I4e stimuli produced statistically significantly larger visual field areas when comparing HFA3 and Octopus 900 to Goldmann perimetry. The VFRC has processed more than 14,000 Humphrey and Goldmann visual field tests. Octopus perimetry continues to show greater defect size where there is more extensive visual field loss relating to the different strategies used by both perimeters. After requesting quantified visual field tests, the patient returns with a black and white printout with numbers (eg, Humphrey fields) or coloured lines on a sheet (eg, Goldmann fields). Humphrey field analyser (HFA), is a tool for measuring the human visual field, it is used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field.. Conclusion. The basic concepts of these two systems can be applied to other kinetic or automated systems. The strongest correlation was observed between inferior nasal regions. Relationship between optical coherence tomography sector peripapillary angioflow-density and Octopus visual field cluster mean defect values. Each of the mean threshold values at each point of the visual field was numbered and considered as a variable for the factor analysis. You can manage this and all other alerts in. I4e stimuli produced statistically significantly larger visual field areas when comparing HFA3 and Octopus 900 to Goldmann perimetry. Imagine you are assessing a patient with visual difficulties or optic disc swelling. Traquairs field of vision 7. It’s an automated, static perimeter (unlike Goldmann kinetic perimetry which requires a human operator, and uses a moving target). patterns of visual field loss Lauren R. Hepworth and Fiona J. Rowe* Abstract Background: Visual field loss occurs frequently in neurological conditions and perimetry is commonly requested for patients with suspected or known conditions. Conclusions: Visual field results were comparable for mild defects. Cookie Settings. Sixty per cent of the patients preferred Goldmann perimetry. 1 Values range from 100% (normal) to 0% (perimetrically blind). visual difficulties or optic disc swelling.

Perimetry programs which meet these criteria include the Humphrey 30-1, 30-2, 24-1, 24-2, SITA Fast, and SITA Standard Visual Field Tests, and the Octopus 30-1 and 30-2 Visual Field Tests. Here, we’ll only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests. Permission to republish any abstract or part of an abstract in any form must be obtained in writing from the ARVO Office prior to publication. The VFI is a staging index for the total amount of field loss. Brenton RS, Argus WA. A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumours or other neurological deficits. As the gold standard of perimetry, Humphrey ® Field Analyzer 3 (HFA3) is your trusted diagnostic partner. The Octopus perimeter, the Humphrey Field Analyzer, and Humphrey Matrix are a few of the available automated perimeters. Analyzer vs. Octopus. Methods: One hundred and thirty-four consecutive patients with open-angle glaucoma were prospectively selected. Therefore, it provides information regarding the location of any disease processes or lesion(s) throughout the visual pathway. Mean age was 60.66 ± 10.35 years. Visual Field Test Octopus Humphrey Visual Field Analyser Haag-Streit Holding, Slit Lamp is a 1000x500 PNG image with a transparent background. The Octopus 600 performs standard white-on-white threshold testing in just 2–4 minutes in the central visual field, and also offers the most commonly used static tests. HFA3 delivers the interactive analysis you need, when and where you need it. Introducing the 8th edition of the Visual Field Digest from Haag-Streit. With over 65,000 installed units worldwide, the HFA is the premier automated visual field analyzer. Our results are consistent with previous studies, in which the distribution of the visual field regions for the superior and inferior hemifields was reported to be asymmetric. Here, we’ll only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests. Automated static perimetry now constitutes the method used for the great majority of visual fields monitoring in the care of patients with glaucoma. Perimetry programs which meet these criteria include the Humphrey 30-1, 30-2, 24-1, 24-2, SITA Fast, and SITA Standard Visual Field Tests, and the Octopus 30-1 and 30-2 Visual Field Tests.
