A straightforward task, to identify when a moving dot first appears in my visual field, repeated four times with different sizes and brightnesses of dot. First one eye and then the other. I reckon that I had sussed out the result before seeing the plots on screen. A slight reduction of the field in the upper left/right quadrants, indicating that there was slight pressure on the optic nerve already.
The lady I saw had nothing else to say except that they would have to tell DVLA who would be slow in deciding whether or not it was significant enough to stop me driving. Now THAT bothers me, not being able to drive would seriously inhibit my activities. Still, nothing I can do but sit and wait.
