概括

洞穴鼻腔持续性动脉静脉 (CS-dAVF) 可以导致孤立的三神经麻. 这种罕见的呈现突显了在诊断神经麻时需要考虑CS-dAVF的必要性,即使没有典型的眼部症状.

科学领域:

神经科学是一个神经科学.
血管神经学血管神经学
眼科医生眼科眼科

背景情况:

洞穴鼻腔硬性动脉静脉 (CS-dAVF) 通常表现为眼部症状,如亡和双眼视.
孤立的头骨神经麻,特别是三神经麻,是CS-dAVF的不常见表现.

研究的目的:

报告一种罕见的,由CS-dAVF引起的单独的三神经麻病例.
强调在隔离的头骨神经麻的差异诊断中考虑CS-dAVF的重要性.

主要方法:

一个八十多岁的女性呈现急性双眼视的案例研究.
诊断工作包括Bielschowsky头部倾斜测试,磁共振血管学和数字减去血管学.

主要成果:

患者出现了孤立的右三角膜神经麻,没有其他眼部症状.
血管造影证实了CS-dAVF涉及右脑膜低体干,没有皮质静脉逆流.
由于缺乏皮质静脉反流,选择了保守的管理与观察.

结论:

CS-dAVF可以呈现为孤立的三神经麻,这是一个罕见但重要的差异诊断.
脊髓神经长路线对血液动力学压力的脆弱性可能解释了这种选择性麻.
这一案例强调了在无法解释的神经麻中需要进行彻底的血管评估的必要性.

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
