Visual problems in Hong Kong primary school children

School children in Hong Kong who fail an Education Department vision screening at the age of five or six are referred to eyecare agencies for a full eye examination. Three hundred and ninety-one consecutive cases seen at the Hong Kong Polytechnic were analysed to obtain a breakdown of the type of refractive errors causing reduced vision among children starting primary school. There was a tendency towards myopia and with-the-rule astigmatism. Exotropia was more commonly encountered than was esotropia. Strabismus and amblyopia were predominantly associated with anisometropia and astigmatism. Key words: vision screening, retractive error, primary school children, Chinese, strabismus. Hong Kong
