概括
视神经减压可以有效地改善脑脊液 (CSF) 流动障碍患者的视力,即使没有增加的内压力. 这种方法为手术资格提供了一个新的框架,扩大了CSF相关的视神经病变的治疗选择.
科学领域:
- 眼科医生 眼科 眼科
- 神经外科 神经外科
- 神经学 神经学
背景情况:
- 脑脊液 (CSF) 流动障碍可能导致逐渐视力受损.
- 目前手术干预的诊断标准通常依赖于异常性内高血压 (IIH) 诊断.
- 需要客观的措施来指导CSF相关的视神经病变的外科资格.
研究的目的:
- 在患有CSF流动障碍的患者视神经减压后评估长期视觉结果.
- 提出一个使用CSF输液测试和轨道MRI进行手术资格的机制框架.
- 评估视神经减压的疗效,独立于IIH诊断标准.
主要方法:
- 在26名视力受损和CSF流异常的患者中对30只眼睛进行了回顾性分析.
- 标准化腰部输液试验,以量化CSF外流阻力,压力体积指数和开口压力.
- 轨道核磁共振扫描 (MRI) 用于评估视周脑脊髓液 (CSF) 收集或视通道狭窄.
- 通过视神经外围膜化 (ONSF) 或内镜视神经外围膜解压 (EONSD) 的手术干预.
- 视觉功能评估使用视觉场,视觉唤起的潜能和RNFL厚度在基线和24个月.
主要成果:
- 在24个月内,视野平均偏差 (+1.89 dB) 显著改善,P100延迟 (-5毫秒) 减少.
- 在87.5%的受影响眼睛中,皮囊的消失.
- 视网膜神经纤维层 (RNFL) 厚度保持稳定或增加,在EONSD后趋向于更大的加厚.

Glaucoma: Overview
1.2K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment
1.1K
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...

Open Angle Glaucoma: Treatment
934
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
