No specific treatments were noted; however, treatments that strengthen or protect the nervous system might be helpful

Some external causes such as trauma or surgery to the eye, and some internal causes such as an unknown virus, an inflammatory condition, or a familial tendency have been suggested.

Alexander Adie died in 1859.
