Demand incidence and episode rates of ophthalmic disease in a defined urban population.

Abstract

To estimate demand incidence and episode rates of ophthalmic disease in a defined urban population over one year. Study of patients presenting with eye problems to general practice and eye casualty department. General practice and ophthalmic services in west Nottingham. 36,018 people from the combined practice lists of 17 Nottingham general practitioners. Ophthalmic disorder, age and sex of patient, and where presented. 587 consultations were recorded for ophthalmic problems, 1771 with general practitioners and 816 with eye casualty. Most consultations to general practice were by females (1066 (60%)), whereas men aged 15-44 accounted for most work in eye casualty. These men commonly presented with trauma. Infective conjunctivitis, the commonest condition, had an episode rate of 13.5/1000 population/year. Demand incidence for cataracts was 1.9/1000 population/year. Demand incidence for chronic conditions increased with age. As the average age of the population increases demand for ophthalmic services will rise. Planning and provision of resources to meet this increased demand should be considered now.
