Ligneous Conjunctivitis

Ligneous conjunctivitis is a rare kind of long-lasting, often-returning “pink eye” where thick, wood-like (“ligneous”) layers—called pseudomembranes—build up on the inner surface of the eyelids (the palpebral conjunctiva). These layers are rich in fibrin, a glue-like protein your body uses to seal wounds. In LC, that fibrin is laid down and not cleared properly, so the layers get firm, yellow-white to red, and woody in feel and look. The condition most often starts in infants and young children, but it can appear at any age. It may also affect other moist linings in the body (mouth/gums, ears, airway, female genital tract, urinary system), not just the eyes. Genetic Diseases Info CenterNCBIHaematologica

Ligneous conjunctivitis (LC) is a very rare, long-lasting type of conjunctivitis where thick, “wood-like” (ligneous) sheets called pseudomembranes keep forming on the inner surface of the eyelids (the palpebral conjunctiva). These sheets are packed with fibrin, the same protein that makes blood clots. LC tends to recur again and again, can scar the eye surface, and can threaten vision if it spreads to the cornea. The problem usually starts in childhood and is often tied to low levels or poor function of plasminogen, the blood protein that normally dissolves fibrin during healing. When plasminogen is too low, fibrin remains, and those hard membranes keep coming back. NCBIPubMed

When the eye’s surface is irritated or injured, the body puts down a fibrin scaffold as part of normal healing. Normally, that scaffold gets cleaned up by an enzyme called plasmin, which is made from a protein called plasminogen. In most people with LC, there isn’t enough working plasminogen (a condition called type 1 plasminogen deficiency), so the fibrin doesn’t get dissolved. It piles up and hardens into those wood-like membranes. Simple everyday triggers like minor infections, rubbing, dust, or small injuries can start this cycle and make it flare again and again. EyeWiki

Types

There isn’t one official, universal “types” list, but in clinics, doctors often talk about LC in these practical categories to guide care:

1. By cause

• Primary (congenital) LC – tied to inherited type 1 plasminogen deficiency due to changes in the PLG gene; this is the classic and most common scenario. EyeWiki

• Secondary (acquired) LC – very rare; LC-like disease appears when plasminogen levels drop later in life (for example with severe liver disease or nephrotic syndrome, both of which can lower plasminogen) and has been reported in adults. The LancetScienceDirectPubMed

2. By extent

• Eye-only LC – lesions limited to the conjunctiva (sometimes the cornea).

• Multisystem LC – similar pseudomembranes also form on other mucous membranes (gums, ear, nose/airway, female genital tract, urinary tract), sometimes causing serious problems such as airway obstruction. Haematologica

3. By age at onset

• Infant/childhood onset (most common) versus adult onset (uncommon but reported). ryplazim.com

4. By location in the eye

• Palpebral (inner eyelid) LC—most common; often upper lid first, then lower lid, and sometimes the bulbar (eyeball) conjunctiva; corneal involvement can occur and worsens outlook. EyeWiki

5. By activity

• Active (membrane-forming) phase versus quiescent/scarring phase (after repeated inflammation).

Causes

Think of these as root causes (that make you prone to LC) and triggers (that kick off or worsen episodes). Not every person has all of these.

Main root causes (biology behind LC):

1. Type 1 plasminogen deficiency (PLGD-1)—inherited, autosomal recessive; the core cause in most patients. (Low plasminogen → poor fibrin cleanup → woody membranes.) EyeWiki

2. PLG gene variants—specific changes in the plasminogen gene that lower plasminogen activity. EyeWiki

3. Secondary/acquired low plasminogen from advanced liver disease (the liver makes plasminogen; severe disease can lower it). ScienceDirect

4. Secondary/acquired low plasminogen from nephrotic syndrome (loss of proteins—including plasminogen—into urine). PubMedPhysiology Journals

Common local triggers (start the flare in a susceptible eye):

1. Minor trauma (rubbing the eyes, grit/dust). EyeWiki
2. Viral or bacterial conjunctivitis (a simple infection can start the wound-healing cascade). EyeWiki
3. Recent eye surgery (e.g., lid, tear duct, or surface procedures). EyeWiki
4. Contact lens irritation or foreign body exposure. EyeWiki
5. Allergic eye inflammation (itching → rubbing → micro-injury), acting as a trigger in someone with low plasminogen. EyeWiki

Whole-body contributors (make fibrin cleanup harder or mucosae more inflamed):

1. Systemic infections (fevers, colds) that coincide with flares in children. EyeWiki
2. Inflammatory states that tip the balance toward less fibrin breakdown. ScienceDirect
3. Severe malnutrition or chronic illness that lowers liver protein output in general (can include plasminogen). (Inference from liver-protein physiology.)

