In this video I explain all about bitemporal hemianopia. This is a condition that you might find in patients with pituitary tumours and acromegaly when the tumour grows large enough to press on the optic chiasm. This space occupying lesion causes compression and interrupts the signals innervating the inner portion of the retina, which is responsible for sensing the visual signals from the outer portion of the visual fields.
Great explanation! This topic was mentioned on one of the practice MCAT tests I took recently
