I was put on this drug for Migraines. I was previously taking Remeron for the migraines, which worked wonderfully, but had the unpleasant side effect of 35 lb weight gain and fatigue. Thankfully my Dr. had me try this Vivactil on a daily basis, which has helped me immensely without the weight gain problem.
Sunday, October 30, 2005. Optic Nerve Answers. The optic nerve is the bundle of axons that extend from the cell bodies of ganglion cells in the retina to synapse on the lateral geniculate body in the brain. The optic nerve as a structure begins at the optic disk. A smaller, disc-shaped depression, called the cup, lies slightly temporal to the center of the optic disc.
The optic nerve is a cable of nerve fibers that carry electrical impulses, containing visual information, from the eye to the brain.5) Finally, the fibers also have to be guided back appropriately to their original target to re-form functional connections. Each of these steps presents a great challenge to our efforts to repair an injured optic nerve. In the past, most attempts to promote optic nerve regeneration focused on only one of these steps.
