Sclerocornea

Sclerocornea is a rare eye condition that is usually present at birth. In this condition, the clear front window of the eye (the cornea) looks white and opaque, and it blends with the white coat of the eye (the sclera). The normal border between the cornea and the sclera, called the limbus, is hard to see or may be missing. The cornea may also be flatter than normal. Because the cornea loses its natural clarity and natural curve, light cannot enter the eye properly. This reduces vision in a mild way in some children and in a severe way in others.

Sclerocornea is a rare eye condition you are born with. In this condition, the clear front window of the eye (the cornea) looks white and blends into the white coat of the eye (the sclera), so there is no sharp border between them. The cornea may be cloudy only near the outer edge (peripheral sclerocornea) or it may be cloudy across the whole surface (total sclerocornea). When the cornea is cloudy, light cannot pass through normally. This can blur vision, reduce contrast, and in babies it can block the visual signals needed for normal visual development. Sclerocornea is usually non-inflammatory and present at birth. It can happen in one eye or both eyes. In some children it is part of a broader group of developmental changes at the front of the eye called “anterior segment dysgenesis,” and glaucoma and other structural changes can occur along with it. Because the cornea in sclerocornea often has blood vessels and other changes, corneal transplant surgery in these eyes has a more guarded outlook than in other corneal diseases. Early referral to a pediatric cornea specialist and an amblyopia team is very important. EyeWikiPMC

Sclerocornea is not caused by an infection or inflammation in most babies. It is a developmental problem that happens while the baby’s eyes are forming during pregnancy. It may affect one eye or both eyes. It may appear alone or together with other front-of-the-eye problems, such as Peters anomaly, cornea plana (a very flat cornea), Axenfeld-Rieger spectrum (abnormal angle structures and iris), or small corneal size. Sometimes it runs in families. Sometimes it is part of a genetic syndrome that affects more than the eyes. Because it can limit the clear view into the eye, it can also hide other eye diseases. That is why careful examination is important.

In daily life, parents may notice a white or gray front surface in the baby’s eye, frequent tearing, sensitivity to light, eye misalignment, or wandering eye movements. Children with sclerocornea need early and regular care by an eye specialist because early steps to protect vision give the best chance for the child to develop good visual skills.

Types of sclerocornea

1. Peripheral (semicentral) sclerocornea
   The whitening and blending with the sclera involve mostly the outer rim of the cornea. The center may remain clearer. Vision can be better if the center stays clear.

2. Total sclerocornea
   The entire cornea is opaque and looks like sclera from edge to edge. The limbus is not visible. Vision is often severely reduced because light cannot pass through.

3. Unilateral sclerocornea
   Only one eye is affected. The other eye may be normal. Vision problems can still occur due to amblyopia (lazy eye) unless treated.

4. Bilateral sclerocornea
   Both eyes are affected. This is more common than unilateral cases. Vision development needs special attention because both eyes are compromised.

5. Sclerocornea with cornea plana
   The cornea is not only opaque but also unusually flat. A flat cornea reduces focusing power, increases far-sightedness, and causes astigmatism.

6. Sclerocornea associated with Peters anomaly
   There is central corneal opacity and sometimes strands of iris or lens sticking to the cornea. The anterior chamber (front space of the eye) can be shallow.

7. Sclerocornea associated with Axenfeld–Rieger spectrum
   The front angle of the eye and the iris are abnormal. The risk of glaucoma is higher. The corneal border is poorly formed.

8. Isolated (nonsyndromic) sclerocornea
   The corneal problem occurs by itself and there are no clear signs of a broader syndrome.

9. Syndromic sclerocornea
   The corneal problem occurs as part of a wider genetic syndrome that may also affect the face, teeth, heart, kidneys, or growth. A genetics team often helps guide testing and counseling.

Causes and contributors

Sclerocornea is mainly a developmental and often genetic condition. Below are causes and contributors that doctors consider. Some are directly causal; others are well-known associations that guide testing.

1. Sporadic developmental error during eye formation
   Sometimes the cornea does not form correctly in early pregnancy for reasons we cannot identify. This is the most common scenario.

2. Autosomal recessive inheritance
   The change may be passed down when both parents carry one copy of a gene change but do not have the disease themselves. This pattern is more likely in families with consanguinity.

