Progressive myopia is an acknowledged issue, and a developing body of knowledge has grown concerning its causes and remedies. This knowledge has to be incorporated into the consulting room routine, and some first thoughts on this are outlined below.

Significance of myopia

Prevalence of myopia in children is increasing globally, particularly in east Asia where 69% of 15-year-olds are myopic, an increase of 23% in the last decade.1 This is even more marked in Singapore, where 86% of 15-year-olds are myopic, with Africa representing the other end of regional variations with an incidence of 5%.
