Frequently asked questions (FAQs)

Xerophthalmia is the medical name for eye disease caused by vitamin A deficiency. “Xero” means dry, and “ophthalmia” means a problem in the eyes. When the body does not have enough vitamin A for many weeks or months, the tear film and the surface skin of the eye (conjunctiva and cornea) become unhealthy. The eye becomes dry, rough, and easily infected. Early signs are night blindness and dry eyes. If the shortage is severe or lasts long, the clear front window of the eye (cornea) can soften and melt (keratomalacia), causing ulcers, scars, or even a hole, which can lead to permanent vision loss or blindness. Xerophthalmia is most common where malnutrition is present, especially in young children, pregnant or breastfeeding women, and people with illnesses that reduce vitamin A absorption.

Xerophthalmia means eye dryness caused by not having enough vitamin A in the body. Vitamin A keeps the surface of the eye (the cornea and conjunctiva) smooth, moist, and clear. When vitamin A is low, the glands that make tears slow down, the eye surface becomes dry and rough, and the clear cornea can soften, ulcerate, or even melt (keratomalacia). In children this can move very fast and may lead to permanent blindness if not treated quickly. Xerophthalmia is common where diets lack vitamin A–rich foods (like liver, eggs, dairy, dark-green leafy vegetables, and orange/yellow fruits and vegetables) or during infections (such as measles) and malnutrition. Treatment is urgent high-dose vitamin A, eye surface protection, infection control, nutrition support, and strong prevention in communities (diet, supplements, and measles vaccination).

How vitamin A protects the eye (simple pathophysiology)

Keeps the surface moist: Vitamin A supports goblet cells, which make the mucin layer of tears. Without it, the tear film breaks up quickly and the surface becomes dry and rough.
Maintains healthy skin of the eye: It helps the surface cells mature normally. Deficiency causes “keratinization”—the surface becomes like dry skin, with white foamy patches (Bitot spots) and conjunctival dryness.
Supports night vision: Vitamin A is needed to make rhodopsin in the rod cells of the retina. When levels are low, adapting to darkness becomes slow and difficult (night blindness).
Protects against infection: Vitamin A helps the immune system and keeps barriers intact. Deficiency increases the risk of eye infections and makes corneal ulcers heal poorly.

Types (WHO clinical stages)

XN – Night blindness: Trouble seeing in low light or after sunset. People may stumble in dim rooms or outdoors at dusk.
X1A – Conjunctival xerosis: The white of the eye looks dry and dull, not shiny. Fine wrinkling may be seen.
X1B – Bitot spots: White, foamy, triangular patches on the white part of the eye, usually at the sides (temporal > nasal). They are made of dead keratinized cells mixed with bacteria.
X2 – Corneal xerosis: The cornea begins to look dry, hazy, or matte instead of clear and glossy.
X3A – Keratomalacia (<1/3 of cornea): Softening and ulceration of a small part of the cornea. Pain, light sensitivity, and tearing may be severe.
X3B – Keratomalacia (>1/3 of cornea): A large area of the cornea melts quickly. This is an emergency; perforation and blindness can occur.
XS – Corneal scar: After healing, a white scar remains and may reduce vision permanently.
XF – Xerophthalmic fundus: The retina shows small white or yellowish lesions (thought to be from chronic deficiency). Vision may be mildly affected, especially in the dark.

