Training of Eye Movements in Glaucoma

Not Applicable
Conditions
Eye Yoga
Glaucoma
Registration Number
NCT04037384
Lead Sponsor
University of Magdeburg
Brief Summary

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.

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
