1. Blepharitis By Dr. Amr Mounir Assistant Professor of Ophthalmology Sohag University

2. Blepharitis is one of the most common ocular conditions characterized by inflammation, scaling, reddening, and crusting of the eyelid. Although blepharitis by itself is not sight-threatening, it can lead to permanent alterations of the eyelid margin. Different variations of blepharitis can be classified as seborrheic, staphylococcal, mixed, posterior or meibomitis, or parasitic.

3. Symptoms: A gritty or burning sensation in their eyes, excessive tearing, itching, red and swollen eyelids, dry eyes or crusting of the eyelids.

4. Complications  Hordeolum or stye  Chalazia  Corneal ulcer  Conjunctiviti

5.  seborrheic, staphylococcal, mixed, Parasitis Anterior: Posterior:  Meibomitis

6.  Anterior blepharitis occurs at the outside front edge of the eyelid where the eyelashes attach .  Anterior blepharitis  is commonly caused by bacteria (staphylococcal blepharitis) or dandruff of the scalp and eyebrows (seborrheic blepharitis) or ulcerative blepharitis. Anterior blephritis

7.  Staphylococcal blepharitis  patients frequently exhibit mildly sticking eyelids, thickened lid margins, and missing and misdirected eyelashes.

8.  Seborrheic blepharitis  patients have greasy flakes or scales around the base of eyelashes and a mild redness of the eyelids.

9.  Ulcerative blepharitis  patients have matted, hard crusts around the eyelashes. Removing the crusts leaves small sores that ooze and bleed. These patients may also experience eyelash loss, distortion of the front edges of the eyelids and chronic tearing.

10.  can occur when the glands of the eyelids irregularly produce oil (meibomian blepharitis). This creates a favorable environment for bacterial growth. Posterior blepharitis can also develop as a result of other skin conditions, such as rosacea and scalp dandruff. Posterior blepharitis

11.  Phthiriasis palpebrarum is the most common eyelid infestation caused by  Phthirus pubis  (pubic lice), sometimes referred to as crab lice. Parasitic blephritis

12.  Treatment depends on the type of blepharitis.  The key to treating most types of blepharitis is keeping the lids clean and free of crusts.  Applying warm compresses can loosen the crusts. Then gently scrub the eyelids with a mixture of water and baby shampoo or an over-the-counter lid cleansing product.  In cases involving bacterial infection, an antibiotic may be prescribed. Treatment

13.  Lubricants  Corticosteroid drops or ointment can be applied several times daily to the eyelids or ocular surface until the inflammation is reduced.
