Emergency canthotomy and cantholysis - Factors affecting confidence among ophthalmic trainees in the United Kingdom.

Purpose: Retrobulbar hemorrhage from trauma is the most common cause of orbital compartment syndrome. Emergency canthotomy and cantholysis is a vision-saving procedure. We sought to identify confidence among ophthalmic trainees in this procedure as well as any relevant factors that have any impact.

Methods: An online, confidential anonymous questionnaire was distributed to ophthalmology training groups in the UK. Questions explored the participant's stage of training and grade and confidence in this area as well as their ophthalmic experience in terms of training courses attended and elective versions of the procedure performed.

Results: We received 45 completed responses from the survey. 20/23 (87%) of junior trainees had not performed an emergency canthotomy/cantholysis to date, whereas 19/22 (86%) of senior trainees had performed between 1 and 5 such procedures. 15/23 (65%) of junior trainees had not performed an elective canthotomy compared to only 3/22 (14%) of the senior trainees. We found that the main factors that were associated with increased confidence level were the higher numbers of emergency and elective cases performed, training courses, and previous oculoplastic surgery rotation (P = 0.0001).

Conclusion: From our survey, we found low confidence levels among junior trainees due to limited exposure. Confidence appeared to be linked to both elective and emergency surgical experience of the procedure as well as training course and having worked in an oculoplastic surgery firm. Changes to training portfolio requirements for junior trainees to incorporate early oculoplastic experience may help to achieve this on a national scale.
