摘      要：●AIM:To develop a novel approach called the Autoacuity Tester,and to evaluate its validity,especially the sensitivity and specificity for detecting amblyopia.●METHODS:Children aged from 3 to 12 y(n=552)were enrolled in the *** validity of the Autoacuity Tester was evaluated by comparing it to the Tumbling E Early Treatment Diabetic Retinopathy Study(ETDRS)acuity chart for school age children,and Lea Symbols and Teller acuity card(TAC)for preschool *** repeatability was assessed by coefficient of repeatability(COR).The sensitivity and specificity for detecting amblyopia were calculated.●RESULTS:The mean difference(95%limits of agreement)between the Autoacuity Tester and the ETDRS tests were-0.03(-0.24,0.19)logMAR for the school age *** preschool children,the mean difference was 0.04(-0.14,0.21)logMAR between the Autoacuity Tester and the TAC and 0.00(-0.17,0.18)logMAR between the Autoacuity Tester and the Lea *** the school age group,the COR was 0.20 logMAR for the Autoacuity Tester and 0.18 logMAR for the *** the preschool group,the COR was 0.13 logMAR for the Autoacuity Tester and 0.21 logMAR for *** Autoacuity Tester(88%)is more sensitive than TAC(72%)in detecting amblyopia(P=0.04),while had similar specificity(92%vs 90%,P=0.20).●CONCLUSION:The Autoacuity Tester provides a reliable alternative for assessing visual acuity,and offers advantage of higher testability and repeatability for preschool children.
