How ocular pemphigoid affects the eye
Mucous membrane pemphigoid is a rare autoimmune disease. The immune system attacks the moist linings of the body, such as the mouth, nose, throat, and eyes. When it involves the eyes, it is called ocular mucous membrane pemphigoid, or ocular cicatricial pemphigoid (“cicatricial” means scarring). It causes a long-lasting conjunctivitis in both eyes that flares and settles over time. Ocular disease accounts for about 60% to 70% of people with mucous membrane pemphigoid.[1] In a US clinic that followed 162 people with biopsy-proven disease, 67% already had eye involvement when they were first seen.[4]
The damage comes from scarring of the conjunctiva, the thin membrane that lines the inside of the eyelids and covers the white of the eye. As it scars:[1][2][5]
- The pocket under the eyelids gets shallower. Bands of scar tissue, called symblepharon, can tether the eyelid to the eyeball.
- The eyelids and lashes turn inward. Inturned lashes (trichiasis) and inturned lids (entropion) were the most common findings in a review of 35 studies.
- The eye gets dry. Dry eye is one of the problems that makes the disease hard to live with and hard to manage.[6]
- The cornea suffers. Over time the cornea (the clear front window of the eye) can grow blood vessels, cloud over, and develop wounds that won’t heal. Left untreated, this can lead to permanent vision loss.
The disease is often slow to be recognized. In a UK-wide surveillance study, ocular pemphigoid accounted for 61% of new cases of scarring conjunctivitis, at about 0.8 new cases per million people each year. The median time from first symptoms to diagnosis was 225 days. At diagnosis, 62% of eyes already had symblepharon, and the number of scar bands kept rising over the following year even when inflammation was controlled.[3] That is why early referral to a specialist in eye inflammation or cornea disease matters so much.
Treatment of the disease itself is medical. Because the scarring is driven by the immune system, treatment aims to control that inflammation, usually with medicine that calms or suppresses the immune response, prescribed and monitored by a specialist.[2] In the UK study, 52% of patients were started on immune-suppressing treatment or had it changed.[3] Nothing on this page replaces that care.
How a scleral lens helps a pemphigoid eye
A scleral lens is a large rigid gas-permeable lens. It rests on the sclera (the white of the eye) and arches over the whole cornea without touching it. Before it goes in, the lens is filled with sterile, preservative-free saline, so a pool of fluid sits against the cornea for as long as the lens is worn.
For an eye with pemphigoid, that does three things:
- It keeps the cornea wet. When the tear film can no longer protect the surface, the saline reservoir keeps the cornea bathed all day.
- It shields the cornea from the eyelids. Scarred, inflamed lids rub a dry cornea with every blink. With the lens in place, the lids move over the smooth lens instead.
- It can sharpen vision. The smooth lens surface and fluid layer mask an uneven or scarred cornea.
The lens is a support for the eye surface, not a treatment for the disease. Inturned lashes still need treatment by your eye doctor, and inflammation still needs medical control. In the published reports, scleral lenses were used alongside systemic and topical treatment, not in place of it.[7][6]
What the research shows
The evidence is small. There are no randomized trials. What exists is one retrospective clinic series, a few case reports, and mixed series of severe surface disease that include some patients with pemphigoid. Treat the results as encouraging rather than settled.
The largest series is from one US clinic. Researchers at Emory University reviewed 20 patients (36 eyes) with ocular pemphigoid fitted with scleral lenses and followed for an average of 16.5 months. Lenses were worn about 9 hours a day, and overnight wear was not allowed. Every patient reported better comfort. Average vision improved, and 46% of eyes gained two or more lines on the eye chart. Damage to the corneal surface became milder on average. At last follow-up, 96% of eyes were still wearing their lenses. Scarring signs that were present at the start, such as shallow fornices, symblepharon, and inturned lashes, stayed stable during follow-up.[6] That study wasn’t designed to show whether the lenses themselves slowed scarring, so it shouldn’t be read that way.
