Anxiety in visual field testing
British Journal of Ophthalmology, 2015To determine if Humphrey visual field (HVF) testing induces anxiety and how anxiety relates to visual field parameters of reliability and severity.A prospective cohort study at a university affiliated private ophthalmic practice.137 consecutive age-matched and gender-matched patients with glaucoma undergoing either HVF testing only (n=102) or ...

Visualizing the Results of Field Testing
2010 IEEE 18th International Conference on Program Comprehension, 2010Field testing of software is necessary to find potential user problems before market deployment. The large number of users involved in field testing along with the variety of problems reported by them increases the complexity of managing the field testing process.

Visual Function Tests: Visual Fields
2022Visual field tests, also known as perimetry tests, are used to assess progression of ophthalmic diseases such as retinitis pigmentosa (RP) by monitoring changes in a patient's visual field (VF). VF loss corresponds to damage at any point in the visual pathway, including the retina, such as in RP. Damage to different parts of this pathway corresponds to

Clinically, we usually carry out the monocular visual field test on the two eyes separately so that a comparison between them can be conducted. Sometimes, a binocular visual field test may be performed in situations such as tests for drivers. The fixation status of the tested eye should be emphasized repeatedly, whatever the test type.

Reliability of Simultaneous Visual Field Testing
Ophthalmology, 2012To 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.

Visualizing the structure of field testing problems
2009 IEEE International Conference on Software Maintenance, 2009Field testing of a software application prior to general release is an important and essential quality assurance step. Field testing helps identify unforeseen problems. Extensive field testing leads to the reporting of a large number of problems which often overwhelm the allocated resources.

Effectiveness of testing visual fields by confrontation
The Lancet, 2001Many tests are used to examine visual fields by confrontation, but such methods have not been thoroughly compared with an accepted reference standard. The choice of test might affect the identification of subtle defects in the visual field. We prospectively compared seven confrontation field tests with full-threshold automated static perimetry among ...
