Obvious asymmetry of the cup‐disc ratio in the 2 eyes of an individual is regarded as a strong sign of glaucoma, which is useful in the early diagnosis. However, the size of the cup is proportional to the size of the disc, and consequently unequal discs will have unequal cup‐disc ratios. Three cases of ocular hypertension are presented to show an asymmetric cupping which in all probability is due to a congenital asymmetry of the discs, and not caused by glaucomatous damage. This possibility must be considered when evaluating patients with ocular hypertension.
