Astigmatism in Bangladeshi and white school entrants in East London: a prospective comparative study

A prospective comparative study was undertaken to determine the prevalence of significant astigmatism in school entrants living in the same area of East London. Thirty-one Bangladeshi and thirty-one white school entrants were refracted in two local state schools. In the Bangladeshi group, 7 right and 5 left eyes had more than 1 dioptre of astigmatism. Most of this astigmatism was with the rule. In the white group, 1 left eye had more than 1 dioptre of astigmatism. This study has shown a statistically significant incidence of astigmatism in an ethnic group in East London. This difference between two racial groups living in the same area of East London has not previously been documented. In our study, Bangladeshi school entrants may be at greater risk of amblyopia if their refractive error is not identified and corrected.
