Takeaway
Retrochiasmal lesions are associated with ganglion cell atrophy affecting one half of the macula, which manifests earlier in the optic tract than in retrogeniculate lesions.
Why this matters
Retrochiasmal lesions (located in the visual pathway between the optic chiasm and visual cortex) can lead to atrophy.
Macular involvement in these lesions has not been fully characterized, and it is not known how quickly atrophy occurs after lesion development.
