Abstract

PURPOSE

To determine the effects of optic disc size on vertical cup-disc ratio in subjects free of glaucoma and other optic nerve disease.

METHODS

Data were collected from 3654 people, 49 years of age of older, living in the Blue Mountains, west of Sydney (NSW, Australia). Examinations performed included subjective refraction and Zeiss colour stereo optic disc photographs. Eye and camera magnification effects were corrected.

RESULTS

Mean vertical disc diameter was 1.51 mm (95% confidence interval (CI) 1.504-1.516 mm) and the mean vertical cup-disc ratio was 0.43 (95% CI 0.425-0.435). Both parameters were distributed unimodally. The cup-disc ratio was strongly associated with disc diameter. Controlling for other variables, cup-disc ratio increased 0.270 (95% CI 0.250-0.290) per mm increase in disc diameter.

CONCLUSIONS

Vertical optic disc diameter and cup-disc ratio are distributed near normally in older Australians. Optic discs with larger vertical diameters have considerably greater vertical cup-disc ratios.

摘要

目的

确定在无青光眼及其他视神经疾病的受试者中，视盘大小对垂直杯盘比的影响。

方法

收集了来自澳大利亚新南威尔士州悉尼西部蓝山地区的3654名49岁及以上人群的数据。进行的检查包括主观验光和蔡司彩色立体视盘照片。校正了眼睛和相机的放大效果。

结果

平均垂直视盘直径为1.51毫米（95%置信区间（CI）1.504 - 1.516毫米），平均垂直杯盘比为0.43（95%CI 0.425 - 0.435）。两个参数均呈单峰分布。杯盘比与视盘直径密切相关。在控制其他变量的情况下，视盘直径每增加1毫米，杯盘比增加0.270（95%CI 0.250 - 0.290）。
