Asymmetrical cupping of the optic disc was found in 5.6% of normal individuals, in 30% of a group with ocular hypertension without field defect, and in 36% of those with established chronic open-angle glaucoma and field loss. Disc asymmetry was also instrumental in leading to the diagnosis of subacute angle-closure glaucoma and of chronic vascular insufficiency of the optic nerve. The search for disc asymmetry is an essential part of glaucoma screening.
