A reliable bedside test for screening of visual field defects is a valuable tool in the examination of patients with a putative disease affecting the sensory visual pathways. Conventional methods such as Donders' confrontation method, counting fingers ...
Optical Coherence Tomography (OCT) is a powerful instrument for helping clinicians detect and monitor glaucoma. The aim of this study was to provide a detailed mapping of the relationships between visual field (VF) sensitivities and measures of retinal s

Conventional methods such as Donders' confrontation method, counting fingers in the visual field periphery, ot two-hand confro...
4d–f). We used the dendritic arborization in the medulla for each pathway to estimate the area of a direct pathway or an indirect pathway. We overlaid them into a single putative receptive field (Fig. 4c,d), which we further analysed to obtain the outline of the visual field of the ...
Methods for testing visual field vary. Some simple screening tests can be done in a few minutes during a regular vision check-up. Other tests are more complicated and comprehensive computerized tests. Confrontation Visual Field Test During this test, the healthcare provider or technician sits at ...

Is It Useful to Perform Visual Field Screening for Glaucoma? Modern Methods of Checking the Visual Field and Their Relevance Testing Strategies for The Glaucoma Patient Is There Still a Place for Kinetic Testing Using The Goldmann Perimeter? Sidebar 23.2 Another perspective on the need for Go...
Another important aspect of the field of view is that portion of the visual field seen by the macula, the central field of view. This portion of the retina, with a radius of approximately 30 degrees, is used for detail and color and is responsible for visual acuity. The retina is a spe...
It is important that the same technician performs the testing with a Goldmann perimeter from visit to visit to reduce the chances of variability in the field due to operator differences. The Amsler grid test may help identify central macular changes. It is occasionally useful as a screening test...
