As you've not provided options, i would like to go with phenytoin.
Dose dependent side effects, visual s/e are first.

Heroin.

Anaesthetic with which barbiturate and diazepam are chemically incompatible?

Barbiturates and diazepam are chemically incompatible with ketamine. They should never be administered from the same syringe or via the same infusion set.

vigabatrin a GABA transaminase inhibitor associated with retinopathy characterized by an irreversible, bilateral, concentric peripheral visual field defect (pVFD).

yeah, vigabatrin is the answer... i should hav given the options.
