Background: Fishermen are at high risk for suffering from Pterygium disease. Pterygium has the potential to cause decreased visual acuity, chronic irritation, recurrent inflammation, double vision, impaired eye movement and even blindness. This study aimed to analyze the relationship between sun exposure and hat use with Pterygium disease in a group of fishermen in Malabero, Bengkulu City.

Subjects and Method: A case-control study was conducted in Malabero, Bengkulu City. A sample of 120 fishermen consisting of 40 cases and 80 controls selected by purposive sampling. The dependent variable was pterygium. The independent variables were length of sun exposure and the use of a hat. The pterygium case data were obtained from hospital medical records. Other data were collected by questionnaire and then analyzed using Chi-Square.

Results: Fishermen who were exposed to ≥5 hours of sunlight were associated with pterygium disease (OR= 4.32; 95% CI= 0.20 to 0.96; p= 0.038). Fishermen who did not wear a hat while working was associated with pterygium disease (OR= 11.13; 95% CI= 0.78 to 0.54; p= 0.001).

Conclusion: Fishermen who were exposed for ≥5 hours had a high risk of developing pterygium disease, as well as fishermen who worked without wearing a hat were at high risk for developing pterygium disease.
