I thought that I was having ocular migraines, but now I think it may be something else, like low blood pressure to my head. Mine are too consistant to be migraines. EVERY time I stand up or walk for very long (10 mins or more) everything becomes so bright that I can barely see, sometimes when I stand up. My eyes are also super sensitive to light. I NEVER had this happen until my symptoms started, before my diagnosis (AI), after a BAD headache. I actually thought that my Atenolol dose was too high, as all my symptoms were consistent with the overdose warnings on the label. That was the appointment the doc heard the murmur. After I stopped the meds, the vision problems continued. I do have migraines from time to time, usually with aura - this is different. Mine is both eyes, entire feild of vision. My eyes are hazel by the way ;0)