3. Autosomal dominant inheritance
   A single copy of a gene change can be enough to cause anterior segment problems that include sclerocornea in some families.

4. FOXC1 gene variants (anterior segment dysgenesis)
   Changes in this gene can affect the structures at the front of the eye, including the corneal border, and can be linked with sclerocornea-like findings.

5. PITX2 gene variants (Axenfeld–Rieger spectrum)
   This gene helps pattern the front of the eye. Variants can disturb limbal development and may present with sclerocornea features.

6. PAX6 gene variants
   PAX6 is a master eye-development gene. Variants can lead to different front-of-the-eye anomalies, sometimes including corneal opacity and poor limbal formation.

7. FOXE3 gene variants
   This lens-epithelium gene is tied to abnormal anterior segment development and can contribute to corneal opacity patterns similar to sclerocornea.

8. B3GLCT gene variants (Peters plus spectrum)
   This gene change can cause Peters-like findings with corneal opacity, short stature, and other systemic features, and may overlap with sclerocornea presentations.

9. KERA (keratocan) gene variants (cornea plana association)
   Keratocan helps the cornea keep its normal curve. When it is abnormal, the cornea may be very flat and can have sclerocornea-like features.

10. CYP1B1 and other anterior-segment genes (variable contribution)
    Genes linked to front-of-eye development and congenital glaucoma can sometimes be found in children who also show sclerocornea.

11. Axenfeld–Rieger spectrum
    This group of disorders changes the limbus and the drainage angle of the eye. The corneal edge can look like sclera with poor definition.

12. Peters anomaly
    Central corneal opacity with adhesions can coexist with peripheral scleralization, producing a sclerocornea picture.

13. Cornea plana
    Very flat corneal curvature reduces transparency and normal limbal structure, and it often overlaps with sclerocornea clinically.

14. Microphthalmia or small cornea
    A small eye or small cornea can be part of the same developmental pathway and can appear together with sclerocornea.

15. Chromosomal changes or broader genetic syndromes
    Some children have chromosome-level differences that affect multiple organs, including the cornea and limbus.

16. Consanguinity (parents related by blood)
    This raises the chance that a rare recessive gene change comes together in a child, increasing risk of anterior segment anomalies.

17. In-utero exposure to certain teratogens
    Harmful exposures during early pregnancy, such as some medicines or toxins, can disturb eye formation and are sometimes suspected when no gene change is found.

18. Maternal diabetes embryopathy (possible association)
    Poorly controlled diabetes in pregnancy can increase risks of congenital anomalies, and anterior segment differences may occur.

19. Developmental vascularization of the cornea
    Abnormal growth of tiny blood vessels into the forming cornea can prevent it from becoming clear and limbal-shaped, leading to a sclerocornea appearance.

20. Idiopathic cause
    Even after full testing, no single cause may be found. The condition is still real, and vision care is still essential.

Symptoms and signs

1. White or gray corneal appearance
   The front of the eye looks white instead of clear. Parents often notice this in photos or in daylight.

2. Poor red reflex
   When light is shone in the eye, a red glow is weak or absent because the cornea is not transparent.

3. Reduced vision
   Blurry or very poor vision occurs because light cannot focus correctly through the cloudy and often flat cornea.

4. Light sensitivity (photophobia)
   Bright light can be uncomfortable. Children may squint or turn away from light.

5. Tearing and eye watering
   The irritated surface and abnormal shape can trigger more tears.

6. Eye rubbing
   Children may rub their eyes often because the surface feels uncomfortable.

7. Nystagmus (to-and-fro eye movements)
   If both eyes see poorly from early life, the brain may not stabilize gaze, leading to rhythmic eye movements.

8. Strabismus (eye misalignment)
   The eyes may not point in the same direction if one or both eyes have poor image quality.

9. Amblyopia (lazy eye)
   The brain may favor one eye and ignore the other if one eye sees much worse, leading to weak vision development in the ignored eye.

10. Reduced contrast and color perception
    Even when some vision is present, subtle shades and fine details are hard to see.

11. Head tilting or abnormal head posture
    Children may tilt or turn their head to find a position with slightly better vision.

