Data collection for vertical cup-to-disc (VCDR) ratio study

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.
