Monocular vision loss and scotomas
A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise monocular vision loss and scotomas — the full SA Note notes add investigations, management, complications and 10 practice questions.
Key high-yield points
- Lesion anterior to chiasm (optic nerve/retina) → monocular visual loss only
- Lesion at or behind chiasm → binocular homonymous field defects (same side of visual field in both eyes)
- Defect is always contralateral to the lesion
Left parietal lobe lesion → disrupts superior fibres of right optic radiation → right homonymous inferior quadrantanopia. Left temporal lobe lesion → Meyer's loop → right homonymous superior quadrantanopia.
