概括

手术后的腹腔内血瘤 (SDH) 可以通过压缩视觉皮层引起视力损伤. 这种罕见的并发症应考虑在脑外科手术后新出现视力丧失的患者.

科学领域:

神经外科神经外科
眼科医生眼科眼科
神经学神经学

背景情况:

手术后的脑下血瘤 (SDH) 是神经外科手术后的一种已知的并发症.
虽然通常表现为神经缺陷,但视力障碍是一个不太常见的表现.
患有I型奇阿里形和神经膜炎的患者可能会接受大门减压,这是一种带有潜在风险的程序.

研究的目的:

报告一个视力障碍的病例,其次是术后的腹腔内血瘤.
强调在切术后视力障碍的差异诊断中考虑SDH的重要性.
为了说明这种病例的诊断结果和成功的保守管理.

主要方法:

一个案例研究,一个52岁的妇女,为Chiari I型形和Syringomyelia进行大孔解压.
初步诊断的小急性SDH管理保守.
视力障碍的后续发展,通过眼科检查和MRI诊断.
对SDH和视觉症状进行保守治疗的监测.

主要成果:

术后两周,患者出现视力障碍 (右下四眼视障碍).
磁力共振成像证实SDH在后凸度压缩视觉皮层.
保守的管理导致了血液瘤的减少和视力障碍的改善.
尽管存在SDH,但没有发现最初的神经缺陷.

结论:

后凸性SDH可以通过视觉皮层的压缩直接导致视觉障碍.
视力障碍应在骨切割后SDH患者的差异诊断中考虑.
保守的管理可以有效的选择病例的术后SDH呈现与视力缺陷.

Glaucoma: Overview

Glaucoma: Overview

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...

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
