Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Visual acuity
visual acuity was displayed in decimal units in the computerized program and by the number of letters in the early treatment diabetic retinopathy study chart (ETDRS).
through study completion, an average of 1 year
Study Arms (2)
Healthy
healthy volunteers with no known ocular condition
Patients
Subjects with diseases of the eye or the orbit
Interventions
Each subject underwent visual acuity assessments using the Early Treatment Diabetic Retinopathy Study (ETDRS) chart and the computerized program
