Sclerology · Atlas

1. Introduction

Version followed: Leonard Mehlmauer's Grand Medicine "Eyology" sclerology (the manual SCLEROLOGY: A New View of an Ancient Art and the Grand Medicine BASICS and Advanced courses), with the certification route now run by the International Iridology Practitioners Association (IIPA). Other teaching lines (an early introductory book by Jack Tips, independent iridology schools) are noted where they differ. This guide describes the method as its organisations publish it and sets out the psychotherapist's own work alongside it; the psychotherapist does not perform, sell, prescribe or recommend sclerology; the guide covers how to work with clients who use it, are offered it, or practise it.

What it is, as its organisations describe it. Sclerology is the reading of markings in the whites of the eyes. Grand Medicine places it within "Eyology", a term its site says was "coined in 1995 by Leonard Mehlmauer" for the arts linking eye markings and colourings to health and personality; Eyology groups iridology, sclerology and pupilology. Sclerology is said to involve the whites of the eyes including the conjunctiva and episclera, and to have four theoretical sub-sciences. [source: Grand Medicine, Eyology page]

Core idea of change (as held by the method). Practitioners hold that the iris shows inherited or genetic predisposition, while the sclera shows current stress, congestion and pathology: the sclera "say[s] what's happening now" and is said to verify and roughly double iris findings. The reading is followed by an outline of findings and diet, lifestyle, herb and supplement recommendations; the client is expected to understand "how they got the problem" and act on it. Grand Medicine's teaching also refers to etheric, emotional, mental, psychic and spiritual energies; IIPA describes sclerology as giving insight into "systemic and emotional health". These are the method's own claims, reported here as attributed beliefs. [source: Grand Medicine manual and Eyology pages; Advanced course page; IIPA Sclerology page]

Claimed origins. Grand Medicine credits ancient Chinese healers with using the sclera to verify acupuncture areas and cites an unnamed "thousand-year-old Chinese healing manual"; the manual's title calls it "an ancient art"; another seller's chart refers to unnamed "European masters". Grand Medicine says it began in 1972 in San Diego as the clinical practice of Mehlmauer, described as a now-retired Traditional Naturopath, and says sclerology is taught at university level in Brazil. None of these historical claims is detailed in the sources. [source: Grand Medicine Eyology and FAQ pages; Joyful Living Services page] [uncertain: not verified]

Evidence status (one line). No controlled studies of sclerology itself are cited here [uncertain: not verified]; its parent practice, iridology, performed at or near chance in controlled diagnostic studies (Ernst 1999 systematic review; 2026 ophthalmology position paper citing a 2024 Australian NHMRC review), and the sclera-specific claims rest on practitioner observation. [source: Ernst blog summary of the 1999 review; Iuliano, Veritti and Lanzetta 2026]

2. Framework

2a. The method as its organisations publish it

Who practises it. Naturopaths, iridologists and other natural-health practitioners, usually after iridology training. Iridology schools teach it as a supplement to iridology or on its own, and present it as a "second opinion" alongside iridology, electro-acupuncture, kinesiology and lab tests such as RBTI. [source: Academy of Iridology Sclerology 101 page]
What a client experiences. The practitioner examines the whites of the eyes, with a light and magnifier, a hand-held or stand-mounted eye camera (some with chin and forehead rests), or a slit lamp; one school says it can be done "without a camera or any special equipment". Markings are charted against a sclerology map. Grand Medicine teaches "six types of sclera markings" with emphasis on vascular ("line") markings, and sells a guide to "some 82 signs and markings in the sclera and conjunctiva". Findings are summarised and followed by diet, lifestyle, herb and supplement recommendations. Jack Tips' 1995 introduction describes 30 common "stress lines" read as signs of stress patterns, nutritional needs and inherited tendencies. [source: Grand Medicine BASICS course, Signs & Markings Guide, Eyology and FAQ pages; Joyful Living Services page; Goodreads record of Tips 1995]
Diagnosis wording. Grand Medicine calls its data "evaluative", not "diagnostic", and uses non-medical terms (e.g. an "excessively acid tissue condition"), yet also claims to detect problems "up to three years in advance" of symptoms; testimonials call it a "diagnostic tool". One seller states its information "must not be taken as a diagnosis" and that people with medical conditions should see a licensed practitioner. [source: Grand Medicine Eyology and FAQ pages; Joyful Living Services page]
Training and certification. Grand Medicine sells a BASICS course (live, online or recorded; Certificate of Attendance) and an Advanced course (case history, clinical forms, client communication, treatment principles, slit-lamp practicum), and says it has handed Sclerology Competency certification to IIPA. IIPA offers Foundational and Advanced Professional Sclerology certification by exam, only to current members already certified as Comprehensive Iridologists, with annual renewal and continuing-education requirements. [source: Grand Medicine BASICS, Advanced and FAQ pages; IIPA Sclerology page]
Regulation (one line). No statutory licence for sclerology is documented in the US, UK, Canada or Australia; certification is private (IIPA), and scope depends on the practitioner's own licence, if any [uncertain: not verified].
Regulatory status (one line). Not a recognised diagnostic test; the iridology literature recommends it not be used or endorsed for diagnosis or screening. [source: Iuliano et al. 2026]

