Abstract

Visual field measurement has long been considered the definitive test to distinguish glaucoma from ocular hypertension. However, recent clinical and histological studies^{1, 2} have shown that a large fraction of the optic nerve can be destroyed before visual field defects become apparent. Since glaucoma is a treatable disease, this finding underscores the need to develop more sensitive tests of glaucomatous optic nerve damage.
