PURPOSE To identify and characterize defects using the automated perimetry test in patients with primary congenital glaucoma. METHODS Automated visual fields and charts of 81 eyes (48 patients) with congenital glaucoma were retrospectively analyzed, 15 being normal eyes (group N) and 66 eyes with primary congenital glaucoma (group G). Eyes of group G were grouped in eyes without perimetric ch...

OBJECTIVE To investigate practical fitness to drive mobility scooters, comparing visually impaired participants with healthy controls. DESIGN Between-subjects design. SUBJECTS Forty-six visually impaired (13 with very low visual acuity, 10 with low visual acuity, 11 with peripheral field defects, 12 with multiple visual impairment) and 35 normal-sighted controls. METHODS Participants comp...

A method to quantify different glaucomatous visual field defects is presented. Three visual field indices are calculated: the short-term fluctuation, the mean defect, and the corrected loss variation. The method was applied to visual fields tested with program JO on the Octopus automated perimeter. The indices of 130 glaucoma suspects and 50 glaucoma patients were compared with 100 normal contr...

BACKGROUND Progressive visual field defects, such as age-related macular degeneration and glaucoma, prevent normal stimulation of visual cortex. We investigated whether in the case of visual field defects, concentrations of metabolites such as N-acetylaspartate (NAA), a marker for degenerative processes, are reduced in the occipital brain region. METHODOLOGY/PRINCIPAL FINDINGS Participants kn...

PURPOSE To compare the prevalence of visual field loss, the sensitivity distribution, and the size and depth of glaucomatous visual field defects using the standard full threshold (FT) and the Swedish interactive threshold algorithm (SITA) standard (SS) procedures in patients with early or suspected glaucoma. METHODS Automated perimetry findings were retrospectively evaluated in 53 patients (...
