Research Article: Inter-Rater Reliability of EyeSpy Mobile for Pediatric Visual Acuity Assessments by Parent Volunteers
Introduction:
Measurements of visual acuity, the ability of the visual system to discern spatial resolution, have inherent test-to-test variability, even in the absence of true visual changes. Testing modifications designed to minimize test-to-test variability may improve testing accuracy. Eye chart design has evolved to improve standardization of visual acuity testing through the selection of letters with similar recognition difficulty, the display of equal numbers of letters per line, uniformity of letter spacing, and other…
