Iridology
Description: The diagnosis of medical problems by closely inspecting patterns and colors in the iris (part of the eye). Practitioners believe that sections of the iris correspond to parts of the body and reveal whether those body parts are healthy or diseased. Based on the diagnosis, herbs or homeopathic treatments are often prescribed.
Research Summary: Studies indicate that inspection of the iris is not a valid way to diagnose disease. Also, there is no evidence that individuals with autism spectrum disorders have abnormalities in the iris. Therefore, iridology is an inappropriate intervention for autism spectrum disorders.
Recommendations: Iridology is not a useful intervention for individuals with autism.
