Clinical Features of Refractive Accommodative Esotropia According to Degree of Hypermetropia

ABSTRACT

PURPOSE: This study examined differences in clinical patterns according to the hyperopia level in refractive-accommodative esotropia patients. METHODS: Ninety-four refractive-accommodative esotropia patients were divided into 3 groups according to hyperopia level group 1, > or = +1.00D and or = +3.00D and or = +5.00D. The following factors were analyzed retrospectively the initial corrective visual acuity, the final corrective visual acuity, the angle of esotropia with or without hyperopic correction, the recovery time to orthophoria after hyperopic correction, the change in hyperopia level, and the frequency of amblyopia. RESULTS: The angles of esotropia without hyperopic correction in groups 1, 2 and 3 were 18.4+/-7.3PD, 22.9+/-8.5PD, and 25.7+/-10.4PD, respectively. The angle of esotropia was found to be significantly greater in the group with the higher level of hyperopia (P=0.01). The monthly change in hyperopia in groups 1, 2 and 3 was 0.018+/-0.02D, 0.028+/-0.03D and 0.043+/-0.03D. The change was greater in the group with the higher level of hyperopia (P=0.009). CONCLUSIONS: In refractive-accommodative esotropia patients, the more the hyperopia without correction increases, the more the angle of esotropia without correction increases, and the larger the reduction of hyperopia after correction becomes.
