Change of Refractive Error in Patients with Refractive Accommodative Esotropia

Purpose: To evaluate the degree and change in refractive error and the relation of refractive error, the angle of deviation and amblyopia in patient with refractive accommodative esotropia. Methods: Children with refractive accommodative esotropia were retrospectively included in the study. The factor studied were sex, age at the first visit, ocular alignment, refractive error and amblyopia. Results: The average age at the first visit was 4.01±1.86 years. And, the average angle of esodeviation was 22.23±13.74PD for the near and 21.51±12.01PD for the distant. The average manifest and cycloplegic refraction measured at patient`s first visit were +2.35±2.87D and +4.87±1.77D respectively. The difference between cycloplegic and manifest refraction decreased gradually. After 3 years, the average manifest and cycloplegic refraction were +3.42±1.80PD and +4.33±1.77D. The refractive error didn`t significantly affect the degree of esodeviation (r=0.051). Twenty-three of patients were amblyopia. The refraction of amblyopic and non amblyopic patient was +5.07±1.85D and +4.50±2.47D, respectively. However, this difference was not statistically significant. Conclusions: Mean cycloplegic refraction decreased significantly over a 3-year period. After full correction with glasses, the difference between cycloplegic and manifest refraction decreased. The refractive error was not associated with the degree of deviation anlge, amblyopia occurrence and treatment success.
