Membranous conjunctivitis is a severe form of “pink eye” in which a sheet of tough material (a membrane or pseudo-membrane) forms on top of the moist surface that lines the eyelids and covers the white of the eye (the conjunctiva). This sheet is made from fibrin (a clotting protein), dead surface cells, inflammatory cells, and sticky discharge that “dries” into a layer. The membrane may cling to the tissue. When doctors try to peel it away, the surface can bleed if the attachment is deep.
In simple terms: instead of a watery or sticky film like regular conjunctivitis, the eye grows a “skin-like scab” on the surface. This is the body’s heavy-duty response to intense irritation or infection. Because it is a stronger and deeper reaction than ordinary pink eye, it needs prompt medical attention to protect the cornea (the clear front window of the eye) and to prevent scarring.
How the membrane forms
Trigger: A strong irritant (certain bacteria like Corynebacterium diphtheriae or Neisseria gonorrhoeae, adenovirus, chemicals, autoimmune disease, or severe allergy) injures the conjunctival surface.
Alarm: Injured cells release signals that open blood vessels and pull in neutrophils and other white blood cells.
Fibrin net: The body turns on a clotting response on the inflamed surface. Fibrin weaves a sticky net.
Trapping: Dead cells, bacteria/virus particles, mucus, and immune cells get caught in that net.
Layering: Over hours to days, this net condenses into a membrane.
Attachment depth: If the injury killed the surface epithelium, the fibrin integrates into the raw base and sticks tightly (a true membrane). If the surface remains mostly intact, the sheet sits more loosely (a pseudo-membrane).
Why it matters: a true membrane can tear the raw tissue when removed and may leave ulcers and scars. Even a pseudo-membrane can scratch the cornea, worsen pain, and blur vision.
Types
1) By depth of attachment
True membranous conjunctivitis
The membrane is firmly attached to the underlying conjunctiva. Removal causes bleeding. Classically seen in diphtheria, but also in some severe bacterial, chemical, or immune reactions. Higher risk of scarring and complications.Pseudo-membranous conjunctivitis
The sheet is more superficial, made of fibrin and inflammatory debris. It can often be peeled gently without bleeding, though it may recur until the inflammation is controlled. Seen with adenoviral epidemic keratoconjunctivitis (EKC), severe allergic disease (e.g., vernal or atopic keratoconjunctivitis), ligneous conjunctivitis, and many toxic/irritative injuries.
2) By cause
Infectious: bacterial (including diphtheria and gonorrhea), adenovirus, sometimes herpes.
Non-infectious inflammatory: allergic (vernal/atopic), autoimmune (e.g., ocular cicatricial pemphigoid), Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN).
Toxic/chemical: alkali burns, severe chemical splashes, topical medication toxicity.
Genetic/metabolic: ligneous conjunctivitis (plasminogen deficiency).
3) By timing
Acute: sudden, intense onset with membrane within hours to a few days.
Recurrent/chronic: repeated build-up, often with underlying allergy, autoimmune disease, or ligneous disease.
4) By laterality
Unilateral: one eye (often infectious or local injury).
Bilateral: both eyes (often viral, allergic, systemic, or severe chemical exposure).
5) By severity (practical bedside grading)
Mild: thin pseudo-membrane; minimal pain; vision mostly normal.
Moderate: thicker sheet; photophobia; corneal staining present.
Severe: true membrane; bleeding on removal; corneal ulceration; vision reduced.
