title: [Optic disc drusen. Communication 2. Their role in the etiopathogenesis of optic neuropathy].
abstract: Forty-five patients (83 eyes) aged 17 to 80 years with optic disc drusen (ODD) were examined. Acute anterior ischemic optic neuropathy (AION) was detected in 6% of all the cases. Chronic optic neuropathy (ON) was revealed in 60%, which was predominantly slowly, progressive, asymptomatic and manifested as changes in the paracentral and peripheral fields of vision. Ultrasound study showed small-sized ODD in patients without clinical signs of optic nerve pathology and large-sized ODD in patients with manifestations of chronic ON. ODD affected central retinal artery blood flow (CRABF): in 96.8% of the patients with chronic ON and in 45.5% of those without visual impairments. There was a relationship of the values of the field of vision and CRABF to the extent of ODD.
