Iris Analysis: Introduction

Session 3 Overview

• Iris fibre grading: Silk, cotton, linen, hessian,

net

• Fibre signs: radial, transverse, thin, thick

• Colour & pigment

Structural Signs in the Iris• Structural signs in the iris are a result of the separation

or aberration of the radial fibres/trabeculae.

• 3-4 layers of these fibres exist in the anterior border

region of the iris.

• Separation/aberration of fibres occurs as a result of

reflex signals from parts of the body conveyed via its

neuro- and biochemistry.

• Signals delivered to the iris can be genetically

determined (genotype) or acquired as a result of life

events & environment (phenotype)(e.g. nutrition,

trauma, climate, social life).

Acute health problem = dysfunction (hyperfunction

hypofunction – nerve function, circulation, nutrition)

Chronic health problem (functional + structural weakening –

nerve function, circulation, nutrition + cellular/tissue/organ

degeneration)

Sub-acute health problem (hypofunction – nerve function,

circulation, nutrition + structural weakening)

Degenerative health problem (further functional + structural

weakening/breakdown – nerve function, circulation, nutrition

+ cellular/tissues/organ/systems degeneration)

Structural Signs in the Iris

White/light coloured, often thickened trabeculae –

fibres are raised above the level of the others –

indicate inflammation/irritation in the tissues they

reflex to.

These fibres can be associated with acute conditions

(e.g. sprains, fractures, pain, fevers) but can also be

related to long-standing (sub-acute/chronic)

conditions.

It is usually an indication of increased physiological

activity in the reflexing area (increased nervous,

circulatory activity)

Structural Signs in the Iris

Raised white/light fibres in the iris

Structural Signs in the IrisLight grey lacunae – superficial fibres are

separated revealing the underlying layer &

appear light grey in colour.

Where iris fibres/trabeculae are separated

revealing lower layers of stromal fibres the

term “lacuna” is applied (plural “lacunae”).

A lacuna is a separation of the iris fibres

which indicates a weakness or potential

weakness in the organ/tissue that reflexes

to it.

Structural Signs in the Iris

Light grey/”sub-acute” lacunae

© Endeavour College of Natural Health endeavour.edu.au 11

Structural Signs in the IrisDark grey lacunae –fibres of the first two

layers are separated revealing the

underlying deeper layer & appear dark

grey in colour.

Lacunae of this depth indicate a chronic

(long standing, unresolved) condition

associated with the reflex organ/tissues or

an inherently weak organ/tissues.

If a chronic condition associated with the

reflex organ/tissues currently exists both

function and structure are likely to be

effected.

© Endeavour College of Natural Health endeavour.edu.au 12

Structural Signs in the IrisDark grey lacunae contd

Where there is no current health problem associated with

the organ that reflexes to the dark grey lacuna, there is likely

to be an inherited weakness and a potential risk of future

health problems

Questioning of the patient should try to determine whether

there is a current or potential problem associated with the

organ that corresponds to the lacuna – is it an inherited or

acquired weakness?

Where a potential health risk is identified a preventive

approach may be taken to minimise the risk.

Structural Signs in the IrisBlack lacunae –fibres of the first three or

four layers are separated revealing the

underlying deep layer & appear black in

colour.

Lacunae of this depth indicate a

degenerative (long standing, unresolved)

condition associated with the reflex

organ/tissues or an inherently weak

organ/tissues.

If a chronic condition associated with the

reflex organ/tissues currently exists both

function and structure will be effected.

© Endeavour College of Natural Health endeavour.edu.au 14

Structural Signs in the IrisBlack lacunae contd

As with the dark grey lacunae if there is no current health

problem associated with the organ that reflexes to the black

lacuna, there is likely to be an inherited weakness and a

potential risk of future health problems

Questioning of the patient should try to determine whether

there is a current or potential problem associated with the

organ that corresponds to the lacuna – is it an inherited or

acquired weakness?

