Optic disc pallor was recorded in 53 eyes of 53 patients by means of global analysis with a video-ophthalmograph (Rodenstock Disk Analyzer) and computerized boundary analysis. The coefficients of correlation between the values obtained with the Rodenstock Disk Analyzer and those obtained with boundary analysis were r = 0.24 (p = 0.08) at the 0.29 cutoff level, r = 0.39 (p = 0.004) at the 0.39 level and r = 0.46 (p = 0.0005) at the 0.50 level. Although the correlation was significant, the correlation coefficients were not high. The Rodenstock Disk Analyzer uses global analysis, which does not take into account the spatial relationship of the pallor on the disc, whereas boundary analysis is sensitive to spatial relationship, which may account for the poor correlation.
通过使用视频检眼镜(罗敦司得视盘分析仪)进行整体分析和计算机化边界分析,记录了53例患者53只眼中的视盘苍白情况。在0.29的截断水平下,罗敦司得视盘分析仪获得的值与边界分析获得的值之间的相关系数为r = 0.24(p = 0.08);在0.39水平下,相关系数为r = 0.39(p = 0.004);在0.50水平下,相关系数为r = 0.46(p = 0.0005)。尽管相关性显著,但相关系数并不高。罗敦司得视盘分析仪采用的是整体分析,没有考虑视盘上苍白区域的空间关系,而边界分析对空间关系敏感,这可能是相关性较差的原因。
