Quadrantanopia
Quadrantanopia means loss of vision in one quarter of the visual field and often points to a brain or visual pathway problem.
When to get help quickly: Urgent hospital review is important if the vision loss comes on suddenly, especially if it is accompanied by weakness, speech difficulty, severe headache, or confusion.
Common symptoms
A person may notice missing part of what they are seeing on one side, bumping into objects, difficulty reading, or trouble noticing people or movement in one section of vision.
When imaging helps
Imaging helps look for the cause in the brain or visual pathway, such as stroke, tumour, inflammation, or another structural problem.
What radiology does
MRI or CT of the brain may be used to look for stroke, tumor, demyelination, or other structural causes.
What usually happens next
Treatment depends on the underlying cause and may include urgent neurological care, rehabilitation, or further specialist management.
