Identification of glaucomatous visual field defects from examination of monocular photographs of the optic disc.

Abstract

A study was carried out of monocular disc photographs from 33 eyes for which the visual fields on both static profile and kinetic perimetry has been performed. Physical signs looked for at the optic disc included thinning of the neuroretinal rim, angulation of retinal vessels, extension of laminar dots, undercutting of the neuroretinal rim, and absence and pallor of the neuroretinal rim. These signs together proved more accurate than kinetic Goldmann perimetry in identifying the presence of glaucomatous visual field defect. Of these signs angulation of the retinal vessels was the one most consistently present.
