Egbusim VC, Duru CC, Anyatonwu OP, et al. Effect of age and gender on the vertical cup-to-disc ratio in a normotensive population. Afr Vision Eye Health. 2024;83(1), a880. https://doi.org/10.4102/aveh.v83i1.880C.

The evaluation of the optic disc is an important clinical practice among eyecare practitioners. Inter-observer variability makes it difficult to establish a clear conclusion regarding the estimation of the cup-to-disc ratio (CDR), especially in the context of glaucoma.<b> </b>This study aimed to determine the effect of age and gender on cup-to-disc ratio in normotensive population and estimate the mean CDR of individuals of African descent.视盘（optic disc）评估是眼科从业者临床工作中的一项重要常规操作。观察者间差异会导致杯盘比（cup-to-disc ratio, CDR）的估算难以形成明确结论，在青光眼（glaucoma）相关临床场景中该问题尤为突出。本研究旨在明确年龄与性别对正常眼压人群杯盘比的影响，并估算非洲裔个体的平均杯盘比。