Places where lesions can also form (not causes, but clues to the systemic nature):

1. Gums/oral cavity (ligneous gingivitis)—thick gum overgrowth that bleeds easily. Haematologica
2. Middle ear—recurrent ear issues with pseudomembranes. Haematologica
3. Airway (tracheo-bronchial tree)—hoarseness, noisy breathing; can be dangerous. Haematologica
4. Female genital tract—vaginal/cervical lesions that can affect comfort or obstetric care. Haematologica
5. Urinary tract (renal collecting system)—may cause infections or obstruction. Haematologica
6. Skin (sun-exposed)—rare associations such as juvenile colloid milium. EyeWiki
7. Central nervous system—rare involvement reported in registries. Haematologica
8. Surgical removal of membranes itself—ironically, surgery alone can trigger rapid recurrence because it adds new injury in a low-plasminogen eye; that’s why surgery, if needed, is usually combined with medical therapy. EyeWiki

Symptoms

1. Red eye—often both eyes, but sometimes one first.

2. Stringy/mucoid discharge—sticky, not just watery.

3. Tearing—eyes water more than usual.

4. Soreness or burning—a gritty, irritated feeling.

5. Light sensitivity (photophobia)—bright light hurts.

6. Eyelid swelling—looks puffy or heavy.

7. Visible “membranes”—firm, pale-yellow to red sheets stuck to the inner eyelid that look and feel “woody.” American Academy of Ophthalmology

8. Trouble opening the eye fully—membranes can mechanically limit movement.

9. Blurry vision—from surface irregularity, corneal damage, or discharge.

10. Recurrent pattern—it improves, then comes back after minor triggers. EyeWiki

11. Upper lid favoritism—upper eyelids are often affected first. EyeWiki

12. Foreign-body sensation—feels like something is stuck in the eye.

13. Corneal problems over time—scarring, blood vessel ingrowth, or even perforation in severe cases (these threaten sight). EyeWiki

14. Amblyopia risk in children—if vision stays blurry during visual development. EyeWiki

15. Symptoms outside the eye (when multisystem)—gum overgrowth/bleeding, ear infections, hoarse voice or noisy breathing, genital discomfort. Haematologica

Diagnostic tests

Not every test is needed for every person. Doctors choose based on age, severity, and whether disease is only in the eye or also elsewhere.

A) Physical examination (what the eye doctor sees and measures)

1. Visual acuity testing – simple letter-chart check to see how much the condition is reducing sight.

2. External eyelid inspection – checks lid swelling, crusting, and any skin involvement.

3. Eyelid eversion (single/double) – flipping the lid to look directly at the palpebral conjunctiva where LC membranes usually sit. This is key because LC favors the inner lids, especially the upper lid. EyeWiki

4. Slit-lamp biomicroscopy – a microscope exam that shows color, thickness, attachment, and any blood vessels of the membranes; it also reveals associated corneal changes.

5. Fluorescein staining – a safe dye to highlight surface defects on the cornea that need attention.

6. Intraocular pressure (IOP) check – monitoring is important if steroids are used later; LC itself doesn’t always raise IOP, but treatment can. EyeWiki

B) Manual/office tests (simple, quick, hands-on checks)

7. Photography (standardized) – documenting lesion size and recurrence helps track response to therapy.

8. Color and brightness sensitivity testing – quick functional screens if patients complain of color dullness or glare (helps gauge visual impact).

9. Gentle “true membrane vs pseudomembrane” assessment – LC forms true, adherent membranes; attempts to peel can cause bleeding and should not be done casually in clinic (the point here is recognition, not removal).

10. Tear-film tests (e.g., Schirmer or lissamine green) – not specific to LC, but dryness or surface toxicity can worsen irritation and should be treated.

