4. BACTERIAL BLEPHARITIS
Also known as chronic anterior blepharitis or
staphylococcal blepharitis or ulcerative blepharitis
is a chronic infection of the anterior part of lid
margin.
ETIOLOGY
Causative organisms : staphylococci
streptococci
propionibacterium acnes
5. CLINICAL FEATURES
• chronic irritation
• Itching
• mild lacrimation
• gluing of cilia
• mild photophobia
SYMPTOMS
• yellow crusts at roof of cilia
• small ulcers
• red, thickened lid margin
• mild papillary conjunctivitis
SIGNS
6.
7. COMPLICATIONS AND SEQUELAE
• Lash abnormalities like madarosis, trichiasis,
poliosis
• Tylosis, i.e. thickening and scaring of lid margins
• Eversion of punctum leading to epiphora
• Eczema of skin and ectropion
• Marginal keratitis
• Tear film instability
• Secondary inflammatory and mechanical changes.
8. TREATMENT
1. Lid hygiene
Warm compresses for 5-10mins
Crust removal and lid margin cleaning
2. Antibiotic eye ointment
Applied at lid margin after removal of crust.
Eye drops 3-4 times a day
Oral antibiotics like erythromycin or doxycycline
3. Topical steroids : fluoromethalon
4. Ocular lubricant ie artificial tear drops.
9. SEBORRHOEIC OR SQUAMOUS BLEPHARITIS
Anterior blepharitis with some spill over posteriorly.
ETIOLOGY
Seborrhea of scalp
SYMPTOMS
Whitish material at lid margin
Mild discomfort
Irritation
Falling of eyelashes
10. SIGNS
• Accumulation of white dandruff like scales on lid
margin
• Lashes fall out easily
• Lid margin thickned, posterior border rounded
leading to epiphora.
• Signs of bacterial blepharitis in patients with mixed
seborrhoeic and bacterial blepharitis.
11.
12. TREATMENT
• Improvement of health and balanced diet
• Treatment of seborrhoea of scalp
• Removal of scales with lukewarm solution of 3%
soda bicarb or baby shampoo.
• Application of combined antibiotic and steroid eye
ointment at lid margin.
• Antibiotics
13. POSTERIOR BLEPHARITIS (MEIBOMITIS)
Meibomitis, ie. Inflammation of meibomian glands
occurs in chronic and acute forms.
Chronic meibomitis
Pathogenesis: Bacterial lipases
Symptoms : Chronic irritation
Burning
Itching
Grittiness
14. SIGNS
White frothy secretions on lid margin
Opening of gland becomes prominent.
Vertical yellowish streaks shinnig through conjunctiva
Hyperemia of posterior lid margin.
Acute meibomitis
Staphylococcal infection.
Painfull swelling around the gland.
15.
16. Treatment of meibomitis
1. Lid hygiene
Warm compresses
Expression of secretions by vertical massage of lid.
2. Topical antibiotics and eye drops used 3-4 times a day.
3. Systemic tetracyclines
Doxycycline 100mg bdfor 1 week then od for 6-12wks
4. Ocular lubricants
5. Topical steroids like fluromethalon.
17. PARASITIC BLEPHARITIS
ETIOLOGY
Infestation of lashes by lice.
Phthiriasis palpebrum: infestation by
phthirus pubis (crab louse)
Pediculosis : infestation by pediculus
corporis (head louse)
21. TREATMENT
• Mechanical removal of lices and nits with
forceps
• Application of antibiotic ointmentsand yellow
mercuric oxide 1% to the lid margins and
lashes.
• Delousing of the patient , family members,
clothing and bedding is important to prevent
recurrences.
26. Signs
• Stage of cellulitis :
Localised, firm, red, tender swelling
at lid margin with marked oedema.
• Stage of abscess :
Visible pus point on the lid margin
in relation to affected cilia.
27. TREATMENT
Hot compresses - 2-3 times a day
Evacuation of pus by pulling out the
infected cilia
Antibiotic eye drops – 3-4 times a
day & eye ointment – Bed time
Systemic anti inflammatory &
analgesis
Systemic antibiotics
29. ETIOLOGY:
• Prediposing Factors:
Similar to hordeolum externum.
• Causative Mechanism:
Occurs as:
Primary staphylococcal infection of
meibomian gland
Secondary infection in a chalazion.
30. CLINICALPICTURE
• Symptoms:
• Similar to hordeolum externum,
except pain is more intense, due to
swelling embedded in dense fibrous
tissue.
• Signs:
• Maximum tenderness & swelling away
from the lid margin.
• Pus usually points on the tarsal
conjunctiva.
31. TREATMENT
• Similar to externum
• When pus is formed – drained by vertical
incision from tarsal conjunctiva.
32. CHALAZION
Tarsal or meibomian cyst.
Chronic non - infective granulomatous
inflammation of meibomian gland.
Commonest of all lid lumps.
33. Etiology
• Predisposing Factors:
Similar to hordeolum externaum
• Pathogenesis:
Mild
infection
of
meibomia
n gland
Proliferation
of epithelium
& infiltration
of wall of
ducts –
blocked.
Retention of
secretions (
sebum) in
the gland-
enlargemen
t.
Pent-up
secretions
(fatty in
nature)-
irritant &
excite non-
infective
lipogranulo
matous infl
of blocked
m.gland
35. Signs:
• Nodule – Firm to hard & non tender on
palpation.
• Upper lid – More common (contain more
meibomian gland).
• Reddish purple area – Pal.Conjunctiva.
• Projection – Skin side.
• Marginal chalazion – Small reddish grey
nodule on lid margin.
36. Clinical course & complications
Complete spontaneous resolution occur.
Slow increase in size.
Fungating mass of granulation tissue
Secondary infection – formation of
hordeolum internum.
Calcification
Malignant change – meibomian gland
carcinoma. (elderly pepole).
37. Conservative treatment – Hot
fomentation, topical antibiotic eye drops
& oral anti inflammatory drugs.
Intralesional injection of long acting
steroid (triamcinolone).
Diathermy
Oral tetracycline – Prophylaxis (if
ass.acne rosacea).