12. Frequent blinking
    Blinking may increase as the child tries to clear their view or reduce glare.

13. Small-looking cornea or unclear limbal border
    The edge of the cornea blends into the sclera, and the cornea can look smaller than usual.

14. Astigmatism and far-sightedness
    A flat and irregular cornea cannot focus light evenly, so glasses prescriptions can be high and complex.

15. Possible pressure-related symptoms if glaucoma coexists
    When the drainage angle is abnormal, eye pressure may rise. Babies may show larger-than-normal corneas, tearing, and light sensitivity; older children may complain of eye pain or headaches.

Diagnostic tests

Goal of testing: We want to confirm the diagnosis, measure how severe it is, look for related eye problems (like glaucoma or adhesions), check for genetic or syndromic causes, and plan safe, helpful treatment to protect vision development.

A) Physical examination

1. Detailed medical, pregnancy, and family history
   The doctor asks about pregnancy health, medication use, family eye history, and whether relatives have similar eye findings. This helps identify inherited patterns and risks for both eyes.

2. Observation of visual behavior
   In babies, the examiner watches whether the child fixes on faces, follows a light or toy, or has nystagmus. This gives a quick, real-life measure of how much the opacity affects vision.

3. External inspection with a light
   The doctor looks closely at the front of the eye with a penlight or torch to see the color, surface, and border of the cornea. A blurred or absent limbus supports sclerocornea.

4. Red-reflex screening
   Using an ophthalmoscope in a dark room, the examiner checks for the orange-red glow from the back of the eye. A weak or missing reflex suggests a cloudy path, such as sclerocornea.

5. Pupil and light-response tests
   The doctor checks whether the pupils get smaller with light and whether both eyes respond equally. Asymmetry may indicate uneven vision between the two eyes.

6. Ocular alignment and nystagmus check
   The examiner looks for eye misalignment or rhythmic movements. These signs point to vision deprivation or unequal vision and guide early amblyopia therapy.

B) Manual tests

7. Age-appropriate visual acuity testing
   Babies may be tested with preferential-looking cards; toddlers with matching picture charts; older children with letter charts. This measures “how well the child sees” with and without glasses.

8. Cycloplegic retinoscopy
   After safe drops temporarily relax focusing, the doctor measures the exact glasses power by shining a light and using lenses. This finds far-sightedness and astigmatism caused by the flat, irregular cornea.

9. Tonometry (eye pressure measurement)
   With a handheld device (such as a Tono-Pen or Perkins), the clinician measures eye pressure. Abnormal angle development can raise pressure, so this test looks for glaucoma.

10. Gonioscopy (angle examination)
    With a tiny mirrored lens at the slit lamp (or under anesthesia for infants), the doctor checks the drainage angle structures. Abnormal bands or closed angles may explain a pressure problem.

C) Laboratory and pathological tests

11. Chromosomal microarray (CMA)
    This blood test looks for small gains or losses of chromosome pieces that can cause syndromes including eye anomalies. It is useful when other body systems are involved.

12. Targeted anterior-segment gene panel
    A blood or saliva test examines several genes known to shape the front of the eye (for example FOXC1, PITX2, PAX6, FOXE3, B3GLCT, KERA, CYP1B1, and others). Finding a variant can confirm cause, guide family counseling, and support screening for related problems.

13. Whole-exome sequencing if panels are negative
    If targeted testing is unrevealing and suspicion remains high, exome sequencing casts a wider net over most protein-coding genes to discover rare or new causes.

14. Pathology of corneal tissue (if a transplant is done)
    When a corneal transplant is performed for vision or clarity, the removed corneal button can be studied under a microscope. It often shows sclera-like collagen, loss of normal corneal layers, and blood vessels, which confirms the diagnosis.

15. Syndrome-directed systemic labs
    Depending on the child’s features, doctors may order blood or urine tests (for example, kidney function tests in suspected renal syndromes or endocrine screening) to look for non-ocular involvement that travels with a particular gene change.

D) Electrodiagnostic tests

16. Flash visual evoked potentials (VEP)
    This test measures the brain’s electrical response to light flashes using small stickers on the scalp. It helps estimate the visual potential when the cornea is too cloudy to judge vision by standard charts.

17. Full-field electroretinography (ERG)
    This test checks how well the retina works by recording electrical signals after light stimuli. If the retina is healthy but the cornea is opaque, results help set realistic goals and plan care.

