Iridology
Iridology

Background

Iridology practitioners diagnose disease or medical conditions by examining the colored portion (iris) of the eye.

Iridology is not used to treat disease. It is used to diagnose disease, but there is no good scientific evidence to support this use.
There isn't enough reliable information to know if iridology is safe. Since it is not an invasive practice and does not involve taking any substance, it is not likely to be harmful. But since iridology is not proven to accurately diagnose disease, there is concern that an iridology diagnosis could be wrong or that medical conditions could be missed. An inaccurate or missed diagnosis could result in no treatment, delayed treatment, or inappropriate treatment.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if iridology is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Effectiveness

NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Likely effective Effectiveness definitions
Possibly effective Effectiveness definitions
Likely ineffective Effectiveness definitions
Possibly ineffective Effectiveness definitions
Insufficient evidence Effectiveness definitions
  • Diagnosing cancer. Early research shows that iridology practitioners do not consistently or accurately diagnose various cancers including breast, ovary, uterus, prostate, or colorectal cancer.
  • Diagnosing gallbladder disease. According to iridologists, gallbladder disease is a condition easily identified. But there is evidence that iridology practitioners do not consistently or accurately diagnose gallbladder disease.
  • Diagnosing high blood pressure. According to iridologists, people with high blood pressure are more likely to have a "neurogenic" constitution.
  • Diagnosing kidney disease. There is evidence that iridology practitioners do not consistently or accurately diagnose kidney disease.
  • Diagnosis of other diseases and medical conditions.
More evidence is needed to rate iridology for these uses.

Action

Iridologists believe that sections of the eye correspond to specific organs or systems of the body. They think that abnormalities in the appearance of the eye suggest disease or the likelihood of getting a particular disease. Some iridologists believe that the appearance of the eye can be used to suggest dietary needs. However, there is no scientific support for these beliefs.
