| | Abstract | BACKGROUND: 426 children were examined, using the isotropic photorefraction method (Atkinson et al. 1981). The aim of this study was to analyze whether the frequency of convergent strabismus and/or amblyopia would increase, particularly in cases of high ametropia, and whether the early prescription of spectacles would be beneficial. The preliminary results of this study are presented here.
MATERIALS AND METHODS: 426 children aged between 5 and 12 months were examined. Family history, particularly involving strabismus, ametropia and amblyopia, was ascertained and taken into consideration.
RESULTS: Spherical refraction: 92% of the children were emmetropic or slightly hyperopic (< or = +2.5 D). 3.4% were hyperopic (> +2.5 D spherical equivalent) and 4.6% were myopic (0.9 > or = -2.0 D). Astigmatism: 85% had no or mild (< or = 1.5 D) astigmatism. Values greater than 3.5 D were rarely seen. Anisometropia: 67% of the children had no side-difference and only 2.4% had anisometropia with values greater than 1.5 D. Family history/orthoptic findings: 2.6% of the examined population had strabismus. In 12.2% of all the cases one or more first degree relatives had strabismus. Hyperopia and strabismus were found more frequently in this latter group, namely hyperopia (> +2.5 D spherical equivalent) in 13.6% and strabismus in 11.5%.
CONCLUSIONS: Refractive errors greater than 2.5 D were seldom seen in this study, and yet were more frequently detected in families with a history of strabismus. In our opinion, isotropic photorefraction is a method most suitable to screening these especially high-risk groups. | | Language | ger | | Pub Type(s) | English Abstract
