Dear Editor,

I have read with interest the article on the profile of amblyopia by Menon et al .[1] Published literature on the clinical profile of amblyopia[2],[3] including the ongoing Pediatric Eye Disease Investigator Group trials[4] have, by convention, classified the sub-types of amblyopia as anisometropic, strabismic, mixed/combined anisometropia with strabismus and form deprivation. However, Menon et al[1] in their classification of amblyopia, have added two further sub-types such as ametropic and meridional amblyopia, bringing to our notice, that 18.44% (12.88+5.56 %) of patients had subnormal visual acuity without having anisometropia, strabismus or form deprivation. Some of these patients could also be having some contributing non-ocular pathology, requiring a pediatric neurological reference and laboratory investigations. These patients, by definition, are then not amblyopes. The remaining patients in this group would be those having an uncorrected refractive error and should improve with time, only with refractive adaptation i.e. without any specific amblyopia treatment. These are, therefore, not true amblyopes. However, due to lack of any other nomenclature, they get clubbed with amblyopes.
