Dr. Phelps of psycheducation.org says meds are guilty until proven innocent.

I had double vision on only 2.5 mg of abilify and had to stop it only days in. I also had 2 very nasty falls, probably from blood pressure bottoming out. I wound up in the ER and got a neuro exam and CT there so it was pretty well confirmed it was the med.

I would see the GP and get checked. But also drugs.com's profile of abilify says: More common:
Difficulty with speaking
drooling
loss of balance control
muscle trembling, jerking, or stiffness
restlessness
shuffling walk
stiffness of the limbs
twisting movements of the body
uncontrolled movements, especially of the face, neck, and back
Less common:
Blurred vision
dizziness
headache
inability to move the eyes
increased blinking or spasms of the eyelid
nervousness
pounding in the ears

so I'd find it hard to believe it couldn't cause other visual issues.

My pdoc seemed to think it was a reasonable side effect and that was before we knew that I had severe reactions to APs; it was my first one.
