Abstract
Background: Amblyopia is a disorder characterized by a decrease in the best-corrected visual
acuity in one or both eyes with no clear structural anomalies or ocular pathology.
There are three primary types of amblyopia: anisometropic, strabismic, and sensory
deprivation amblyopia. Anisometropic amblyopia occurs in children having a difference
in refractive error between the two eyes and occurs in the more ametropic eye. Furthermore,
there is a strong association of anisometropia with strabismus. Aim: The study aimed to investigate the association between age, sex, laterality, and
type of refractive error on the depth of anisometropic amblyopia. Settings and Design:
This was a retrospective (observational) study. Data were analyzed using IBM SPSS
23.0 software. Materials and Methods: One hundred and nine patient's files with anisometropic amblyopia were investigated,
who were followed in a pediatric eye clinic in Sohail Elatrash's eye hospital Benghazi,
Libya, between January 2008 and December 2018. Results: There is no effect of the type of gender on the depth amblyopia with P = 0.57. Furthermore,
there is no difference in the predominance of amblyopia between the right and left
eye (P = 0.93). Age is correlated in a positive manner with the depth of amblyopia
(P = 0.035). Conclusions: in our study, eye laterality and gender had no effect on
the depth of anisometropic amblyopia. The age and the smallest amount of astigmatism
difference between both eyes had a direct proportion on the depth of anisometropic
amblyopia.
