Blepharitis

Definition


Disease: Blepharitis Blepharitis
Category: Eye diseases

Disease Definition:

The skins of the eyelids, especially the part where eyelashes grow, namely the lid margins, are affected by blepharitis. The malfunction of the tiny oil glands near the base of the eyelashes is the main reason of blepharitis.

Blepharitis could be difficult to treat because it is usually a chronic condition. This condition doesn't cause permanent vision damage, despite the fact that it is uncomfortable and unappealing.

Symptoms, Causes

Symptoms:

Some of the signs and symptoms of this condition may be:

  • Itchy eyelids
  • Bubbly tears
  • Loss of eyelashes
  • Sensitivity to light
  • Red or watery eyes
  • Red, swollen eyelids
  • Crusted eyelashes upon awakening
  • Flakes on the skin around the eye
  • A gritty, burning sensation in the eye
  • Eyelashes that grow abnormally (misdirected eyelashes).

 

The appearance of eyelids might be greasy and crusted with scales clinging to the lashes. At night, this debris may cause the eyelids to stick together. In some cases, the person may need to force their eyes open due to these secretions. A person may also notice a dried tear secretion in the morning, which feels like a grain of sand.

Causes:

Blepharitis is a chornic eye illness that can have an impact on the outer part of the eyelids (anterior blepharitis) where eyelashes attach or the inner part (posterior blepharitis) that is in direct contact with the eye.

Some of the conditions that may be associated with blepharitis are:

 

  • A bacterial infection
  • Malfunctioning oil glands in the eyelid
  • Rosacea, which is a skin condition marked  by facial redness
  • Seborrheic dermatitis, dandruff of the scalp and eyebrows.


A combination of other factors may cause blepharitis in some cases, such as allergies or an infestation of lice on the eyelashes.

Complications

Complications:

A loss or abnormal growth of eyelashes (misdirected eyelashes) or scarring the eyelids are major results of blepharitis. Other complications could be:

Sty:

This condition is a bacterial infection growing near the root of the eyelashes. The outcome is a painful mass on the edge or inside the eyelid, most visible on the surface of the eyelid.

Chalazion:

It occurs when there’s a blockage in one of the oil glands at the margin of the eyelid. Bacteria may infect the gland, resulting in red, swollen eyelids. Unlike sty, this condition more common on the inside of the eyelid.

Dry eyes or excess tearing:

Awful oily substances and other debris cast from the eyelid, such as flaking associated with dandruff, can accumulate in the tear film, which is the water, oil and mucus solution that form tears.
The abnormal tear film affects the lubrication of the eyelids. Excessive tearing is stimulated by this irritation. The infection could expand to affect non-oil producing glands in the eyes and cause dry eyes.

Chronic pink eye:

Blepharitis can lead to repeated bouts of pink eye, which is also called conjunctivitis.

Injury to the cornea:

A sore or an ulcer may be developed on a person's cornea due to the irritation caused by the inflamed eyelids or misdirected eyelashes. Deficient tearing could predispose a person to a corneal infection.

Treatments:

Treating blepharitis may be difficult. Keeping good personal hygiene can lessen signs and symptoms and later prevent complications.

If the infection does not get better, an antibiotic cream or ointment might be prescribed while in serious cases, eye-drops that contain antibiotics and steroids are used. Treating the underlying causes of blepharitis, in case there are any, such as rosacea or dandruff, could relieve this condition.

Blepharitis retreats, but rarely vanishes completely. The most important factor in bringing conditions under control is by taking good care of one’s own general hygiene.
