Blepharitis

Causes and Risks:
Blepharitis has multiple causes but is usually caused by seborrheic dermatitis , a bacterial infection, or a combination of both, allergies , or infestation with lice (in the eyelashes). Blepharitis is characterized by excess oil production in the glands near the eyelid, which creates a favorable environment for the growth of bacteria. Eyelids appear red and irritated, with scales that cling to the base of the eyelashes. Blepharitis may be associated with repeated styes and chalazion .

Risk factors are poor hygiene, seborrheic dermatitis of the face or scalp and allergies.

Prevention:
Cleaning eyelids carefully will help restore the normal environment for the eyelid.

Symptoms:



Signs and Tests:
An examination of the eyelids is usually sufficient to diagnose blepharitis.

Treatment:
Depending on the cause, medications applied to the eyelid (topical), such as: antibiotics and/or corticosteroids (see corticosteroids - topical - low potency) will treat the infection and reduce the swelling .

Careful cleansing of the eyelids with a clean lint-free cloth soaked in warm water will help to remove the crusts. Often, a mild baby shampoo can also be used for cleansing.

If present, seborrheic dermatitis should be treated.

Lice may be eradicated by smothereing them with petroleum jelly applied to the base of the lashes.

Prognosis:
The probable outcome is good with treatment.

Complications:

  • prolonged infection
  • injury to the eye tissue ( corneal ulcer ) from irritation
  • inflammation of the lining of the eye ( conjunctivitis )
  • loss of eyelashes
  • scarring of the eyelids

Call for an appointment with your health care provider if symptoms worsen or do not improve after careful cleansing of the eyelids for 2 or 3 days.
