I have conflicting answers in my Kaplan Anatomy book and a Q-bank question:
An aneurysm at the junction of the ACA and Anterior Com. Artery that compresses the optic chiasm whould result in what?
Kaplan and HY says bitemporal inferior quadrant anopsia, but a question in Kaplan's book and Q-bank says bitemporal superior quadrant anopsia.
My question is simply does the aneurysm compress the superior part of the chiasm resulting in inferior anopsia, or the inferior part of chiasm resulting in superior anopsia.
Please clarify.
Much appreciated. PS State any sources where you get your info.

I think it's bitemporal hemi-anopsia because the tract is not divided yet to upper and lower parts.

well dear friend...
the superior fibers travel superior and inferior fibers travel inferior....
optic tract is usually compressed in the case you are telling when there is an anerysm but it depends upon the size of the aneurysm...
usually ACA aneurysm causes optic chiasma compression...
anyway...
