Visus writes: Questioning OCT policy

I recently saw this interesting letter to an ex/potential returning patient.

‘My receptionist has passed on the contents of the phone call from this morning. You requested an optical coherence tomography (OCT) which was suggested by your consultant rheumatologist. You were unhappy that we would be unable to undertake an OCT alone and that there would be a charge for the examination we would need to conduct. It is easier if I answer this in a letter. I am aware that you have been on Hydroxychloroquine (HCQ) therapy for some years, which predates your visit here in 2014 where it was recorded in your history.
