A novel computerized visual acuity test was developed and tested on both healthy persons and patients with ocular conditions. Visual acuity outcomes of the computerized test will be compared to the Early Treatment Diabetic Retinopathy Study (ETDRS) in measures of reproducibility, accuracy and numbers of questions.
