ABSTRACT
This chapter presents a discussion on the causes, diagnosis, and investigation of symptoms related to eye. It provides a general practitioner overview, differential diagnosis, possible investigations, and top tips for dealing with symptoms related to eye in patients. The symptoms discussed are Acutely red and painful eye; double vision; eyelid problems, flashes, floaters and transient visual disturbance; gradual loss of vision; itchy or irritating eyes or eyelids, and sudden loss of vision. The differential diagnosis includes common, occasional, and rare causes of the symptoms. Sudden loss of vision is a genuine general practitioner emergency. Most causes require an urgent ophthalmological opinion as there is little that the general practitioner can do.
