Can Botox for Relief of Migraines (Forehead, Neck, Shoulders) Cause Optic Nerve Damage?

I have been receiving Botox injections every 3 months for relief of migraines for the past two years from a neurologist. The injections are to the forehead, down the back of the neck and a few on the top of the shoulders. In the past few weeks I've been experiencing dizziness and blurred vision. When I went to my optometrist, he suggested that I may be experiencing optic nerve damage and had scheduled me for a Field Test. Can Botox cause optic nerve damage? If so, is it longterm?

Nerve damage from Botox

The fact that your injections were done by a Neurologist makes it unlikely that he injected any muscles of eye movement.

Blurred vision, unfortunately, can happen after Botox injections, due mostly to eyelid droop.

Optic nerve damage from Botox injections  has not been reported, nor is it pharmacologically  possible,

I recommend that you discuss your problem with the Neurologist who treated you.

Most likely, the problem will resolve itself in a few weeks or months.

Optic nerve damage secondary to Botulinum Toxin (Dysport or Botox)

While Botulinum Toxin (Dysport or Botox) can cause ocular muscle imbalance that can result in dizziness or blurred vision, it is unlikely that it can cause optic nerve damage.
