Randomized crossover clinical trial of real and sham peripheral prism glasses for hemianopia.

ABSTRACT:

Importance

There is a major lack of randomized controlled clinical trials evaluating the efficacy of prismatic treatments for hemianopia. Evidence for their effectiveness is mostly based on anecdotal case reports and open-label evaluations without a control condition.

Objective

To evaluate the efficacy of real relative to sham peripheral prism glasses for patients with complete homonymous hemianopia.

Design, setting, and participants

Double-masked, randomized crossover trial at 13 study sites, including the Peli laboratory at Schepens Eye Research Institute, 11 vision rehabilitation clinics in the United States, and 1 in the United Kingdom.
