Shapira Y, et al. – Analysts assess the prevalence of amblyopia, display strabismus and amblyopia risk factors (ARFs) among young adults in Israel and aim to analyse trends over time of prevalence rates. Among young adults, the prevalence of unilateral amblyopia, and also the prevalence of present strabismus, reduced significantly over a period of a generation. The prevalence of strabismic, bilateral or severe (both unilateral and bilateral) amblyopia remained stable. The establishment of the national screening programme for children and the improved utility of treatment for amblyopia and strabismus coincide with these trends. Thus, it is possible that these early interventions resulted in modification of the 'natural history' of these conditions and their prevalence in adolescence.
