Relationships of heredity and dry eye with pterygia in black African patients
Abstract
36% of the cases and 10% of the controls had positive history (OR 4.5, p<0.05 chi square test). 7% of the cases and 17% of the controls had poor tear film (OR 0.24, p<0.05 chi square test). A positive family history was associated with pterygium occurrence. Dry eye was not associated with pterygia.
