Just a short note to thank Cathryn for referring me to Leighton, you were spot on I have the early onset of glaucoma. Its treatable with daily drops. Its the second time that you have helped my family out in a big way. You will not remember, but the first time was back in 1989, we brought our son Stuart in to see you when he was 5 and we had been advised by a clinic that he should wear glasses with one lens blocked out to correct a turn. You disagreed with this and prescribed glasses that he wore for about two years which corrected the fault.
