To assess change over time in the optic disk and the associated change in visual field, we retrospectively reviewed perimetry results and optic disk photographs of adult patients treated for glaucoma. Three glaucoma specialists masked to the clinical course independently reviewed optic disk stereophotographs and visual fields taken before and after(More)
PURPOSE To investigate structural brain changes in patients with glaucoma. METHODS High-resolution T1-weighted anatomical brain magnetic resonance images (MRI) were collected in 15 patients with glaucoma of varying severity and in 15 age-, race-, and sex-matched controls. Exclusion criteria included neurological disease, another disorder which could(More)
The need for more sensitive tests for the early detection of compromised visual function in glaucoma is established by anatomic and psychophysical evidence of damage occurring to optic nerve fibers in eyes with normal visual fields. The results are reported of temporal frequency testing on 51 glaucoma suspects without visual field loss in either eye, 52(More)
PURPOSE Heterozygous optic atrophy type1 (OPA1) mutations are responsible for dominant optic atrophy, and the down regulation of OPA1 expression in patients with Leber hereditary optic neuropathy may imply that Opa1 protein levels in mitochondria play a role in other spontaneous optic neuropathies as well. Mitochondrial and metabolic abnormalities may put(More)
Examination of stereoscopic optic disc photographs allowed accurate prediction of glaucomatous and normal fields to be made in 82 and 95% of eyes respectively and for visual field loss to be correctly located in upper and lower half in 83 and 91% of cases respectively. Despite this high correlation the existence of false positive and fale negative(More)
OBJECTIVES To evaluate the relationship of a performance-based measure of visual functioning to clinical and subjective measures in glaucoma patients. DESIGN Cross-sectional survey of glaucoma patients. PARTICIPANTS Forty-three patients with primary open-angle glaucoma. METHODS Patients were evaluated using a novel performance-based measure, the(More)
The optic nerves of 34 eyes of 34 patients with low-tension glaucoma were compared with those of 41 eyes of 41 patients with high-tension glaucoma. Mean intraocular pressure in the low-tension group was 16.9 +/- 0.7 mm Hg (mean +/- SEM) compared with 31.7 +/- 0.8 mm Hg in the high-tension group. Mean total visual field loss was not significantly different(More)
BACKGROUND Vision loss from glaucoma has traditionally been described as loss of "peripheral vision." In this prospective study, we aimed to improve our clinical understanding of the visual symptoms caused by glaucoma by asking patients specific detailed questions about how they see. METHODS Patients who were clinically diagnosed with various types and(More)
