Objective:

To determine the binocular function in patients with refractive amblyopia.

Method:

Cross-sectional study in patients between 5 and 18 years old with refractive amblyopia treated for the first time in the pediatric ophthalmology and strabismus consultation of the Instituto Cubano de Oftalmología Ramón Pando Ferrer.

Results:

No significant correlation was found between the depth of amblyopia and the magnitude of anisometropia in the right eye (p = 0.217) or in the left eye (p = −0.130), and neither between the magnitude of anisometropia and stereopsis (p = 0.260). Patients with isoametropic amblyopia reached a subnormal stereopsis >100" in 53.3%.

Conclusions:

There is no association between the magnitude of anisometropia and the depth of amblyopia, fusion and stereopsis. In most patients with refractive amblyopia, stereopsis is deteriorated, thus affecting binocular function.
