3. INTRODUCTION/DEFINITION
Blepharitis is a subacute or chronic inflammation of the lid margins., it
usually affects both eyes along the edges of the eyelids.
The eyelids can become irritated and itchy, and appears greasy and crusted
with scales that cling to the lashes.
It commonly occurs when tiny oil glands near the base of the eyelids become
clogged, causing the irritation and redness.
It can be uncomfortable and unsightly, but it usually doesn’t cause any
permanent damage on your eye sight.

4. Blepharitis is an extremely common disease which can be divided into
the following clinical types
• Seborrhoeic/squameous blepharitis
• Ulcerative blepharitis
• Posterior blepharitis (Meibomitis)
• Parasitic blepharitis
TYPES OF BLEPHARITIS

5. SEBORRHOEIC/SQUAMEOUS BLEPHARITIS
It is usually associated with seborrhoea of scalp(dandruff). Some
metabolic factors play a part in its etiology. In it, glands of Zeis secrete
abnormal excessive neutral lipids which are split by corynebacterium
acne into irritating free fatty acids.
SYMPTOMS
• Patients usually complain of deposition of whitish material at the lid
margins associated with discomfort.
• Irritations
• Occasionally watery eye and a history of falling of eyelashes

6. CONT.
SIGNS
• Accumulation of white dandruff-like scales are seen on the lid margin., On
removing these scales underlying surface is found to be hyperaemic (no
ulcers).
• The lashes fall out easily but are usually replaced quickly without
distortion.
• In long standing cases, lid margin is thickened and the sharp posterior
border tends to be rounded leading to epiphoria
TREATMENT
• Improvement of health and balanced diets
• Associated seborrhoea of the scalp should be adequately treated
• Frequent application of combined antibiotics and steroid eye ointment at
the lid margin
