Hay fever or allergens e.g. eye cosmetics, eye drop ingredients
Symptoms include red eye, watery discharge, itchy, usually both eyes affected, possible other systemic sympoms
What is the treatment of allergic conjunctivitis?
Mast cell stabiliser eye drops e.g. sodium cromoglicate- Opticrom allergy
Antihistamine/decongestant drops e.g. antazoline/ xylometazoline- Otrivine antistin
POM treatments- mast cell stabilisers, antihistamines, short term topical steroids
What are the causes and symptoms of infective conjunctivitis?
Bacterial or viral infection
Symptoms include red eye, discharge (viral- watery, bacterial- sticky, purulent), usually starts in one eye then spreads to the other, slightly painful gritty sensation, vision unaffected, viral may be associated with other upper RTI symptoms
What is the treatment for bacterial conjunctivitis?
Antibacterial eye drops/ointments e.g. propamidine- Golden eye, Brolene

Usually self limiting but antibacterial drops will prevent secondary infection
What is a sub-conjunctival haemorrhage?
Burst blood vessel (looks worse than it is)
What are the symptoms and treatment of a sub-conjunctival haemorrhage?
Red eye, no pain, spontaneous event
No treatment required as will heal spontaneously
What are the symptoms and causes of inflamed/tired eye?
Regular rubbing of eyes
Rims of eyes red/bloodshot
Irritation
Causes: overexposure to smoke, driving, working at VDU
What is the treatment for inflamed/tired eye?

Advise to avoid causative factors
Artificial tears eye drops e.g. hypromellose, polyvinyl alcohol, sodium hyaluronate
Artificial tears eye gels e.g. Carbomer 980
Hydrophobic ocular lubricants e.g. lacrilube
Dry eyes spray
Why should a blunt injury to the eye always be referred?
May cause increase in pressure, detachment of retina or corneal scarring
Other eye conditions that need referring
Glaucoma
Iritis (pain in eye, red, pupil small)
Corneal ulcer (main symptom is pain)
What is a stye?
Inflammation of the margin of one eyelid, caused by infection of the hair follicle gland at the base of an eyelid
