[Non-arteritic anterior ischemic optic neuropathy--case reports]

Nonarteritic anterior ischaemic optic neuropathy usually caused by hypertension, diabetes and hypercholesterolaemia is quite a common disease. Within its symptoms two are the most important: deep and often not reversible visual aquity loss and visual field defects. The decrease of visual aquity may be the first sign of systemic illness, which is noticed by a patient. In many cases the correct diagnosis and anti-oedematous, anti-inflammatory and vascular treatment may improve their visual function and general condition.