C) Laboratory and pathology tests (confirming the root problem)

11. Plasminogen activity assay – the key blood test; low functional activity supports plasminogen deficiency. EyeWiki

12. Plasminogen antigen level – measures the amount of plasminogen protein; low amount and low activity fit type 1 deficiency. EyeWiki

13. PLG gene testing – confirms biallelic PLG variants in congenital cases; helpful for family counseling. EyeWiki

14. Histopathology of excised tissue – under the microscope, LC shows an ulcerated surface with sub-epithelial, eosinophilic (pink) fibrin-rich material and immune proteins; special stains help exclude amyloidosis, which can look similar. EyeWiki

15. Basic coagulation panel (PT, aPTT, fibrinogen, D-dimer) – usually not diagnostic of LC, but gives context for bleeding/clotting balance if treatment is planned.

16. Inflammatory markers (CRP/ESR) – general context in flares or infections.

17. Microbiology (swab, culture/PCR) when membranes first appear with obvious infection—helps rule out adenoviral or bacterial causes of membranous conjunctivitis that can look similar early on. (Differential diagnosis is important.) EyeWiki

D) Electrodiagnostic tests (used selectively)

18. Visual evoked potentials (VEP) – if dense membranes or corneal scarring limit a standard retinal exam, VEP checks if the visual pathway conducts signals; helpful in amblyopia risk.

19. Electroretinography (ERG) – rarely needed; used when corneal opacity prevents a good view and doctors need an objective sense of retinal function.

E) Imaging tests (when deeper structures or other sites are involved)

20. Anterior segment OCT/UBM – high-resolution imaging to map thickness and attachment of membranes and to assess corneal involvement and scarring.

21. Airway or sinus imaging (CT/MRI) – only if there are breathing or voice symptoms suggesting pseudomembranes beyond the eye (important because airway lesions can threaten breathing). Haematologica

Non-pharmacological treatments

These are supportive or procedural steps that do not rely on prescription “drug action.” Most work best together with plasminogen-targeted therapy.

1. Gentle debridement of plaques (in clinic or OR)
   Purpose: Relieve discomfort, uncover the eye surface.
   Mechanism: Physically removes fibrin sheets; must be gentle because trauma can trigger regrowth. Works best with immediate adjunct drops to suppress new fibrin. EyeWiki

2. Amniotic membrane transplantation (AMT)
   Purpose: Provide a healing “bandage” layer and reduce inflammation.
   Mechanism: Amniotic membrane supplies anti-inflammatory and anti-scarring factors, supports epithelial growth, and acts as a biologic dressing; often combined with topical agents to prevent recurrence. PMC

3. Bandage contact lens (therapeutic soft lens)
   Purpose: Protect the cornea from rubbing and reduce pain.
   Mechanism: Covers and cushions the surface so the epithelium can heal.

4. Frequent preservative-free lubricating drops/gel
   Purpose: Reduce friction, dilute inflammatory mediators.
   Mechanism: Keeps the surface moist so micro-injuries are less likely.

5. Moisture chamber goggles or night shields
   Purpose: Prevent dryness during sleep.
   Mechanism: Traps humidity, reduces exposure-related irritation.

6. Warm compresses (gentle)
   Purpose: Soften discharge, improve comfort.
   Mechanism: Improves oil gland flow; better tear film stability.

7. Lid hygiene (non-irritating)
   Purpose: Reduce debris and bacteria at the lid margin.
   Mechanism: Lowers inflammatory load without scrubbing the lesions.

8. Allergen and irritant avoidance
   Purpose: Minimize extra inflammation.
   Mechanism: Less histamine and cytokine release means fewer triggers for fibrin build-up.

9. Protective eyewear
   Purpose: Prevent minor trauma (wind, dust, sports).
   Mechanism: Less mechanical injury → fewer flares.

10. Humidifier use at home/work
    Purpose: Reduce dryness that provokes rubbing.
    Mechanism: Keeps environmental humidity adequate.

11. Stop eye rubbing / habit reversal
    Purpose: Cut a major mechanical trigger.
    Mechanism: Prevents micro-trauma that fuels flares.

12. Treat blepharitis/meibomian gland dysfunction
    Purpose: Improve tear quality and reduce irritation.
    Mechanism: Better lipid layer → less evaporation and friction.

13. Nutritional optimization (protein, vitamin C, zinc)
    Purpose: Support wound healing.
    Mechanism: Supplies building blocks for new epithelium and collagen.

14. Smoking cessation / avoid secondhand smoke
    Purpose: Improve surface healing.
    Mechanism: Smoke increases oxidative stress and delays repair.

15. Careful contact lens wear (or temporary pause)
    Purpose: Limit friction and hypoxia during active disease.
    Mechanism: Reduces microtrauma; resume only under medical advice.

