Ophthalmoscopic signs of obstructed axoplasmic transport after ocular vascular occlusions.

When axoplasmic transport in ganglion-cell axons is interrupted by ischaemia organelles accumulate in distended axon terminals at the edges of the infarct. This report illustrates the localized opaque swelling of nerve fibres shich develops at or near the optic disc after occlusion of the central retinal or posterior ciliary arteries. No such swelling occurs in patients who have a combined occlusion of these vessels.
