To investigate the characteristics of cystic retinal tufts (CRTs) with 55° widefield spectral-domain optical coherence tomography.
This was a retrospective study. All subjects underwent a complete ocular examination, ultra-widefield (UWF) pseudocolor fundus photography and Spectral domain optical coherence tomography (SD-OCT) with a 55° widefield lens. The SD-OCT characteristics were analyzed in subjects with CRT.
Twenty-six eyes of 25 subjects were scanned and 29 CRTs were analyzed for SD-OCT characteristics. On SD-OCT images, the CRTs exhibited hyperreflective irregular elevated lesions with internal hyporeflective cystoid cavities. Normal layers of the neuroepithelium could not be distinguished. The mean diameter of CRTs was 1022 microns (range, 117-3711 microns; standard deviation, 815 microns). There was vitreoretinal traction at the apex of CRTs. Among them, retinal tears in 24.14% (7/29), suspected retinal tears in 27.59% (8/29), and shallow neuroepithelium detachment in 31.03% (9/29).
The widefield SD-OCT imaging can provide detailed cross-sectional anatomic information of CRT and may guide clinical treatment.
利用 55°广角谱域光学相干断层扫描（SD-OCT）研究囊性视网膜丛（CRTs）的特征。
这是一项回顾性研究。所有受试者均接受全面眼部检查、超广角（UWF）假彩色眼底照相和 55°广角镜头的谱域光学相干断层扫描（SD-OCT）。对 CRT 患者的 SD-OCT 特征进行分析。
共扫描了 25 名患者的 26 只眼，对 29 个 CRT 进行了 SD-OCT 特征分析。在 SD-OCT 图像上，CRTs 表现为高反射性不规则隆起病变，其内有低反射性囊性腔。无法区分神经上皮的正常层。CRTs 的平均直径为 1022 微米（范围 117-3711 微米；标准差 815 微米）。CRTs 顶端有玻璃体视网膜牵引。其中，视网膜裂孔占 24.14%（7/29），疑似视网膜裂孔占 27.59%（8/29），浅神经上皮脱离占 31.03%（9/29）。
广角 SD-OCT 成像可以提供 CRT 的详细横断面解剖信息，可能有助于指导临床治疗。
