DENVER — Worse near visual acuity and greater interocular difference in near visual acuity are associated with worse stereoacuity in children, according to a presenter.
“Based on the multivariable regression, we saw worse near VA and greater interocular difference in near VA had the strongest associations with worse stereoacuity,” Silvia Han, OD, told Healio/OSN at the Association for Research in Vision and Ophthalmology meeting.
Han and colleagues examined characteristics that may be associated with stereoacuity, including age and near visual acuity, in children aged 3 to 9 years with previously uncorrected refractive error. Near stereoacuity, monocular accommodative accuracy and cycloplegic autorefraction were also assessed.
Poorer stereoacuity was associated with worse near visual acuity (P < .001) and greater interocular difference in near visual acuity (P < .001). Although stereoacuity improved with age, age was not found to be a significant factor after adjusting for other vision characteristics. Worse stereoacuity was also observed to be associated with higher magnitudes of uncorrected astigmatism, accommodative lag and anisometropia.
Further research is necessary to investigate the influence of refractive error correction on stereoacuity and associated vision characteristics during development, the authors wrote.
