PURPOSE: Anisometropia is one of the main causes of amblyopia. This study was conducted to investigate the association between the depth of amblyopia and the magnitude of anisometropia.
METHODS: A retrospective record review was conducted at the Nepal Eye Hospital between July 2006 and June 2011. Those children included in this study were aged ≤13 years and diagnosed with unilateral anisometropic amblyopia, no strabismus and ocular pathology. Associations between the depth of amblyopia and the age and/or gender of the subjects, the laterality of the amblyopic eyes, the type and magnitude of refractive error of amblyopic eyes, and the magnitude of anisometropia were statistically analyzed.
RESULTS: Out of the 189 children with unilateral anisometropic amblyopia (mean age 9.1 ± 2.8 years), 59% were boys. Amblyopia was more commonly found in left eye (p < 0.001). The most common type of refractive error was astigmatism (61%). The depth of amblyopia was not associated with the gender (p = 0.864) or age (p = 0.341) of the subjects or the laterality of the eyes (p = 0.159), but it was associated with the type (p = 0.049) and magnitude (p = 0.013) of refractive error of the amblyopic eye and the magnitude of anisometropia (p = 0.002).
CONCLUSION: Nepalese anisometropic amblyopic children were presented late to hospital. The depth of amblyopia was highly associated with the type and magnitude of refractive error of the amblyopic eye and the magnitude of anisometropia. So, basic vision screening programs may help to find out the anisometropic children and reefer them to the hospital for timely management of anisometropic amblyopia if present.
