General Structure of Eye History Taking

📝 General Structure of Eye History Taking

1. Patient Details

Name, Age, Gender, Occupation, Address
Referral (self/GP/optometrist/other specialist)

📌 1. Identification

The name uniquely identifies the patient and prevents mixing up with others, especially in hospitals/clinics where many patients may have similar complaints.

📌 2. Record Keeping

For follow-up visits, prescriptions, and reports, the patient’s name is essential.
Helps in tracking medical records, test reports, and surgical notes.

📌 3. Legal & Medicolegal Importance

Medical records are legal documents.
Having the name ensures accountability and accuracy in case of disputes, insurance, or medicolegal cases.

📌 4. Communication & Rapport

Addressing a patient by name builds trust, comfort, and a personal doctor-patient relationship.

📌 5. Research / Audit Purposes

When data is collected (e.g., cataract surgery outcomes), names help in proper categorization and follow-up.

👉 In short: Name = Identification + Record + Legal proof + Personal touch.

📌 Age is Important in Ophthalmology

1. Certain Eye Diseases are Age-Specific

Children 👶

Congenital cataract, Retinoblastoma, Amblyopia, Squint, Congenital glaucoma, Vitamin A deficiency.

Young Adults 👩‍🎓

Refractive errors (myopia, hypermetropia, astigmatism), Contact lens-related issues, Trauma.
Elderly 👵
Cataract, Glaucoma, Age-related Macular Degeneration (AMD), Dry eye syndrome.
2. Guides Examination and Investigations

In a child with squint → rule out amblyopia or retinoblastoma.

In an elderly patient with sudden vision loss → think of vascular occlusion or giant cell arteritis.
3. Treatment Planning Depends on Age

Choice of glasses (progressive lenses for presbyopia).

Type of surgery (e.g., cataract IOL power selection differs in children vs adults).

Medications (children/elderly may need dose adjustment).
4. Prognosis & Risk Factors

Age influences healing and complications.

Children’s eyes heal faster but risk amblyopia if untreated.

Older patients may have comorbidities (DM, HTN) affecting
✅ Summary:
Age helps predict the likely eye disease, guides investigations, influences treatment, and affects prognosis.

📌 Gender is Important in Ophthalmology

1. Certain Eye Diseases Show Gender Predilection

Females

More prone to dry eye syndrome (hormonal changes, menopause).

Higher risk of thyroid eye disease and autoimmune-related eye problems.

Age-related macular degeneration (AMD) more common in women.
Why women (especially after menopause) get dry eye more often:

Tears have 3 layers – water, oil, and mucus.

The oil layer (from meibomian glands in eyelids) keeps tears from evaporating.

Hormones control these glands.

Androgens (male-type hormones) help oil glands work properly.

Women naturally have less androgen than men. After menopause, androgen levels drop even more.
Less oil = faster tear evaporation → eyes feel dry, burning, gritty.

Estrogen changes after menopause can also make the tear film unstable.

Women are also more likely to have autoimmune diseases (like Sjögren’s syndrome) that attack tear glands → severe dry eye.

✅ In short:
After menopause, hormone changes (less androgen, less stable estrogen) weaken the tear glands, so tears dry up faster → dry eye syndrome is more common in women.

📌 Women Have Higher Risk of Thyroid Eye Disease (TED) & Autoimmune Eye Problems
1. Immune System Differences

Women’s immune systems are generally more active than men’s.

This is helpful for fighting infections but makes women more prone to autoimmune diseases (where the body attacks itself).
2. Hormonal Influence (Estrogen & Progesterone)

Female hormones (especially estrogen) stimulate the immune system.

This can increase the risk of the body mistakenly attacking:

Thyroid gland → Graves’ disease / Hashimoto’s thyroiditis

Tear glands & joints → Sjögren’s syndrome, Rheumatoid arthritis
3. Autoimmune Diseases are More Common in Women

Graves’ disease (causes thyroid eye disease) → ~5–6 times more common in women.

Sjögren’s syndrome (causes severe dry eye) → 9 out of 10 patients are women.

Lupus, Rheumatoid arthritis → also much more frequent in women, and both can affect the eye.
4. Thyroid Eye Disease (TED)

In Graves’ disease, the immune system attacks the tissues behind the eyes.

This causes: bulging eyes, lid retraction, double vision, redness, and dryness.

Since Graves’ disease is far more common in women → women get TED more often.
✅ Summary:
Women have a higher risk of thyroid eye disease and autoimmune eye problems because:

Their immune system is naturally more reactive.

Female hormones (especially estrogen) stimulate immunity.

Autoimmune diseases like Graves’ disease, Sjögren’s, RA, and Lupus are much more common in women.
📌Age-Related Macular Degeneration (AMD) is More Common in Women

1. Longer Life Expectancy

Women usually live longer than men.

Since AMD is a disease of old age, more women reach the age where AMD develops → higher numbers of cases in women.
2. Hormonal Changes After Menopause

Estrogen protects the retina (it has antioxidant and anti-inflammatory effects, and improves blood flow to the eye).

