Choroidal Thickness in Eyes with Band Atrophy of the Optic Nerve from Chiasmal Compression.

The choroid does not thin after the inner retinal layer becomes damaged due to CCL and may even be thicker in some areas with corresponding severe retinal neural loss. While further studies are needed to interpret these findings, choroidal thinning is most likely not secondary to optic nerve disease-related inner retinal neural loss.
