About this study

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Identification of the perimetric / psychophysical method, that is most closely correlated with an individually assessed quality of life (QoL) score

    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)

    Measured: 2 years

Secondary outcomes (1)
  1. 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)

    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

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Homonymous Hemianopia, run by University Hospital Tuebingen at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identification of the perimetric / psychophysical method, that is most closely correlated with an individually assessed quality of life (QoL) score (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01372332, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2014; AzTrials last refreshed its copy on 6 Nov 2026.
