Cambridge Ophthalmological Symposium 2018: introduction and reflections on the day.

I was privileged to be one of the co-chairs, along with Professor Tim Sullivan (Brisbane, Australia), for the Cambridge Ophthalmological Society (COS) annual international symposium, which, this year, was dedicated to thyroid eye disease (TED). Together with the organisers, Miss Rachna Murthy and Professor Keith Martin from COS, we compiled an impressive programme covering all aspects of the condition from events happening in a single orbital cell to improved surgical approaches.
