A free-floating vitreous cyst is a rare eye disease. This study aimed to find diagnostic imaging methods and imaging features for vitreous cysts.
This article presents a case report along with a literature review of published cases of vitreous cysts. The case report describes a highly myopic 60-year-old woman with a pigmented, free-floating vitreous cyst in her right eye. A search of the PubMed database using the keywords "vitreous cyst" was performed to identify other cases reported in the literature and to summarize the imaging methods used to diagnose and visualize vitreous cysts and the imaging features of vitreous cysts.
A thorough ophthalmic examination was performed in the present case, including slit-lamp photography, B-scan ultrasound, broad line fundus imaging, spectral-domain optical coherence tomography (SD-OCT), and ultra-wide field SS-OCT. The literature review revealed the imaging methods used in previously reported cases of vitreous cysts in which ultra-wide field SS-OCT has the advantages of wide scanning depth and high imaging clarity.
SS-OCT has an advantage over SD-OCT in providing intuitive morphological characteristic images for the diagnosis of posterior vitreous cysts. The comprehensive assessment of multimodal imaging examinations, including SS-OCT, is of significant value for the diagnosis and differential diagnosis of vitreous cysts.
游离性玻璃体囊肿是一种罕见的眼科疾病。本研究旨在寻找玻璃体囊肿的诊断性影像学方法及影像学特征。
本文呈现了一例病例报告，并对已发表的玻璃体囊肿病例进行了文献综述。该病例报告描述了一名60岁高度近视女性，其右眼有一个色素性、游离性玻璃体囊肿。使用关键词“玻璃体囊肿”在PubMed数据库中进行检索，以识别文献中报道的其他病例，并总结用于诊断和显示玻璃体囊肿的影像学方法以及玻璃体囊肿的影像学特征。
本病例进行了全面的眼科检查，包括裂隙灯照相、B超扫描、广域眼底成像、光谱域光学相干断层扫描（SD-OCT）和超广角SS-OCT。文献综述揭示了先前报道的玻璃体囊肿病例中所使用的影像学方法，其中超广角SS-OCT具有扫描深度广和成像清晰度高的优点。
在为诊断后部玻璃体囊肿提供直观的形态学特征图像方面，SS-OCT比SD-OCT更具优势。包括SS-OCT在内的多模态成像检查的综合评估对玻璃体囊肿的诊断和鉴别诊断具有重要价值。
