Dry Eye Disease (DED)
Known by many different names, Dry Eye Syndrome is a relatively common condition affecting people of all ages and genders, although it tends to be more common with age and has a higher prevalence among women.
As the name suggests there is an insufficient supply of natural tears to keep the surface of the eye moist and healthy. Symptoms such as itchiness, dryness, and irritation, foreign body sensation or even difficulty wearing contact lenses are all commonly reported.
Dry Eye Syndrome can be caused by many factors including medication, smoking, menopause, diet and environmental conditions such as air-conditioning. Whatever the cause, your eye specialist or Doctor can properly diagnose Dry Eye Syndrome and recommend or prescribe the appropriate product(s).
Blepharitis is a condition where the rims of the eyelids become inflamed (red and swollen), which can result in symptoms such as:
- burning, soreness or stinging in the eyes
- crusty eyelashes
- itchy eyelids
Blepharitis can be caused by a bacterial infection, or it can be a complication of a skin condition such as:
How common is blepharitis?
- Seborrhoeic dermatitis, which causes an itchy rash on the skin and scalp (seborrhoeic dermatitis that affects the scalp is called dandruff)
- Rosacea, which causes the face to appear red and blotchy
- It is not possible to catch Blepharitis from someone else who has it.
Blepharitis is responsible for an estimated 1 in 20 eye problems reported to GPs. It is more common in people over 50, although it can develop at any age.
|Some forms of Blepharitis are caused by staphylococcus bacteria, up to half of these sufferers are effected by Dry Eye Disease|
(a condition where the eyes do not produce enough tears or dry out too quickly).Outlook
Blepharitis is a chronic (long-term) condition, which means that once it develops it can cause repeated episodes. There is no cure for Blepharitis, but establishing a daily eye-cleaning routine can help control the symptoms. This will need to be continued indefinitely. More severe cases of Blepharitis may require antibiotics.
Blepharitis is not usually regarded as a serious condition, the most common complication of Blepharitis is being unable to wear contact lenses while experiencing symptoms. Serious complications, such as sight loss, are rare, particularly if the recommended advice is followed.
Meibomian Gland Dysfunction (MGD)
Meibomian Gland Dysfunction (MGD) is thought to be the leading cause of dry eye disease (DED); a chronic disease, it is usually caused by obstruction of the secretory meibomian glands. The subsequent reduction of gland secretion results in a decreased amount of lipids in the tear film. This results in faster evaporation of the tear film and thus an evaporative dry eye. change above to MGD alone is responsible for about 60% of all cases of Dry Eye Disease, in combination with aqueous deficiency for a further 20% of dry eyes.¹(1) Klin Monbl Augenheilkd. 2012 May;229(5):506-13. doi: 10.1055/s-0031-1299533.
