i haven't been diagnosed with diabetes, though i have been tested on a number of occasions for it...mine however, is kinda like a ribbon of colours that disrupt my vision, normally accompanied my migraines...in fact, all the time, not just normally. migraines, pain behind the eyes, and this colour ribbon blocking me from seeing anything..around the area where the ribbon appears, is normally blurred, so even if i wanted to "look around it" so to speak, i wouldn't be able to see anything anyway...any ideas what this could be? i've been to the opticians, but the best the could come up with was photophobia...but i'm not sure, it is quite hard to explain what it's like.
