视神经乳头血液供应的解剖类型在急性、亚急性及慢性缺血性疾病的发病机理中起关键性作用。一般认为视神经的血液供应类型几乎都是完全相同的,以致于对所有缺血性的损害解释都基于同一种标准的血管类型。在过去的10年中,前部缺血性视神经病变在临床上经常可见。由于其临床特征有明显的个体差异,这些差异导致了其发病机理上的混乱和争 Anatomical Types of Optic Nerve Blood Supply Play a Key Role in the Pathogenesis of Acute, Subacute, and Chronic Ischemic Diseases. It is generally accepted that almost all types of blood supply to the optic nerve are identical so that explanations for all ischemic damage are based on the same type of blood vessel. In the past 10 years, anterior ischemic optic neuropathy is clinically frequent. Due to the obvious individual differences in their clinical features, these differences lead to confusion and controversy over their pathogenesis
