Of the 80 distributed questionnaires, 56 questionnaires were returned and these have been evaluated. A few questionnaires were not filled out completely. 86% of preventive CHC physicians found the VOV test at 6-9 months difficult. Cover test was considered most often as difficult, by 75% of physicians. Fifty percent considered pursuit movements and 25% motility as difficult (36 questionnaires).
The decision to refer a child based on the screening test was found difficult by 87%, mainly because of a non-cooperative child or doubtful test results (38 questionnaires). 92% admitted that vision screening is sometimes left out at 6-9 months, mostly due to lack of cooperation of the child (39 questionnaires). Only 35% said that they would like to have more training in eye screening.
Questions about adherence to the study protocol showed that 84.4% of preventive CHC physicians estimated their own percentage of unscreened children in the screened group 10% or lower.
