Since the distribution of the retinal nerve fiber layer (RNFL) is not regular, this study was performed to evaluate the normal regional variation in its ophthalmoscopic appearance. Wide-angle red-free photographs of the RNFL and color stereo optic disc slides of 195 normal eyes of 119 subjects were morphometrically examined. The RNFL was most visible in the temporal inferior sector, with the neuroretinal rim being correspondingly broadest (P < 0.001) and the diameter of the corresponding retinal artery the widest; these parameters were found to diminish appreciably in the temporal superior sector, the nasal superior sector, and the nasal inferior sector in this order. The visibility of the RNFL in a particular region therefore correlates positively with the rim width and retinal artery caliber in that region, the RNFL being most detectable in the temporal inferior part of the fundus. This may be important in the evaluation of eyes with optic nerve damage.
由于视网膜神经纤维层（RNFL）的分布不规则，本研究旨在评估其检眼镜外观的正常区域差异。对119名受试者的195只正常眼睛的RNFL广角无赤光照片和彩色立体视盘幻灯片进行了形态测量检查。RNFL在颞下象限最明显，相应的神经视网膜边缘最宽（P < 0.001），相应视网膜动脉的直径最宽；这些参数在颞上象限、鼻上象限和鼻下象限依次明显减小。因此，特定区域RNFL的可见性与该区域的边缘宽度和视网膜动脉管径呈正相关，RNFL在眼底颞下部分最易检测到。这在评估视神经损伤的眼睛时可能很重要。
