Ligneous Conjunctivitis

What is Ligneous Conjunctivitis?

Ligneous conjunctivitis is a rare form of chronic conjunctivitis in which firm, wood-like, fibrin-rich membranes form mainly on the conjunctiva that lines the inner eyelids.^[1] It is typically associated with type 1 plasminogen deficiency, a genetic disorder of the PLG gene that impairs the body's ability to break down fibrin.^[2] The lesions are part of a body-wide disease, and similar membranes can form on other mucous membranes.^[1]

Common symptoms

The condition begins with red, inflamed patches on the inner eyelid that gradually become thick, fibrin-rich, wood-like membranes.^[2] Redness, irritation and discharge are common, and the membranes can threaten vision. The same disorder can cause lesions in other organs, including the gums, nasopharynx, bronchi, colon, kidney and female genital tract.^[3]

Causes and risk factors

Most cases are caused by plasminogen deficiency, an autosomal recessive disorder, so both parents carry a changed gene.^[4] Without enough plasminogen, fibrin is not cleared, and healing of injured mucous membranes is impaired.^[1] The condition often appears in the first year of life, and chronic inflammation, allergens, infections and minor injury can contribute to flare-ups.^{[2, 5]}

Rare associations include congenital hydrocephalus and, in one report, treatment with a drug that blocks fibrin breakdown.^[1]

How it is diagnosed and treated conventionally

An ophthalmologist usually makes the first assessment, and the distinctive membranes are suggestive. Diagnosis is supported by blood tests of plasminogen activity, a biopsy and genetic testing for the PLG gene.^[2] Because the disease is systemic, coordinated care between the eye specialist and a hematologist is considered important to prevent complications, including vision loss.^[2]

Treatment has historically been difficult, and surgery, topical medicines and plasma-based therapies often gave limited or inconsistent results.^{[2, 6]} An intravenous human plasminogen concentrate is now available. In an open-label trial of 14 patients, all showed clinical success, and most lesions resolved or improved within four weeks.^[3] A long-term study of 12 patients found no new or recurring lesions while they followed the prescribed regimen, and lesions returned when the supply was interrupted.^[6]

Why Ligneous Conjunctivitis calls for a whole-person approach

Ligneous conjunctivitis is not just an eye problem. The underlying plasminogen deficiency affects mucous membranes in several organs, and plasminogen also has roles in wound healing, cell migration and immune and inflammatory processes.^{[4, 7]}

Our role is supportive. We do not diagnose or treat the eye lesions or the plasminogen deficiency, and the condition needs specialist care first.

Fibrin, wound healing and the eye surface

Impaired fibrin breakdown and delayed mucosal healing are the core mechanism.^[1] Treatment that works on this mechanism is medical, such as plasminogen replacement, and is not something acupuncture or herbs can substitute for.^[3]

Inflammation and triggers

Chronic inflammation, allergens, infections and trauma can contribute to flare-ups of lesions.^{[2, 5]} Prompt medical attention to eye infections and injuries is therefore part of good care.

Stress and sleep

Living with a rare, long-term condition that may require repeated infusions and eye care can be stressful, and stress and poor sleep affect everyday wellbeing. No studies were found on this in ligneous conjunctivitis, so supportive care for stress and sleep draws on research in other conditions.

Acupuncture as supportive care in Ligneous Conjunctivitis

What the research shows

No clinical trials of acupuncture for ligneous conjunctivitis or plasminogen deficiency were found in PubMed. We cannot say that acupuncture affects the membranes or the underlying condition.

For a different eye surface problem, a meta-analysis of 21 trials in typical dry eye found better tear film and symptom measures with acupuncture than with artificial tears alone.^[8] Dry eye has different causes, and these results do not apply to ligneous conjunctivitis.

For general sleep difficulties, a review of 24 trials included a meta-analysis of 15 trials suggesting that acupuncture improved sleep quality after three or more weeks compared with medication, with large differences between studies.^[9]

How acupuncture may work

No research explains how acupuncture might affect this condition. Any effect on sleep or stress would be a general effect on the nervous system, not on fibrin or the eye lesions.

