Constitutional Iridology
6. Constitutional Iridology
Last Updated: March 24, 2026Constitutional iridology is the assessment of an individual’s inherited iris structure to identify long-term physiological tendencies, organ predispositions, and constitutional health patterns. PupilMetrics implements Dr. Josef Deck’s classification system, expanded and annotated by Dr. Bryan K. Marcia’s CCVE manuscript. > **Platform note:** The constitutional type selector is available on **Windows desktop only**. The constitutional panel...
6.1 Background & Theoretical Basis
Last Updated: March 24, 2026Constitutional iridology originated with the German iridologist Dr. Josef Deck, whose work in the mid-20th century systematically grouped iris structural patterns into repeating constitutional categories. Unlike topographic iridology (which maps specific iris zones to specific organs), constitutional typing focuses on the **overall fiber texture, pigmentation pattern, and structural qualities** of the iris as a whole...
6.2 The 34 Constitutional Types
Last Updated: March 24, 2026PupilMetrics includes 34 constitutional types organized into six groups: #### Group 1 — Lymphatic (8 types) The Lymphatic constitution is the most common in light-eyed populations. The base iris is typically light blue-grey with well-defined, silk-like or wavy fibers. Subtypes are defined by the presence and character of tophi (whitish connective-tissue deposits), pigmentation, and fiber...
6.3 Selecting a Constitutional Type
Last Updated: March 24, 2026Constitutional type selection is performed on the **”Both Eyes Captured”** screen, which appears after both left and right eye photos have been taken. At this point the practitioner has both eye images visible side by side — the appropriate moment for constitutional assessment, since Deck’s system requires evaluation of both irides together. **To select a...
6.4 Constitutional Panel in Analysis Results
Last Updated: March 24, 2026When a constitutional type has been selected, an amber-bordered Constitutional Iridology panel appears in the Analysis Results screen, positioned after the bilateral comparison card and before the Natural Medicine Therapy panels. The panel contains three collapsible sections: Section Content Default Iris Description Full description of the iris structural and pigmentation features that define this constitutional...
6.5 Constitutional Section in the PDF Report
Last Updated: March 24, 2026When a constitutional type is selected, the exported PDF includes a dedicated Constitutional Iridology section inserted between the bilateral ANW (collarette) assessment and the Natural Medicine therapy sections. The PDF section uses a light, print-optimized layout: Part Appearance Header bar Warm cream background — constitution name in bold, group badge in solid amber Iris Description...
6.6 Clinical Guidance & Limitations
Last Updated: March 24, 2026**Training required.** Accurate constitutional typing requires formal training in iridology. Practitioners unfamiliar with constitutional iridology should complete dedicated training before using this feature clinically. **Not a diagnosis.** Constitutional patterns describe inherited tendencies, not diagnoses. A patient with a Cardio-Pathological constitution has an inherited structural predisposition — they do not necessarily have heart disease. Constitutional findings...
