Abstract:
To study the heritability (h~2) of pterygium, the morbidity of pterygium in the first degree relatives of 123 patients was found to be 8.04％ h~2=49.9％ and that of the control group was 2.24％. However, for subjects under 40 years of age, the h~2 was 42.3％, while for subjects over 40 years of age, h~2=54.36％. It was concluded that the genetic factor plays an important role in the pathogeny of pterygium and the age factor also exerts some effects.
