I'm due to have my final interview next week for the role of Trainee Driver. Whilst looking over the medical standards on the RSSB site, I noticed a subsection of the vision standards stating; (k)no progressive eye disease, I was diagnosed two years ago with an eye abnormality which should not affect vision according to the eye specialist. I have no symptoms and on no specialist plan/medical plan. I've tried to gather as much information online regarding the 'disease' however, I'm worried that I'll fail based on my diagnosis - despite being asymptomatic. Other than the abnormality I have no vision related problems. Is this a black/white standard, or does the medical professional make the decision case by case? I'm tempted to cancel my final interview next week as I would hate to be offered the job and then be medically unfit after all the hard work this far.