2b. The psychotherapist's work alongside it [synthesis]

There is no session protocol for this work; it is woven into ongoing therapy. A practical sequence:

Notice and ask (any session): routine inquiry surfaces the reading, a planned reading, or the client's training in it. Move on once it is recorded and understood.
Understand: meaning, hopes, explanatory model, what the client was told, and how it landed emotionally.
Check risk (same session): delayed medical care, symptoms needing a doctor, supplement or diet changes, children, pregnancy, eating-disorder signs, money.
Support decisions and coordinate (where relevant): values-based decision talk; with consent, liaison with the GP, doctor or pharmacist.
Treat what is psychological (as long as clinically indicated): health anxiety, somatic preoccupation, distress about findings, using established approaches (cross-ref Domain II).
Review: revisit at natural points (new reading, new symptom, new protocol).

Move from step 3 to 4 when any risk is present; move to 5 when worry about eye findings or bodily symptoms is persistent, distressing or impairing. Escalate at any point if urgent physical symptoms or safeguarding concerns appear.

3. Guiding principles

[source: APA Ethics Code standards cited where given; otherwise synthesis]

The therapist does not practise or endorse it. Never read eyes, interpret markings, sell charts or courses, or refer for a reading. Practical meaning: the therapist's role is the client's understanding, choices and wellbeing, not the method. [synthesis]
Stay within competence. The therapist cannot judge eye findings or physical health. Practical meaning: route any eye or body question to a doctor or optometrist (APA 2.01 Boundaries of Competence; 2.04 Bases for Scientific and Professional Judgments).
Curiosity without judgement. Practical meaning: ask in a way that makes disclosure easy; a client who feels ridiculed stops telling you. [synthesis]
Attribute, do not adjudicate. Practical meaning: describe sclerology claims as "what the practitioner said", neither confirming them as fact nor mocking them. [synthesis]
Accurate information, client decides. Practical meaning: the client may use sclerology; the therapist ensures choices are informed, especially about not delaying medical assessment (APA 3.10 Informed Consent; 10.01 Informed Consent to Therapy).
Medical safety first. Practical meaning: any new, worsening or alarming symptom, or a change to medicines, goes to the client's doctor or pharmacist; never advise on medicines or supplements. [synthesis]
Do no harm, including by omission. Practical meaning: name risks plainly (missed diagnosis, false alarm, costs) when they arise (APA 3.04 Avoiding Harm).
No commercial entanglement. Practical meaning: no fees, referrals, products or training links with sclerology sellers; disclose and manage any personal connection (APA 3.05 Multiple Relationships; 3.06 Conflict of Interest; 3.08 Exploitative Relationships).
Collaborate with consent. Practical meaning: contact the doctor or pharmacist only with consent, except where law or safety require otherwise (APA 3.09 Cooperation with Other Professionals; 4.05 Disclosures).
Psychological assessment is not eye-reading. Practical meaning: never draw personality or emotional conclusions from a client's eyes, and do not accept a sclerology "emotional" reading as clinical data (APA 9.01 Bases for Assessments).
Children and dependants need extra protection. Practical meaning: a reading must never replace medical assessment of a child; safeguarding procedures apply. [synthesis]

4. Intervention inventory

All interventions below are the psychotherapist's own work alongside sclerology. The sources on sclerology describe no psychotherapy procedures, so the steps are [synthesis] grounded in the method's published features (Sections 1–2) and the APA Ethics Code where cited.

4.1 Routine, non-judgemental inquiry and recording

Purpose / when: Make complementary use discussable. Use at intake and whenever a client mentions natural-health practitioners, iridology, "eye readings", supplements or a new diet.
Steps: (1) Ask a general question about all health approaches, not just sclerology. (2) If a reading is mentioned, ask who did it, when, what tools were used (light, camera, slit lamp), what was said, and what was recommended (diet, herbs, supplements, further readings). (3) Ask whether the client's doctor knows. (4) Record neutrally: date, practitioner type (not the client's private contacts' names unless clinically needed), findings as reported, recommendations, and the client's stance. (5) Return to the session's agenda.
Example language (illustrative): "Many people use approaches outside mainstream medicine. Is anything like that part of how you look after your health at the moment?" / "You mentioned someone looked at the whites of your eyes. What did they tell you?"
Watch for: Embarrassment or defensiveness (normalise, slow down); recommendations that change food, supplements or medicines; any hint that symptoms are being "watched" rather than assessed. Working: the client volunteers updates without prompting.

