Systemic Conditions in the Emergency Eye Clinic

Abstract

Purpose

A systemic disease may be diagnosed for the first time in patients who present to the eye department with ophthalmological manifestations. This study documents the pattern of systemic disorders which were encountered in an emergency eye clinic for the first time.

Subjects and method.

Over a period of six months details of all patients who had a previously unknown systemic condition diagnosed in the Emergency Eye Clinic were recorded. Patients were seen in this clinic upon referral from other practitioners. All patients, with the exception of those with minor ophthalmic problems, were screened for hypertension and glycosuria. The patients were subsequently referred to their general practitioner or the appropriate hospital specialist for further management.

Results

During this period 1025 new patients visited the emergency eye clinic. Previously undiagnosed systemic disease was present in 86 patients (8.4%). The commonest disorders were neurological 35 (41%), cardiovascular 17 (20%), glycosuria 13 (15%) and respiratory 5 (6%). Visual disturbance and pain were the most frequent ocular presentation. In 54 patients (62.8%) the ocular condition was a direct manifestation of the systemic condition and in 32 patients (37.2%) the systemic disease was a coincidental finding.

Conclusions

Awareness of ophthalmological manifestations of systemic disorders helps in the early diagnosis of these conditions and reduces the resulting morbidity and possibly mortality. This study illustrates the hidden role of the emergency eye clinic in identifying patients with an underlying systemic condition.
