Pathogenesis of Nonarteritic Anterior Ischemic Optic Neuropathy
Journal of Neuro-Ophthalmology, 2003Based on histopathology, electron microscopic corrosion cast studies, optic nerve blood flow studies, and clinical data, the pathogenesis of idiopathic nonarteritic ischemic optic neuropathy includes the following features: (1) structurally crowded optic discs are predisposed; (2) laminar and retrolaminar regions are the most common locations for ...

[Nonarteritic anterior ischemic optic neuropathy (nAION)].
Die Ophthalmologie, 2023Nonarteritic anterior ischemic optic neuropathy (nAION) is the second most common degenerative disease of the optic nerve. The pathogenesis remains elusive. A transient ischemia in the short posterior ciliary arteries not triggered by thromboembolic events is suspected.

TRANSVITREAL OPTIC NEUROTOMY FOR NONARTERITIC ANTERIOR ISCHEMIC OPTIC NEUROPATHY
RETINA, 2003To evaluate the role of transvitreal optic neurotomy in the treatment of nonarteritic anterior ischemic optic neuropathy, a scleral outlet compartment syndrome, in which neurovascular compression at the prelaminar and laminar regions of the optic nerve head may play a major role.Seven eyes of seven selected patients with severe vision loss (

Progressive and Recurrent Nonarteritic Anterior Ischemic Optic Neuropathy
American Journal of Ophthalmology, 1988We examined ten patients with nonarteritic anterior ischemic optic neuropathy in whom the visual deficit progressed over a number of weeks or who suffered a recurrence in the same eye. The visual deficits progressed over a month or more in five patients, four patients suffered a recurrence in the same eye after a long interval, and one patient had ...

Ipsilateral recurrence of nonarteritic anterior ischemic optic neuropathy
American Journal of Ophthalmology, 2001To report the prevalence of recurrence of nonarteritic anterior ischemic optic neuropathy (NA-AION) in the same eye and possible contributing risk factors.Cohort study.Institutional.The study includes 594 consecutive patients (829 eyes) with a diagnosis of NA-AION and follow-up of at least two months after the onset of NA-AION, examined in the Ocular ...

Nonarteritic Anterior Ischemic Optic Neuropathy and Intraocular Pressure
Archives of Ophthalmology, 1991Several reports have suggested that nonarteritic anterior ischemic optic neuropathy (AION) may be related to increased intraocular pressure. We reviewed the records of 45 patients aged 48 through 86 years with nonarteritic AION (10 patients had bilateral AION) for intraocular pressure measurements and the diagnosis of glaucoma or suspected glaucoma ...

Trombophilic screening for nonarteritic anterior ischemic optic neuropathy
Graefe's Archive for Clinical and Experimental Ophthalmology, 2005Nonarteritic anterior ischemic optic neuropathy (NAION) is an ischemic infarction of the optic nerve head, frequently leading to sudden, mostly irreversible loss of vision. In this study blood thrombophilic factors, as well as cardiovascular risk factors were investigated for their relevance to this pathology.
