About this study

Official title: Alternative Home Training Possibilities for Glaucoma Patients

The aim of the trial is to investigate the possibilities of improving visual impairments with eye training exercises (eye-yoga) in a total of 40 patients with glaucoma who have not previously been treated within a similar training program. 20 patients will be instructed how to do eye yoga to be performed dails for 4 weeks (max 30 min/day). As a control group of 20 patients will be instructed to read for 30 min/day for 4 weeks.

The following outcome measures will be investigated: High Resolution Perimetry, Humphrey Perimetry, Visual Acuity Test, Contrast Sensitivity Test, Microsaccades measurements, Intraocular Pressure Measurement, Electroencephalogram (EEG), Blood Pressure and Pulse Measurement and Dynamic Vessel Analysis (DVA - the blood supply in the eye (especially vascular dysregulation) .

Furthermore, factors that could influence response variability and the effectiveness of treatment will be analysed: (i) the role of mental stress (or stress resilience) and (ii) the influence of personality traits and quality of life.

The study is intended to further validate this home training program (eye yoga) for the treatment of visual impairment in glaucoma.

Read the detailed description

The aim of eye yoga is to improve microsaccade impairments in patient with primary open angle glaucoma. We will study how this affects visual performance and the physiology of the eye and brain

What is being measured

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

  1. Visual field size determined by perimetry measurements

    Changes of the visual field's size, evaluated by static perimetry and high resolution perimetry measurements

    Measured: 4 weeks

  2. Microsaccade measurements

    Changes in the deviation of eye movements when visual targets are followed, using a computerized test

    Measured: 4 weeks

Secondary outcomes (2)
  1. Blood circulation in the eye

    Changes of the diameter of blood vessels in the eye, measured by vessel analysis

    Measured: 4 weeks

  2. EEG connectivities

    Changes in alpha power using EEG recording (128 channels)

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Eye yoga and Passive Reading in people with Glaucoma and Eye Yoga, run by University of Magdeburg at 2 sites 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 4 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 9 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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

Contact Bernhard A Sabel, PhD (+491732540612, bernhard.sabel@med.ovgu.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual field size determined by perimetry measurements (time frame: 4 weeks). The study lists 2 primary outcomes in all. 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 NCT04037384, which also lists 3 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 9 Feb 2021.
