Accommodative ability in patients with strabismic amblyopia at concomitant strabismus

Abstract

Aim. To study the state of the accommodative ability of amblyopia before and after treatment.
 Materials and methods. One hundred patients (158 eyes) with friendly alternating and monolateral strabismus were examined. The control group consisted of 10 healthy individuals (20 eyes) with emmetropia: the average age of patients under 3 years of age was 2.4 0.15 years, from 3 years to 7 years, 4.8 0.07 years, and above 7 years, 8.3 0.4 years. The vast majority of patients (84 people, 126 eyes) had hyperopic astigmatism, and 16 patients (32 eyes) had a high degree of hyperopia. Twenty-eight patients (40 eyes), 48 patients (84 eyes), and 20 patients (26 eyes) had amblyopia of the 1st, 2nd, and 3rd degrees, respectively. Along with generally accepted methods for examining eyes, the OAA volume and ZAA were determined as the absolute accommodation margin by the proximetric method (AKA-0.1) before and after hardware treatment to relax and stimulate the ciliary muscle.
 Results. The results after treatment revealed a 1.52-fold increase in OAA to 14.4 0.23 D; 13.5 0.10 D; 13.1 0.41 D; and ZAA and a significant 2-fold increase in visual acuity (P 0.001).
 Conclusion. A criterion for the effectiveness of hardware treatment for dysbinocular amblyopia is an increase in OAA and ZAA, accompanied by a 2-fold increase in distance visual acuity (P 0.001).
