I am beginning to realise that treatment varies so much throughout the country and no doubt the world. I am so lucky to be treated at Kingston Royal Eye Unit. I was a bit dubious as they did nothing for my thyroid eye disease 20 years ago until a specialist picked up on it and sent me to Moorefields. However for AMD they are amazing and unless you are in early stages of 4 week injections so don't always need a scan, you will get a scan which will be checked that day by a doctor who recommends the injection and when follow up should be. My brother in Scotland however seems to go for a scan then is often sent home (a 40 + mile round trip drive and otherwise 3 buses if he or his son did not drive) then has to to await the opinion of a doctor, await a letter with an appointment and has to return for the injection!! I think the streamlined one stop shop system far better and probably shaves off some NHS expense and time and admin costs.
Perhaps those not so lucky could join a patient group for whichever hospital (they are doubtless not alone) and point out how things could be improved for the benefit of all concerned. We Brits are good at grumbling individually but it doesn't necessarily get results unless directed at the right people.
