SYMPTOMS OF BLEPHARITIS
Blepharitis is a chronic malfunction and inflammation of the oil-producing glands in the eyelids.
There are 3 components to the tear film: oil, water and mucous. These 3 layers must be in balance to have normally functioning tears. Without proper combination of secretions, the tear film breaks down and becomes unstable. This causes itching, burning, grittiness and occasionally a red eye. This unstable tear film can also cause intermittent blurring of the vision. The eyes may feel dry or watery depending on the consistency of the tears. Sometimes the eyes may overflow with watery tears as the body tries to "flush" out this gritty sensation. Rarely, problems such as ulcers or scars in the cornea can be cause by blepharitis.
Blepharitis can begin as early as childhood, producing crusting of eyelids, styes, and, rarely, damage to the surface of the eyeball. For some children, it may continue throughout life, or in others may gradually resolve. Blepharitis can also start later in life and may be related to menopause or aging. There can also be associated dry eye, which will worsen symptoms.
Blepharitis is not an infection, but it reduces the eyes ability to fight bacteria and secondary infections, or severe bacterial overgrowth may occur in some cases.
STYES AND EYELID BUMPS
Oily build up at the lid margin can seal the opening of the ducts and cause little white lumps that look like whiteheads. Hot/warm compresses and gentle lid massage to "milk" the glands can restore flow through the pores. When glands become completely blocked they swell and may rupture and leak fatty debris into the lid. These leakages are toxic and create redness, swelling, pain and pus. This is not an infection but certainly appears to be one.
Styes will go away if left completely alone, but they can last over a year. Compresses are the first line of treatment. Incising and draining a stye may speed up the healing process.