Causes
Diphtheria (Corynebacterium diphtheriae)
A toxin-producing bacterium can infect the eye and create a tightly adherent true membrane. Rare where vaccination is common, but dangerous when it occurs.Gonococcal conjunctivitis (Neisseria gonorrhoeae)
A very aggressive bacterium that can cause copious pus, rapid tissue damage, and membranes; a neonatal emergency and also serious in adults.Adenoviral epidemic keratoconjunctivitis (EKC)
Highly contagious viral pink eye that can build pseudo-membranes, severe redness, swelling, and light sensitivity; often spreads in clusters (workplaces, schools, clinics).Severe bacterial conjunctivitis (non-gonococcal)
Streptococci and staphylococci can provoke enough inflammation to form pseudo-membranes, especially if diagnosis or treatment is delayed.Herpes simplex conjunctivitis
Less common as a membranous form, but intense inflammation can deposit fibrin and debris on the conjunctiva.Ligneous conjunctivitis (plasminogen deficiency)
A rare condition where the body cannot break down fibrin normally, leading to wood-like recurrent pseudo-membranes on the conjunctiva (and sometimes other mucosal sites).Vernal keratoconjunctivitis (VKC)
A severe allergic eye disease in children/young adults, often seasonal, with giant papillae and pseudo-membranes from heavy inflammation and rubbing.Atopic keratoconjunctivitis (AKC)
A chronic allergic eye disease in adults with eczema; persistent inflammation can lay down membranes and scar tissue over time.Stevens-Johnson syndrome / Toxic epidermal necrolysis (SJS/TEN)
A severe medication- or infection-triggered immune reaction that strips mucosal surfaces; tight membranes and scarring can threaten vision.Ocular cicatricial pemphigoid (OCP)
An autoimmune attack on conjunctival mucous membranes causes chronic inflammation, membranes, and scarring, leading to dry eye and eyelid malpositions.Alkali chemical burns (e.g., ammonia, lye)
Penetrate deeply and kill surface cells. The healing response lays down fibrin sheets. True membranes can form due to full-thickness epithelial loss.Acid chemical burns
Usually cause more surface-limited damage, but severe cases still trigger membranes as the eye tries to heal.Thermal burns (heat/steam)
Burned conjunctiva mounts a fibrinous reaction, building membranes as part of the “scab” process.Topical medication toxicity (e.g., preservatives, vasoconstrictor overuse)
Chronic irritation from drops (especially with benzalkonium chloride) can injure the surface and lead to pseudo-membranes.Severe contact lens-related inflammation
Hypoxia, poor hygiene, or overwear can inflame the eye so much that fibrin layers develop.Trachoma (chronic Chlamydia trachomatis infection)
Long-standing infection causes repeated inflammation, scarring, and sometimes membrane formation during flares.Foreign body or mechanical abrasion
A lodged or rubbing object can strip epithelium; the repair phase can include fibrin sheets in severe cases.Severe toxic conjunctivitis from cosmetics/chemicals
Strong irritants (certain eyelash glues, hair dyes) can burn the surface and create membranes.Post-surgery inflammation
After eyelid or ocular surface surgery, intense inflammation or infection can lay down membranes until healing stabilizes.Systemic infections with mucosal involvement (e.g., severe streptococcal disease)
Intense systemic inflammatory states can spill over to the conjunctiva and form membranes during the acute phase.
Symptoms
Red eye – the white part looks angry and bloodshot due to dilated surface vessels.
Pain or burning – more ache than typical pink eye, sometimes sharp if the cornea is involved.
Foreign-body sensation – feels like sand or a film is stuck under the lids.
Stringy or thick discharge – mucus or pus that re-accumulates after wiping.
Crusting of lashes – lids stick shut, especially on waking.
Swollen eyelids – lids look puffy, heavy, or droopy.
Photophobia (light sensitivity) – light hurts or dazzles the eyes; patients prefer dim rooms.
Blurry vision – the membrane, discharge, or corneal irritation reduces clarity.
Tearing/watering – reflex lacrimation from surface irritation.
Difficulty opening the eye – the membrane can glue the surfaces together or make blinking painful.
Bleeding spots after membrane removal – a key sign of a true membrane.
Gritty itch – especially with allergic causes like VKC/AKC.
Enlarged preauricular lymph node – a tender “gland” just in front of the ear, common with viral causes.
Fever or sore throat – suggests a systemic infection (e.g., diphtheria, adenovirus).
Headache or general malaise – feeling unwell due to the body’s inflammatory response.
Diagnostic tests
Note: Not every test is needed for every patient. Doctors choose based on the likely cause and severity.
A) Physical examination (at the slit lamp)
Visual acuity (distance and near)
Measures how clearly you see. A drop suggests corneal involvement, heavy membrane, or tear film disturbance.External inspection and eyelid exam
Looks for swelling, redness, skin rashes, and crusting. Gives clues toward allergy, bacterial infection, or SJS/TEN.Slit-lamp biomicroscopy of the conjunctiva
A microscope exam to see the membrane, gauge thickness, check if it’s truly adherent, and look for bleeding points after gentle lifting.Corneal fluorescein staining
A safe dye shows scratches, erosions, or ulcers under blue light. The pattern helps separate mechanical abrasion from infection.Preauricular lymph node palpation
Feeling for a tender node in front of the ear supports a viral cause like adenovirus.Ocular motility and pain with eye movement
Ensures the problem is limited to the surface. Deep pain with movement raises concern for deeper infections (rare but serious).
