To the Editor.
—The December 1989 issue of the Archives arrived in Israel in February 1990 and it was with the greatest interest that I read the pioneering work by Sergott et al1 on optic nerve decompression in nonarteritic ischemic optic neuropathy (NAION). I had a similar idea in October 1989 when I referred a patient with progressive NAION to undergo fenestration of the optic nerve sheath, and in this single case I can confirm the findings of Sergott et al in their larger series of patients. In fact, as they were in two of their cases, I too was surprised to observe an improvement in the visual outcome not only in the operated eye but also in the visual function of the unoperated eye affected by NAION in the past.
Report of a Case.
