Abstract：
OBJECTIVE: We aimed to quantitatively evaluate metamorphopsia pre- and postoperatively in patients with idiopathic epiretinal membrane(iERM) using M-CHARTS™ and to evaluate the relationship between morphological changes in retinal layers on optical coherence tomography (OCT) and metamorphopsia scores.
METHODS: This prospective study included 42 patients followed in Akdeniz University Hospital Ophthalmology Clinic diagnosed with iERM by fundus examination and OCT between 2020-2022. Detailed ophthalmologic findings, visual acuities, metamorphopsia scores, and OCT parameters of all patients were recorded. The relationship between pre- and postoperative visual acuity, metamorphopsia scores and OCT parameters was investigated. Changes in OCT parameters were compared by evaluating patients with stable or increasing metamorphopsia scores as one group (group1) and patients with decreasing metamorphopsia scores as the other group (group 2).
RESULTS: In \"group 2\", preoperative Ganglion Cell Layer+Inner Plexiform Layer (Central) (GCL+IPL (C)) was significantly (P: 0.028) higher than in \"group 1\".
CONCLUSIONS: A statistically significant preoperative thickness difference in the OCT parameters of the GCL+IPL (C) layer was associated with the quantitative metamorphopsia complaints of the patients. The thickness of the preoperative GCL+IPL (C) layer can be considered an important indicator of symptoms of metamorphopsia determining functional success after surgery.

摘要：
目的：我们旨在使用M-CHARTS™定量评估特发性视网膜前膜（iERM）患者术前和术后的变形，并评估光学相干断层扫描（OCT）上视网膜层的形态变化与变形评分之间的关系。
方法：这项前瞻性研究包括在2020年至2022年期间在阿克德尼兹大学医院眼科诊所通过眼底检查和OCT诊断为iERM的42例患者。详细的眼科发现，视力,蜕变得分,记录所有患者的OCT参数。术前、术后视力的关系,研究了变形性评分和OCT参数。通过评估一组（组1）和另一组（组2）的变态反应评分降低的患者，比较OCT参数的变化。
结果：在\"组2\"中，术前神经节细胞层+内丛状层(中央)(GCL+IPL(C))明显高于“第1组”(P:0.028)。
结论：术前GCL+IPL(C)层OCT参数的厚度差异具有统计学意义，与患者的定量变形症状有关。术前GCL+IPL(C)层的厚度可以被认为是决定手术后功能成功的变形症状的重要指标。