B) Manual/office procedures
Upper eyelid eversion
Flipping the lid checks for hidden membranes, foreign bodies, and giant papillae (suggests VKC/AKC).Gentle membrane peel under topical anesthesia
Carefully tests how adherent the sheet is. Bleeding on removal = true membrane (often diphtheritic or severe immune injury).Schirmer tear test
Small paper strips measure tear production. Very low values occur in cicatricial diseases or severe allergy with chronic damage.Tear film breakup time (TBUT)
Fluorescein plus stopwatch shows stability of the tear film; short TBUT means unstable surface, common after inflammation.Ocular surface pH test (when chemical burn suspected)
Litmus paper ensures the eye has returned to a safe pH after irrigation (especially vital in alkali injuries).
C) Laboratory & pathological tests
Conjunctival swab for Gram stain and culture
Rapid microscopy plus culture identifies bacteria like gonococcus or strep/staph and guides targeted antibiotics.PCR/NAAT for adenovirus and other viruses
Detects viral genetic material; helpful in outbreaks or severe cases with pseudo-membranes.PCR/NAAT for Neisseria gonorrhoeae and Chlamydia trachomatis
Sensitive tests to confirm gonococcal or chlamydial infection—critical in neonatal and adult high-risk cases.Diphtheria testing (toxigenic culture/PCR; toxin assay)
Confirms C. diphtheriae and whether it produces toxin—key for public health and antitoxin decisions.Conjunctival impression cytology or biopsy
Collects surface cells for microscopy. In ligneous conjunctivitis, shows fibrin-rich lesions; in OCP, direct immunofluorescence may show linear basement membrane antibodies.Blood tests (CBC, CRP/ESR, chemistry; plasminogen levels if ligneous suspected)
Look for systemic infection/inflammation, nutritional or metabolic issues, and plasminogen deficiency.
D) Electrodiagnostic
Visual evoked potential (VEP)
Measures the electrical response from eye to brain. Not routine for conjunctivitis, but in very rare cases with suspected toxin-mediated neuropathy (e.g., severe diphtheria) or unexplained vision loss, it helps confirm that the visual pathway is still transmitting signals.
E) Imaging
Anterior segment optical coherence tomography (AS-OCT)
A non-contact scan that maps membrane thickness, epithelial loss, and corneal edema. Useful to document severity and healing.Ocular ultrasound B-scan or orbital CT (selected severe cases)
If the cornea is too cloudy to see through, B-scan checks the back of the eye. CT orbit is considered only if there’s concern for orbital cellulitis or deep extension in a fulminant bacterial case—uncommon but important to rule out when red flags are present (fever, severe pain with movement, reduced motility).
Non-pharmacological treatments (therapies & “other” care)
Frequent preservative-free lubricating drops/gel/ointment: keeps the surface moist and more comfortable. EyeWiki
Cold compresses 3–4×/day: calms swelling and itching in acute phases.
Stop contact lenses until cleared by your eye doctor; discard disposable lenses/cases used during infection. CDC
Lid hygiene (gentle cleansing): reduces crusts and bacteria on lashes.
Avoid eye rubbing: rubbing worsens inflammation and can hurt the cornea. CDC
Membrane removal in clinic (pseudomembrane): carefully lifting the sheet often relieves discomfort and helps healing. (True membrane removal is controversial because it exposes a raw, bleeding surface.) EyeWiki
Fornix sweeping (adhesion lysis) in acute phase: prevents lids from sticking to the eye surface (symblepharon). EyeWiki
Protective sunglasses / light avoidance: reduces light sensitivity.
Humidifier & blink breaks: supports tear film while healing.

Stay home if contagious (bad viral/bacterial cases with systemic symptoms), to reduce spread. CDC
Strict hand hygiene for patient and family; don’t share towels/makeup. CDC
Dispose of eye makeup & contact lens paraphernalia used during infection. CDC
Cool room and adequate hydration: keeps eyes more comfortable.
Rest your eyes; limit screens during the weepy phase.
Protective eye shield while sleeping if doctor advises (reduces rubbing).
Allergen avoidance if allergy overlays the picture.
Education on contagiousness and cleaning linens (hot wash). CDC
Return checks (3–7 days at first): catches early scarring/infection. EyeWiki
Family/partner testing when an STI-related cause is suspected. PMC

Ways to prevent it
Wash hands often with soap/water (≥20 sec). CDC
Don’t touch/rub your eyes. CDC
Stay home if you have contagious pink eye and feel unwell; follow your clinician’s advice on return to school/work. CDC
Don’t share towels, cosmetics, or eye drops. CDC
Stop contact lens wear during infection; replace disposables and cases after recovery. CDC
Wash pillowcases/sheets in hot water during the contagious phase. CDC
Follow lens hygiene rules strictly in the future. CDC
Vaccinate per schedule (e.g., diphtheria vaccine prevents diphtheria). CDC
Avoid swimming pools while actively infected. CDC
Dispose of eye makeup used during infection; don’t share makeup/brushes. Mayo Clinic
When to see a doctor
Severe pain, strong light sensitivity, or sudden blurred vision.
