640, 0.606, 0.567, 0.632, all P<0.001). Multiple linear regression analysis confirmed that longer DRIL length(β=0.860, 95% CI: 0.119-0.205) was an independent factor affecting poor visual recovery after anti VEGF treatment(P<0.001). ROC curve analysis showed that the area under the curve of pre treatment DRIL length predicting 6-month visual prognosis after treatment was 0.781 (95% CI: 0.702-0.859), with an optimal cutoff value of 352.9 μm, sensitivity of 95.5%, and specificity of 52.3%. Conclusion: Pre-treatment DRIL is an important factor affecting the visual prognosis of DME patients after anti VEGF treatment. Including it in routine OCT examination before treatment can help in clinical prognosis judgment and personalized treatment strategy formulation.