4.2 Exploring meaning, hopes, expectations and explanatory model

Purpose / when: Understand what sclerology offers the client. Use after disclosure, especially if the client seems invested, frightened or in conflict with doctors or family.
Steps: (1) Ask what drew them (curiosity, feeling unheard by doctors, a wish for early warning, a sense of control, community, identity as a "natural" person, a practitioner they trust). (2) Ask what they hope it will show or do. (3) Elicit their model of their body: the method's own frame says the iris shows inherited tendency and the sclera shows current "stress" or "congestion"; ask what those words mean to them. (4) Reflect the values underneath (prevention, autonomy, being taken seriously). (5) Note how the reading fits with or contradicts medical advice they have had.
Example language (illustrative): "What made you want to have your eyes looked at this way?" / "When they said the lines showed stress in a particular area, what did you take that to mean for you?" / "It sounds like being looked at closely, and listened to, mattered a lot."
Watch for: Distrust of medicine rooted in past bad experiences (validate the experience, not the conclusion); the reading becoming the main source of meaning about the body; spiritual or energy beliefs (the method's own teaching includes etheric and spiritual energies), which are respected as the client's beliefs. Working: the client can name the need the reading meets and other ways that need could be met.

4.3 Working through a reading's findings

Purpose / when: Help a client process what they were told, especially alarming or identity-shaping statements (inherited "weakness", hidden pathology, problems detected "years in advance", emotional or personality conclusions).
Steps: (1) Ask the client to say exactly what was said, in their words. (2) Ask how much they believe it, 0–100, and what feeling comes with it. (3) Separate the statement ("the practitioner said X") from established fact; note neutrally that the organisations call the data "evaluative", not diagnostic. (4) Explore consequences already taken (diet change, worry, checking, avoidance). (5) If the finding concerns a body organ or illness, ask whether the client would like a medical check, and support that step. (6) If the finding was about personality or emotions, explore whether it fits their own experience, without endorsing it as assessment.
Example language (illustrative): "So the person reading your eyes said your liver area showed congestion. On a scale of 0 to 100, how much do you believe that right now?" / "The people who teach this describe it as an evaluation rather than a diagnosis. If you are worried about your liver, would it help to have your doctor check it?"
Watch for: Rising fear, repeated mirror-checking of the eyes, internet searching, or reassurance-seeking (see 4.7); false reassurance ("my eyes are clear, so I don't need the check-up"). Working: belief and distress fall, and the client takes medical questions to a doctor.

4.4 Supporting informed, values-based decisions

Purpose / when: When the client is deciding whether to have readings, follow recommendations, pay for courses or delay medical assessment.
Steps: (1) Clarify the decision in one sentence. (2) List options, including doing both (a reading and a medical check). (3) For each, ask what the client expects, what it costs (money, time, worry), and what could go wrong. (4) Offer accurate information when asked: controlled studies of the parent method, iridology, found chance-level accuracy, and no sclerology-specific studies are cited here. (5) Link to the client's own values. (6) Respect the decision, record it, and agree what would prompt a review. No published decision aid specific to sclerology is cited here [uncertain: not verified].
Example language (illustrative): "What matters most to you in deciding this?" / "If you go ahead with the reading, what would you want to have in place so you don't miss anything a doctor would pick up?" / "It's your call. My only aim is that you're deciding with the full picture."
Watch for: Therapist persuasion (coercion damages trust and autonomy); the client deferring to the therapist; sunk-cost reasoning after paying for courses or protocols. Working: the client can state reasons for the choice in their own values.

4.5 Coordinating with the client's doctor or pharmacist

Purpose / when: Any reading followed by herb or supplement protocols (the Grand Medicine manual includes such protocols), diet change, a stated body finding, or new symptoms.
Steps: (1) Encourage the client to tell their doctor and pharmacist what they take and what they were told. (2) Offer to help them prepare: a written list of products and the reading's findings. (3) With written consent, contact the doctor if there are concerns (delayed care, symptoms, eating-disorder risk). (4) Never advise starting, stopping or changing any medicine, herb or supplement; route those questions to the prescriber or pharmacist (APA 2.01; 3.09). (5) Record consent and contacts.
Example language (illustrative): "Before you start the supplements they suggested, could you show the list to your pharmacist? Some products interact with medicines." / "Would it help if I wrote to your GP, with your permission, so we're all on the same page?"
Watch for: Secrecy from the doctor (explore the fear of being judged); the client asking the therapist to choose between doctor and practitioner. Working: the doctor and pharmacist know what is being taken.

