视神经乳头水肿视神经乳头水肿(简称乳头水肿)是指视乳头的一种非炎症性变化而被动地产生水肿而言,临床上也叫淤血乳头,是一种常见的临床症征,80%以上是由于颅内疾病引起的颅内压增高而引起,具有极为重要的诊断意义。一、乳头水肿发生的机理乳头水肿最主要原因是颅内压增高。为什么颅内压增高容易引起乳头水肿昵?对此问题首先应从解剖生理学方面加以阐述。视网膜的动脉、静脉均从视神 Optic Nerve Edema Optic Nerve Head Edema (papillary edema) refers to the non-inflammatory changes in the papillae passively produce edema, clinically called congestion nipple, is a common clinical symptom, more than 80% is Due to intracranial disease caused by increased intracranial pressure caused by a very important diagnostic significance. First, the mechanism of papilla edema The most important reason for papillary edema is increased intracranial pressure. Why increased intracranial pressure easily lead to nipple edema? This question should first be anatomically and physiologically elaborated. Retina arteries, veins are from the optician
