The human iris contains intricate patterns as unique as fingerprints. For practitioners of alternative medicine, these patterns represent more than just eye color—they’re a map to your health. An tabla de iridología serves as the key to decoding this map, linking specific zones of your iris to organs and systems throughout your body. Whether you’re curious about alternative health assessments or seeking to understand the colorful diagrams you’ve seen in natural health clinics, this comprehensive guide will explain how gráficos de iridología work, their historical development, and the ongoing debate about their effectiveness.
What Is an Tabla de iridología y ¿Cómo funciona?
Un tabla de iridología is a diagnostic tool that divides the iris into zones corresponding to different parts of the human body. Iridologists use these charts to examine the patterns, colors, and markings in your iris to assess your health status, identify potential problem areas, and even predict future health concerns.

According to iridology practitioners, the iris connects to every organ and tissue via the nervous system and brain. When an organ experiences stress or damage, corresponding changes appear in the iris. These changes may manifest as:
- Color variations (white, yellow, brown spots)
- Structural changes (lines, rings, clouds)
- Texture alterations (density, fiber patterns)
- Pigmentation shifts (darkening or lightening)
By consulting an tabla de iridología, practitioners claim to identify which body systems need attention, even before symptoms appear elsewhere in the body.
The Historical Development of the Tabla de iridología
The practice of examining the eyes for health insights dates back thousands of years, but modern gráficos de iridología have a more recent history.

Key Figures in Tabla de iridología Development
Philippus Meyeus (1670): Published the first explicit description of iridological principles in “Chiromatica Medica,” though he didn’t use the term “iridology.”
Ignaz von Peczely (1860s): The Hungarian physician is considered the founding father of modern iridology. Legend claims he noticed iris changes in an owl with a broken leg, inspiring his research. He created the first comprehensive tabla de iridología.
Nils Liljequist (1893): After observing changes in his own iris following medication, this Swedish homeopath published an atlas with 258 black and white illustrations and 12 color illustrations of the iris.
Bernard Jensen (1950s): Popularized iridology in the United States through classes and publications. His tabla de iridología remains influential in modern practice.
Over time, gráficos de iridología have evolved from simple drawings to detailed, color-coded maps. Modern charts often incorporate digital technology for more precise analysis, though the fundamental principles remain similar to those established by the early pioneers.
Understanding Iris Zones on an Tabla de iridología
Un estándar tabla de iridología divides the iris into approximately 80-90 zones, arranged in concentric circles around the pupil. Each zone corresponds to different parts of the body.

Major Zones of the Tabla de iridología
Zonas de iris correctas
- Top Region: Brain, head, sinuses
- Upper Right: Lungs, bronchi, throat
- Upper Left: Heart, chest, breast
- Middle Right: Hígado, vesícula biliar
- Middle Left: Stomach, pancreas
- Lower Region: Intestines, reproductive organs
Zonas de Iris Izquierda
- Top Region: Brain, cerebral circulation
- Upper Right: Spleen, left shoulder
- Upper Left: Heart, thyroid
- Middle Right: Stomach, pancreas
- Middle Left: Adrenals, kidneys
- Lower Region: Colon, bladder, reproductive system
Circular Zones
- Pupillary Zone: sistema digestivo
- Ciliary Zone: Muscular system, circulation
- Autonomic Nerve Wreath: Sistema nervioso
- Outer Iris Zone: Skin, extremities, lymphatic system
- Iris Edge: Skeletal system
Iridologists examine these zones for color changes, structural marks, and other anomalies. The position of a mark within a zone further refines the diagnosis to specific organs or tissues.

Organs and Systems Mapped in the Tabla de iridología
Un tabla de iridología maps virtually every organ and system in the human body to specific locations on the iris. Here’s how some key organs are represented:

Major organ systems as mapped on a standard tabla de iridología
| Organ/System |
Iris Location |
Signs of Potential Issues |
| Corazón |
Left iris, upper quadrant (7-8 o’clock) |
Dark spots, white cloudiness, radial lines |
| Liver |
Right iris, middle area (8-9 o’clock) |
Brown spots, yellowish discoloration |
| Kidneys |
Lower quadrants of both irises (5-6 o’clock) |
White marks, dark spots, structural changes |
| Lungs |
Upper quadrants of both irises (2-3 o’clock) |
White clouds, dark spots, structural breaks |
| Sistema digestivo |
Around the pupil in both irises |
Discolorations, radial lines, dark spots |
| Sistema linfático |
Outer edge of both irises |
White marks, cloudiness, structural changes |
Iridologists believe that examining these specific areas can reveal information about organ function, inflammation, toxicity, and overall health status. The intensity and type of markings may indicate the severity of conditions.

Health Conditions Identified Through an Tabla de iridología
Proponents of iridology claim that various health conditions can be detected by analyzing iris patterns and comparing them to an tabla de iridología. While scientific validation remains limited, here are some conditions that iridologists commonly look for:

Various iris markings and their potential health indications according to iridology
Circulatory Conditions
- Hypertension: Indicated by a ring around the iris, suggesting increased blood pressure.
- High Cholesterol: A white ring around the outer edge of the iris may indicate excessive cholesterol or arteriosclerosis.
- Poor Circulation: Shown by a lack of clear definition in iris fibers.
Problemas digestivos
- Liver Damage: Brown spots in the liver area may indicate liver disease or toxicity.
- Gallbladder Problems: Yellowing in specific areas may suggest gallbladder or bile duct abnormalities.
- Digestive Weakness: Discolorations around the pupil can indicate problems with the digestive system.
Other Conditions
- Inflammation: White streaks or clouds in specific zones may indicate inflammation in corresponding organs.
- Weakened Immune System: White marks throughout the iris may suggest compromised immunity.
- Hormonal Imbalances: Specific markings in endocrine system zones may indicate thyroid or adrenal issues.
“While iridology cannot diagnose specific diseases, it may help identify which organs and systems in the body are under stress and at risk of developing conditions.”
Iridologists emphasize that their practice is not meant to diagnose diseases but rather to identify areas of weakness or stress in the body. They often recommend further medical testing to confirm any suspected conditions.
Scientific Perspective on the Tabla de iridología
The scientific community has expressed significant skepticism about the validity of gráficos de iridología and the practice of iridology in general. Understanding both sides of this debate is important for anyone considering iridology.

Investigación científica que examina la validez de las afirmaciones de iridología.
Argumentos que apoyan la iridología

Resultados clave de la investigación
Several controlled studies have tested iridology’s effectiveness:
- 1979 Study: Bernard Jensen and two other iridologists failed to correctly identify patients with kidney disease by examining iris photographs.
- 1980s British Medical Journal Study: Iridologists could not correctly identify patients with gallbladder disease from iris examinations.
- 2000 Review by Edzard Ernst: Found no benefit from iridology in controlled, masked evaluations of diagnostic validity.
- 2005 Cancer Detection Study: Concluded iridology was of no value in diagnosing common forms of cancer.
The Australian Government’s Department of Health reviewed alternative therapies in 2015 and found no clear evidence of effectiveness for iridology.
Despite these criticisms, many practitioners and patients continue to find value in iridology as a complementary approach to health assessment, particularly when used alongside conventional medical care rather than as a replacement.
