![]() Inflammation can be an early indicator of many diseases.Digestive problems may manifest as discolored areas around the pupil and indicate stomach or intestinal issues.Some believe that depression may be a manifestation of liver disease. The liver disease shows up as brown spots in the liver portion of the iris.Hypertension (high blood pressure) presents as a ring around the iris.Here are several conditions iridology claims to detect: What diseases does iridology claim to detect?Īlthough iridology doesn’t provide a specific diagnosis, it may point to a particular part of the body that isn’t functioning normally and is at risk for certain diseases. This study and others suggest that iridology is not a reliable method for detecting potentially life-threatening diseases. Iridology was able to identify the correct diagnosis in only three people. In one study of 110 patients, 68 people had a confirmed diagnosis of various types of cancer, while the remaining patients were healthy. Additionally, the medical industry does not regulate iridology. Therefore, it’s generally considered a controversial practice. A naturopathic doctor examines the iris for certain features, including:ĭiscoloration in the sclera (white part of the eye)Īlthough many naturopathic doctors use iridology techniques, the current medical evidence doesn’t support purported claims of iridology. His iridology chart depicts various parts of the iris representing different body organs, such as the kidney, liver, lungs, and stomach. Ignatz von Peczely, a Hungarian physician, developed the idea of iridology in the late 1800s. Iridology, or iridodiagnosis, is an alternative medicine practice that involves studying the iris to determine information about systemic health and help diagnose medical conditions. In this article, we’ll explore this idea and discuss whether or not iridology is a valid technique for diagnosing medical conditions. You may have heard that the iris can tell us a wealth of information about our health. Heterochromia.Some consider the iris the most visually striking part of the eye, with an array of brown, blue, green, hazel, and many shades aside from eye color, the iris controls light entering the eye by contracting and expanding the pupil.

Sectoral heterochromia often resembles an irregular spot on the iris of the eye and does not form a ring around the pupil. In people with sectoral heterochromia, also known as partial heterochromia, one part of the iris is a different color from the rest. For example, they may have one blue eye and one brown eye. People with this condition have two different-colored eyes. Eyes that have this pattern may be referred to as “cat eyes.” The outer color is considered to be the true iris color in people with central heterochromia.Ĭentral heterochromia tends to occur in irises that have low levels of melanin. The inner ring often seems to have “spikes” of different colors that radiate from the pupil or the black circle at the center of the iris. Usually, the outer ring of the iris is one color while the inner ring is another. The different types of heterochromia of the eye include: Central heterochromiaĬentral heterochromia is characterized by having two different colors in the same iris.
