QUANTIFICATION OF INTER-OCULAR SUPPRESSION IN BINOCULAR VISION IMPAIRMENT

摘要

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.

主权项

1. A system for quantifying suppression in binocular vision of a patient, the system comprising:
a stimuli presentation device configured to present stimuli comprising a distinct stimulus for each eye of the patient; and a controller, operably connected to the stimuli presentation device, the controller comprising: a computer comprising an interface configured to accept input from a clinician, a patient, or both; an adaptive algorithm executed on the computer, the adaptive algorithm configured to accept a report describing what the patient sees when presented with the stimuli and calculate adjustments to the stimuli to be presented in the next iteration of stimuli; and a stimulus generating component configured to provide the next iteration of stimuli to the patient via the stimuli presentation device.
