The Association Between Refraction, Ocular Biometry, and a Child's Behavior Assessed by Conners' Parental Rating Scale.

PURPOSE: To examine the association between refraction, ocular biometry and a child's behavioral disorder using the Conners' Parent Rating Scale.

MATERIALS AND

METHODS

This cohort study recruited 139 children aged 6-9 years old. Their legal guardians completed the Conners' Parent Rating Scale [the revised-long version (CPRS-R-L)], and the individual responses were entered into the software scoring program, resulting in 14 scores for behavioral disorders. Cycloplegic refraction and ocular biometry were performed. Correlation analyses among the 14 behavioral scores, refraction, and biometry were performed. The analyses were performed for three refractive groups: hyperopia, emmetropia, and myopia.

RESULTS

Children (N = 93) with mean age of 7.2 ± 1.2 y were included. Spherical equivalent (SE) of the refractive groups were +3.46±1.71 diopters (D), 0.61 ± 0.41 D and -1.76 ± 2.15 D (p < 0.0001). The CPRS-R-L subscale scores positively correlated with sphere, SE, and negatively correlated with cylinder. With the exception of oppositional behavioral subscale that had higher than mean score, 13 CPRS-R-L scores fell within the normal range, regardless of refraction. CPRS-R-L subscale scores negatively correlated with axial length. Axial length shorter than 22.5 mm had CPRS-R-L 95th percentile, some of which surpassed the normal range score of CPRS-R-L, and indicate the presence of ADHD concerns.

CONCLUSION

Refraction, astigmatism, and axial length were associated with Conners' behavioral subscales and warrant additional studies to clarify any cause-effect relationship.
