Ligneous Conjunctivitis: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Ligneous Conjunctivitis?
An ophthalmologist, a doctor specializing in eye care and surgery, usually treats this condition. Because the disease is rare, some patients are referred to specialized eye centers. A family doctor or pediatrician can spot the first signs and make a referral.
What it is
Ligneous conjunctivitis is a rare disease that causes firm, woody growths to form on the conjunctiva, the clear tissue lining the eyelids and covering the front of the eye. The growths are made mostly of a blood protein that builds up and hardens. Ligneous means wood-like, because the growths feel firm and look pale yellow or white.
Symptoms
The most common sign is a thick, firm growth on the inside of one or both eyelids. Eyes may feel irritated, red, watery, or like something is stuck in them. Some people notice discharge, and the eyelids may swell. Rarely, similar growths appear in the mouth, throat, or airway.
Causes and who gets it
Most cases happen when the body has trouble with plasminogen, a protein that normally helps dissolve blood clots. When it is missing or does not work well, clots in the eye do not break down, and the woody growths form. Some cases are inherited; others start after an injury, infection, or eye surgery. The disease often begins in childhood, but adults can get it too.
How doctors diagnose it
An eye doctor examines the eyelids and eye surface with a bright light and microscope. The growths have a fairly typical look, but the doctor may take a small tissue sample, called a biopsy. Blood tests or genetic testing may check for a plasminogen problem.
Treatment
There is no single treatment that works for everyone. Doctors often remove the growths surgically, but they usually grow back unless other treatments are added, such as anti-inflammatory drops, drops that dissolve the buildup, or plasminogen eye drops. Treatment takes a long time, and regular follow-up visits help watch for regrowth.
When to see a doctor
Anyone with a firm eyelid growth, long-lasting eye irritation, or thick discharge should see a doctor. Fast care matters if a child has growths in the mouth or throat, because those can affect breathing or eating.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can be a helpful partner, since longer visits make it easier to discuss unusual symptoms. But ligneous conjunctivitis needs an eye specialist, so they would refer the patient to an ophthalmologist and help with follow-up afterward.
Common questions
Is ligneous conjunctivitis contagious?
No. It is not an infection that spreads from person to person. It comes from a problem with a blood protein, an injury, or inherited gene changes.
Does it threaten eyesight?
The growths sit on the eyelid and eye surface. Many people keep good vision with treatment. However, results differ from person to person. Untreated growths can harm the eye surface over time.
Can it be cured?
There is no known cure. The growths often come back after removal. Many people need ongoing treatment and checkups.
Why do the growths look woody?
They are packed with a blood protein that hardens as it builds up. This gives them a firm, pale, wood-like feel that gave the disease its name.
