Aetiology of climatic droplet keratopathy and pterygium.

PMCID: PMC1039379  PMID: 7387947

Abstract

The association of various personal, occupational, and environmental factors with climatic droplet keratopathy and pterygium was examined in a group of Australian Aborigines. Climatic droplet keratopathy was seen especially in aboriginal males who had worked as stockmen for more than 20 years. Although no definite association with a single causal factor could be made, there is circumstantial evidence for the importance of ultraviolet radiation. Pterygium was more commonly seen in those who worked outside, and it was positively correlated with lower latitudes and high ultraviolet levels.
