vision problems were the first thing that tipped me off that I was one of the unlucky who are deemed allergic to the Plaquinil (sp?). As long as you are aware of what's happening, (and trust me, it's hard NOT to notice when your left peripheral vision goes) you should be fine. Another one I discovered was hard to ignore was loud ringing in the ears. At least my bad side effects were Really obvious. Best of luck to you. The eye exam should keep you informed.
