Title Outdoor work and the risk of pterygia: A case-control study
Bibliographic information 1998, No.22, p.293-298. Illus. 17 ref.
Abstract To investigate the relationship between outdoor work and pterygium formation in Singapore, cases 61 with pterygium (49 males, mean age 54.2 years) and 125 controls (41 males, mean age 50.2 years), presenting at outpatient clinics of the Singapore National Eye Centre, underwent a face-to-face interview with a standard questionnaire. Demographic data and information on outdoor work and eye protection were collected. 38 subjects (20.4%) were outdoor workers and 148 (79.6%) were indoor workers. Outdoor workers were more likely to be smokers and alcohol drinkers with lower family income and higher sunlight and dust exposure than indoor workers. The crude odds ratio for pterygium in outdoor workers was 7.0. The adjusted odds ratio was 4.2. Efforts should be undertaken to educate outdoor workers to wear proper equipment to protect their eyes against excessive sunlight.
