To examine the accommodative amplitude and convergence in 10-year-old prematurely born children previously screened for retinopathy of prematurity (ROP) and to compare with full-term controls of the same age.
Two-hundred and thirteen prematurely born and 217 children born at term were included. Accommodative amplitude and near-point convergence were assessed, together with best-corrected visual acuity (VA). A questionnaire was answered regarding possible problems at school.
Binocular accommodation (P = 0.03) and convergence (P = 0.003) were significantly poorer in prematurely born children. Accommodation was correlated to neurological findings in the preterm group, but not to the degree of prematurity or stage of ROP. Regarding convergence there were no correlations to neurology, stage of ROP, or degree of prematurity. For neither accommodation nor convergence were any correlations with distance and near VA found. Preterm children had a higher prevalence of school problems, and there was an association with poor accommodation.
Prematurely born children had poorer accommodation and convergence than full-term children, but no association with near VA was found. The reduction of accommodative amplitude and convergence was small and was probably of little clinical significance. However, it may have additional effects on other ophthalmological problems and school problems in the preterm group.
研究曾接受早产儿视网膜病变（ROP）筛查的10岁早产儿童的调节幅度和集合功能，并与同龄足月儿进行比较。
纳入213名早产儿童和217名足月儿。评估调节幅度、近点集合以及最佳矫正视力（VA）。此外，还对可能存在的学校相关问题进行了问卷调查。
早产儿童的双眼调节功能（P = 0.03）和集合功能（P = 0.003）明显较差。在早产组中，调节功能与神经学检查结果相关，但与早产程度或ROP分期无关。关于集合功能，其与神经学、ROP分期或早产程度均无相关性。调节功能和集合功能与远视力和近视力均无相关性。早产儿童存在学校相关问题的患病率更高，且与调节功能不良有关。
早产儿童的调节功能和集合功能比足月儿差，但与近视力无关。调节幅度和集合功能的降低幅度较小，可能临床意义不大。然而，这可能对早产组的其他眼科问题和学校相关问题有额外影响。
