Official title
Comparative Efficacy of Saccadic and Biofeedback Training in Homonymous Hemianopia: A Comprehensive Eye Movement Pilot Study
Overview
This pilot study aims to understand how eye movements change in people with vision loss from stroke after completing one of two types of training. The study will look at how eye movements and reading performance change after training. Researchers will compare the results of two groups: one group will complete five clinical training sessions using an eye-tracking machine for 30 minutes each, while the other group will do at-home reading exercises for 20 minutes a day, 5 days a week, for 6 weeks. The goal is to see if there is a difference in performance between the two types of training.
Interventions
- Behavioral Biofeedback Fixation Training
This training type involves the use of microperimetry. Microperimetry is a visual field test that incorporates perimetry and retinal imaging and is a standard ophthalmic clinical technology. It allows for direct observation of the fundus, but uses an eye-tracking system to compensate for involuntary eye movements. A program designed to train patients to direct and hold their gaze at an eccentric location programmed by the controller will be used. When the participant directs their gaze towards t - Behavioral Saccadic Reading Training
Participants will be assigned to participate in an at-home reading program. The reading exercises consist of worksheets with letter and number combinations of increasing complexity and font sizes. They are intended to increase accuracy in identifying letters and numbers. Worksheets will initially be dispensed with larger font type and spacing and be graded at weekly intervals towards regular, newspaper-size print and spacing over the course of training.