What treatment involves

Acupuncture uses fine, sterile, single-use needles placed at selected points, usually left in place for about 20 to 40 minutes. A course usually involves several visits, and we reassess progress with you along the way. Needling on or near the eyelids or eye membranes is not appropriate for this condition, and any needling plan should be discussed with your eye specialist.

Minor reactions such as brief soreness, bleeding or redness at a needle site occur in about 9 in 100 patients, and serious events about 1 in 10,000.^[10] Tell your practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture). Because plasminogen deficiency affects wound healing, tell us about it and about any slow-healing sites.

Ayurvedic medicine as supportive care in Ligneous Conjunctivitis

The Ayurvedic view

Ayurveda has no classical name for ligneous conjunctivitis. Eye diseases with hard growths and discharge are traditionally discussed under eye disorders (Netra roga), with Kapha and Pitta imbalance described as involved. These are traditional frameworks, not biomedical diagnoses.

Therapies that may be used

Traditional supportive care is individualized and may include:

• Dietary and daily-routine advice, with regular sleep and stress-reducing practices
• Breath-based relaxation practices
• Herbs chosen individually by a qualified practitioner after review of your medicines

Traditional procedures applied to the eye or the face are not appropriate for this condition, because anything placed on or near the eye can irritate the membranes or cause injury or infection. Panchakarma is also not appropriate during pregnancy, acute illness or frailty, and it is not suited to this condition.

What the research shows

There are no studies of Ayurvedic medicine for ligneous conjunctivitis. A PubMed search found no trials or case reports. Any Ayurvedic care here is supportive comfort care and not treatment of the eye or the plasminogen deficiency, which is treated medically.^{[2, 3]}

Ayurvedic products also carry quality questions: about one fifth of those bought online contained detectable lead, mercury or arsenic.^[11]

Herbal medicine as supportive care in Ligneous Conjunctivitis

Herbs and formulas that have been studied

No herbs or formulas have been studied for ligneous conjunctivitis or plasminogen deficiency. A PubMed search found nothing relevant.

What the research shows

There is no clinical evidence that herbal medicine affects ligneous conjunctivitis. Because the underlying problem is a missing blood protein that is replaced medically, we do not offer herbs as a treatment for it.^[3] Herbal medicine here is limited to carefully chosen general supportive measures, if any.

Safety and herb-drug interactions

Herbs are active substances. Reviews report herbs and supplements affecting bleeding and clotting, including with warfarin and aspirin, and altering the levels of other drugs.^[12] In a condition of abnormal fibrin breakdown, any herb that affects clotting needs review by your hematologist. Herbal and dietary supplements are also a recognized cause of liver injury.^[13]

Nothing should be placed in or around the eye. Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have liver or kidney disease, or take blood thinners or immunosuppressants.

Translating traditional medicine into modern biological language

This section is interpretation, not equivalence. Chinese medicine might describe a stubborn, thick, discharging eye disorder in terms of dampness, phlegm or stagnation. Modern research instead explains the lesions through reduced plasminogen, impaired fibrin clearance and delayed mucosal healing.^{[1, 2]}

No study has shown that a traditional pattern corresponds to this mechanism, and no study has tested whether treating such a pattern changes the disease.

How this care fits with your medical care

This care is complementary and supportive. Keep your ophthalmologist, hematologist and other physicians, and do not stop or change plasminogen therapy, eye drops or any other prescribed treatment. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care.

Please bring your diagnosis, plasminogen test results, eye reports, your treatment schedule and a full list of medicines and supplements. The disease often begins in infancy, so an infant or child with suspected ligneous conjunctivitis needs a pediatric eye specialist and hematologist first.

When to seek urgent medical care

Ligneous conjunctivitis can threaten vision and has potentially life-threatening complications, so new or worsening symptoms need prompt assessment.^[2]

• Sudden vision changes or loss of vision
• Severe eye pain, or a rapidly growing membrane on the eyelid
• Eye redness with pus, fever or swelling of the eyelids, which can signal infection
• Noisy or difficult breathing, a persistent cough or hoarseness, since membranes can form in the airway
• Heavy bleeding or bleeding that will not stop after surgery or injury
• Lesions that return after a missed or delayed infusion

If any of these occur, call your physician right away, and for an emergency call 911 or go to the nearest emergency department.
