PURPOSE To determine diagnostic accuracy of kinetic visual field assessment by Octopus 900 perimetry compared with Goldmann perimetry. METHODS Prospective cross section evaluation of 40 control subjects with full visual fields and 50 patients with known visual field loss. Comparison of test duration and area measurement of isopters for Octopus 3, 5, and 10°/sec stimulus speeds. Comparison of ...

PURPOSE To evaluate and compare intra- and intertest variability components for both standard automated perimetry (SAP) and frequency-doubling technology (FDT) perimetry in a small group of normal individuals and patients with glaucoma. METHODS The method of constant stimuli (MOCS) was used to examine matched test locations with both SAP and FDT perimetry stimuli in a group of eight normal in...

PURPOSE To compare short-wavelength automated perimetry, frequency-doubling technology perimetry, and motion-automated perimetry, each of which assesses different aspects of visual function, in eyes with glaucomatous optic neuropathy and ocular hypertension. METHODS One hundred thirty-six eyes from 136 subjects were evaluated with all three tests as well as with standard automated perimetry. ...

Sparing or partial recovery of visual fields in hemianopic patients is frequently difficult to document. This is because when testing large field losses, the standard automated or manual visual field testing systems have limited fixation controls. Measured visual field recovery in these cases may not be real but instead may be due to an artifact such as scanning eye movement. This article illus...

OBJECTIVE To compare manual kinetic perimetry with tangent screen and Goldmann techniques and automated static perimetry with the Humphrey Field Analyzer in the detection and localization of occipital lobe lesions. DESIGN Prospective consecutive comparative case series. PARTICIPANTS Twelve patients with well-defined occipital lobe infarcts on magnetic resonance (MR) imaging were studied. ...

AIM To determine the sensitivity and specificity of entoptic perimetry for diagnosing diabetic retinopathy at all levels of severity. METHODS A prospective clinical study at the Shiley Eye Center, University of California, and San Diego. 30 patients with photographically documented diabetic retinopathy and 24 controls with a similar age distribution. Sensitivity and specificity of entoptic pe...
