Axons can be several orders of magnitude longer than neural somas, presenting
logistical difficulties in cargo trafficking and structural maintenance. Keeping
the axon compartment well supplied with energy also presents a considerable
challenge; even seemingly subtle modifications of metabolism can result in
functional deficits and degeneration. Axons require a great deal of energy, up to
70% of all energy used by a neuron, just to maintain the resting membrane
potential. Axonal energy, in the form of ATP, is generated primarily through
oxidative phosphorylation in the mitochondria. In addition, glial cells
contribute metabolic intermediates to axons at moments of high activity or
according to need. Recent evidence suggests energy disruption is an early
contributor to pathology in a wide variety of neurodegenerative disorders
characterized by axonopathy. However, the degree to which the energy disruption
is intrinsic to the axon vs. associated glia is not clear. This paper will review
the role of energy availability and utilization in axon degeneration in glaucoma,
a chronic axonopathy of the retinal projection.
