Abstract
Purpose To compare visual performance between emmetropic and uncorrected moderately hyperopic preschool-age children without strabismus or amblyopia. Design Cross-sectional study. Methods SETTING: Multicenter, institutional. PATIENT OR STUDY POPULATION: Children aged 4 or 5 years. INTERVENTION OR OBSERVATION PROCEDURES: Visual functions were classified as normal or reduced for each child based on the 95% confidence interval for emmetropic individuals. Hyperopic (≥3.0 diopters [D] to ≤6.0 D in the most hyperopic meridian; astigmatism ≤1.50 D; anisometropia ≤1.0 D) and emmetropic status were determined by cycloplegic autorefraction. MAIN OUTCOME MEASURES: Uncorrected monocular distance and binocular near visual acuity (VA); accommodative response; and near random dot stereoacuity. Results Mean (± standard deviation) logMAR distance visual acuity (VA) among 248 emmetropic children was better than among 244 hyperopic children for the better (0.05 ± 0.10 vs 0.14 ± 0.11, P <.001) and worse eyes (0.10 ± 0.11 vs 0.19 ± 0.10, P <.001). Mean binocular logMAR near VA was better in emmetropic than in hyperopic children (0.13 ± 0.11 vs 0.21 ± 0.11, P <.001). Mean accommodative response for emmetropic children was lower than for hyperopic subjects for both Monocular Estimation Method (1.03 ± 0.51 D vs 2.03 ± 1.03 D, P <.001) and Grand Seiko (0.46 ± 0.45 D vs 0.99 ± 1.0 D, P <.001). Median near stereoacuity was better in emmetropic than in than hyperopic children (40 sec arc vs 120 sec arc, P <.001). The average number of reduced visual functions was lower in emmetropic than in hyperopic children (0.19 vs 1.0, P <.001). Conclusions VA, accommodative response, and stereoacuity were significantly reduced in moderate uncorrected hyperopic preschool children compared to emmetropic subjects. Those with higher hyperopia (≥4 D to ≤6 D) were at greatest risk, although more than half of children with lower magnitudes (≥3 D to <4 D) demonstrated 1 or more reductions in function.
