GlauCUTU: Virtual Reality Visual Field Test

2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021
This study proposed a virtual reality (VR) head-mounted visual field (VF) test system, or also known as the GlauCUTU VF test, for a reaction time (RT) perimetry with moving visual stimuli that progressively increase in intensity. The test entailed 24-2 VF protocol and was examined on 2 study groups, controls with normal fields and subjects with ...

Visual Field Testing

2012
• Glaucoma results in progressive visual field deterioration, and detecting changes or recording stability in the visual field is important in the management of glaucoma. • Visual field testing is a highly subjective and operator-dependent test. • In patients with glaucoma, the visual field is tested in monocular fashion.

Visual Fields: Visual Field Test Strategies

2009
The question can be answered in many ways. First of all, there are visual field devices used to perform automated static perimetry and those for manual kinetic perimetry. Automatedtests utilize computer programs to vary test speed, target size, and luminance.

Visual Field Testing With Red Targets

Archives of Ophthalmology, 1983
Ten patients with partial temporal visual field defects were examined with a modified tangent screen projection perimeter (Auto-Plot). Defects demonstrated with an isopter for chromatic recognition of a 3-mm red stimulus could always be reproduced with an isopter for achromatic recognition of a dim, 3-mm white stimulus.

SITA visual field testing in children

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2001
The Swedish Interactive Thresholding Algorithm (SITA) is a new testing strategy for the Humphrey perimeter. The standard SITA algorithm shortens test time in adults without increasing variability, but its usefulness for detecting field defects in children has not been investigated.We evaluated 92 standard SITA 24-2 visual fields of children, most of ...

Reliability of Simultaneous Visual Field Testing

Ophthalmology, 2012
To test for differences in reliability and performance between traditional, isolated perimetry and simultaneous testing with 2 patients in the same room.Comparative case series.A total of 471 eyes of 261 subjects.Consecutive patients undergoing Humphrey visual field (VF) testing in the Kellogg Eye Center glaucoma clinic were screened.

Objective Visual Field Testing

JAMA, 1963
THE VALUE OF visual field testing is well established in the fields of ophthalmology, neurology, neurosurgery, and internal medicine. The time-consuming nature of this subjective test, with its inherent inaccuracies in patients unable to cooperate fully, is familiar to most clinicians.

TESTING VISUAL FIELDS BY FLICKER FUSION

Archives of Neurology And Psychiatry, 1951
THE CRITICAL rate at which a flickering light of decreasing frequency is first perceived to flicker is the one test of visual function in which the light-adapted eye is more sensitive at the periphery of the retina than at its center. Previous investigators have agreed that flicker fusion fields are sensitive and "typical" in neurological lesions ...

Confrontation visual field testing: detecting gross visual field defects

International Journal of Ophthalmic Practice, 2011
Performing confrontation visual fields is a quick and relatively easy way of detecting gross visual field defects. It requires little or no special equipment and can be performed in practically any situation, including during domiciliary visits. The practitioner should be familiar with the types of confrontation visual field tests and their uses and ...
