John Andrews Modern Iridology Research - advancing iridology



Please feel welcome to download the following articles for your own information. Many more research articles, discussion & findings are published and referenced in the John Andrews Iridology Text books and the various volumes of the Advanced Iridology Research Journal.This research is authored by John Andrews and many others where indicated.


John Andrews & colleagues are currently actively involved in researching, documenting, pioneering and presenting new material pertaining to the following aspects of modern iridology understanding and inner pupillary border (IPB) assessment:


  • "M" Sign on the IPB
  • Elephants Sign on the IPB
  • "S" Sign on the IPB
  • Progesterone Ratio Signs for the IPB & Iris
  • Neutropenia Tendency & Modern iridology
  • The HPA Axis & Modern Iridology
  • Frontal Neuroendocrine Tissues & the IPB
  • Modern Iridology Iris & IPB Signs associated with Chronic Fatigue Syndrome
  • New Iris Topographic Research: Citric Acid Cycle Cellular Disruption Chart
  • Longitudinal Iris Developmental Research Study
  • Potential Osteopenic Risk Factors identified through frontal ocular microscopy
  • Further Collarette & IPB Classifications
  • Blood Types & Modern iridology Classification
  • Ongoing New Pupillary Zone Topographical Research (1998-2009) with an emphasis on a fuller understanding of the psychoneuroendocrinoimmunological (PNEI), extracellular matrix (ECM), PAX-6 gene & cellular expression interactions with the hypothalamus, hippocampus and other aspects of the limbic & hormonal systems


The following section will have a full complement of 26 articles by Summer 2010.

In the meantime a new and full comprehensive review of both the many positive and negative iridology-related research studies covered in medical journals are featured for the first time in a new chapter on Modern Medical Iridology Research in the new 2008 book by John Andrews, published in England, on Iris & Pupillary Signs, 3rd Edition.
