斜视和弱视是在瑞典Vasteras地区出生于1979年或1980年的一组儿童中进行研究的。40%的儿童在1岁时参加了自愿眼科检查。本研究包括1979年至1988年期间在该地区三家眼科诊所中任何一家被诊断为斜视和/或弱视的所有儿童。斜视病例大多由父母发现，而微斜视和直眼弱视是在儿童健康中心的4岁一般筛查中发现的。在57例有弱视（n=31）和无弱视（n=41）的病例中，可以获得1至6岁之间的几个屈光值。在本研究中，我们集中在显性内斜视和外斜视。这项研究的目的是描述斜视发病前后屈光的变化，并建立风险指标，以确定有斜视风险的人群。我们发现内斜视患者在检测到斜视时比外斜视患者表现出更明显的远视。随着时间的推移，这种差异变得更加明确，因为在内斜视病例中斜视眼的远视增加，而在大多数外斜视眼中屈光不正保持不变。同样明显的是，与外斜视病例相比，内斜视病例在斜视发作后经常发生屈光参差。偏斜内斜视眼的屈光不正增加可能与注视眼的正视化相结合。
Strabismus and amblyopia were studied in a cohort of children born in 1979 or 1980 in the area of Vasteras, Sweden. Forty percent of the children had participated in a voluntary eye examination at 1 year of age. All children diagnosed as strabismic and/or amblyopic between 1979 and 1988 at any of the three eye clinics in the area were included in this study. Strabismic cases were mostly detected by the parents while microstrabismus and straight eye amblyopia were found at the general 4 years of age screening at children's health centres. In 57 cases with (n=31) and without amblyopia (n=41) it was possible to obtain several refraction values between 1 and 6 years of age. In this study we concentrated on manifest esotropia and exotropia. The aim of the study was to describe changes of refraction before and after onset of strabismus and to establish risk indicators that identified populations at risk of developing strabismus. We found that patients with esotropia show a more pronounced hypermetropia than exotropic cases at the time of detection of strabismus. This difference becomes more definite over time, since hypermetropia increased in the deviating eye in the esotropic cases while refractive errors remained stationary in most of the exotropic eyes. It was also apparent that anisometropia frequently developed after onset of strabismus in esotropic cases in contrast to exotropic cases. An increasing refractive error in the deviating esotropic eye could be combined with an emmetropisation of the fixating eye.