4.6 Recognising and responding to risk

Purpose / when: Every time a reading is reported, and whenever recommendations change.
Steps: Screen briefly for each risk and act:
1. Delayed or replaced medical care: the client is relying on the eyes to judge a symptom, or a "clear" reading is reassuring them out of a check-up. The iridology literature names delayed evidence-based diagnosis and anxiety from false positives as the main harms [source: Iuliano et al. 2026; Ernst summary]. Response: name the risk once, plainly, and support a medical appointment.
2. Eye symptoms: pain, redness that does not settle, yellowing of the whites, or changes in vision belong with a doctor or optometrist, not a reading [synthesis].
3. Supplements and herbs: interaction and toxicity questions go to the pharmacist or prescriber (see 4.5).
4. Diet recommendations: screen for restriction, rigid "clean" eating, weight loss, bingeing or purging. Grand Medicine's site also promotes a liquid diet [source: Grand Medicine Advanced course page links]; if restrictive eating appears, assess for an eating disorder and involve the doctor (cross-ref eating-disorder guidance).
5. Children: a reading or protocol must never replace medical assessment of a child; if a child's illness is going untreated, or the child is put on a restrictive regime, follow local safeguarding procedures. Consider the child's assent and the parents' consent separately [synthesis].
6. Pregnancy: herbs and supplements in pregnancy are for the midwife, obstetrician or pharmacist [synthesis].
7. Money: published prices run to hundreds of dollars per course plus manuals, cameras and protocols [source: Grand Medicine product pages]; ask about spending, debt and pressure to buy.
8. Group or teacher pressure: discouragement of medical care, rhetoric against "Big Pharma" (language appears on the Grand Medicine Advanced course page), loyalty demands, isolation from sceptical family [synthesis].
Example language (illustrative): "I'm glad the reading looked reassuring. A clear reading and a clear medical check aren't the same thing, though. Would you be willing to get that lump looked at too?" / "Has anyone suggested you stop or change anything your doctor prescribed?"
Watch for: Minimising symptoms; secrecy; escalating spending. Working: risks are named, a plan exists, and medical follow-up happens.

4.7 Health anxiety and somatic presentations

Purpose / when: The client repeatedly seeks readings, checks their own eyes in the mirror, photographs their eyes, or is preoccupied by lines and colours as signs of illness. Cross-ref Domain II (health anxiety, somatic symptom disorder).
Steps: (1) Assess pattern: frequency of checking, readings, reassurance-seeking, avoidance, impact. (2) Build a shared formulation: trigger (seeing a red line) → threat interpretation → anxiety → checking or reading → short-term relief → more doubt. (3) Use established health-anxiety CBT components (cross-ref Domain II): monitoring, reducing checking and reassurance-seeking, behavioural experiments, attention training, work on intolerance of uncertainty. (4) Coordinate with the doctor to agree a sensible schedule of medical review. (5) Treat readings as a form of reassurance-seeking only if the client sees it that way; do not ban them [synthesis].
Example language (illustrative): "Each time you look at the lines in your eyes, what happens to the worry over the next hour, and over the next week?" / "What would it be like to try one week without checking, and see what the worry does?"
Watch for: Swapping one form of checking for another; increased distress early in reducing checks (expected, plan for it). Working: less checking, lower preoccupation, more daily functioning.

4.8 When the client trains in or practises sclerology

Purpose / when: The client is a student, iridologist or natural-health practitioner, or considering certification (IIPA requires prior iridology certification, membership and renewal fees [source: IIPA page]).
Steps: (1) Explore what the work means for identity, income and community. (2) If relevant, explore costs of training and certification against income. (3) If the client reports clients of theirs delaying medical care, explore their own scope and ethics, without supervising their practice. (4) If the client asks the therapist to collaborate, refer, or sit for a reading, decline and explain why (see 4.9).
Example language (illustrative): "Becoming certified sounds important to you. What would it give you?" / "I can't take part in readings or refer people, because it sits outside what I do as a therapist, but I'm very glad to keep talking about what this work means to you."
Watch for: Requests for business referrals; dual relationships. Working: the therapeutic frame stays clear.

