Equivalent Intrinsic Noise Sampling Efficiency and Contrast Sensitivity in Patients With Retinitis Pigmentosa

摘要

Purpose.To determine the relationships among equivalent intrinsic noise (Neq), sampling efficiency, and contrast sensitivity (CS) in patients with retinitis pigmentosa (RP), where Neq is an estimate of the amount of noise within the visual pathway and sampling efficiency represents the subject's ability to use stimulus information optimally.
