Iridology, one of complementary and alternative medicine (CAM), is the diagnosis of the medical conditions through noting irregularities of the pigmentation in the iris. Iridological constitution has a strong familial aggregation and is implicated in heredity. Apolipoprotein E (apoE) gene polymorphism is one of the most well studied genetic markers of vascular disease. Then I investigated the relationship between iridological constitution and apoE polymorphism. I classified 87 hypertensives patients with family history of cerebral infarction and 79 controls according to Iris constitution, and determined apoE genotype. Neurogenic type in hypertensives was 32.2% compared with 16.5% in controls (P<0.001). No differences in the apoE genotypes frequencies were observed in patients compared with that in controls ( 2=0.726, df=2, P=0.696). However, in population with 3/ 4 genotype, the frequency of neurogenic constitution was significantly higher in hypertensives than in controls (60% vs. 0%) ( 2=5.265, df=1, P=0.022). These results could be implied that apo E 3/ 4 genotype and neurogenic Iris constitution are risk factors for hypertension.