16. Oral hygiene and dental care
    Purpose: If gums are involved (ligneous gingivitis), reduce trauma and bleeding.
    Mechanism: Gentle flossing, soft brush, and dental input lower plaque irritation; systemic disease is calmer overall. National Organization for Rare Disorders

17. Voice rest / ENT support when airway involved
    Purpose: Protect laryngeal tissue; prevent airway problems.
    Mechanism: Limits strain and trauma; ENT can monitor for narrowing. National Organization for Rare Disorders

18. Cold compresses for itching
    Purpose: Reduce urge to rub.
    Mechanism: Numbs histamine itch signals; less mechanical damage.

19. Psychological support / coping strategies
    Purpose: Deal with chronic, recurring disease stress.
    Mechanism: Lowers stress-induced behaviors like rubbing; improves adherence.

20. Written “flare plan”
    Purpose: Quick steps at the first sign of a new plaque.
    Mechanism: Early lubrication + faster medical review reduces plaque size and scarring.

Drug treatments

Important: Doses/timing below are typical ranges or label doses where available. Your specialist will personalize therapy and tapering. Always follow your clinician’s plan.

1. Plasminogen (human) IV – Ryplazim®
   Class: Plasma-derived plasminogen replacement (systemic).
   Dose/Timing (label): 6.6 mg/kg IV every 2–4 days to maintain trough levels; for plasminogen deficiency type 1.
   Purpose: Correct the root shortage so fibrin can be cleared body-wide (eyes, mouth, airway, etc.).
   Mechanism: Restores circulating plasminogen → converted to plasmin → dissolves fibrin deposits → fewer new membranes.
   Common side effects: Headache, fatigue, nausea; infusion reactions; “clot-breakdown” effects if on certain medicines (your team will check interactions). U.S. Food and Drug Administration+1Aetna

2. Topical plasminogen eye drops (hospital-prepared or study drug)
   Class: Fibrinolytic biologic (local).
   Typical use: Intensive dosing at first (e.g., hourly to q2–4h), then taper; often used right after gentle membrane removal.
   Purpose: Directly supply plasminogen to the eye surface.
   Mechanism: In-place conversion to plasmin → breaks down fibrin in the plaques; helps stop regrowth.
   Common side effects: Temporary stinging; rare allergy. Evidence from case series/trials supports effectiveness. PubMed+2PubMed+2

3. Heparin eye drops (compounded)
   Class: Anticoagulant (local).
   Use: Several times daily; often combined with plasminogen and/or steroids.
   Purpose: Reduce new fibrin formation on the surface.
   Mechanism: Blocks clotting steps that build fibrin, giving plasmin a chance to clear plaques.
   Side effects: Stinging; small risk of surface bleeding—doctor supervised. PubMed

4. Topical corticosteroids (e.g., prednisolone acetate)
   Class: Anti-inflammatory steroid (local).
   Use: Short courses, tapered; not effective alone for LC but useful with plasminogen/heparin.
   Purpose: Calm inflammation and pain; reduce vascular leakage feeding fibrin.
   Mechanism: Suppresses inflammatory cytokines.
   Side effects: Pressure rise (glaucoma), cataract with prolonged use, infection risk; needs medical monitoring. PubMed

   Class: Antihistamine/MC stabilizer.
   Use: Once or twice daily during itchy seasons.
   Purpose: Reduce itch to stop rubbing.
   Mechanism: Blocks histamine and stabilizes mast cells.
   Side effects: Mild sting/dryness.

10. Oral analgesics / anti-inflammatories (e.g., acetaminophen; NSAIDs if appropriate)
    Class: Pain control.
    Use: Short-term for flares.
    Purpose: Comfort and better eyelid function.
    Mechanism: Central/peripheral pain relief; NSAIDs reduce prostaglandins.
    Side effects: Stomach/bleeding risks with NSAIDs—ask your doctor.

Dietary molecular” and supportive supplements

No supplement cures LC. These support healing and surface health. Discuss with your clinician, especially if you use heparin/anticoagulants.

1. Protein (dietary target 1.0–1.2 g/kg/day if safe): supplies amino acids to rebuild surface cells and collagen.

2. Vitamin C (ascorbic acid 250–500 mg/day): cofactor for collagen cross-linking; antioxidant for wound repair.

3. Zinc (8–15 mg elemental/day): supports epithelial growth and immune balance.

4. Vitamin A (dietary; avoid high-dose pills unless deficient): needed for healthy conjunctiva and cornea (goblet cells).

