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 کاملOcular aberrations in the peripheral visual field.
We modified a commercial Hartmann-Shack aberrometer and used it to measure ocular aberrations twice at each of 38 points across the central 42 degrees horizontal x 32 degrees vertical visual fields of five young emmetropic subjects. Some Zernike aberration coefficients show coefficient field distributions that were similar to the field dependence predicted by Seidel theory (astigmatism, oblique...
متن کاملNormal visual field test results following glaucomatous visual field end points in the Ocular Hypertension Treatment Study.
OBJECTIVE To compare the occurrence of normal visual field (VF) test results following 2 vs 3 consecutive, abnormal, reliable test results in the Ocular Hypertension Treatment Study. METHODS The Ocular Hypertension Treatment Study is a prospective, multicenter follow-up study as part of a longitudinal randomized clinical trial. Sixty-four (68 eyes) of 1636 participants developed a VF primary ...
متن کاملAcquired color vision and visual field defects in patients with ocular hypertension and early glaucoma
PURPOSE To study acquired color vision and visual field defects in patients with ocular hypertension (OH) and early glaucoma. METHODS In a prospective study we evaluated 99 eyes of 56 patients with OH without visual field defects and no hereditary color deficiencies, followed up for 4 to 6 years (mean = 4.7 +/- 0.6 years). Color vision defects were studied using a special computer program for...
متن کاملDissociation of visual deficits in ocular hypertension.
Both acquired color vision deficiencies and abnormal pattern electroretinograms (PERGs) are observed in patients with ocular hypertension (OHT) as well as in patients with glaucoma. In the present study we determined the prevalence of both of these functional deficits in a large group of OHT patients (N = 130). Color vision was tested with the desaturated D-15 and a color confusion score was us...