4.9 Managing the therapist's own boundaries and conflicts of interest

Purpose / when: Always; especially if the therapist has personal interest in natural health, knows the practitioner, or is asked for an opinion on eye markings.
Steps: (1) Never look at or comment on a client's eye markings as health information. (2) No referrals, sales, discounts, affiliate links or shared premises with sellers (APA 3.06 Conflict of Interest). (3) Disclose and manage any personal connection; seek consultation (APA 3.05). (4) Keep personal enthusiasm or scepticism out of the room; the therapist's role is the client's decision process (APA 3.04). (5) Never treat eye appearance as a basis for psychological assessment (APA 9.01).
Example language (illustrative): "I'm not trained to read anything in eyes, and I wouldn't want my opinion to steer you. Let's think about what you want from it."
Watch for: Pressure from the client to "take sides". Working: the client experiences the therapist as neutral and safe.

4.10 Reporting routes

Purpose / when: Misleading health claims, harm from products, practitioners discouraging medical care, or child safeguarding concerns. Discuss with the client and act with consent unless law or safety require otherwise (APA 4.05).
Steps / routes [uncertain: not verified; check current national procedures]:
- Advertising and consumer: US Federal Trade Commission and state attorneys general; UK Advertising Standards Authority and Trading Standards; Australia ACCC and state health complaints commissioners; Canada Competition Bureau.
- Supplements and herbs (adverse effects): US FDA MedWatch; UK MHRA Yellow Card; Australia TGA; Health Canada.
- Professional boards: if the practitioner holds a statutory licence (e.g. naturopath, chiropractor, nurse, doctor), the relevant licensing board.
- Safeguarding: local child or adult protection services following the therapist's own procedures.
Example language (illustrative): "What you were told about not seeing a doctor worries me. There are bodies that look into health claims like this. Would you want to report it, and would you like help doing so?"
Watch for: Client fear of conflict with a valued practitioner. Working: concerns reach the right body, and the client feels supported.

5. Handling problems

The sclerology sources do not address psychotherapy problems; all guidance below is [synthesis] unless a source is given.

Client will not discuss it ("you'll just say it's nonsense"). Acknowledge the expectation, state the stance (curious, not judging, the client decides), and ask permission to return to it later. Do not push. Illustrative: "You've probably had people roll their eyes at this. That's not what I'm here for."
Client asks the therapist's opinion of sclerology. Answer honestly and briefly, without ridicule: the practitioners describe it as evaluative rather than diagnostic; controlled studies of the closely related method, iridology, found it no better than chance [source: Ernst summary; Iuliano et al. 2026]; no sclerology-specific studies are cited here [uncertain: not verified]. Then return to the client's own decision. Illustrative: "Honestly, the research on eye-reading hasn't found it reliable for spotting illness. I'm more interested in what you want to do with what you were told."
Rupture after the therapist raised a medical concern. Name the rupture, take responsibility for how it landed, reaffirm autonomy, and keep the safety message in one sentence. Illustrative: "Last time I think it sounded like I was dismissing something important to you. I'm sorry for that. My worry was only about the symptom, not about you."
Client delays medical care despite discussion (non-adherence to medical advice). Respect capacity and autonomy; record the discussion; agree a "red-line" plan (symptoms that would prompt urgent care); with consent, inform the doctor; revisit. If capacity is in doubt or a dependant is affected, follow capacity and safeguarding procedures.
Overwhelm after an alarming reading. Ground first (breathing, orientation), then separate what was said from what is known, and plan one concrete step (often a medical appointment). Treat ongoing preoccupation as in 4.7.
Stuck in reassurance loops. Repeated questions ("do you think my eyes really show liver damage?") are reassurance-seeking; reflect the pattern rather than answering again, and move to health-anxiety work (4.7; Domain II).
Family conflict. A partner or parent ridicules or forbids readings, or pressures the client into them. Offer a joint session focused on shared values (health, safety, respect), not on settling whether sclerology works.
Financial pressure. Courses, manuals, cameras and protocols accumulate costs [source: Grand Medicine product pages]; explore spending openly, without shame; consider debt advice.
Spiritual or energy framing. Grand Medicine's teaching includes etheric and spiritual energies [source: Advanced course page]. Work within the client's beliefs as beliefs; do not contest them, and do not adopt them as clinical facts.
Client wants the therapist to look at their eyes or photos. Decline warmly and explain the boundary (4.9).
Client's practitioner contacts the therapist. Share nothing without consent; do not exchange referrals; keep any contact to what the client has authorised.
Eye findings that may be real. If the client describes visible eye changes (yellowing, persistent redness, pain, vision change), recommend prompt medical or optometric assessment regardless of the reading.
Children. If a parent relies on readings for a child's symptoms or applies restrictive diets or supplements, discuss directly and follow safeguarding procedures where care is being withheld.
