doctor my eyes

Over the past few months I've been stuck in the NHS system trying to get my eyesight sorted out. Almost a year ago I noticed that my right eye wasn't picking up colours the same way my left was, everything seemed a little less vibrant, slightly darker and not as "all there" as the vision in my left.
.
After a routine optician's appointment I was referred to a specialist at the not-so-local hospital (the one who asked me to Google my symptoms). Thanks to the ineptitude of the person who wrote the appointment letter I had to revisit the hospital another time because they needed to put drops in my eyes that would seriously compromise my vision and prevent me from being able to drive safely. So, my second appointment with a different specialist resulted in me being told I might have a cataract and then being referred to Addenbrookes in Cambridge for a brain scan. "You can drive there as they don't need to put drops in your eyes" I was told.
.
The letter came from Addenbrookes confirming my appointment: "Please do not drive here as we will be putting drops in your eyes in order to inspect them better," it said. So I had to cajole my father-in-law into taking a day off work so that he could drive me there (in the worst rain I've seen). I could have taken the bus or the train, but from my previous experience with my vision after the eye drops went in I would probably have left the hospital and taken a bus to Aberdeen.
.
At Addenbrookes I sat with electrodes stuck on my head in a darkened room and spent 45 minutes watching a television that was showing a checkerboard where the black and white squares kept swapping colour. Then I went home.
.
Yesterday I had a follow-up at my not-so-local hospital and was told that I didn't have a cataract after all and that the nerves in my right eye were reacting slower and less efficiently than in my left, giving me the dodgy vision.
"There's nothing we can do about it; no operation, no medicine, no corrective lenses, nothing. It's a one-in-a-million thing," the consultant said (in other words "I haven't got a clue"). She put it down to a past inflammation in my eye that damaged the nerve.
.
I'm relieved I don't need a cataract op, after reading the helpful NHS booklet about having your lens sucked out of a slit in your eyeball it suddenly seemed less appealing. On the other hand I'm a bit disappointed that I'm stuck with gammy eyesight and the not knowing if it will deteriorate further.
.
SO that's my eye story. Learn from me, people - keep an eye on your eyes and if they go gammy, go to your doctor and get messed about by the NHS and end up with no resolution to your problem.