E) Imaging tests

18. Anterior segment optical coherence tomography (AS-OCT)
    This painless scan uses light waves to build cross-section images of the cornea and the front of the eye. It shows the thickness of the cornea, the shape of the layers, the depth of the anterior chamber, and whether there are adhesions between the iris, lens, and cornea.

19. Ultrasound biomicroscopy (UBM)
    This high-frequency ultrasound looks closely at the hidden front structures even when the cornea is opaque. It helps map a shallow chamber, closed angles, or abnormal strands before surgery.

20. Corneal topography or tomography
    These imaging tools map the corneal curvature and elevation. In sclerocornea they often show a very flat, irregular surface. This information helps choose the best optical correction and set expectations.

Drug treatments

Sclerocornea itself is not “cured” by drops or pills. Medicines are used to (a) protect the surface, (b) control inflammation or infection around surgery, and (c) treat associated glaucoma or rejection risk. Pediatric dosing must be individualized by the treating ophthalmologist. Below I list common agents with class, typical adult dosing patterns to illustrate use (pediatric plans differ), time/purpose, mechanism, and notable side effects.

Dietary molecular supplements

Supplements can support ocular surface and wound healing but do not treat or reverse sclerocornea. Use only under your clinician’s guidance—especially in pregnancy, breastfeeding, and childhood.

1. Vitamin A (prefer food-first)
   Dose (adults, general): Follow RDA; avoid high-dose self-supplementation.
   Function: Epithelial health; severe deficiency can scar the cornea.
   Mechanism: Retinoids support mucin production and epithelial differentiation. PMC

2. Omega-3 fatty acids (EPA/DHA)
   Dose (adults): Often ~1–2 g/day combined EPA+DHA.
   Function: Tear quality and anti-inflammatory support for the surface.
   Mechanism: Modulates inflammatory mediators on the ocular surface (best as part of diet; trial evidence mixed). PMC

3. Vitamin C
   Dose (adults): 500–1000 mg/day commonly used.
   Function: Collagen cross-linking and wound healing.
   Mechanism: Ascorbate is essential for collagen synthesis in corneal stroma. PMC

   Mechanism: Supports DNA/RNA synthesis and epithelial repair.

6. Copper (only if long-term zinc used)
   Dose: ~1–2 mg/day when balancing chronic zinc intake.
   Function: Prevent copper deficiency during zinc therapy.
   Mechanism: Maintains collagen cross-linking enzymes.

7. Lutein + Zeaxanthin (diet-focused)
   Dose: Often 10 mg lutein + 2 mg zeaxanthin/day in adults.
   Function: Antioxidant support; safe for general eye health.
   Mechanism: Concentrated in macula; general ocular antioxidant effect.

8. Protein and essential amino acids
   Dose: Meet age-appropriate protein needs.
   Function: Tissue repair.
   Mechanism: Supplies building blocks for corneal collagen and epithelium.

9. B-complex (esp. B2/riboflavin in diet)
   Function: Mitochondrial enzymes for healing.
   Mechanism: Supports cellular energy for repair.

10. Hydration and electrolytes
    Function: Tear film stability and overall health.

Regenerative / stem-cell–type” therapies

In sclerocornea we do not “boost” the immune system; instead, we modulate it (to protect grafts) and use regenerative biologics to help the ocular surface heal.

1. Topical cyclosporine (0.05–0.1%)
   Function: Immunomodulator for surface inflammation and post-graft quieting.
   Mechanism: Calcineurin inhibition lowers T-cell activity in the cornea/conjunctiva. Lippincott Journals

2. Topical tacrolimus (0.01–0.03%)
   Function: Similar immunomodulatory effect; sometimes used when cyclosporine stings or is inadequate.
   Mechanism: Calcineurin inhibition; potent T-cell suppression locally. BioMed Central

3. Systemic tacrolimus (high-risk grafts only)
   Function: Reduce rejection risk when graft risk is very high.
   Mechanism: Systemic T-cell suppression; trough-guided dosing. Lippincott Journals

4. Systemic mycophenolate mofetil
   Function: Adjunct to reduce immune rejection in selected high-risk pediatric grafts.
   Mechanism: Blocks lymphocyte purine synthesis. Nature

