Bitemporal hemianopia
A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Optic chiasm sits above the pituitary - crossing nasal retinal fibres (carrying temporal field information) are most vulnerable to compression
- Compression disrupts decussating fibres bilaterally → loss of temporal field in both eyes → bitemporal hemianopia; nasal fields preserved