Case reports describe healing of stubborn corneal wounds. At the Mayo Clinic, a 74-year-old woman with pemphigoid had corneal wounds in both eyes that hadn’t healed despite aggressive treatment. Within six weeks of starting scleral lenses the wounds closed, and further thinning of the cornea stopped. Vision in one eye improved from 20/150 to 20/50.[7] A similar report from India described a 68-year-old man whose corneal wounds healed within four weeks of starting mini-scleral lenses, alongside his immune-suppressing treatment.[8] Single cases show what is possible, not what is typical.
Pemphigoid appears in broader series too. A Boston series of 49 patients with severe ocular surface disease included ocular pemphigoid among its indications, though most eyes in it had Stevens-Johnson syndrome. Across the whole group, 53% of eyes gained two or more lines of vision, and 92% of patients reported better quality of life. Many patients had preparatory procedures before fitting, such as closing the tear drainage ducts or grafting membrane tissue.[9]
Other options, compared
Scleral lenses usually sit alongside other treatments. Your specialist decides the overall plan.
| Option | What it does | Typically suited to |
|---|---|---|
| Systemic immune-suppressing or anti-inflammatory medicine | Calms the immune attack that drives scarring | Active ocular pemphigoid; chosen and monitored by a specialist |
| Preservative-free lubricants | Support a damaged tear film | Everyone with ocular pemphigoid, as a base layer |
| Treatment of inturned lashes or lids | Removes or redirects lashes and repositions the lid | Trichiasis and entropion |
| Bandage soft contact lenses | Cover the cornea short term to help it heal | Short-term protection of a corneal wound |
| Scleral lenses | Hold a saline reservoir over the cornea and shield it from the lids | Dryness, surface damage, or poor vision despite other treatment |
| Ocular surface surgery | Releases scar bands or reconstructs the eye surface | Advanced scarring; usually timed around disease control |
Questions to ask a scleral lens fitter
- How many patients with ocular pemphigoid or scarring eye disease have you fitted?
- Will you share your notes with the specialist who manages my pemphigoid?
- Does the scarring in my eyes affect whether a lens will fit, and might I need any procedure first?
- How often will you check my eyes for infection or signs that the lens is pressing on scarred tissue?
- What cleaning routine do you recommend while I’m on immune-suppressing medicine?
- Can a family member learn to put the lenses in and take them out?
- What should I do if my eye becomes red or painful while I’m wearing the lens?
Common questions
Can a scleral lens stop ocular pemphigoid from getting worse?
No. Pemphigoid is an autoimmune disease, and the scarring is driven by inflammation that needs medical treatment, usually medicine that suppresses the immune system. A scleral lens protects the cornea and can improve comfort and vision. It works alongside that treatment, not instead of it.
Is ocular pemphigoid the same as ocular cicatricial pemphigoid?
They describe the same disease. Ocular cicatricial pemphigoid is the older name. Mucous membrane pemphigoid is the broader disease, which can also affect the mouth, nose, throat, skin, and other areas. When it affects the eyes, many specialists now call it ocular mucous membrane pemphigoid.
Can I sleep in my scleral lenses?
Not unless your doctor specifically tells you to. In the largest published study of scleral lenses for ocular pemphigoid, overnight wear was not allowed. Overnight wear is sometimes used for a short time to heal a wound on the cornea, but only under close supervision.
What happens if my eye gets red or painful while I'm wearing the lens?
Take the lens out and call your eye doctor the same day. Your eye is fragile and you may be on immune-suppressing medicine, so an infection needs to be ruled out quickly. Don't put the lens back in until you've been seen.
Will I need anything done before a scleral lens fitting?
Some people need preparation first. In one published series of scleral lenses for severe surface disease, which included pemphigoid, many patients had procedures before fitting, such as closing the tear drainage ducts or grafting membrane tissue onto the eye surface. Your fitter and eye doctor will decide whether a lens is practical for your eye.