Where a potential health risk is identified preventive

measures may be taken to minimise the risk.

Structural Integrity of the IrisDensity/texture of iris fibres indicates the structural integrity

of an individuals’ body (systems, organs, tissues) and the

corresponding function of those tissues.

Iris fibre density/texture is determined largely by how close

together the fibres are

High density generally indicates an individual with a strong

constitution (a strong resilience to disease/illness; ability to

recover quickly when sick)

Low density/open texture (many lacunae) generally indicates

a poor constitution (poor resilience to disease/illness; slow to

recover)

© Endeavour College of Natural Health endeavour.edu.au 17

Taken from Bernard Jensen’s teaching

slides (circa 1979)

High Fibre Density = Strong Constitution

© Endeavour College of Natural Health endeavour.edu.au 18

Poor Fibre Density = Weak Constitution

© Endeavour College of Natural Health endeavour.edu.au 19

Iris Fibre Density & Texture The quality of fibre structure/density and texture is directly

related to:

• The general constitution of the individual.

• Nerve, blood, lymph & nutrition supply to the associated

tissues.

• Integrity & metabolic efficiency of the associated tissues;

• The body tissues’ capacity to resist and recuperate from

disease.

Fibre structure density does not change significantly in one’s

lifetime (e.g. regardless of how much effort is invested through

a healthy diet/lifestyle modification one’s iris structure will

largely remain the same) – genetically determined

© Endeavour College of Natural Health endeavour.edu.au 20

Various factors can influence iris fibre density/texture:

•Genetics;

•Diet & nutrition;

•Exercise;

•Lifestyle;

•Environment;

•Stressors.

Iris Fibre Density & Texture

Iris Fibre Density & Texture

Optimal iris fibre structure should be:

–Straight

–Densely-packed

–Clearly visible

–Not too thick

–Not too light/bright

For standardisation of iris fibre structure, and related

constitutional strengths the iris is divided into five (5) iris

fibre ‘gradings’:

Silk

o Considered the strongest constitution by Jensen and

others.

o Straight and dense iris fibre structure (like fine combed

hair).

o Strong resistance to disease and excellent recovery from

illness.

o Commonly described as ‘having the constitution of an

ox’, it takes a lot to bring them down.

o Excellent work ethic and stamina, still going after others

have collapsed from exhaustion, take on gargantuan

tasks single-handedly.

Silk

o Not too many pure silk irises exist today in the under

50’s. This reflects lifestyle and environmental changes

o Constitutional strong and have a great ability to recover

o Emotionally they have difficulty comprehending others

lack of stamina and strength to match their own.

o They may lack emotional empathy, tactfulness,

diplomacy, understanding and sensitivity

o Can be hard on themselves and hard on others, strong

work ethic; straight line of fibres indicate straight line

thinking, can be very competitive

o Often consider illness a sign of weakness

© Endeavour College of Natural Health endeavour.edu.au 27

Cotton(Silk/Linen)

o A relatively strong constitution (often referred to as

Silk/Linen)

o Dense iris fibre structure that is ‘wavy’ – possible

indication of nervous over-stimulation and irritation of

underlying body tissue

o Will have some separation of iris fibres and openings

(lacunae) in the iris fibre structure

o May have some clouding, colours and other signs

o Illness usually caused by emotional disturbance,

accidental damage/trauma or functional disorders

Cotton (Silk/Linen)

o Often children of a Silk parent. Dorothy Hall describes

them as “top of average” (Hall 1980)

o Need movement and activity to maintain wellness.

o Essential that they drink lots of water to avoid build up of

acids within their system

o Emotionally similar to silk, don’t deal with others

emotionally well, “soldier on” attitude, can be competitive

© Endeavour College of Natural Health endeavour.edu.au 31

Linen

o Average constitution (the average individual)

o Fibres more wavy than Cotton with more separation of

iris fibres and/or openings (lacunae) in the iris structure

o Nervous system deficiencies

o Not too strong and not too weak.

