'Heteronymous' hemianopia refers to opposite halves for each eye as in bitemporal hemianopia. 'Homonymous' defects affect the same side for each eye, characteristic of retrochiasmal lesions.

A suspected bitemporal hemianopia needs urgent same day referral as the sooner the cause is identified the greater the chance of any visual recovery.
