Abstract

Objectives Examination of the ocular fundus is imperative in many acute medical and neurologic conditions, but direct ophthalmoscopy by non-ophthalmologists is underutilized, poorly performed, and difficult without pharmacologic pupillary dilation. The objective was to examine the feasibility of non-mydriatic fundus photography as a clinical alternative to direct ophthalmoscopy by emergency physicians (EPs). Methods Adult patients presenting to the emergency department (ED) with headache, acute focal neurologic deficit, diastolic blood pressure ≥ 120 mmHg, or acute visual change had ocular fundus photographs taken by nurse practitioners using a non-mydriatic fundus camera. Photographs were reviewed by a neuro-ophthalmologist within 24 hours for findings relevant to acute ED patient care. Nurse practitioners and patients rated ease, comfort, and speed of non-mydriatic fundus photography on a 10-point Likert scale (10 best). Timing of visit and photography were recorded by automated electronic systems. Results Three hundred fifty patients were enrolled. There were 1,734 photographs taken during 230 nurse practitioner shifts. Eighty-three percent of the 350 patients had at least one eye with a high quality photograph, while only 3% of patients had no photographs of diagnostic value. Mean ratings were ≥ 8.7 (standard deviation [SD] ≤ 1.9) for all measures. The median photography session lasted 1.9 minutes (interquartile range [IQR] 1.3 to 2.9 minutes), typically accounting for less that 0.5% of the patient’s total ED visit. Conclusions Non-mydriatic fundus photography taken by nurse practitioners is a feasible alternative to direct ophthalmoscopy in the ED. It is performed well by non-physician staff, is well-received by staff and patients, and requires a trivial amount of time to perform.
