I would definitely go see your eye doc to be on the safe side!
I had read somewhere that Uveitis can be a serious symptom of UC, so I had myself checked out when I was first diagnosed with UC, I told her I had UC, and my doc gave me the all clear...but failed to mention that dry itchy eyes are often linked to UC....Its so depressing, you would have thought she would have known that, being an Opthamologist...and it cost me $100 for the frigging appointment.
I only discovered a couple of days ago, through this forum, that the reason my eyes are itchy and dry is due to UC!...bugger!
