This study aimed to detect corneal conditions presenting with linear images on white light confocal microscopy and to analyze their distinguishing characteristics.
In 1996 and 1997, 153 eyes of 110 patients with various corneal conditions were examined. In vivo examination of the cornea was performed by using a white-light tandem scanning confocal microscope. Images were captured by using a video camera and stored on S-VHS video tapes. In this retrospective study, patient charts and confocal microscopic video records were reviewed. Conditions with linear images were looked for, and the images were analyzed and compared.
The only structures presenting as linear images on confocal microscopy in normal subjects consisted of corneal nerves. The following pathologic conditions also had linear images on confocal microscopy: corneal vascularization, mycotic keratitis, lattice corneal dystrophy, and posterior polymorphous dystrophy. Each condition could be identified based on its reflectivity, delineation, size, branching pattern, and location in the cornea.
Different corneal conditions present with linear images on confocal microscopy. Correct identification is critical to avoid misdiagnosis.
本研究旨在检测在白光共聚焦显微镜下呈现线性图像的角膜病变情况，并分析其鉴别特征。
1996年和1997年，对110例患有各种角膜病变的患者的153只眼睛进行了检查。使用白光串联扫描共聚焦显微镜对角膜进行活体检查。通过摄像机采集图像并存储在S - VHS录像带上。在这项回顾性研究中，查阅了患者病历和共聚焦显微镜视频记录。寻找呈现线性图像的病变情况，并对图像进行分析和比较。
正常受试者在共聚焦显微镜下呈现为线性图像的唯一结构是角膜神经。以下病理状况在共聚焦显微镜下也有线性图像：角膜血管化、真菌性角膜炎、格子状角膜营养不良和后弹力层多形性营养不良。每种状况都可根据其反射率、轮廓、大小、分支模式以及在角膜中的位置来识别。
不同的角膜病变在共聚焦显微镜下呈现线性图像。正确识别对于避免误诊至关重要。
