CONJUCTIVA Flashcards
Conjuctivitis Definition classification basis s types Clinical Features
Inflammation of the conjuctivita
Classification based on
Aetiology = microbial and non microbial
Microbial = Bacterial , viral , Chlamydial , fungal
Non Microbial = Allergic , auto immune , chemical and toxic
Basis of Exudate watery , mucoid , mucopurulent , purulunt
Basis of conjuctival reaction
follicular and allergic
Watery discharge occurs in ?
Viral , acute inflammation
Mucoid discharge occurs in
chronic inflammation and keratoconjictvits sica
Mucopurulent discharge occurs in
Purulent occura in ?
bacterial inf (chlamydial infection ) Gonococal purulent discharge
Viral infectionsn
chlaymadial infection
topical medication lead to what kinda conjuxtival reaction
Follicular conjuctivitis
Allergic disorders Auto immune disorders chronic irritation chronic blepharitis topical medication
what kind a conjunctival rwaction
Papillary conjuctivitis
Clinical Features Of conjuctivitis
Symptoms
itching
lacrimation , stinging, burning
Signs Exudate Conjuctival response Papillary and chemosis = allergic conjuctivitis Follicular and subconjunctival = viral conjunctivitis Hyperamia (redness of conjuctiva ) lymphadenopathy corneal involment in keratoconjictvits
Bacterial Conjuctivitis is div in to
Muco purulent
purulent
membranous
Pink Eye / mucopurulent
def
cause
pink eye ?
Staoh aureus
strep pneumonia
hem inf
In severe form whole conjuctiva is hyperemic called PINK eye
mucopurulent discharge
Gonococoal /purulent conjuctivitis
Def
hyperacute inf of conjuctiva
characteriized by purulent discharge and redness of the eye .
causes
Neisseria gonorrhea
Membranous conjuctivitis
causes
inf of conjuctiva characterized by membrane formation on conjuctiva
Corynebacterium diptheria
true and pseudo membrane
complication
corneal ulcer
conjuctiva
cilliary body
Mollosum Contagiosum conjunctivitis
viral infection of skin and less commonly of conjuctiva
causes Double stranded DNA virus Pox virus group
clinical features
Umblicated nodules on lid margins Eye lids
Follicular conjuctivitis = Conjunctiva
CHLAYMADIA CAUSES ?
Trachoma AC
Adult inclusion conjuctivitis DK
Neonatal Inclusion conjuctivitis DK
TRACHOMA
def ?
Causes ?
Chronic Bilateral Cicatricial Keratoconjictvitis
causes = Chlaymadia A-C serotype
Pathogenesis of Trachoma ?
Organism enters epithelial cells of (conjuctiva and cornea ) as INCLUSION BODIES
Epithelial involvement = Lymphocytes infiltration of the whole subepithelial fibrous layer ( adenoid layer) follicular formation
Follice rupture replaced by Scars
distortion of conjuctiva and eyelids = complication
