Purpose:
To provide epidemiological data about patients attending an ophthalmic emergencies center of a general hospital.
Methods:
A retrospective analysis of all patients attending the emergency department (ED) of Rio Hortega Hospital during a 9-month period was carried out. Pathology was identified by International Classification of Diseases ((ICD9-CM) codes.
Results:
A total of 2914 visits have been examined: 6% of patients were under 20 years of age, 35.4% between 21-50, 29% between 51-70, and 23.3% over 71 years. Thirteen per cent of visits were due to injuries, 50.7% of which occurred in patients 21 to 50 years old. Almost half of visits were due to inflammatory conditions of the cornea, conjunctiva and eyelids.
Conclusions:
ED plays a major role in the ophthalmology departments in a hospital. Certainly a considerable proportion of these patients had conditions which could have been dealt with in an ophthalmic outpatient clinic or by general practitioners. Ocular trauma is a common cause of visits to the ED.
