Bitemporal hemianopia
A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise bitemporal hemianopia — the full SA Note notes add investigations, management, complications and 10 practice questions.
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
