Rapid Assessment of Neurovisual Integrity Using Multiple Rarebits – Corrected Proof

Objective: Rapid assessments of vision commonly rely on visual acuity testing alone. Although well suited for uncovering optical defects, visual acuity tests may fail to detect dysfunction of the neural substrate. There is a need for a rapid companion test sensitive to neural damage.Design: Evaluation of diagnostic tests.Participants and Controls: Forty-seven patients with optic nerve or visual pathway lesions of low to moderate severities and 30 normal subjects.Methods: A new computer-based quick test of neurovisual integrity was developed using segmented digits defined by rarebits, that is, receptive field-size bright dots briefly presented on a dark background.Main Outcome Measures: The test (Read more...)
