Classification and external resources

Right superior quadrantanopia. The areas of the visual field lost in each eye are shown as black areas. This visual field defect is characteristic of damage to Meyer's loop on the left side of the brain.
ICD-10 H53.4
ICD-9 368.46

Quadrantanopia (or quadrant anopia, as two words) refers to an anopia affecting a quarter of the field of vision.

It can be associated with a lesion of an optic radiation.[1] If Meyer's loop is lesioned, the vision loss is superior; if the parietal path is lesioned, the vision loss is inferior.[2]
