To evaluate spectral-domain optical coherence tomography (OCT) findings based on preferential hyperacuity perimeter (PHP) in patients after idiopathic epiretinal membrane surgery.
Forty eyes of 40 patients undergoing surgery for idiopathic epiretinal membrane were included in the study. The best-corrected visual acuity, PHP, Amsler grid test, and OCT were assessed 3 months after surgery.
Patients were classified based on the defect of hyperacuity by PHP, as follows: hyperacuity defect (n = 18 eyes) and hyperacuity intact (n = 22 eyes). There was no difference in age, gender, duration of symptoms, and visual acuity. The average macular thickness and inner nuclear layer thickness in the hyperacuity defect group was thicker than the hyperacuity intact group (P = 0.041 and P = 0.045, respectively). A disrupted photoreceptor layer was more common in the hyperacuity defect group compared with the hyperacuity intact group (P = 0.001).
With regard to metamorphopsia, a hyperacuity defect after epiretinal membrane surgery was associated with inner nuclear layer edema and photoreceptor disarrangement.
评估特发性视网膜前膜手术后患者基于超视力优先周边(PHP)的光谱域光相干断层扫描(OCT)结果。
本研究纳入了 40 例(40 只眼)接受特发性视网膜前膜手术的患者。术后 3 个月评估最佳矫正视力、PHP、Amsler 网格测试和 OCT。
根据 PHP 的超视力缺损对患者进行分类,如下:超视力缺损(n=18 只眼)和超视力完整(n=22 只眼)。两组在年龄、性别、症状持续时间和视力方面无差异。超视力缺损组的黄斑厚度和内核层厚度的平均值高于超视力完整组(P=0.041 和 P=0.045)。超视力缺损组比超视力完整组更常见光感受器层中断(P=0.001)。
就变形性而言,视网膜前膜手术后的超视力缺损与内核层水肿和光感受器排列紊乱有关。
