Conjunctivitis means inflammation of the conjunctiva. Most important
conjunctivitis is caused by infection, milder conjunctivitis may be allergic
or from physical irritants such as foreign bodies, sunlight or wind. Rarely,
systemic disease or parasites may be the cause. Conjunctivitis may be
acute, subacute, or chronic.
Bacterial Conjunctivitis - may be caused by a wide range of organisms:
- Staphylococcus aureus
- Streptococcus pneumoniae
- Streptococcus pyogenes
- Haemophilus influenzae
- Koch-Weeks bacillus
- Morax-Axenfield bacillus
- Pseudomonas pyocynaea
- Neisseria gonorrhoea
Symptoms of Bacterial Conjunctivitis
- gritty, foreign body sensation
- photophobia
- lacrimation
- eyelids sealed together with discharge on wakening
- vision is clear and cornea is bright
Signs
- - diffuse redness of the conjunctiva of the eyeball and the eyelids
- - purulent discharge - but milder cases are free from discharge
- - possible corneal complications
Treatment
- Do not pad a discharging eye as by closing the conjunctival sac
conditions are favoured for bacterial proliferation.
- Sunglasses to diminish photophobia.
- Removal of discharges or secretions by the frequent instillation of
antibiotic eye drops.
- Eye ointment applied at bedtime has longer action then eyedrops
prevents sealing of lid margins by discharge.
- Awareness of the danger of spreading the infection to the other eye
or other people.
- Maintain a good personal hygiene.
Chronic conjunctivitis may follow an acute conjunctivitis that has been
inadequately or ineffectively treated, but failure to respond may be due to
some other lesion - viral corneal ulcer, foreign body, infected tear sac.
