简要总结
The objective of this prospective study is the treatment of esotropia by prescribing the full precise optical correction of refractive errors in children up to 3 years old.
详细描述
This investigation includes children with esotropia associated with hyperopia, hypermetropic astigmatism, myopia, myopic astigmatism and minor ametropias. All children are prescribed full optical correction of refractive errors with special attention to astigmatism up to 0.5 Dpt to achieve maximal clear image on the retina of both eyes.If necessary, direct occlusion or penalization were administered to the children. The investigators suggest that this approach will give good results in the treatment of esotropia.

结局指标
主要结局
The angle of deviation
时间窗: 2 years
The absolute success is defined as restored symmetrical eye position.Qualified success is considered as reduction of the angle of deviation. Patients are examined 24 months later to assess outcome of treatment.
