Abstract

Purpose: To assess the sensitivity and specificity of the "triple layer sign" (TLS) (retinal pigment epithelium (RPE), neovascular tissue, and Bruch's membrane) on structural optical coherence tomography (OCT) images for the diagnosis of treatment-naïve non-exudative type-1 macular neovascularization (NE-MNV) in age-related macular degeneration (AMD).

Design: Cross-sectional study.

Methods: Two masked retinal experts evaluated the presence of the TLS in eyes with NE-MNV and controls with an RPE elevation without exudation due to other causes than NE-MNV in AMD [e.g., medium-large drusen, cuticular drusen, basal laminar deposits (BlamD)].

Results: 130 eyes of 98 consecutive patients met the study criteria; 40 eyes of 40 patients satisfied the criteria for being included in the NE-MNV secondary to AMD group (27 females, 13 males, with a mean age of 73.8 ± 8.0 years), and 90 eyes of 58 patients met the criteria to be included in the control group (31 eyes were included in the medium-to-large drusen sub-group, 32 eyes in the cuticular drusen sub-group, and 27 eyes in the BlamD group. The TLS was observed in 39/40 patients with NE-MNV and 8/90 controls. The sensitivity and specificity of the TLS for the diagnosis of NE-MNV were 97% and 91%, respectively.

Conclusions: The TLS on OCT demonstrated high sensitivity and specificity values in detecting treatment-naive type 1 NE-MNV.

三层标志"：用于检测非渗出性黄斑新生血管的光学相干断层扫描特征。

目的：评估结构性光学相干断层扫描（OCT）图像上的 "三层征"（TLS）（视网膜色素上皮（RPE）、新生血管组织和布鲁氏膜）对年龄相关性黄斑变性（AMD）中治疗无效的非渗出性1型黄斑新生血管（NE-MNV）诊断的敏感性和特异性：设计：横断面研究：两名蒙面视网膜专家评估了NE-MNV患者眼球中是否存在TLS，以及除AMD中NE-MNV外，因其他原因（如中-大色素沉着、角化性色素沉着、基底层沉积（BlamD））导致RPE升高但无渗出的对照组眼球中是否存在TLS：98名连续患者的130只眼睛符合研究标准；40名患者的40只眼睛符合继发于AMD的NE-MNV组的标准（27名女性，13名男性，平均年龄为73.8 ± 8.0岁），58名患者的90只眼睛符合对照组的标准（31只眼睛被纳入中大型色素亚组，32只眼睛被纳入角质样色素亚组，27只眼睛被纳入BlamD组。在 39/40 例 NE-MNV 患者和 8/90 例对照组中观察到了 TLS。TLS诊断NE-MNV的敏感性和特异性分别为97%和91%：OCT上的TLS在检测未经治疗的1型NE-MNV方面显示出较高的灵敏度和特异性。

期刊介绍： Graefe''s Archive for Clinical and Experimental Ophthalmology is a distinguished international journal that presents original clinical reports and clini-cally relevant experimental studies. Founded in 1854 by Albrecht von Graefe to serve as a source of useful clinical information and a stimulus for discussion, the journal has published articles by leading ophthalmologists and vision research scientists for more than a century. With peer review by an international Editorial Board and prompt English-language publication, Graefe''s Archive provides rapid dissemination of clinical and clinically related experimental information.
