More Information
Summary:Systems, apparatus, and methods are provided for quantifying inter-ocular suppression in binocular vision impairment. The systems, apparatus, and methods may include a stimulus presentation device and a controller which present different stimuli to each eye of a patient. The stimuli can include letters, numbers, or shapes which are arranged in rows, and columns with a stimulus presented to each eye in a location corresponding a stimulus presented to the other eye. The combined contrast of corresponding stimuli equals a predetermined value, and this contrast can be adjusted with each iteration of stimuli presented. This adjustment can be based upon the patient's reports of what is seen and adjustments made by an algorithm executed by the controller. Suppression can thus be determined in terms of visual field location and quantified.
