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

متن کاملOptic disc size and optic nerve damage in normal pressure glaucoma.
BACKGROUND Recent reports indicate that eyes with normal pressure glaucoma have larger optic discs than eyes with primary open angle glaucoma or normal eyes. This study was performed to find whether, in normal pressure glaucoma, a large disc is associated with more optic nerve damage than a small disc. METHODS Colour optic disc photographs of 74 patients with normal pressure glaucoma were ass...
