An Evaluation of Iridology

Abstract: Iridology is an analysis of health based on examination of the iris of the eye. One hundred forty-three patients had photographs taken of both eyes. Nine-five patients were free of kidney disease, defined as a creatinine level of less than 1.2 mg/dL (mean, 0.8 mg/dL), and 48 had kidney disease severe enough to raise the plasma creatinine level to 1.5 mg/dL or greater (mean, 6.5 mg/dL). Three ophthalmologists and three iridologists viewed the slides in a randomized sequence without knowledge of the number of pa… Show more

“…Iridologists' claims that there is a possibility of change in iris pattern due to change in health conditions or because of some disease. But long back in 1979 Simon et al [40] and in 1985 Berggren [41] discredited their claims with the help of their research studies.…”

“…Conclusion: This experimental study verifies that the rich amount of iris signs in the human eye is likely to lead to reasonable explanations of the symptoms of the patient. Simon et al (1979) have carried out an important and instructive investigation. Three iridologists were asked to analyse in a randomized order the stereophotos of patients with chronic kidney disease and those of normal subjects.…”

“…İridoloji 19.yy'ın sonlarına doğru Ignatz von Peczely tarafından ortaya çıkarılmıştır. Farklı hastalıkların iriste farklı bölgelerde değişiklikler meydana getirdiğini keşfeden Peczely, irisin haritasını çıkarmaya başlamıştır [14]. İris haritasını tamamlayarak son haline getiren Bernard Jensen, iridolojinin yaygınlaşmasına önemli katkıda bulunmuştur [15].…”
