New drug...
We started Vigabatrin (brand name is Sabril) yesterday (250mg 2x/day). Here is a brief summary of the drug:

"Sabril was developed by a research laboratory in France in 1977. Unlike many other seizure medicines, which are discovered by accident, it was purposely developed with a specific plan in mind—preventing the breakdown of GABA, a neurotransmitter that inhibits brain activity. Sabril was first marketed in Europe in the late 1980s and was approved in Australia in 1993 and in Canada in 1994...Unfortunately, as many as 25% of patients who take it for a long time suffer damage to the retina of the eye, which limits their field of vision. Because of this safety issue, the FDA has refused to approve Sabril, and its use has been restricted in some other countries."
