ABSTRACT
To describe the association between optic disc traction and non-arthritic anterior ischemic optic neuropathy [NAION].eighty three eyes of 83 patients with NAION were evaluated by optical coherence tomography [OCT] for detecting vitreous adhesion to the optic never head with separation form adjacent retina [partial posterior vitreous detachment]. Those who were negative for such adhesion underwent ultrasonography to detect complete PVD. Fifty male and 33 female subjects with mean age of 51.9 +/- 10yr were studied. Partial PVD with optic never head adhesion was found in 54 patients [65.1%] using OCT. Ultrasonography found complete PVD in all eyes with optically empty spaces in OCT. Vitreous traction on optic never head from PVD may play a causative role in some cases of NAION. This traction may impair vascular supply and axoplasmic flow leading to signs and symptoms of NAION
