Mechanisms of temporary drug induced binocular diplopia?

[aced126]

I am interested in finding out about neurobiological mechanisms of temporary binocular diplopia being induced by drugs. It can be induced by ketamine, DXM and alcohol (at high doses), all of which are modulating NMDA signalling. Am I on the right lines? I can't find any sources on wikipedia in the "temporary diplopia" section.

Loperamide. My habit gives it to me all of the time. ;-P
