SINCE 1996, the American Academy of Ophthalmology's Preferred Practice Pattern (PPP) for primary open-angle glaucoma¹ has defined glaucoma as an acquired optic neuropathy with either visual field or optic nerve manifestations. Buttressed by mounting evidence that optic nerve damage generally precedes detectable visual field damage,^1-3 the PPP defines early glaucoma as having no visual field defect on routine threshold perimetry. The presence of any characteristic visual field loss defines the severity as at least moderate in nature. This, in turn, generates important clinical questions.

First, what role do the various imaging technologies have in relation to stereophotographs and clinical examinations in detecting those who already have moderate glaucoma (associated with visual field loss) in 2001? In this edition of the ARCHIVES, Zangwill et al⁴ report a comparison of several methods of evaluation of the optic nerve for their ability to differentiate between patients with proven (reliable and reproducible) mild or . . .
