CHAPTER 4
RESULTS
In total, 25 CHC physicians were observed for a period of eight weeks, four days weekly, while examining 503 children aged 1-45 months. Of these 503 children, 169 were excluded because they were included in the study group of the OVAS study. Two CHC physicians were excluded due to a very low number of children examined and one child was excluded because the observation form was missing (Figure 1). In the age group 1-24 months 239 children (73%) were included, 82 (34%) of which were 1-4 months of age and 157 (67%) were 6-24 months of age. The other 90 (27%) children were 36-45 months of age. The observations in the first week had been done simultaneously by the two orthoptic students, and after the first week of observation these were compared and found to be in good concordance. The findings of both observers were matched.

* Children born between January1st and June 30th 2012 without specific eye screening.
They participate in the OVAS study about the effect of omission of eye screening at age 6-24 months on the detection of amblyopia comparing two consecutive birth cohort with and without specific eye screening.
* * YHC physicians who examined less than 5 children during the observation period were excluded.
