:-( Not good. I had a big problem with occy health in my first year of med school (I have a moderate visual impairment) - it was all clearly documented on my pre-med-school screening questionnaire but they seemed to have totally overlooked it. I had a sudden massive problem in the middle of first year exams, had to be seen daily at the eye hosp for a while, blah de blah, so went to go and see the relevant people re. mitigation and the time I was needing off, and they feigned complete ignorance and had a bit of a hissyfit over the whole thing. Not fun when you're already dealing with a major and potentially life-changing exacerbation of something, and suddenly you've the med school trying all sorts to see if they can chuck you out on health grounds. (Although they did admit that they thought they'd seen every mitigation reason possible, until I submitted "I couldn't actually see the exam paper...") Thankfully, whilst my hospital consultant wasn't particularly supportive of me, he was at least factual. I also spoke to the GP tutor I'd been doing a day per fortnight with during first year, and she wrote a supportive letter to the med school explaining that in her opinion I'd had no problems with any clinical tasks from a visual perspective, including phlebotomy etc. Thankfully in the end all was ok, but it was a scary time. It's one of the big reasons that I encourage people to declare everything on their pre-med school questionnaire - I would have been in VERY hot water had I not written down; they got the form out and had to acknowledge it was their fault for overlooking it.
Nowadays, I still don't have enough vision to drive. There are a few things in hospital that I struggle with on occasions, but I've found ways round them. I manage to cannulate neonates without problem. if I'm leading a cardiac arrest, I make sure that I'm closer to the monitor to read the rhythm (I can't see it properly from the other end of the bed space but have no problem if I'm slightly closer). I make sure I have good lighting if I'm doing a clinical procedure, even if it's the middle of the night and the nurses get cross about all the lights going on. When the consultant used to do the whole "stand at the end of the bed and tell me what the eye signs are' I used to ask to come closer. The only thing I can't do is ophthalmoscopy. Thankfully now I'm a doctor, occy health seem to have been slightly more relaxed, and I've also managed to build up a good bank of evidence that I can carry out everything I need to for my job.
Fairy, don't give up - keep fighting them. It can be very demoralising at times, especially if your consultant's contacting them. Do you have a supportive GP? Sometimes they can be a lifesaver in these sorts of situations, perhaps an extra voice to reiterate that your consultant doesn't know enough to comment about a particular situation.
