Abstract

Visual acuity (VA) is a traditional measure of central visual function, particularly the ability of the eye to perceive details. In a clinical setting, standardized charts are commonly used to quickly assess VA. Namely, the Early Treatment of Diabetic Retinopathy Study (ETDRS) VA test chart is the gold standard for VA testing in the clinical setting. This chapter outlines the standard procedures associated with measuring VA.

Keywords: Early Treatment of Diabetic Retinopathy Study (ETDRS); HOTV chart; VA testing; Visual acuity; Visual impairment.
