Hi, My sister and I both have Fibro/CFIDS. Both of us have severe reactions when we've had optical exams that included dilatation. We both immediately get severe headaches, nausea, cold sweats, panicky feeling (almost a full-blown panic attack because so many malfunctions are occurring all at once that you feel like you're just going to collapse). My sister absolutely refuses to ever have her eyes dilated again (she's 57 and hasn't since she was 25!). I haven't had mine done in about 15 years, the problem is I'm now an insulin-dependent diabetic, so yearly, complete eye exams are really essential. My question (finally..lol). Does anyone else have this reaction? We were wondering if it was just a familial thing or maybe one more ailment to attribute to DD? Would love to have responses...yea or nay!