o They get tired, cross, moan a little. They have more

awareness of their own physical limitations than Silk or

Cotton.

o Don’t take on huge tasks alone; prefer to work in groups

and to their strengths.

o Experience ill-health more frequently than first two

structural types; take longer to fully recover

Hessian

• Inherently weaker structure

• Much separation of iris fibre structure with numerous

small and/or large lacunae (A ‘torn-up’ appearance)

• Higher level of emotional response rather than action-

orientated response (‘must get round to it some day’)

• Tend to have glandular and hormonal issues, mood

swings, reduced stamina, give up half way through

• Will have other signs throughout the iris (lymphatic

clouding / rosary etc)

• Nervous & circulatory system deficiencies

• Nutritional demand will be greater than other structural

types

Net

• Extremely poor iris fibre texture

• Significant separation of iris fibres with lots of small

and/or large lacunae (More ‘torn-up’ than the Hessian

grading)

• May have numerous other signs (crypts/lymphatic

clouding/rosary)

• Glandular/(Endocrine/Hormonal) disturbances or

connective tissue weakness

• Nutritional demand is much greater – tissues use up

more nutrients to function effectively

Iris Fibre Aberrations

Normal trabeculae: straight, radial appearance, not too

thick or light in colour

Transversals: trabeculae/fibres that cross over radial

fibres; can indicate tendency to irritation, inflammation,

pain (especially if also light/white & thickened)

Vascularised transversals: pink/red transversals;

connective tissue sheath has degenerated; can indicate

pain, congestion, significant irritation in the reflex area

Rarefaction: where fibres in an area of the iris have

decreased in density (further apart but don’t form a

lacuna); same indications as a light grey lacuna

© Endeavour College of Natural Health endeavour.edu.au 38

Transversal – note the

proximity of several thick white

fibres in the area highlighted.

This suggests irritation,

inflammation of tissues in this

area – most likely the spine or

associated muscles/nerves

Rarefaction

Can you identify other areas of rarefaction in this iris?

Colour and Pigments in the Eye

General iris colour is largely determined genetically & is

due to pigment in the iris.

• Brown irises – heavily pigmented

• Hazel – moderately pigmented

• Green – greater pigment than blue irises

• Blue – slightly pigmented

Deposition of pigments in the iris can change within a

lifetime but these usually occur as discrete “spots” or

“psora” – pigment diffuses up through the stroma as a

result of a reflex stimulus.

These deposits may result from unhealthy life choices

over time.

Colour and Pigments in the Eye

Pigment deposits & their indications

• Brown: liver-related issues

• Orange: pancreatic issues (usually blood sugar

regulation)

• Straw Yellow: kidney-related issues

Other discolourations in the eye

• Brown pigment in the sclera: liver-related issues

• Off-white/cream areas: chronic

congestion/inflammation; accumulation of metabolic

wastes

© Endeavour College of Natural Health endeavour.edu.au 48

Colour and Pigments in the Eye

The colour brown is suggestive of liver dysfunction.

Practitioners could also consider dysfunctions within fat,

and protein metabolism.

© Endeavour College of Natural Health endeavour.edu.au 49

The colour yellow is suggestive of kidney dysfunction.

Practitioners could also consider dysfunctions of protein

metabolism.

Colour and Pigments in the Eye

© Endeavour College of Natural Health endeavour.edu.au 50

The colour orange is suggestive of pancreatic dysfunction, in

particular dysfunctions of glucose metabolism and blood-sugar

imbalances.

Colour and Pigments in the Eye

© Endeavour College of Natural Health endeavour.edu.au 51

Areas of white/off-white/cream

can indicate elevated metabolic

acidity levels. The sign may also

suggest kidney dysfunction with

an inability to eliminate uric acid

(lowered protein metabolism),

lactic acid (muscular activity)

and other acidic compounds

produced from metabolic

processes
