目的：介绍一种用激光共聚焦扫描检眼镜（SLO）对筛板孔进行形态计量分析的方法。方法：用SLO从视网膜表面到视盘底部以+0.25屈光度的增量连续获取16幅图像。采用20度视场的633 nm He-Ne激光器。在麦金塔软件的帮助下，对每个部分的图像进行了处理和组合。结果：生理性拔火罐的眼孔呈均匀圆形或近圆形，而原发性开角型青光眼的眼孔常被压缩。结论：该技术可对视神经头青光眼病变的进展进行体内网膜内膜表面形态测定，对视神经头青光眼病变的进展有一定的指导意义。(C) 1999年日本眼科学会。
Purpose: To describe a method for making morphometric analysis of the pores in the lamina cribrosa with a confocal scanning laser ophthalmoscope (SLO).Methods: Sixteen consecutive images were acquired with an SLO from the retinal surface to the bottom of the optic disc in +0.25-diopter increments. An He-Ne laser (633 nm) with a 20 degrees field of view was used. The images from each section were processed and combined with the aid of Macintosh software.Results: Eyes with physiological cupping showed uniformly round or nearly round pores, whereas eyes with primary open-angle glaucoma frequently had compressed pores.Conclusions: In vivo morphometry of the surface of the internal lamina cribrosa can be performed by this technique, which should be useful for evaluating the progression of glaucomatous changes of the optic nerve head.
