Automated perimeter for binocular suppression.
Scotomas associated with suppression amblyopia can appear or enlarge under binocular conditions. A device was designed to present an independent LED stimulus array to each eye while both eyes fixate together through beam splitters on a common background pattern. A computer-controlled field screening examination was designed to automatically plot suppression scotomas under binocular conditions.
