Overview
Blepharitis is usually asymptomatic until the disease progresses. As it progresses, the patient begins to notice a foreign body sensation, eyelid crusting, matting of the lashes, tearing, and burning. Symptoms are typically worse in the mornings. Blepharitis can frequently be improved but are rarely eliminated. If left untreated, sever blepharitis may cause alterations in the eyelid margin, loss of eyelashes, scarring of the eyelids, conjunctivitis, corneal involvement (corneal neovascularization and corneal ulceration), and superficial keratopathy, and ultimately blindness.. Common complications of blepharitis include Hordeolum, chalazia, corneal ulcer, conjunctivitis, and loss of eyelashes,
Blepharitis is a chronic condition. It is associated with good prognosis. however, severe blepharitis is rarely associated with corneal neovascularization, and superficial keratopathy, and therefore these patients have a poor long term prognosis.
Natural History
Blepharitis is often caused by an overgrowth of the bacteria (Staphylococcus aureus), and meibomian gland dysfunction (MGD). It is usually asymptomatic until the disease progresses. As it progresses, the patient begins to notice a foreign body sensation, eyelid crusting, matting of the lashes, tearing, and burning. Symptoms are typically worse in the mornings. Blepharitis can frequently be improved but are rarely eliminated. If left untreated, sever blepharitis may cause alterations in the eyelid margin, loss of eyelashes, scarring of the eyelids, conjunctivitis, corneal involvement (corneal neovascularization and corneal ulceration), and superficial keratopathy, and ultimately blindness.
Complications
Complications to viral conjunctivitis include:
- Hordeolum
- Chalazia (usually painless firm lump caused by inflammation of the oil glands of the eyelid, and can be painful and red if there is also an infection)
- Corneal ulcer
- Conjunctivitis
- Loss of eyelashes
- Scarring of the eyelids
Prognosis
Blepharitis is a chronic condition. Blepharitis is associated with good prognosis, with exacerbation and remission as the natural history. Patients should be informed that symptoms can frequently be improved but are rarely eliminated. Continued treatment will typically make the eyes less red and more comfortable.
Severe blepharitis is rarely associated with permanent alterations in the eyelid margin or vision loss from superficial keratopathy, corneal neovascularization, and ulceration, and therefore these patients have a poor long term prognosis.
