Bilateral non-arteritic anterior ischemic optic neuropathy (NA-AION): case report and review of the literature.

摘要

PURPOSE/METHOD: To present a 72-year-old woman affected by non-arteritic anterior ischemic optic neuropathy (NA-AION). To our knowledge, this clinical case, showing a bilateral form of NA-AION, is uncommon as only very few similar reports have been published in the scientific literature at this time. RESULTS/CONCLUSIONS: Visual acuity was reduced to 6/20 in both eyes, color vision was absent and computerized perimetry showed an absolute and general reduction of the retinal sensibility within 30 degrees around the fixation point. Pattern visual evoked potentials and pattern electroretinograms showed normal morphologies but delayed latencies and reduced amplitudes. An updated review of the literature has also been done.
