We studied the change in the optic disk topography during spontaneous pressure reduction in laser-induced primate glaucoma (7 eyes, follow-up of 20 weeks) using computerized image analysis (vertical and horizontal cup-to-disk ratios CDR(V), CDR(H); neuroretinal rim area/disk area; cup volume/disk area). A significant correlation was found between the percent pressure reduction and the percent reversal in each disk parameter. There was no significant difference in the percent reversal between CDR(V) and CDR(H). These results suggest that reversal of cupping may depend on the percent pressure reduction, and may occur symmetrically in primate glaucoma.
我们使用计算机图像分析技术（垂直和水平杯盘比CDR(V)、CDR(H)；神经视网膜边缘面积/盘面积；杯体积/盘面积），研究了激光诱导的灵长类青光眼（7只眼，随访20周）在眼压自发降低过程中视盘地形图的变化。发现眼压降低百分比与每个视盘参数的逆转百分比之间存在显著相关性。CDR(V)和CDR(H)之间的逆转百分比没有显著差异。这些结果表明，杯状凹陷的逆转可能取决于眼压降低的百分比，并且在灵长类青光眼患者中可能对称发生。
