Barry Duncan, deputy chief executive of ABDO, has resigned with immediate effect.
Barry has been on the staff of ABDO since 2011 and is a former president of the Association.
Commenting on Barry’s resignation, ABDO general secretary, Sir Anthony Garrett, said: “Barry has played a major part in the development of the Association in recent years – particularly the reorganisation of our structure into regions with regional leads – and developing a network of local leads.
“In addition, his pioneering work on the development of a minor eye conditions service programme for contact lens opticians is a major achievement, which will grow in the years to come.
“I wish Barry every success in his future career.”