5. Systemic cyclosporine
   Function: Another option in select high-risk cases.
   Mechanism: Calcineurin inhibition systemic effect. PMC

6. Cenegermin (recombinant human nerve growth factor) eye drops
   Function: For neurotrophic keratopathy (if present), to help stubborn epithelial defects heal—sometimes relevant after ocular surgery.
   Mechanism: Supports corneal nerve and epithelial healing; labeled course is 1 drop 6×/day for 8 weeks. NCBIFDA Access Data

Autologous serum or PRP eye drops (from the patient’s own blood) also fit in this “regenerative” sphere and can be combined with other measures under specialist care. ScienceDirectPMC

Surgeries

1. Penetrating keratoplasty (PK; full-thickness corneal transplant)
   Procedure: Remove the central diseased cornea and sew in a donor corneal button.
   Why it’s done: To open a clear optical window when opacity blocks the visual axis.
   Notes: Pediatric PK for sclerocornea has guarded outcomes due to vascularization, glaucoma, and amblyopia; success varies by center and comorbidities. Careful selection and intense follow-up are essential. EyeWikiLippincott Journals

2. Lamellar or deep anterior lamellar keratoplasty (ALK/DALK)
   Procedure: Replace only the diseased anterior layers, keeping the child’s own endothelium.
   Why it’s done: Where opacity is mainly stromal and endothelium is healthy, lamellar surgery can reduce rejection risk and speed rehab.
   Notes: Increasingly considered in children when anatomy allows. PMC+1

3. Optical sector iridectomy
   Procedure: Create an artificial pupil through a clearer peripheral cornea to let light in.
   Why it’s done: When a localized scar blocks the central visual axis and a graft is unlikely to succeed, this can provide useful “ambulatory” vision and support amblyopia therapy. PubMed+1

4. Glaucoma surgery (goniotomy, trabeculotomy, or combined procedures)
   Procedure: Open or bypass the eye’s drainage angle to lower pressure.
   Why it’s done: Control IOP when angle anomalies or glaucoma are present—pressure control protects the optic nerve and the graft. PMCGlaucoma Today

5. Boston keratoprosthesis (KPro) in very select cases
   Procedure: Implant a clear artificial corneal device when grafts are unlikely to survive.
   Why it’s done: For severe bilateral corneal opacity after careful counseling; however, pediatric KPro carries higher complication and failure rates than in adults and is used very cautiously. PubMed

Prevention tips

1. Preconception and prenatal care (optimize maternal health, folate, diabetes control, avoid alcohol and teratogens; follow obstetric guidance).

2. Avoid retinoic acid/isotretinoin in pregnancy unless specifically directed by specialists.

3. Consider genetic counseling where there’s family history of anterior segment anomalies or known syndromes (e.g., 22q11.2). PMC

4. Prompt pediatric eye screening for infants with visible corneal whitening or systemic syndromes.

5. Protect eyes from injury using polycarbonate eyewear in toddlers and children.

6. Maintain routine vaccinations and pediatric visits to reduce severe infections that could complicate eye care.

7. Good hygiene around contact lenses and post-op regimens to prevent infection.

8. Avoid smoke exposure which worsens ocular surface irritation.

9. Balanced diet for mother and growing child to support tissue healing (see “What to eat”).

10. Keep all follow-ups—early detection of glaucoma or graft problems prevents vision loss.

When to see doctors

• Immediately if a newborn’s cornea looks white/cloudy.

• Urgently if pain, light sensitivity, discharge, or a sudden drop in vision occurs at any age.

• Immediately after surgery if the eye becomes very red or painful, vision worsens, or light hurts (possible infection or rejection).

• Promptly if patching/contact lens routines are not tolerated or if patching causes distress or skin breakdown.

• Regularly for pressure checks when glaucoma risk exists.

