在眼底出现视神经萎缩征象之前和之后，测量了一系列具有各种前视通路非血管性病变的病例的视网膜小动脉直径的眼底照片。当视网膜中央动脉不能直接测量时，设计了一种简单的方法来可靠地估计视网膜中央动脉的直径：这允许在不同的眼睛之间进行比较，而不考虑小动脉分支模式的个体差异。萎缩始终与视网膜中央动脉口径减少有关，发生全视神经萎缩的眼睛平均为24%，发生半视神经萎缩的眼睛平均为17%。正常对照的最大侧差为8%。
Measurements were made on fundus photographs of the diameters of retinal arterioles in a series of cases with various nonvascular lesions of the anterior visual pathways, before and after the development of fundus signs of optic atrophy. A simple method was devised for reliable estimation of the diameter of the central retinal artery whenever this vessel could not be measured directly: this allowed comparisons to be made between different eyes, irrespective of individual variations in arteriolar branching patterns. Atrophy was consistently associated with a decrease in central retinal artery caliber, averaging 24% in eyes developing total optic atrophy, and 17% in eyes with hemi-atrophy. Normal controls showed a maximum side difference of 8%.
