Neural network differentiation of optic neuritis and anterior ischaemic optic neuropathy.
AIMS The efficacy of an artificial intelligence technique, neural network analysis, was examined in differentiating two optic neuropathies with overlapping clinical profiles-idiopathic optic neuritis (ON) and non-arteritic anterior ischaemic optic neuropathy (AION). METHODS A neural network was trained with data from 116 patients with 'gold standard' diagnoses of ON or AION. It was then teste...
متن کاملAnterior ischaemic optic neuropathy
In anterior ischaemic optic neuropathy (AION) there is a comparatively sudden loss of vision in the entire eye, or in one sector of the field of vision of the eye, initially associated with oedema of the optic disc, which results in optic atrophy within a month or two, leaving a permanent visual defect. A large number of such cases have been reported in the literature, but, although this clinic...
متن کاملOverlap of optic neuritis and anterior ischemic optic neuropathy.
Dr Horton’s letter, “Mistaken treatment of anterior ischemic optic neuropathy with interferon -1a” is an important reminder of the sometimes difficult distinction between optic neuritis (ON) and anterior ischemic optic neuropathy (AION). Although he touches on several distinguishing characteristics, the distinction is clinically important and merits further expansion. Both ON and AION represent...
متن کاملBilateral anterior ischaemic optic neuropathy due to optic disc drusen.
PURPOSE To report a case of bilateral anterior ischaemic optic neuropathy due to buried optic disc drusen. METHODS Case report. RESULTS A 64-year-old man presented with swollen optic discs and features suggestive of anterior ischaemic optic neuropathy (AION) in the left and right eye on two separate occasions ten months apart. Detailed ocular examination at presentation and systemic investi...
متن کاملTraumatic ischaemic optic neuropathy.
Persistent profound visual loss following contusion of the globe or ocular adnexae has been well documented, the visual loss being attributed to haemorrhage into, or contusion of, the optic nerve, or to interference with the blood supply of the eye. The patient described below presented after a contusion of the eye and orbit, with the clinical picture of ischaemic optic neuropathy presumably re...
