The prevalence of and risk factors for pterygium in an urban Malay population: The Singapore Malay Eye Study (SiMES)

Abstract

The prevalence of pterygium is 12.3% among urban Malays aged 40 years and older and higher than Chinese of similar ages in Singapore. Independent associations of pterygia with increasing age, male sex, outdoor occupations and systemic factors like blood pressure suggest a complex and multi-factorial aetiology for this condition.
