- 2. Definition- Blepharitis is aninflammatory condition of the eyelid margin, is a common cause of ocular discomfort and irritation in all age and ethnic groups.
- 3. Types- (Anatomical location) Anterior blepharitis- 1. Bacterial 2. Seborrehic 3. Parasitic Posterior blepharitis. Mixed

- 5. Bacterial blepharitis Reasonfor chronic anterior blepharitis Etiology- Coagulase positive staph Streptococci Propionibacterium acne moraxella
- 6. Clinical features signs symptoms Yellowcilia are seen at the root of the cilia which glue them together Chronic pain Small ulcers, bleeds on removal of crusts Itching Red thickened lid margins with dialted blood vessels lacrimation Mild papillary conjunctivitis and conjunctival hyperemia are common associations Glue cilia symptoms worse in the morning Remissions and exacerabations in the symptoms are quite common
- 7. Seborrheic blepharitis Itis the primary anterior blepharitis with some posterior spil over. Etiology- Associated with seborrhoea of scalp (dandruff). Gland of zeis- secrete abnormal excessive neutral lipids which are are spilt by corynebacterium acne into irritating free fatty acids.
- 8. symptoms signs Deposition ofwhitish material at the lid margin Dandruff like scales are seen on the lid margin, OILY GREASY CRUST, Irritation, Upon removing these scales lying surface found to be hyperemic(no ulcers) falling of eye lashes falling of eye lashes
- 9. Parasitic blepharitis Etiology Phthiriasispalpebram (mite/ectoparasite)
- 10. symptoms Signs Chronic irritationLid margins are red and inflammed itching Lice anchoring lashes can be seen on slit lamp examination burning Mild lacrimation
- 11. Posterior blepharitis/Meibomitis Acutemeibomitis- CA is staph Chronic meibomitis is a meibomian gland dysfunction, seen more commonly in middle aged persons with acne roasacea and seborrhoic dermatitis.
- 12. Symptoms signs Frothy (foamlike) secretion on eye lid margin On eversion of the eyelids, vertical yellowish streaks shinning through the are seen. Openings of meibomian glands become prominent with thick secretions
- 13. Conditions associated withchronic blepharitis Lash abnormality- triachiasis, madarosis, poliosis Epiphora- Eczema of skin and ectropion Recurrent styes/chalazion Tear film instability and dry eye. Acne vulgaris Atopic keratoconjunctivitis Bacterial keratitis
- 14. DIAGNOSIS In allforms of blepharitis, examination of the tear film may show instability and rapid evaporation. Tear break-up time (TBUT)- The time interval between a complete blink and the first appearance of a dry spot in the pre-corneal tear film after fluorescein instillation..<10 sec(ABN). Schirmer’s test. RECENT ADVANCES- Meibography-The silhouette of the meibomian gland structure is captured LIPIVIEW-This instrument measures the lipid layer thickness between blinks and gives a quantitative assessment.

Avoid rubbing of eyes Improvement of health and balanced diet Mechanical removal of parasite with the help of forceps. Expression of glands by repeated Vertical lid massage AB ointment/DROPS- tid/Qid Oral antibiotics- erythromycin Scalp dandruff should be treated adequately Delousing of patient and other family members, clothing and bedding Antibiotic eye drops- tid/qid Oral NSAIDS- to reduce inflammation. Removal of scales from lid margins with the help of baby shampoo. Antibiotic ointment over eye lids. Systemic tetracyclines(DOXYCYCL INES)- 6-12 weeks mainstay.