5. Omega-3 fatty acids (e.g., fish oil 1–2 g/day EPA+DHA if not on blood thinners): anti-inflammatory lipid mediators; may improve tear quality.

6. Vitamin D (per level; often 800–2000 IU/day): immune modulation; supports barrier function.

7. Copper (1–2 mg/day from diet or multi): works with vitamin C for collagen enzymes; avoid excess.

8. B-complex (esp. B2, B6, B12): supports cell turnover and nerve health.

9. N-acetylcysteine (NAC 300–600 mg 1–2×/day): mucolytic/antioxidant; may reduce mucus strands and oxidative stress.

10. L-lysine (500–1000 mg/day): general collagen support (avoid if kidney issues).

11. Probiotics (per product): may ease systemic inflammation via gut-eye axis (early evidence).

12. Turmeric/curcumin (standardized, 500–1000 mg/day with food): natural anti-inflammatory; check drug interactions.

13. Flaxseed or chia (1–2 tbsp/day): plant omega-3 (ALA); supports tear film.

14. Hydration (2–3 L water/day unless restricted): keeps tears less salty; reduces irritation.

15. Avoid high-sugar, ultra-processed foods: spikes inflammation; choose whole foods to support healing.

Regenerative / biologic” therapies

These are specialist-directed and often off-label. They support surface healing and reduce scarring. Evidence is smaller than for plasminogen, but they can help in a plan.

1. Autologous serum eye drops (ASED; 20–50%)
   Dose: 4–8×/day (individualized).
   Function: Supplies growth factors (EGF, vitamin A, fibronectin).
   Mechanism: Mimics natural tears and promotes epithelial repair; not a substitute for plasminogen but may complement it.

2. Platelet-rich plasma (PRP) eye drops
   Dose: often 4–6×/day.
   Function: High platelet growth factors (PDGF, TGF-β).
   Mechanism: Stimulates cell migration and healing; may reduce scarring.

3. Umbilical cord/cord-blood serum drops (where available)
   Dose: specialist protocol.
   Function: Rich in growth factors; used when autologous serum not possible.
   Mechanism: Similar to ASED/PRP; supports re-epithelialization.

4. Amniotic membrane extract eye drops (investigational)
   Dose: per trial/compounding.
   Function: Soluble anti-inflammatory, anti-fibrotic factors.
   Mechanism: Decreases scarring signals; complements AMT.

5. Topical recombinant/plasma-derived plasminogen (clinical-trial or compounded)
   Dose: intensive → taper (specialist).
   Function: Local fibrin clearance.
   Mechanism: Restores fibrinolysis right on the plaque; multiple reports show benefit. PubMed+1

6. Topical tacrolimus/cyclosporine (as a regenerative-supporting immunomodulator)
   Dose: 1–2×/day.
   Function: Reduces chronic immune drive that blocks healing.
   Mechanism: Dampens T-cell pathways; often used long-term to protect surgical grafts/AMT. PMC

Surgeries

1. Careful excision/debulking of pseudomembranes
   Why: Relieve pain, lift mechanical weight from lids/cornea, open the visual axis.
   Notes: Works best with immediate adjunct medical therapy (plasminogen/heparin/steroid), otherwise recurrence is common. EyeWiki

2. Amniotic membrane transplantation (AMT)
   Why: Cover raw surfaces, promote healing, and reduce scarring.
   Notes: May be sutured or glued; often combined with cyclosporine/tacrolimus to protect the graft. PMC

3. Conjunctival autograft or mucous-membrane graft
   Why: Replace damaged tissue if large areas were removed or scarred.
   Notes: Tissue is moved from a healthier site to the damaged site.

4. Limbal stem cell–supportive procedures (for severe surface failure)
   Why: Restore a healthy corneal surface if stem cells are depleted.
   Notes: Rare in LC but considered when the cornea will not re-epithelialize.

5. Temporary tarsorrhaphy (partial lid closure)
   Why: Protect the cornea to heal under a closed or partially closed lid.
   Notes: Reversible; buys time during active treatment.

Prevention tips

Because LC is often genetic, you cannot fully prevent it. But you can reduce flares and damage.