After menopause → estrogen levels drop → retina loses this protection → AMD risk increases.
4. Autoimmune & Inflammatory Tendency

Women are more prone to autoimmune and inflammatory responses → inflammation in the retina contributes to AMD progression.

✅ Summary:
AMD is more common in women mainly because they live longer, lose estrogen’s protective effect after menopause, and may have higher inflammatory/autoimmune susceptibility

3. Hormonal Influence

Pregnancy can temporarily change refractive error and worsen diabetic retinopathy.

Menopause → increases risk of dry eye and ocular surface disease.
📌 Hormonal Influence on the Eye

1. Pregnancy

During pregnancy, estrogen and progesterone levels rise a lot.

This causes:

Corneal changes → corneal thickness and curvature increase → glasses/contact lens power may temporarily change → temporary refractive error.

Lens swelling from fluid retention → blurring of vision.
Worsening of diabetic retinopathy → high hormones increase blood flow and vascular changes → in diabetic women, retinopathy can progress faster during pregnancy.
✅ Summary:

Pregnancy hormones → change cornea & lens → temporary refractive error + can worsen diabetic retinopathy.

Menopause hormones → ↓ estrogen/androgens → less tear production → dry eye & ocular surface disease.
Males

Higher risk of ocular trauma (occupational hazards, outdoor work).

Color blindness (X-linked inheritance, affects mostly males).

Keratoconus slightly more common in males.

🟥🟩 Color Blindness is Common in Boys

Color vision genes (for red & green) are on the X chromosome.

Boys (XY):

They have 1 X (from mother) and 1 Y (from father).

If that 1 X has the defective gene → boy will be color blind, because he doesn’t have another X to cover it.
Girls (XX):

They have 2 X chromosomes (one from mother, one from father).

If one X is defective, the other X is usually normal → she can still see colors.

She will be a carrier (can pass it to her children).

Only if both X’s are defective (very rare) → girl becomes color blind.

🌸 Simple Example

Mother = Carrier (Xᶜ X)

Father = Normal (X Y)

Children possibilities:

Son gets Xᶜ from mother + Y from father → Color blind boy.

Son gets X from mother + Y from father → Normal boy.

Daughter gets Xᶜ from mother + X from father → Carrier girl (not color blind).

Daughter gets X from mother + X from father → Normal girl.

✅ That’s why:

More boys are color blind (no backup X).

Girls are usually carriers and rarely color blind.
📌 Keratoconus is Slightly More Common in Males

1. Hormonal Influence

Male hormones (androgens) may influence the cornea’s collagen structure.

This could make the cornea slightly more vulnerable to thinning and bulging in males compared to females.
This could make the cornea slightly more vulnerable to thinning and bulging in males compared to females.
2. Behavioral / Environmental Factors

Eye rubbing is a major risk factor for keratoconus.

Studies show males tend to rub eyes more strongly and frequently (often due to allergies, dust exposure, or habit).

This repeated rubbing weakens the cornea → progression of keratoconus.
3. Genetic & Biological Factors

Keratoconus has a genetic link, but some studies suggest higher penetrance in males.

Male corneas may have differences in enzymes (like matrix metalloproteinases) that make them more prone to corneal thinning.
4. Lifestyle & Exposure

Men are often more exposed to outdoor work, UV light, dust, and trauma, which may increase risk.

✅ Summary
Keratoconus is slightly more common in males mainly due to:

Hormonal differences (androgens affecting corneal collagen).

More frequent/stronger eye rubbing.

Environmental exposures (UV, dust).

Possible genetic & enzyme-related factors.

📌 Occupation is Important in Eye History

1. Exposure to Risk Factors

Different jobs expose eyes to specific dangers:

Farmers / Construction workers → UV light, dust, trauma → pterygium, cataract, injuries

Welders → intense light exposure → photokeratitis (welder’s flash)
Factory / Chemical workers → acid/alkali burns → ocular surface damage

Office workers / IT professionals → prolonged screen use → computer vision syndrome, dry eye
2. Helps in Differential Diagnosis

Miner / Sand worker with eye irritation → think foreign body, chronic conjunctivitis

Textile worker with red eyes → think allergic conjunctivitis

Driver with night vision problems → could be early cataract
3. Treatment & Prevention Planning

If patient is a driver → clear vision is critical → lens prescription / cataract surgery timing is important.

If chemical worker → must advise protective goggles.

If office worker → need ergonomic advice, screen breaks, artificial tears
4. Medicolegal & Compensation Reasons

Some eye diseases are considered occupational hazards (e.g., chemical burns, welder’s flash).

Recording occupation helps in insurance, compensation, and medicolegal cases.

✅ Summary:

Occupation gives clues about the cause of eye problems, helps in diagnosis, guides prevention/treatment, and is important for legal/compensation issues.
📌 Referral Source is Important in Eye History

1. Understanding How the Patient Came to You

Self-referral → patient came directly, may be aware of problem or anxious about symptoms.

GP / Family doctor referral → usually a first-line evaluation has been done.
Optometrist referral → patient may already have glasses/contact lens info, refractive history.

Other specialist referral → may indicate an underlying systemic problem (e.g., endocrinologist for thyroid, neurologist for double vision).
