With repeat visual field testing, most patients find their ability to maintain a steady straight-ahead gaze improves, thus improving the reliability of the results. The following are common testing times for visual fields in both eyes: Amsler grid: a few minutes Confrontation visual field: a few...

Visual field testing checks how well you can see in all areas of your vision, including your side (peripheral) and central vision. It's used to find and monitor vision problems, especially those that might not show up in a regular eye exam.
Visual field testing is a crucial component of the neurologic, and more specifically the ophthalmologic, examination. A lesion or disruption may occur anywhere in the pathway from the striate cortex of the occipital lobe to the retina, causing a specific visual field defect. Identification of that...
Purpose To determine the comparability of test results obtained using two versions of commercially available frequency doubling technology (FDT) software for visual field testing. Methods One hundred glaucoma patients underwent duplicate N-30 threshold FDT visual field examinations of one eye; one test ...
C H A P T E R 56 Visual Field Testing I. INTRODUCTION Abnormalities of peripheral vision are called visual field defects. These defects, many of which can be detected at the bedside, provide important clues to the diagnosis of lesions throughout the visual pathways—the ret- ina, optic...
Here, we proposed a bidirectional gated recurrent unit (Bi-GRU) algorithm to predict visual field loss. In total, 5413 eyes from 3321 patients were included in the training set, whereas 1272 eyes from 1272 patients were included in the test set. Data from five consecutive visual field ...
1. Confrontation visual field test An optometrist typically uses confrontation visual field testing to determine if further field testing is required. In confrontation testing, one eye is covered and the other focuses on a target object. The optometrist then asks the patient to describe what is see...
