Feasibility Tests for Various Prism Configurations for Visual Field Loss
Sponsor: Massachusetts Eye and Ear Infirmary
Summary
The investigators will develop and test different configurations of high-power prisms to expand the field of vision of patients with visual field loss to assist them with obstacle detection when walking. The study will involve multiple visits (typically four) to Schepens Eye Research Institute for fitting and testing with the prism glasses. The overall objective is to determine best designs and fitting parameters for implementation in prism devices for future clinical trials.
