Behavior disorders in children with significant refractive errors.

PURPOSE: To evaluate the frequency of behavioral disorders in children with significant refractive error and to compare the results with those of emmetropic children.

METHODS: In this prospective, comparative study from January to September 2013, refractive errors of all 5-12-year-old children who referred to a general eye clinic were recorded. A validated Persian version of the Rutter A scale was filled out by the parents for the evaluation of the child's behavioral disorders. The Rutter A scale scores of children with significant refractive error were compared with those of emmetropic eyes. Student t test, Chi square test, and Fisher's exact test were used for analysis. Differences with a P value less than 0.05 were considered significant.

RESULTS: One hundred eighty-three patients, including 101 patients with significant refractive error and 82 emmetropic subjects, were studied. Overall, 44 patients (24%) had behavioral disorders, according to the Rutter A scale scores. Thirty patients (29.7%) with significant refractive error and 14 emmetropic subjects (16.9%) had behavioral disorders (P = 0.043). The prevalence of behavioral disorders were 37.5% in hyperopia, 35.7% in hyperopia-astigmatism, 21.4% in simple astigmatism, 16.7% in myopia-astigmatism, and 14.3% in myopia. Compared with emmetropic subjects, the prevalence of behavioral disorders was statistically significantly higher only in patients with hyperopia and hyperopia-astigmatism (P = 0.019 and P = 0.040).

CONCLUSION: The prevalence of behavioral disorders is higher in children with hyperopia and hyperopia-astigmatism.
