Page 69 - DISINVESTMENT AND IMPLEMENTATION OF VISION SCREENING TESTS BASED ON THEIR EFFECTIVENESS

The effect of omitting an early population-based vision screen in the Netherlands: A micro-simulation model approach
cohort, specific eye examination during general screening between the age of 6 and 24 months was omitted. The first results of this disinvestment study confirm the predictions of the microsimulation model for the screens at age 6–9 months: the screened and unscreened groups differed little in the proportion of children referred and found to have amblyopia. On further examination, all cases of amblyopia detected were caused by strabismus, not by refractive errors, and most cases of strabismic amblyopia were found because the parents had noticed the strabismus.12 At age 14–24 months, referral was still mostly based on conspicuous strabismus or other visually apparent disorders noted by parents or screening physicians, but, although still a minority, specific eye screening led to more referrals than at 6-9 months.13
