SYSTEM AND METHOD FOR EVALUATING OCULAR HEALTH

摘要

A method for adaptively determining a model of visual performance of a test subject comprising the step of exposing a test subject to a plurality of trials. Each trial comprises the steps of identifying the stimulus pattern to test, generating a stimulus pattern on a display, determining whether the stimulus pattern generated an OKR, updating the model to incorporate the OKR results, and determining whether the updated model is acceptable. The trials can be iteratively repeated until the model for visual performance is acceptable.

1. A method for determining a visual performance metric of a test subject, the method comprising the steps of:
estimating, by the processor, a model for at least one visual performance metric; identifying, by the processor, a stimulus pattern based, at least in part, on the estimated model, wherein the stimulus pattern comprises sinusoidally-modulated contrast gratings; generating, on a display, the stimulus pattern to present the stimulus pattern to the test subject; determining, by the processor, an Optokinetic Reflex (OKR) result indicating whether the stimulus pattern induced OKR in the test subject; updating, by the processor, the estimated model to incorporate the OKR result; and determining, by the processor, whether the updated model is acceptable.
