He did various test, he looked at my eyes under coloured lights and pressed various objects against their surfaces (not too hard and under a very local anaesthetic so it didn't hurt, just felt odd). He made his notes, consulted the chart from the last visual acuity field test I did and decided: yes this duck has wings. The pressure is markedly raised in my right eye and slightly too in the left and the field testing shows the classic arc of vision lose for the right eye. I have glaucoma.
I'm now on beta blocker drops which means that my snooker playing should improve but my hopes of being an Olympian have been dashed. I'm ok, although I will admit, I did have a little weep the next day I think that was more because I'm going to be on medication for the rest of my life and that seems so final. But really, the glass is more full than empty, it was spotted before any serious damage was done and with continuing treatment there's very good chance that I will never have noticeable sight loss.
