目的：对比玻璃体切割术(pars plana vitrectomy, PPV)联合或不联合注射地塞米松玻璃体内植入剂(dexamethasone intraveal implant, DEX)治疗特发性黄斑前膜(idiopathic macular epiretinal membrane, IMEM)的临床疗效。
方法： 采用回顾性研究设计，收集2022年1月—2023年6月于惠州市中心人民医院就诊，被诊断为IMEM(Gass 2期)并行PPV联合phaco+IOL植入的患者49例(49只眼)。根据其治疗方案分为非联合注射DEX组(25例共25只眼)及联合注射DEX组(24例共24只眼)。记录所有患者术前术后的最佳矫正视力(best corrected visual acuity, BCVA)、黄斑中心凹视网膜厚度(central macular thickness, CMT)、平均神经节细胞层(ganglion cell layer, GCL)厚度，椭圆体带(ellipsoidal zone, EZ)完整性。使用OCTA测量视网膜浅层毛细血管层(superficial capillary plexus, SCP)、中心区域血管密度(vessel densities, VDs)及中心凹无血管区(foveal avascular zone, FAZ)面积。使用非接触性眼压计测量患者眼压。随访至术后6个月，记录上述指标，其中BCVA及CMT随访至1年。使用SPSS 29.0软件进行数据的统计分析(独立样本t检验、Mann-Whitney U检验、Pearson χ2检验等)。使用重复测量方差检验分析各项指标的时间差异及交互差异性。采用线性回归分析CMT、平均GCL厚度、EZ完整性、VDs、FAZ面积及联合注射DEX与BCVA的相关性。
结果：本研究两组间性别、年龄、眼压及术前各项指标差异均无统计学意义(P>0.05)。两种术式均能改善黄斑区结构、功能及微循环障碍，术后的BCVA在两组患者中均较术前有所改善，且持续至术后6个月，CMT的变化趋势同BCVA有高度一致性，而平均GCL厚度于术后3个月时开始恢复，而SCP中心凹VDs及FAZ面积于术后6个月时才有明显恢复，两种术式术后以上各指标均具有时间差异及交互差异性(P≤0.015)，且6个月内联合注射DEX组表现更佳(P=0.036)。相较于非联合注射DEX组，只有联合注射DEX组在术后6个月时，EZ完整性的改善具有统计学意义(P=0.009)。但随访至1年时，两组之间BCVA及CMT差异均无统计学意义(P=0.079)。术后6个月内BCVA的改善与术后6个月的CMT、平均GCL厚度、SCP中心凹VDs、FAZ面积的改善及EZ完整性及是否注射DEX与术后6个月内BCVA的改善均有相关性。随访期间两组患者均未发生眼内炎、玻璃体积血、视网膜脱离等眼部或全身严重并发症。
结论：微创玻璃体切割术联合玻璃体内注射DEX治疗相较于非联合注射DEX治疗组在6个月内疗效更佳。联合单次注射DEX治疗方案与非联合注射DEX治疗方案相比，在手术1年后对BCVA及CMT的改善无明显差异。

Objective: To analyze the efficacy and safety of minimally invasive vitrectomy (PPV) with or without intraoperative injection of dexamethasone intravitreal implant (DEX) for the treatment of Idiopathic Macular Epiretinal Membrane (IMEM), by comparing the relevant indicators.

Methods: A retrospective study design was used to collect 49 patients (49 eyes) who were diagnosed with IMEM (Gass2) and underwent surgical treatment(PPV+phaco+IOL implantation) at Huizhou Central People’s Hospital from January 2022 to June 2023. According to their treatment plan, they were divided into a non-combined injection DEX group (25 cases, 25 eyes) and a combined injection DEX group (24 cases,24 eyes). All patients underwent comprehensive optometry before and after surgery, and their best corrected visual acuity (BCVA) was recorded. Scan the central macular thickness (CMT) within 6x6mm of the macular area, while scanning the average ganglion cell layer (GCL) thickness. Record whether the elliptical zone (EZ) within 1x1mm of the macular area is complete and continuous. Use OCTA mode to scan the superficial capillary layer (SCP) of the retina within a range of 6x6mm, and record the measurements of vascular density (VDs) in the central area and the area of the foveal avascular zone (FAZ). Measure the patient's intraocular pressure using a non-contact tonometer. Follow up for 6 months and record the above indicators, with BCVA and CMT followed up for 1 year. Perform statistical analysis of data using SPSS 29.0 software (Independent sample t-test, Mann Whitney U-test and Pearson χ2-test). Use repeated measures ANOVA to analyze the time differences and interaction differences of various indicators. Linear regression analysis was used to examine the correlation between CMT, mean GCL thickness, EZ integrity, VDs, FAZ area, and combined injection of DEX with BCVA.

Results: There were no statistically significant differences in gender, age, intraocular pressure, and preoperative indicators between the two groups (P>0.05). Both surgical methods can improve the structure, function, and microcirculation disorders in the macular area. The postoperative BCVA in both groups of patients improved compared to before, and persisted until 6 months after surgery. The trend of CMT changes was highly consistent with BCVA, while the average GCL thickness began to recover at 3 months after surgery. The SCP fovea VDs and FAZ area did not show significant recovery until 6 months after surgery. Both surgical methods showed time differences and interaction differences in the above indicators after surgery (P=0.015), and the combined injection of DEX group performed better within 6 months (P=0.036). Compared to the non combined injection of DEX group, only the combined injection of DEX group showed statistically significant improvement in EZ integrity at 6 months after surgery (P=0.009). However, at 1 year of follow-up, there was no statistically significant difference in BCVA and CMT between the two groups (P≥0.079). The improvement of BCVA within 6 months after surgery is correlated with the improvement of CMT, average GCL thickness, SCP fovea VDs, FAZ area, EZ integrity, and injection of DEX within 6 months after surgery. During this study, no serious ocular or systemic complications such as endophthalmitis, vitreous hemorrhage, or retinal detachment occurred in either group of patients at each follow-up time point.
Conclusions: The efficacy of PPV combined with intravitreal injection of DEX is better within 6 months compared to the non-combined injection of DEX treatment group. There was no significant difference in the improvement of BCVA and CMT after one year of surgery between the combined single injection DEX treatment regimen and the non-combined injection DEX treatment regimen.
