Summary
The purpose of this explorative study, targeting subjects with advanced binocular glaucomatous visual field loss, is: (i) to identify the perimetric / psychophysical method, that is most closely correlated with an individually assessed quality of life (QoL) score, using a validated questionnaire (NEI-VFQ 25), (ii) to determine, whether gaze-related (exploratory eye movements) or visual field-related (eyes steadily fixating) OR attention-related parameters are better for the characterization of the visual capacities that are necessary for activities of daily living (ADL), as represented (iia) by a standardized visual search task and (iib) by an on-road car driving feasibility study. Further this study is intended to introduce and analyse a novel diagnostic method for recording and evaluating exploratory eye movements (gaze-related perimetry) in a clinical setting. A similar procedure has recently been introduced by Murray et al. However, their set-up is based on a video monitor and, therefore, restricted to the central visual field (eccentricity \< 25°) and limited with regard to the dynamic range of the stimulus luminance. Since our new gaze-related perimetry is designed to be implemented in a conventional cupola perimeter, it should be widely available as a potent diagnostic tool, for screening purposes, or for clinical surveys by general ophthalmologists or clinical research groups.
