Official Title: Assessment of Homonymous Visual Loss and Its Impact on Visual Exploration, Activities of Daily Living (ADL) and Quality of Life (QoL)

Brief Summary:

The purpose of this explorative study, targeting subjects with homonymous visual field loss, is threefold:

(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) parameters are better for the characterization of the visual capacities that are necessary for activities of daily living (ADL), as represented by (iia) a standardized visual search task ("supermarket special offer search task") (iib) by an on-road car driving pilot study.


Detailed Summary:
Sponsor: University Hospital Tuebingen

Current Primary Outcome: Identification of the perimetric / psychophysical method, that is most closely correlated with an individually assessed quality of life (QoL) score [ Time Frame: 2 years ]

Quality of life (QoL) is better correlated with the modified ESTERMAN score of the binocular semi-automated kinetic perimetry of the 90° visual field than with the number of affected test locations (local sensitivity < 10 dB) according to the binocular integrated visual field (IVF)


Original Primary Outcome: Same as current

Current Secondary Outcome: Exploration whether gaze-related or visual field-related parameters are better for the characterization of the visual capacities that are necessary for activities of daily living (ADL) [ Time Frame: 2 years ]

  1. Activities of daily living ("supermarket special offer search task"), are better correlated with the modified ESTERMAN score, based on the intact binocular gaze field than with the modified ESTERMAN score, based on the binocular semi-automated kinetic perimetry of the 90° visual field (90° SKP)
  2. Activities of daily living (driving performance) are better correlated with (the ESTERMAN score, based on) the intact binocular gaze field than with the UFOV risk score


Original Secondary Outcome: Same as current
