dachryocystitis ( inflammation of the lachrymal
gland usually of infectious origin .)
The most common allergic cause is hay fever . •
Oral anti histamines and vasoconstrictors eye •
drops are used for treatment of allergic •
Conjunctivitis and sodium cromoglycate is used for •
the treatment of allergic rhinitis .

by Staphylococcus aureus .Streptococci •
,Pneumococci,and haemophilus Influenza, •
may also be responsible in some cases . •
Both bacterial and viral conjunctivitis may •
be associated with sore throat .
Management of infectious conjunctivitis is •
by the use of specific topically •
antimicrobial
Agents. •
Trachomonal conjunctivitis caused by •
chlamedia trachomatis and prasitic
conjunctivitis caused by the worm onchocerca
volvulus are more frequently occur and are
the cause of blindness in the poor countries
of the word.
They can be prevented by tetracyclin and •

•
Signs and symptoms of conjunctivitis : •
a- Burning or foreign body sensation or a •
feeling of grittiness .
b- photophobia and pain, when present , •
indicate a probable corneal involvement .
N.B.Pain that is worse on waking and •
improves during the day suggest an
infection .and if it is associated with more
profuse tear flow during the day so it is
infective micro-organisms.
In the case of keratoconjuntivitis sicca which •
is caused by inadequate tear flow the pain
gradually becomes worse as the day goes by.
c- Itching which is severe in case of allergic •
and atopic conjunctivitis .
d- mucoid discharge lead to incrustation and •
difficulty in in opening the eyes in the morning
e- Hyperaemia or redness , lachrymation •

iritis .