Causes

Low dietary vitamin A intake: Diets lacking animal sources (liver, eggs, dairy, fish) and not enough provitamin A vegetables/fruits (dark-green leaves, orange/yellow produce).
Food insecurity or famine: Not enough food or lack of variety leads to long-term deficiency.
Early weaning or lack of breastfeeding: Breast milk supplies vitamin A; stopping early increases risk in infants.
Maternal deficiency in pregnancy/lactation: Increased needs; if not met, both mother and baby are at risk.
Measles infection: Measles rapidly depletes vitamin A stores and inflames the eye, raising risk of corneal damage.
Chronic diarrhea or enteric infections: Reduce absorption of fat and fat-soluble vitamins, including vitamin A.
Celiac disease: Damages the small intestine, reducing vitamin A absorption.
Crohn’s disease or intestinal tuberculosis: Inflammation and surgery may limit absorption.
Pancreatic insufficiency (e.g., cystic fibrosis): Not enough digestive enzymes to absorb fat-soluble vitamins.
Cholestatic liver disease (e.g., biliary atresia, primary sclerosing cholangitis): Bile is needed to absorb vitamin A; low bile means poor absorption.
Severe liver disease or alcoholism: The liver stores vitamin A; disease reduces storage and conversion to active forms.
Bariatric surgery (malabsorptive procedures): Reduced intestine length or bypassed segments mean less absorption.
Medications that block fat absorption (e.g., orlistat) or bind bile acids (e.g., cholestyramine): Decrease vitamin A uptake from food.
Long-term use of mineral oil laxatives: Can carry away fat-soluble vitamins.
Very low-fat diets: Not enough dietary fat to absorb fat-soluble vitamins properly.
Zinc deficiency: Zinc is needed for retinol-binding protein and vitamin A metabolism; low zinc worsens deficiency.
Protein-energy malnutrition: Low protein reduces retinol-binding protein, which transports vitamin A.
Parasitic infections (e.g., giardiasis, hookworm): Cause malabsorption and/or chronic blood and nutrient loss.
Prematurity/low birth weight: Limited stored vitamin A and higher needs for growth.
Strict, unbalanced diets or eating disorders: Restrictive patterns without fortified foods or colorful produce.

Symptoms and signs

Night blindness: Hard to see in dim rooms, at dusk, or when entering a dark place from bright light.
Dry eyes (grittiness): Feels like sand in the eyes; blinking does not relieve it.
Burning or stinging: Irritation that worsens in wind, smoke, or air-conditioning.
Red eyes: The surface is inflamed because the protective tear layer is weak.
Stringy mucus discharge: The eye tries to protect itself with thicker secretions.
Photophobia (light sensitivity): Bright light hurts; people may squint or keep eyes closed.
Tearing (paradoxical): Eyes may water because the surface is damaged, even though baseline tear quality is poor.
Blurry vision: Dry, rough surfaces and corneal haze reduce clarity.
Bitot spots: White, foamy patches on the white of the eye (often noticed by others first).
Eye pain: More likely if ulcers or corneal melting occur.
Slow adaptation to the dark: Takes a long time to see after the lights are turned off.
Foreign body sensation: Constant feeling that something is stuck under the eyelid.
Recurrent eye infections: The weakened surface and low immunity invite bacteria.
Corneal ulcer signs: Severe pain, focal white spot, worsening light sensitivity—urgent attention needed.
Permanent reduced vision: From corneal scars or large ulcers that heal with opacity.

Diagnostic tests

A) Physical Exam

History and low-light function check: Ask about trouble seeing at dusk or in a dark room. A simple real-life history often reveals night blindness before any instrument test.
Visual acuity testing (distance and near): Measures how clearly a person sees. Blurring suggests tear film instability, corneal haze, or scarring.
External examination of lids and ocular surface: Looks for redness, dryness, mucus, crusting, lid margin disease, and poor blinking—all common in severe dryness.
Conjunctival examination for xerosis and Bitot spots: With a bright light, the clinician looks for dull, rough conjunctiva and the classic white foamy plaques.
Slit-lamp biomicroscopy (clinical exam): A microscope with bright light shows tear film breakup, punctate epithelial erosions, corneal haze, and signs of ulcers or melting.

