- English & Arabic
- Education & training
Your first practice session
- Start with a normal scan and identify the visible structures.
- Choose a case and describe the observed changes.
- Compare your interpretation with the learning material.
Common mistakes to avoid
- Naming a diagnosis without describing the scan.
- Treating a teaching scan as a substitute for complete clinical assessment.

Understand the principles
Visual pathway lesions and the visual field defects they cause
The pattern of a visual field defect shows where the visual pathway is damaged. A lesion in front of the optic chiasm affects one eye; a lesion of the chiasm typically causes a bitemporal hemianopia; and any lesion behind the chiasm causes a homonymous defect on the opposite side in both eyes. The further back the lesion, the more congruous — alike in the two eyes — the defect becomes, so an occipital lesion gives a congruous homonymous hemianopia, often with macular sparing.
