You should seek the advice of your veterinarian if your pet is ill as only he or she can correctly advise on the diagnosis and recommend the treatment that is most appropriate for your pet.

Acute disorders of the eye need to be differentiated so that the most appropriate treatment can be applied as soon as possible

This table may help differentiate between these three disorders:

 

Sign	Conjunctivitis	Iritis	Glaucoma
Discharge	Present - pus	Tears	Absent
Pain	Mild	Severe	Severe
Pupil	Normal	Contracted	Dilated
Intraocular pressure	Normal	Lower than normal	Increased
Anterior chamber	Normal	Cells, exudate, opacities	Shallow
Cornea	Normal	Precipitates	Opaque
Iris	Normal	Congested, discoloured, +/- posterior synechia	Congested and displaced
Conjunctiva	Superficial congestion	Deep congestion	Deep congestion
Sight	Normal	Slight impairment	Severe impairment
