What is Blepharitis?
Blepharitis is a chronic inflammation of the eyelids. It is a common condition and can occur in both adults and children. Blepharitis can affect the front of the eyelid, where the eyelashes are attached, and the Meibomian glands in the inner eyelid (the moist part that makes contact with the eye) where oily secretions are released to help lubricate the eye.
What causes blepharitis?
The exact cause of blepharitis is unknown. People who suffer from dandruff or dry skin conditions seem more prone. One of the common causes of blepharitis is by an infection of common skin bacteria called Staphylococcus. This affects the glands of the eyelids and eyelash follicles.
Other common causes are:
- eczema-like dermatitis
- scalp dandruff
- an allergic reaction
- acne rosacea
- lice infestation of the eyelids
What are the symptoms?
- ‘something in the eye’ sensation
- itchiness
- excessive tears
- excessive blinking
- sensitivity to light
- crusty or sticky eyelashes
- sore or painful eyelids
- redness and thickening of eyelids
- ulceration
- loss of eyelashes
What is the treatment of blepharitis?
Blepharitis often cannot be completely cured and is an ongoing condition. Regular long-term treatment usually helps to control the symptoms.
The most important factor is to maintain eyelid hygiene.
The eyelid should be cleaned every morning and night for 3-4 weeks until symptoms improve, then twice a week, to maintain eyelid hygiene.
If symptoms return, start daily cleaning again. Products from the pharmacy include baby shampoo, Sterilid and Lidcare.
Do not rub or scratch itchy eyelids as this will worsen the inflammation, use a warm or cold compress.
Contact lenses and eye make-up can further aggravate the condition and should not be worn during treatment.
We may prescribe antibiotic ointment to be used on the lid.
If blepharitis is left untreated, these further eye problems may occur:
- A stye
- A Meibomian cyst
- Conjunctivitis
- Eyelashes turning inwards and rubbing on surface of eye
- Contact lens intolerance
