Abstract: The claims of iridologists that the diagnosis of a range of systemic diseases could be aided by studying the presence of structural features at discrete loci on the anterior surface of the iris were investigated. Photographic transparencies of irides of patients suffering from either ulcerative colitis, asthma, coronary heart disease or psoriasis were subjected to a computer image analysis and a single blind manual analysis by comparing them with transparencies of the irides of controls matched by age and sex. The results demonstrate that the diagnosis of these diseases cannot be aided by an iridological style analysis.
