Emergency department ophthalmoscopy: physician confidence and clinical practices

Fundoscopy is crucial in the emergency department to identify or rule out serious ocular and neurological conditions. Despite its clinical importance, fundoscopy is often omitted due to the technical challenges associated with traditional direct ophthalmoscopy, particularly for non-ophthalmologists. This study examines emergency physicians' practices, confidence levels, and training related to various modalities of fundoscopy including traditional direct ophthalmoscopes, binocular indirect ophthalmoscopes, panoptic ophthalmoscopes, slit lamp fundoscopy and fundus cameras; and explores the potential role of alternative modalities, such as fundus cameras, in Canadian emergency departments.

A cross-sectional survey was distributed to approximately 1000 emergency physician members of the Canadian Association of Emergency Physicians between March 4 and April 10, 2024. The survey, developed with ophthalmology and emergency medicine experts, included Likert scales and multiple-choice questions addressing confidence, practices, training, and experience with various fundoscopy modalities. Demographic data and responses were analyzed using descriptive statistics. Surveys were anonymous and available in English and French.

Seventy-four emergency physicians participated (mean experience 17.8 years), representing all Canadian provinces and territories. Most reported experience with traditional direct ophthalmoscopes (97.3%), slit lamp fundoscopy (82.2%) and panoptic ophthalmoscopes (58.9%). Only 1.4% had used binocular indirect ophthalmoscopes. No participant had experience with fundus cameras. Confidence in identifying fundus findings was low across all modalities, with only 13.7% reporting confidence using traditional ophthalmoscopes. Fundoscopy was performed frequently or always by 57.5% of the respondents, yet only 6.8% routinely used pupil dilation. Only 35.6% of the respondents felt their training in fundoscopy was adequate.

Emergency physicians in Canada report low confidence in fundoscopy despite its critical role in identifying vision- or life-threatening conditions. Traditional modalities are widely used but remain challenging for non-ophthalmologists. Fundus cameras, which offer ease of use and higher diagnostic accuracy, are underutilized.