Thick pus, swelling that’s getting worse, or membranes you can feel.
Symptoms not improving within a week, or worsening at any time.
History of recent high-risk drug reaction (SJS/TEN) or autoimmune disease (OCP/MMP).
Contact lens wearers with marked redness/discharge.
Possible STI exposure, or infants/older adults with significant symptoms. (These situations often require urgent care.) CDC
What to eat (and what to avoid) while you heal
Food can’t “cure” conjunctivitis, but hydration and balanced nutrition support the surface as it recovers.
Helpful choices (10):
Water (regular hydration).
Vitamin A–rich foods (carrots, spinach, kale, eggs) for a healthy surface.
Vitamin C–rich fruit/veg (citrus, berries, peppers) to support healing.
Zinc sources (beans, nuts, lean meat) for tissue repair.
Omega-3–rich fish (salmon, sardines) for general anti-inflammatory support.
Probiotic yogurt if you’re on antibiotics (gut support).
Whole grains; legumes; colorful vegetables; modest coffee/tea.
Best to avoid during the acute phase (10):
Rubbing eyes with food-soiled hands.
Alcohol excess (can worsen dehydration).
Very spicy or salty meals that make eyes feel drier.
Smoking or second-hand smoke (irritates the surface).
Sharing drinks/utensils when contagious.
Supplements without guidance if you’re on other meds (interactions).
“Miracle” eye tonics online—stick with clinician-recommended care.
FAQs
1) Is membranous conjunctivitis the same as “pink eye”?
It’s a severe form of pink eye with a sheet (membrane) on the inner eyelid. Some peel off easily (pseudomembranes), others are “ingrown” and bleed (true membranes). EyeWiki
2) Can I just peel it off at home?
No. Removal should be done by an eye professional. True membranes can bleed and scar if pulled forcefully. EyeWiki
3) Do I need antibiotics?
Only if a bacterial cause is likely—or to prevent infection when the cornea is damaged. Viral cases don’t benefit from routine antibiotics. Medscape
4) Are steroid drops safe?
They can help severe inflammation and reduce scarring—but must be used carefully. In adenovirus they may prolong viral shedding, and they’re dangerous in active HSV epithelial disease without proper antiviral cover. Always follow an ophthalmologist’s plan. PMCNCBI
5) How do doctors decide if it’s viral, bacterial, or something else?
History + slit-lamp exam + targeted swabs/rapid tests/PCR. Severe or unusual cases may need biopsy (e.g., for OCP). EyeWiki+1
6) What if it’s from gonorrhea?
That’s an emergency. Treatment is ceftriaxone 1 g IM once, partner evaluation, and follow-up. Medscape
7) What about diphtheria membranes?
Public-health emergency: antitoxin urgently plus antibiotics; health department and CDC are involved. CDC+1
8) Can membranes cause permanent damage?
Yes—scarring, adhesions (symblepharon), dry eye, keratitis—if not treated promptly. EyeWiki
9) Is it contagious?
Many causes are (especially adenovirus and most bacteria). Good hygiene and staying home when advised reduces spread. CDC
10) Will warm compresses help?
Cold compresses usually feel better in the hot, weepy phase. Warm compresses can help later if lid oils are clogged, but ask your clinician.
11) Do over-the-counter “redness relievers” help?
They may briefly reduce redness but don’t fix the cause and can irritate with overuse.
12) What is ligneous conjunctivitis?
A rare genetic plasminogen deficiency where membranes keep coming back; treatment replaces plasminogen and often uses membrane surgery and adjuncts. EyeWiki
13) Could it be from an allergy or medicine reaction?
Yes—severe hypersensitivity (including SJS/TEN) can form membranes and needs urgent specialist care. EyeWiki
14) Why do doctors sometimes place a “ring” in the eye?
That’s a self-retained amniotic membrane (e.g., PROKERA). It’s a biologic bandage that calms inflammation and encourages regrowth. AAO
15) How soon should I recheck?
Often within 3–7 days initially, sooner if symptoms worsen, to prevent scarring or infection. EyeWiki
