Blepharitis

What is blepharitis?

Blepharitis is an inflammation of the eyelids and is very common. Blepharitis usually affects both eyes on the edge of the eyelids and although rarely serious, it can be an uncomfortable, persistent and irritating problem.

People who suffer from blepharitis often report dry, sore or red eyes. Sometimes, blepharitis can cause a burning or itching sensation, or the feeling that something is in your eye. Some people may also notice crusty or greasy debris around their eyelashes.

Your optometrist can determine if you have blepharitis by examining your eyes with a special microscope (called a slit lamp). Careful assessment of your eye surface, tear film and eyelid margins allows your optometrist to classify the kind of blepharitis present. By knowing the type and cause of blepharitis, the right treatment plan and care regime can be drawn up for you.

Classification of blepharitis

Blepharitis can be subdivided into three groups. Often there is significant overlap of signs and symptoms among the groups.

Seborrheic Blepharitis

Seborrheic is just a technical term for "oily", so this kind of blepharitis is associated with overactive sebaceous (oil) GLANDS. People with Seborrheic blepharitis also often have dandruff of the scalp, asthma, hay fever, allergies or a skin condition called acne rosacea.

Infective Blepharitis

Infective blepharitis is often caused by staphylococcus, a type of bacteria that is normally found on the skin around your eyes. Reduced immune function may allow staphylococcus to set up an infection on the eyelids, resulting in crusty deposits and sticky tears.

Meibomian Gland Dysfunction

The Meibomian glands are in the back of the eyelids and usually responsible for secreting and oily substance that forms part of the normal tear film. If the glands are not functioning properly and start producing a secretion that is too thick, they will become clogged. As a result, the eyelids can become inflamed and more susceptible to infection.

Causes

Blepharitis can be associated with a skin condition such as acne rosacea (oil gland malfunction) or a bacterial infection (staphylococcus). Sometimes eye make-up can cause blepharitis be initiating an allergic reaction that results in swelling of the eyelids and defective tear formation.

Treatment

If the cause of blepharitis is cosmetic, cessation of use of the offending makeup may be all that is required. Blepharitis is more commonly a long term condition requiring ongoing maintenance. Usually, a simple care regime is all that is required to prevent or reduce the severity of future bouts.

Your cleaning regime

Treatment can include applying daily warm compresses (a clean, warm washcloth) to soften the oily, sticky or crusty substance on the eyelids. Cleansing is the next step and is an essential part of blepharitis treatment. Your optometrist will recommend the solution to use: warm water only, salt water, diluted baby shampoo or special over the counter lid cleansing products.

The solution can be gently massaged into the eyelids and lashes using a clean finger or cotton bud, as advised by your optometrist. Always wash your hands before handling the eyelids.

If eye drops or ointment are necessary, they will be prescribed when the condition is first diagnosed. Drops or ointment should be applied after both the warming and cleansing steps.

Your optometrist may also recommend lubricating eye drops and vitamin supplements to promote ongoing ocular health and comfort.

Prevention

If you are susceptible to blepharitis, conscientious eyelid hygiene can help prevent a recurrence.

  • Always wash your hands before touching your eyelids.
  • Wash your hair and face daily.
  • Wash your eyelids nightly.
  • Avoid cosmetics.

A regular consultation with your optometrist will prevent untreated conditions becoming worse.
