bitemporal hemianopia
Last reviewed 06/2022
Bilateral hemianopia is a loss of temporal field vision in both eyes. This may be caused by a lesion that affects the centre of the optic chiasm and damages fibres from the nasal halves of the retina as they decussate.
Possible causes of this condition include:
- pituitary tumour
- craniopharyngioma
- suprasellar meningioma
