Dry Eye / Chalazion / Blepharitis
A chalazion is a benign lump that forms within the oil-secreting glands (meibomian glands) of the upper or lower eyelid. The contents of a chalazion include blocked fatty secretions (lipids) that normally help spread the tear film evenly and reduce evaporation.
A chalazion will often resolve with warm compresses and gentle massage of the eyelid. However, some chalazia persist for more than several weeks, and may require a procedure to help them resolve.
Dry eye is a common ocular condition where the eye produces insufficient tears or poor quality tears, which lead to chronic soreness, dryness, irritation, ocular discomfort and blurred vision. A common symptom of dry eye is a watery eye, especially in windy conditions, as ocular irritation stimulates increased tear production. Although it is usually not a serious problem, it can have profound impacts on quality of life. In severe cases, it can lead to significant ocular surface complications. There are many interventions to treat dry eye which can improve ocular symptoms and quality of life.
Blepharitis is a common eyelid inflammation leading to chronic irritation and discomfort, redness of the eyelid margins and a foreign body sensation.
Blepharitis has two basic forms:
• Anterior blepharitis, affecting the base of the eyelashes.
• Posterior blepharitis, linked to dysfunction of oil-secreting meibomian glands within the eyelids. Often this leads to a poor quality tear film and dry eyes.
