ANGULAR CONJUNCTIVITIS

2. DEFINITION:-
 A subacute bilateral conjunctival inflammation sometimes caused b
y the Moraxella bacillus, marked by redness of the lateral canthi an
d scanty, stringy discharge that
adheres to the lashes.
 Also known as Moraxella conjunctivitis.

4. ETIOLOGY:-
 A) Age-Usually adults are affected.there may be
associated nasal discharge.
 B) Climate:- More common in spring and summer.
 C) Causative Agent:- Infection is carried by fingers
and handkerchiefs.rarely there may be ascending
infection from the nose.
 Incubation period is 4 days.
 The infection is usually bilateral and highly
contagious.

5.  Clinical picture:-
a) Irritaation
b) Itching
c) Smarting sensation in eye.

6.  Clinicasl signs:-
a) Hyperaemia and excoriation of
the epithelium of the intermarginal strip of
conjunctiva of the lid margin both at the inner and
outer canthus.
b) Excoriation of the skin in the
surrounding area near the canthi.
c) congestion of the bulbar
conjunctiva at the inner and outer angle.
d)Scanty and mucopurulent
discharge.

7. COURSE:-
 No tendancy to spontaneous cure,but course is
prolonged.

8. PATHOLOGY :-
Typical eczematous changes occurs in the surrounding skin.
Accumulation of chronic inflammatory cells,mainly plasma cells in
the subepithelial tissue.
This ferment is inhibited by tears and so the lesions occur,only in
those places which are not bathed in ttears.
Bacilli secrete the proteolytic ferment which macerete the
epithelium.

9. DIAGNOSTIC CRITERIA:-
 a) Excoriation and hyperaemia of the conjunctiva
of the lid margin,at the inner and outer canthhhus.
 b) Eczematous condition of the skin in the
immediate neighbourhood.
 C) Scraping from the lesions shows the typical
diplobacilli.

10. COMPLICATION:-
 Marginal corneal infiltration or corneal ulcer.

11. TREATMENT:-
 Zinc sulphate 1 % with 2 % acid boric drops 3
