Although specific diagnosis may require specialist ophthalmic expertise, using simple guidelines non-ophthalmologists as well as ophthalmologists can identify patients requiring emergency or urgent evaluation. Intensity and duration of pain, rapidity of onset and severity of visual loss (primarily assessed by visual acuity, which should be measured for each eye in all patients presenting with ophthalmic emergencies), gross appearance of the globe, and abnormalities on ophthalmoscopy are particularly important parameters.
