摘要:
The variability of optic nerve parameters obtained with versions 3.4 and 3.5 of the Topcon IMAGEnet computer stereo analysis system was studied. The consistency of horizontal cup-to-disc ratio, vertical cup-to-disc ratio, cup volume, neuroretinal rim area, neuroretinal rim-to-disc area, and the percentage of poorly correlated conjugate points (bad points) on the stereo pair was compared. The updated computer program for stereo analysis provides a significantly more accurate means to assess both the cup volume and the neuroretinal rim area as evidenced by the smaller number of bad points.
