Repetitive Training with Medical-Eye-Trainer (MET)

Device: Medical-Eye-Trainer (MET)

Interventions

Medical-Eye-Trainer (MET) DEVICE

In order to provide a high contrast, dynamic visual stimulus to the patients, we developed an app that allowed the patients to regularly train with this stimulus. The app runs on Android (version 4.2 or later). The display of the screen is divided into 4 rows. In each row, a pattern of black and white squares is moving in one direction. The directions in subsequent rows are opposite to each other. Through the movement in the opposite direction a changing pattern is achieved in vertical and horizontal extension, the pattern alternates between continuous beams and a checkered pattern. The speed of the display on the monitor is 2 cm per second. In a comfortable viewing distance (ca. 40 cm), this leads to an angular velocity of approximately 3°/sec.

• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

In the study, 11 patients were included. In five of those, both eyes were affected by AMD; in the six other patients, only one eye was affected. The age of the patients was 72 ± 14.7 years (mean ± standard deviation, range 44 - 86 years). Eight eyes had received a lutein therapy for more than 2 years, according to the Age-Related Eye Diseases Study (AREDS) study. In two eyes an anti-VEGF (vascular endothelial growth factor ) therapy had been performed before (3.5 and 4 years ago, respecitvely); and in one eye a photodynamic therapy (PDT) had been performed 9 years ago. All eyes had been affected by dry AMD for 3.5 years or more. The visual acuity had been unchanged for at least a year in all patients. None of the patients reported any previous occurrence of epilepsy.

You may qualify if:

• All eyes had been affected by dry AMD for 3.5 years or more

You may not qualify if:

• None