1. Do not rub your eyes.

2. Use preservative-free lubricants often if you are dry or dusty.

3. Wear protective glasses in wind, dust, or sports.

4. Tell surgeons you have LC/PLG deficiency before any eye or ENT procedure.

5. Treat blepharitis/allergies early to cut itch.

6. Avoid smoke and strong chemical fumes.

7. Keep a humid environment at home/work.

8. Have a written flare-up plan from your eye doctor.

9. Maintain good nutrition (protein, vitamin C, zinc).

10. Regular follow-ups with ophthalmology, and with genetics/hematology if you have confirmed plasminogen deficiency.

---

When to see a doctor (and who to see)

• Now/urgent: Severe pain, sudden drop in vision, inability to open the eye, bleeding that won’t stop, signs of airway trouble (hoarseness, noisy breathing) or genital lesions.

• Soon (days): New “woody” plaques, recurrent redness that doesn’t respond to usual drops, or symptoms after recent eye surgery.

• Specialists: Cornea/external disease ophthalmologist (eye surface), plus hematology/genetics for plasminogen testing and systemic therapy. ENT or dentist/periodontist if mouth or airway is involved.

• Ask about plasminogen replacement (Ryplazim) if you have documented type-1 plasminogen deficiency. This is the only FDA-approved systemic therapy for the underlying condition. U.S. Food and Drug Administration

What to eat and what to avoid

1. Eat enough protein (fish, eggs, legumes, lean meats, dairy or soy).

2. Plenty of vitamin-C-rich foods (citrus, guava, kiwi, peppers).

3. Zinc sources (meat, beans, nuts, seeds, whole grains).

4. Healthy fats (olive oil, nuts) and omega-3s (fatty fish, flax, chia).

5. Colorful vegetables and fruits for antioxidants.

6. Hydrate well throughout the day.

7. Limit ultra-processed, high-sugar foods that raise inflammation.

8. Moderate salt to avoid eyelid puffiness for some people.

9. Avoid smoking and excess alcohol—both slow healing.

10. If you use fish oil/turmeric and your plan includes heparin/anticoagulants, ask your doctor (small bleeding risk considerations).

Frequently asked questions (FAQ)

1) Is LC contagious?
No. It is not an infection. It’s a healing problem linked to low plasminogen.

2) Why do the plaques return after removal?
Because the fibrin problem persists. Without plasminogen-based therapy (and careful anti-inflammatory support), the body keeps laying down fibrin, so plaques regrow. Surgery alone is not enough. EyeWiki

3) How do doctors confirm LC?
By examining the plaques, sending a sample to pathology (fibrin-rich), and measuring plasminogen in blood; many cases show type-1 plasminogen deficiency on genetic testing. Orpha

4) What is the best treatment?
The most root-cause approach is plasminogen replacement. For eyes, topical plasminogen (compounded/trial) plus supportive therapy and AMT when needed have good results in reports. Systemically, Ryplazim (IV) treats plasminogen deficiency. U.S. Food and Drug AdministrationPubMedPMC

5) Are steroids enough?
Usually no. Steroids calm inflammation but do not fix the fibrin build-up. They work as add-ons with plasminogen/heparin. PubMed

6) Can LC affect places besides the eyes?
Yes—gums, nose, airway, female genitals, and more. That’s why a whole-body plasminogen plan may be needed. National Organization for Rare Disorders

7) What triggers LC?
Surgery, minor trauma, infections, intense rubbing. Tell all your doctors if you have LC before any procedure. Ajo

8) Will I go blind?
Serious vision loss is possible if the cornea scars, but early diagnosis, plasminogen-based therapy, and eye-surface protection can preserve vision in many people.

9) Is this the same as “membranous conjunctivitis” from bacteria/viruses?
No. Those are usually thin membranes and infectious. LC membranes are thick/woody and due to failed fibrin cleanup.

10) Can children get LC?
Yes. Many cases start in infancy or childhood. Adults can be affected too, especially after eye surgery. BioMed Central

11) Do I need genetic testing?
If your plasminogen levels are low, testing the PLG gene confirms the diagnosis and helps family counseling. Orpha

12) Can I wear contact lenses?
Usually pause during active disease. Later, wear only under your doctor’s guidance, with careful hygiene and lubricants.

13) Are there new treatments coming?
Yes. More work on topical plasminogen formulations and biologic tear substitutes is underway, plus better surgical/medical combos. PubMed

14) How long will treatment last?
LC is chronic. Plans are long-term with tapering and flare-management strategies.

15) Can lifestyle help?
Yes: don’t rub, protect your eyes, treat dryness/allergy, and eat for healing. These steps support (not replace) medical therapy.
