I'm On A Low Dose (25mg) Of Lamotrigine For Seizures

I'm on a low dose (25mg) of Lamotrigine for seizures (I had one seizure in January; may or may not have mild epilepsy possibly as result of TBA in 1980's). I know that one of the potential side affects is blurry vision. I also have Macular Degeneration (which is largely being held at bay with acupuncture) -- I have noted a bit of blurry vision recently; I'm not sure I would know how to tell any blurring caused by the drug or caused by the AMD, but I would lean to assuming the Lamotrigine. My question is, if the blurriness was being caused by the Lamotrigine, if my neurolgist recommended I should go of (or changed) the drug, would the blurriness subside, or is that side effect forever? And if you don't know, do you have contact information for the company that makes Lamotrigine? Thanks so much --