B) Manual / Chair-side Tests

Schirmer I test (without anesthesia): A small paper strip is placed in the lower lid for 5 minutes to measure tear quantity. Low wetting suggests aqueous tear deficiency.
Tear film break-up time (TBUT): A drop of fluorescein dye is placed, the patient blinks, and the clinician times how fast dry spots appear. Short TBUT shows unstable tear film due to mucin loss in vitamin A deficiency.
Ocular surface staining (fluorescein and lissamine green): Dyes highlight dead or damaged cells and dry spots on the cornea and conjunctiva. Staining patterns match xerosis severity.
Meibomian gland expression: Gentle pressure on the lid margin checks the oil layer quality. Thick or poor oil worsens evaporation and dryness.
Corneal sensitivity (cotton wisp): Tests the blink reflex and corneal nerve health. Reduced sensitivity suggests surface nerve compromise, a risk for ulcers.

C) Laboratory and Pathological Tests

Serum retinol (vitamin A) level: The key blood test. Low retinol confirms deficiency, though levels can be affected by infection or inflammation.
Retinol-binding protein (RBP): Low RBP supports the diagnosis and helps interpret retinol results when protein status is poor.
Relative Dose Response (RDR) test: Measures the rise in retinol after a small dose. A large rise means liver stores are low (depletion).
Modified Relative Dose Response (MRDR) test: Uses 3,4-didehydroretinol to detect deficiency more specifically. Helpful in surveys and research.
Conjunctival impression cytology: A gentle cellulose acetate filter touches the eye surface to collect cells. Under a microscope, loss of goblet cells and squamous metaplasia support xerophthalmia.
Supportive labs (zinc, protein, liver tests, inflammatory markers): Zinc deficiency, low albumin, liver dysfunction, or high CRP help explain or modify vitamin A results and guide treatment.

D) Electrodiagnostic Tests

Electroretinography (ERG) – scotopic (rod) response: Measures the electrical activity of rod cells in the dark. Vitamin A deficiency usually shows reduced rod responses that improve after treatment.
Electro-oculogram (EOG): Evaluates retinal pigment epithelium function. Abnormal EOG may be seen in significant deficiency and can improve with vitamin A repletion.

E) Imaging Tests

Anterior segment optical coherence tomography (AS-OCT): High-resolution cross-section images of the cornea and tear meniscus. Shows surface irregularity, epithelial thinning, and ulcers.
Fundus photography (and exam): Documents xerophthalmic fundus changes (small discrete lesions) and rules out other retinal disease. Helpful for before-and-after comparisons after treatment.

Dose: single/prolonged placement. Function: anti-inflammatory scaffold to regrow epithelium. Mechanism: heavy-chain hyaluronan, growth factors; reduces scarring.

Surgeries

Temporary tarsorrhaphy: Partially sew eyelids together to protect the cornea. Why: reduce exposure/evaporation; allow ulcers to heal.
Amniotic membrane transplantation: Suture a membrane over the cornea. Why: rapid resurfacing, pain control, anti-scarring.
Conjunctival (Gundersen) flap: Slide vascular conjunctiva over cornea. Why: nourish poorly healing cornea when vision already poor; pain relief.
Lamellar keratoplasty: Replace front corneal layers. Why: repair localized melts/scars.
Penetrating keratoplasty (full-thickness corneal transplant): Replace entire cornea. Why: restore structure and vision after perforation or dense scarring.

Preventions

Eat vitamin A–rich foods weekly (liver once weekly; eggs/dairy; dark-green leaves; orange/yellow veg/fruit).
Add cooking oil to veg meals to absorb carotenoids.
Follow national vitamin A supplementation programs for children/postpartum mothers where indicated.
Measles vaccination for all eligible children.
Treat diarrhea, parasitic infections, and malnutrition early to reduce nutrient loss.
Promote exclusive breastfeeding (first 6 months) and adequate maternal diet.
Use fortified staples (oil, flour, sugar) if available.
Practice eye hygiene and sun/wind protection outdoors.
Limit smoke exposure from cooking or tobacco.
Regular checkups for children with poor growth or frequent infections.

