Evaluation of the Friedmann Visual Field Analyser.
Visual fields were assessed in 320 eyes of 169 patients, using the Friedmann Visual Field Analyzer (F.V.F.A.) and the Oculus perimeter. The F.V.F.A. was found to be a rapid indicator of both the presence, the location and the density of scotomata. Because some defects were missed by the F.V.F.A. it should be used in combination with some other technique to search for early defects, particularly...
متن کاملComparison of contrast sensitivity, visual acuity, and Humphrey visual field testing in patients with glaucoma.
BACKGROUND Despite their normal or near-normal Snellen visual acuity, patients with glaucoma often complain of "poor" vision. OBJECTIVE To investigate the relationship between large-letter contrast sensitivity, high-contrast visual acuity, and visual field defects in patients with glaucoma who have 20/40 or better visual acuity. DESIGN Prospective, cross-sectional case series. PATIENTS AN...
متن کاملVisual field examination using a video projector: comparison with Humphrey perimeter
PURPOSE To present a method of visual field examination using a video projector. Also, we compare our results with those of a Humphrey perimeter, which is accepted as standard in automated perimetry. MATERIALS AND METHODS Software implementing a full-threshold 4-2-step staircase algorithm for the central 30-2 of the visual field (76 points) has been developed and tested in nine eyes of seven ...
متن کاملHumphrey visual field analysis, visual field defects, and ophthalmic findings in patients with macro pituitary adenoma.
OBJECTIVE To evaluate the Humphrey visual field parameters in patients with pituitary adenoma and classify the visual field defects in this patient group. METHODS Forty primary pituitary adenoma patients underwent neuro-ophthalmological examination and Humphrey Perimetry 30-2 visual field test at Baskent University, Departments of Ophthalmology, and Neurosurgery, between 2003 and 2005. Global...
متن کاملVisual Field Testing with Head-Mounted Perimeter ‘imo’
PURPOSE We developed a new portable head-mounted perimeter, "imo", which performs visual field (VF) testing under flexible conditions without a dark room. Besides the monocular eye test, imo can present a test target randomly to either eye without occlusion (a binocular random single eye test). The performance of imo was evaluated. METHODS Using full HD transmissive LCD and high intensity LED...
