[Traumatic homonymous hemianopsia and ganglion cell complex changes: Report of 3 cases]. J Fr Ophtalmol. 2018 Nov 15;: Authors: Buisset A, Leruez S Abstract Homonymous lateral hemianopia follows an attack on the contralateral retrochiasmal visual pathways. In three patients with post-traumatic homonymous hemianopia, optical coherence tomographic (OCT) study of the ganglion cell layer thickness showed hemiretinal thinning contralateral to the visual field defect. This involvement could be explained by trans-synaptic degeneration of the pre-geniculate visual pathways, whose cell nuclei correspond to ganglion cells, which synapse with the damaged retrogeniculate visual pathways.