When to see a doctor

Seek urgent care the same day if there is eye pain, light sensitivity, sudden watering, a white spot on the cornea, trouble keeping the eye open, or vision dropping—these can mean ulcer or keratomalacia.
See a clinician within 24–48 hours if a child with measles, severe diarrhea, or malnutrition develops red or dry eyes.
Pregnant patients should avoid high vitamin A doses unless prescribed—ask your doctor for safe alternatives.
Routine visits: children in high-risk areas at vaccination or growth-monitoring visits; adults with chronic dryness every 3–6 months.

What to eat” and “what to avoid”

Eat (daily/weekly rotation):

Liver (small portion once weekly). 2) Eggs (1 daily if allowed). 3) Full-fat dairy (milk, yogurt). 4) Dark-green leaves (spinach, amaranth, kale). 5) Orange/yellow veg (carrot, pumpkin, sweet potato). 6) Orange fruit (mango, papaya, cantaloupe). 7) Fish (esp. oily fish for omega-3). 8) Legumes (lentils/beans) with a little oil. 9) Nuts/seeds (groundnut, sesame). 10) Fortified foods (oil/flour) when available.
Avoid/limit:
Very low-fat diets that block vitamin A absorption. 2) Excess alcohol (hurts liver stores). 3) Ultra-processed snacks replacing nutrient foods. 4) Smoking (oxidative damage). 5) Hot peppers/irritants in the eye area. 6) Rubbing eyes. 7) Direct fan/AC to face. 8) Prolonged screen time without breaks. 9) Dusty/windy exposure without glasses. 10) Unsupervised high-dose vitamin A, especially in pregnancy.

Frequently asked questions (FAQs)

Is xerophthalmia the same as “dry eye”?
Not exactly. Dry eye has many causes. Xerophthalmia is dry eye specifically from vitamin A deficiency, which can rapidly damage the cornea.
How fast can vision be lost?
In children with severe deficiency, corneal melting can occur within days. Quick vitamin A treatment prevents blindness.
What is the life-saving treatment?
High-dose vitamin A given immediately using the WHO schedule (see above), plus eye surface protection.
Can adults get xerophthalmia?
Yes—especially with poor diet, alcoholism, malabsorption (e.g., bariatric surgery, IBD), liver disease, or chronic illness.
Is high-dose vitamin A safe?
It is safe when used short-term under medical guidance for deficiency. Pregnancy needs special caution and usually lower, supervised doses.
Which foods are best?
Liver, eggs, dairy, dark-green leaves, and orange/yellow fruits and vegetables. Eat them with a bit of oil to absorb vitamin A.
Why is measles so important?
Measles drains vitamin A stores and damages the eye surface; giving vitamin A during measles prevents corneal damage and reduces death.
Do eye drops alone cure it?
No. Drops protect the surface, but the root cause is low vitamin A, which needs systemic treatment and nutrition.
What if the child is vomiting?
A clinician can give injectable vitamin A or repeat oral dosing once vomiting stops.
Can I take beta-carotene instead of vitamin A?
For prevention, yes. For emergency treatment, retinyl palmitate/acetate is used because it raises levels fast.
How long until eyes improve?
Pain and light sensitivity often improve in 1–3 days after high-dose vitamin A; full surface healing can take 1–2 weeks or longer if severe.
Will glasses help?
Sunglasses protect from wind/UV. Vision glasses may be updated after the cornea heals if there is scarring or shape change.
What follow-up is needed?
Re-checks at day 1, day 2, and week 2, then monthly until nutrition is stable. Assess growth, diet, and vaccinations.
Is surgery common?
Usually not, if treated early. Surgery is for perforation, deep ulcer, or dense scar (e.g., amniotic membrane, tarsorrhaphy, corneal graft).
Can xerophthalmia come back?
Yes, if diet remains poor or infections recur. Diet improvement, supplements, and vaccination prevent relapse.
