Retinal complications of gas myelography
J. Oberman, H. Cohn and M. G. Grand
Bilateral retinal and preretinal hemorrhages with an acute and permanent
partial loss of visual acuity developed in a 60-year-old man after an
oxygen myelogram. In order to increase the contrast of the myelogram, a
greater volume of oxygen was injected in the subarachnoid space than the
volume of CSF that was removed. It is believed that the hemorrhages and
visual loss were secondary to the sudden increase in CSF pressure caused by
the excess volume of oxygen injected.
