What is it?

What it is
Ocular rosacea is inflammation affecting the eyelids and eye surface, with or without obvious facial rosacea.

What it is
Bacterial infection of the conjunctiva, the membrane covering the white of the eye and inner eyelids.

What it looks like

Rosacea (Eyes)

Both eyes with red eyelid margins and pinkness across the visible eye surfaces.

Rosacea (Eyes) The eyelid edges and exposed eye surfaces look reddened.

Bacterial Conjunctivitis

A reddened eye with yellow discharge at the inner corner and lower lid.

Bacterial Conjunctivitis A small amount of yellow material collects near the inner corner.

a red left eye with mild lid swelling and a small amount of pale-yellow discharge, viewed with the face turned slightly to the person’s right on deep skin.

In the skin

Inflammation can affect the eyelids and their oil glands. Altered oil secretion destabilizes the tear film and contributes to irritation of the eye surface.

Bacteria trigger inflammation of the conjunctiva, the lining over the eye surface and inside the eyelids. Viral infection and allergy affect the same tissue and can produce similar symptoms.

When it usually starts

Rosacea (Eyes). Can occur at different ages; eye symptoms may precede facial changes.

Bacterial Conjunctivitis. Can occur at different ages depending on the cause.

Causes and triggers

Causes

Inflammation and dysfunction of eyelid oil glands disturb the tear film.

Bacteria inflame the conjunctiva; viral and allergic causes can look similar.

Daily care

Habits that help

Use a warm compress on closed eyelids as advised
Comfortably warm, not hot, compresses help loosen crusts and support oil-gland function.
Clean the lash line gently using the agreed lid-hygiene method
Wash hands first and use a clean pad or cloth for each eye.
Keep up lid care even between flares
A consistent routine is often more useful than vigorous occasional cleaning.
Take screen breaks and reduce airflow across the eyes
Dryness may worsen with infrequent blinking, wind or air-conditioning.
Seek prompt eye assessment for pain, light sensitivity or blurred vision
These symptoms need examination and should not be managed with lid hygiene alone.

Avoid

Avoid: Eye rubbing, irritating makeup and uncomfortable contact lenses
Use glasses during active irritation and discuss when lenses can be resumed.

Habits that help

Wash hands before touching the eyes or using drops
Avoid touching the bottle tip to the eye or lashes.
Use a clean cool compress for discomfort
Use a separate clean pad for each eye.
Clean discharge gently with a fresh damp pad
Do not reuse a soiled cloth or rub the surface of the eye.
Pause contact lenses and eye makeup while symptoms are active
Ask when it is safe to resume lenses and whether equipment needs replacing.
Seek prompt assessment for pain, light sensitivity or vision change
These symptoms are not typical of simple allergy or uncomplicated conjunctivitis.
Follow the prescribed treatment and hygiene plan
Antibiotics are not needed for every red eye; persistent or worsening symptoms need review.

Avoid

Avoid: Sharing eye drops, cosmetics, towels or pillows
This is especially important when infection is possible.

Treatment differences

Evidence labels come from each condition’s own treatment list.

Treatment

● Rosacea (Eyes)

● Bacterial Conjunctivitis

Prescription topicals

None listed

Antibiotic eye treatment when indicated

Listed

A clinician determines whether bacterial infection needs treatment; skin antibiotic creams must not be placed in the eye.

Prescription pills

Eye-clinician treatment

Listed

Persistent or more severe disease may need prescription treatment such as doxycycline in appropriate patients.

None listed

Outlook

Long term

Ocular rosacea can flare repeatedly and may need long-term eyelid care and treatment. Eye pain, light sensitivity or a change in vision needs urgent assessment because the cornea can be affected.

Many uncomplicated cases improve over several days, though the cause and need for treatment should be assessed. Pain, light sensitivity, vision changes or a red eye in a contact-lens wearer needs prompt care.
