Twenty-five patients age 3 to 9 years old (mean; 6.3 years) with anisohypermetropia of 2 diopters or greater and amblyopia without manifest strabismus were studied. They did not have there cylinder level exceed 2.0 diopters. All patients wore appropriate spectacles and received occlusion therapy. The visual prognosis of anisohypermetropic amblyopia was analyzed on the basis of corneal topography and four other factors. Twenty-three patients (92%) had a visual acuity improvement of better than 0.8. The visual prognosis was unrelated to patient age, the degree of anisometropia and refractive diopters of the amblyopic eye. The prognosis was not as good in patients whose initial visual acuity was under 0.2. The surface regularity index (SRI) and surface asymmetry index (SAI) using corneal topography were adapted for quantitative descriptor measurement. The prognosis was not as good when the SRI and SAI of the amblyopic eye were higher than in the other eye. Based on the results of this study I recommend that amblyopia in risky patients be treated effectively. It is therefore suggested that corneal topography can apply clinically for a factor of decision of visual prognosis of anisohypermetropic amblyopia.
