@entity1 @entity940 @entity2516 @entity3467 @entity9340 @entity1714
INTRODUCTION: For many years, attempts have been made to find an easy, efficient and inexpensive method to screen @entity1 for amblyogenic @entity2516 . Wave-front analysis is a new way to determine the refractive state of the eye from a distance. This technique could be a useful tool for @entity1 screening. PURPOSE: The purpose of the study was the evaluation of the efficacy of a commercially available wave-front analyzing autorefractometer (SureSight, software version 2.0, Welch Allyn, Skaneateles Falls, NY 13153, U.S.A.) in detecting amblyogenic @entity2516 in @entity1 with and without cycloplegia. METHODS: 256 eyes (-28.25 D to +7.88 D spherical equivalent) of 128 @entity1 (1-81 years) were examined with the wave-front autorefractometer under cycloplegia. Prior to this investigation, 108 eyes (-21.38 D to 75 D) of 54 of these @entity1 (1-76 years) were refracted without cycloplegia. The readings of the wave-front autorefractometer were compared with the results of retinoscopy under cycloplegia. RESULTS: Without cycloplegia, the sensitivity in detecting any amblyogenic @entity2516 such as @entity9340 , @entity940 , @entity1714 or @entity3467 was 94%, while the specificity was 63%. Following cycloplegia, the sensitivity decreased to 87% and the specificity increased to 80%. CONCLUSION: Wave-front analyzing refractometry is highly applicable for @entity1 screening. At the present state of development, the efficacy in detecting amblyogenic @entity2516 is similar to that of other screening techniques and instruments that operate from distance. Cycloplegia enhances the sensitivity in detecting @entity3467 and decreases the sensitivity in detecting @entity940 .
