               BLEPHARITIS - RAIN HEALTH CARE

WHAT IS BLEPHARITIS?

Blepharitis is the subacute or chronic inflammation of the eyelids.It can affect the eyelash roots and the area immediately behind this.

PATHOGENESIS----

The normal eyelid contains glands that secrete a thin and oily fluid, which serves to coat the tears, allowing them to spread evenly across the eye and preventing them from evaporating too quickly. 

• In patients with Blepharitis, the secretions from these glands often become thickened and plug the openings of the glands. 
• Once secretions stagnate, the fatty acids in the oils begin to break down into by-products that areirritating to the eyelids and the surface of the eye.
• Eyelids then become red and inflamed.  Many patients experience burning, itching, dry eye and foreign body sensation related to this irritation. 
• The irritated eye then secretes more mucous and protein which often build up on the eyelid and lashes in the form of crusting which is present especially upon awakening the morning.
• This crusty material provides a good surface on which bacteria may grow.  The bacteria then secrete irritating substances that further irritate the eye and can damage the glands of the eyelids.
• If allowed to continue, the condition may become progressively worse, leading to chronic eyelid inflammation, irritation, and decreased vision.
