研究了翼状胬肉的遗传度。患者组一级亲属患病率为8.04％,对照组一级亲属患病率为2.24％,遗传度为49.9％。40岁以前年龄组遗传度为42.30±4.44％;40岁以后年龄组遗传度为54.36±5.33％。结果说明:遗传因素在翼状胬肉形成中起重要作用;同时年龄因素亦起一定的作用。
The heritability of pterygium was studied. The prevalence of first-degree relatives in patients was 8.04%. The prevalence of first-degree relatives in control group was 2.24%, and the heritability was 49.9%. The heritability of age group before age 40 was 42.30 ± 4.44%. The heritability of age group after age 40 was 54.36 ± 5.33%. The results show that: genetic factors in the formation of pterygium plays an important role; the same age also play a role.