What to eat” and “what to avoid”

What to eat (general adult guidance; tailor for age with your pediatrician):

1. Colorful vegetables rich in vitamin A precursors (sweet potato, carrots, spinach).

2. Citrus, berries, and peppers for vitamin C.

3. Oily fish (salmon, sardines) for omega-3s; plant sources like flax/chia if preferred. PMC

4. Eggs and leafy greens for lutein/zeaxanthin.

5. Lean proteins (pulses, poultry, fish) for tissue repair.

6. Nuts, seeds, legumes for zinc (and balance with trace copper via varied diet).

7. Dairy or fortified alternatives for vitamin D and calcium, as appropriate.

8. Plenty of water for tear film hydration.

9. Whole grains for steady energy and micronutrients.

10. For infants: breastmilk or appropriate formula per pediatric guidance; no supplements unless prescribed.

What to avoid or limit:

1. Unsupervised high-dose vitamin A or any megadose supplements in pregnancy/childhood. PMC

2. Alcohol and known pregnancy teratogens; follow obstetric advice.

3. Tobacco smoke exposure.

4. Highly processed, salty snacks that worsen dehydration.

5. Contact lens wear in unsafe settings or without hygiene.

Frequently asked questions

1) Is sclerocornea an infection?
No. It is a developmental condition present at birth. The cornea looks white because it did not form its usual clear layers, and blood vessels can grow into it. It is not caused by germs and is not contagious. EyeWiki

2) Can eye drops cure sclerocornea?
No. Drops can comfort the surface, prevent infection around surgery, control inflammation, or lower eye pressure if glaucoma is present, but they cannot make an opaque cornea clear. Surgery or optical bypass is needed when the visual axis is blocked. Medscape

3) Is a corneal transplant always the answer?
Not always. In sclerocornea, transplants in children have a guarded prognosis due to blood vessels, glaucoma, and high rejection risk. Some children do better with lamellar procedures or an optical iridectomy if a clear peripheral window exists. Decisions are individualized. EyeWikiPMC

4) What is the biggest risk to vision early on?
Deprivation amblyopia—when a cloudy cornea blocks visual signals during the brain’s “wiring” period. That is why early optical strategies and amblyopia therapy are crucial. Medscape

5) Can special contact lenses help?
Yes. Rigid or scleral lenses—including PROSE devices—can create a smooth optical surface and protect fragile epithelium in selected cases, even in children at experienced centers. EyeWikiBostonSight

6) Is glaucoma common with these front-of-eye problems?
Glaucoma can occur in the broader group of anterior segment dysgenesis conditions, which may accompany sclerocornea. Lifelong monitoring is needed because pressure damage can silently steal vision. ResearchGate

7) Are there medicines I should avoid in small children?
Yes. Brimonidine is not recommended under 2 years because of reports of central nervous system depression. Timolol and other topical beta-blockers can cause systemic effects in infants and must be used cautiously and only under specialist care. PubMedAAP Publications

8) Do “immune boosters” help?
There is no “booster” to reverse sclerocornea. In fact, for high-risk grafts, doctors sometimes calm the immune system with agents like tacrolimus or mycophenolate to protect the transplant. Lippincott Journals

9) What is cenegermin and does it apply here?
Cenegermin is a lab-made nerve growth factor drop for neurotrophic keratitis. It can help persistent epithelial problems after surgery, but it does not treat the congenital opacity itself. NCBI

10) If transplantation fails, is there any other option?
In very select cases, doctors may consider a Boston keratoprosthesis, but in children it carries higher complication and failure rates than in adults and is used with great caution. PubMed

11) Can nutrition fix sclerocornea?
No. Nutrition supports healing and general eye health, but it does not clear a congenitally opaque cornea. Still, a balanced diet helps recovery and surface health. PMC

12) Is sclerocornea genetic?
It can be sporadic or inherited. Some families show links to genes involved in corneal development or to syndromes such as 22q11.2 deletion syndrome. Genetic counseling can help families understand risks. PMC

13) If only one eye is affected, should we still treat aggressively?
Yes—because amblyopia can still develop. However, surgeons may weigh the risk–benefit of grafting a single affected eye more cautiously when the other eye sees well. PMC

14) How fast must we act?
Promptly. The first months and years are critical for visual development. Early optical access to a clear pathway and amblyopia therapy improve the chance of useful vision. Medscape

15) What outcome can we expect?
Outcomes vary widely and depend on how much of the cornea is involved, whether glaucoma or other anomalies exist, the type/timing of surgery, and how rigorously amblyopia therapy is followed. Many children achieve functional or ambulatory vision; some reach better levels after successful surgery and rehabilitation. Lippincott Journals
