视交叉蛛网膜炎和鞍旁脑膜瘤是引起失明的原因之一。前者是脑膜和脑实质表面弥漫性炎症,主要侵犯大脑基底池、视神经和视交叉的脑膜;后者是良性肿瘤,起源于鞍结节、蝶骨小翼、前床突及视神经管处的蛛网膜。它们的鉴别诊断最为困难,且治疗又完全不同。鞍旁脑膜瘤于视力损害的早期确诊者不超过4％,其余96％在几个月至几年中都误诊为视神经萎
Astigmatism and paraselella meningioma are one of the causes of blindness. The former is diffuse diffuse inflammation of the meninges and brain parenchyma, mainly invading the basal ganglia of the brain, the optic nerve, and the optic chiasm; the latter is a benign tumor, originating from saddle nodes, sphenoid winglets, anterior biceps, and cobwebs at the optic canal. membrane.
