"Costs which on several occasions I have said I will pay for, wouldn't you?"
I was not impling any financial costs, either that you would finance or on the NHS.
The best evidence we have on Functional Vision Loss is that the less investigations that are performed, the gentler the follow up schedule and management is the better the outcome.
That is the cost I'm referring to.
And I'm sorry if I was unclear.
In addition, I am certian that the assessment at GOSH covered more than just the eyes.
For example the checkerboard pattern test you describe is called Visually Evoked Potentials and measures the electrical activity all the way back into visual areas of teh barin.
And pupil testing tests nerve systems into the midbrain and top of the spine.
I'm not aware of much evidence regarding the proactive treatment of CBT, as opposed to the passive watchful waiting, but I know some of the literature does suggest CBT and the like.
You mentioned a therapist before, what area of counselling do they specialise in?
