To analyse the autofluoresence (AF) properties of pingueculae and compare the size of AF with the extent of the visible lesion.
Forty eyes of 23 patients with pingueculae were included in the study. AF images were obtained using an HRA2 confocal scanning laser ophthalmoscope; anterior segment photographies were obtained using TRC-50IX, IMAGEnet 2000 Digital Imaging System. The AF characteristics of pingueculae were analysed. The extent of visible lesion in anterior segment photography and AF image was compared.
AF images revealed well-defined hyper-autofluorescence in the area of pinguecula, which was greater than the extent of visible pinguecula in the slit-lamp examination, in 40 of 56 lesions (71.4%). In none of the eyes was the hyperautofluorescent area smaller than the extent of visible lesion.
Pingueculae display hyperautofluorescence in AF imaging. The real size of pingueculae may be estimated by its AF characteristics, which is mostly larger than the visible lesion.
分析睑裂斑的自发荧光（AF）特性，并比较AF大小与可见病变范围。
本研究纳入了23例患有睑裂斑患者的40只眼。使用HRA2共焦扫描激光眼科显微镜获取AF图像；使用TRC-50IX、IMAGEnet 2000数字成像系统获取眼前节照片。分析睑裂斑的AF特征。比较眼前节照片和AF图像中可见病变的范围。
AF图像显示睑裂斑区域有明确的高自发荧光，在56个病变中的40个（71.4%）中，其大于裂隙灯检查中可见睑裂斑的范围。在所有眼中，高自发荧光区域均不小于可见病变的范围。
睑裂斑在AF成像中表现为高自发荧光。可通过其AF特征估计睑裂斑的实际大小，其大多大于可见病变。
