Abstract
Degeneration of neuron and axons following injury to cells with which they synapse is termed trans-synaptic degeneration. This phenomenon may be seen in postsynaptic neurons (anterograde) or in presynaptic neurons (retrograde). Retrograde trans-synaptic degeneration (RTSD) of the retinal ganglion cells and retinal nerve fiber layer following injury to the occipital lobe has been well documented histologically in animal studies, but its occurrence in the human retina was, for many years, felt to be limited to cases of neonatal injury during a critical period of neuronal development. Over the last decade, imaging techniques such as MRI and optical coherence tomography have allowed us to visualize and quantify RTSD and analyze its time course and relationship to degree of vision loss and age of cortical injury. A deeper understanding of RTSD in the human visual system may allow us to interfere with its occurrence, potentially allowing for greater recovery following visual cortex injury.

Mitchell et al. devised a normalized asymmetry score to quantify RTSD in the GCL using OCT in 15 patients with adult-onset cortical injury, noting its onset by 1 year post-injury. They found that the time course of GCL atrophy extended as far out as 10 years. Of note is that RTSD was not observed in two patients with quadrantanopia from lesions that were over a decade old, demonstrating that RTSD of the GCL does not occur in every case.

Gabilondo et al. showed that loss of visual cortex volume on MRI and a decrease in NAA signal on MR spectroscopy correlated with RNFL thinning, even when accounting for the occurrence of optic neuritis (ON), suggesting that this relationship was due to RTSD. Anterior trans-synaptic degeneration was also demonstrated as patients with optic neuritis had lower volume of their visual cortex, but not of the precentral gyrus.
