Quadrantanopia means loss of vision in one quarter of the visual field and often points to a brain or visual pathway problem.
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.
Imaging helps look for the cause in the brain or visual pathway, such as stroke, tumour, inflammation, or another structural problem.
MRI or CT of the brain may be used to look for stroke, tumor, demyelination, or other structural causes.
Treatment depends on the underlying cause and may include urgent neurological care, rehabilitation, or further specialist management.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
