Abstract
The early diagnosis of different refractive errors and
other predisposing factors of ambylopia can be achieved in
verbal and non verbal child by variable methods which suitable
for different age groups. This diagnostic techniques play role in
determining the method of treatment.
Traditional therapy for anisometropia includes refractive
correction with spectacles or contact lenses. Spectacle
correction of significant anisometropia produces aniseikonia.
Aniseikonia of more than 5% to 6% (typically present with 3.00
or more diopter of anisometropia) cannot be readily fused.
An occasional child will experience diplopia due to the
aniseikonia. Thus, glasses for moderate to severe anisometropia
are commonly not well tolerated. Spectacles for anisometropia
of more than 2.00 to 3.00 diopter are also cosmetically
problematic because of the differential magnification or
minification effect of the hyperopic or myopic lens,
respectively. Parents and children often complain of a
noticeable size difference in the appearance of the eyes through
such spectacles.
