Purpose: General reduction of differential light sensitivity in glaucoma is a controversial issue. Purely diffuse visual field loss is not a sign of glaucoma, but it has been postulated that the best parts m the visual field are always affected to some extent. We studied the best parts of the visual field in a material of glaucomatow visual fields. Methods: Humphrey 30-2 threshold tests from 19...

The topography of visual and somatosensory projections to the superior colliculus in the Syrian hamster was studied using electrophysiological techniques. The visual projection to the superficial layers of the colliculus is similar in general topography to that described for other rodents. The magnification of the visual field on the colliculus surface was greatest for nasal visual field. The m...

A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...

Peripheral vision plays an important role in human visual behavior. Performance in visual search and orientation tasks in general depends largely on peripherally detected information. Among the factors affecting peripheral visual performance are the size and shape of the effective visual field. Traditional theories of visual search work on the assumption of perfectly circular or elliptical visu...
