Evaluation of Higher Order Aberrations in Children With Unilateral Anisometropic Amblyopia

Abstract

OBJECTIVES:To quantify and analyse the higher order aberrations occurring in unilateral anisometropic Amblyopic eyes in our hospital. METHODS: An ORK WAVEFRONT ANALYZER -COAS version 1.43.2 Hartmann-Shack aberrometer was used to measure the ocular monochromatic aberrations. Amblyopic children comprising of only anisometric amblyopia were considered. RESULT: A total of 38 Anisometropic Amblyopes among the 63 Unilateral Amblyopic Children between 5-12 yrs. were studied. The arithmetic mean values for RMS of Total HOA in the AMBLYOPIC EYE and NORMAL EYE in ANISOMETROPIC MYOPIC AMBLYOPIA were 0.097 and 0.071 respectively. This difference was statistically significant (p=0.044).The arithmetic mean values for COMA (3,-1) and TREFOIL (3,-3) were statistically significant. CONCLUSION: This study indicates that among the types of unilateral anisometropic myopic amblyopia there was statistically significant relation in RMS of Total HOA, COMA (3,-1), TREFOIL (3,-3).
