Blepharoconjunctivitis is an eye condition that’s a combination of two other conditions: conjunctivitis and blepharitis.

Conjunctivitis is inflammation of the transparent membrane that covers the inner part of your eyelid and your eye white. It’s also called pink eye.

Blepharitis is inflammation along the edge of your eyelid.

Bacterial infections or allergic reactions often cause blepharoconjunctivitis. It may be manageable with meticulous eye hygiene alone. If this isn’t enough to treat your symptoms, a doctor may prescribe medicated creams or eyedrops.

Blepharoconjunctivitis can have numerous causes. Its underlying cause is often an infectious disease when the symptoms develop quickly and include ulcers. The most common infectious cause is Staphylococcus bacteria. When the symptoms develop quickly and don’t include ulcers, allergies are most often the cause.

Bacteria can overgrow when the glands in your face secrete too much oil. This oil can cause a buildup of skin cells and bacteria.

Other potential underlying causes include:

People at risk for developing blepharitis include those with:

Blepharoconjunctivitis typically causes eye irritation with a sensation like you have a foreign object in your eye. You may have crusting on your eyelids and the rims of your eyes. Other symptoms can include:

  • swollen and red eyes
  • light sensitivity
  • dandruff on your eyelashes
  • eye irritation or itchiness
  • loss of eyelashes
  • sticky eyelids
  • dry eyes

Symptoms are typically worse in the morning, and it usually affects both eyes.

If left untreated, people with long-term cases of blepharoconjunctivitis may experience complications, like:

  • cornea ulceration and scarring, which can cause vision problems
  • distortion of your eyelids, which can cause:
    • ingrown eyelashes (trichiasis)
    • inward or outward turning of your eyelids
    • a loss of eyelashes

It’s a good idea to visit a doctor if you develop eye symptoms, like light sensitivity or eye pain that doesn’t go away after a few days or causes you distress. It’s especially important if your symptoms don’t improve with home remedies, like washing your eyelids frequently.

It’s also important to see an eye doctor any time you notice changes to your vision, such as blurriness or distortion.

Doctors can usually diagnose blepharoconjunctivitis without needing to order any specific tests. When you visit a doctor, they may:

  • review your personal and family medical history
  • review your symptoms
  • perform a physical exam

They may also perform a film tear breakup test if you have dry eyes. This test involves putting a special dye on your eye called fluorescein and measuring how long it takes for your eye to dry out after your blink.

The main treatment for blepharoconjunctivitis is meticulous eyelid hygiene. You can clean your eyes by:

  1. placing a handful of rice inside a clean sock or cloth and microwaving it for 3 minutes before placing it over your affected eye
  2. gently massaging your eyelids for about 30 seconds
  3. cleaning your eyelids with a cotton ball or applying a small amount of baby shampoo in water to help you wipe away flakes and crusting

It’s a good idea to clean your eyes twice a day. It’s important to keep up this routine even after your symptoms have gone away to keep them from coming back.

If this isn’t enough to manage your symptoms, a doctor may recommend antibiotics, steroid creams, ointments, or eyedrops to kill bacteria.

Artificial tears can also potentially improve dry eye symptoms. One review of studies found that omega-3 supplementation may be beneficial for dry eyes, but research has been mixed, and using omega-3 for this purpose remains controversial.

A combination of petroleum jelly and 1% permethrin shampoo is often effective at treating eyelash lice.

The outlook for blepharoconjunctivitis is usually good and most people can manage their symptoms successfully. It’s important to keep up your eyelid hygiene even after your symptoms go away to keep them from coming back.

A small number of people develop vision problems if they develop scarring on the surface of their eye.

You may be able to minimize your risk of developing blepharoconjunctivitis by washing your face and eyes regularly. It’s also a good idea to avoid applying products around your eye if you’ve had an allergic reaction to one of the ingredients in the product in the past.
