I had optic neuritis and in work use my computer every day for detailed design work, however I actually really struggled more with email as I couldn’t enlarge the text on received emails. I phoned up my IT department but they were of no use. Since then been unfortunately diagnosed with ms so am now more aware of where to go for advice. So, assuming you have advised your work of your diagnosis if they have an occupational health department you could enquire there. There is also the access to work scheme - they may be able to help - they give advice on aids to help people stay in work and can help pay towards the costs depending on circumstances, I’ve not contacted them yet, but hearing from others they are meant to be excellent. Also, depending on your eyesight there are low vision clinics in hospitals that might be able to help. There again your IT dept might be better than mine so if they recommend something please come back and tell us!
