概括

光道综合征,由光道病变引起的,经常呈现与不相称的同名 Hemianopia. 这项研究突出了各种临床和成像发现,强调需要考虑在患有微妙视野缺陷的患者眼道病变.

科学领域:

神经眼科神经眼科
神经科学是一个神经科学.
放射学放射学是一门学科.

背景情况:

光道综合征的文献有限.
了解各种临床和成像表现非常重要.

研究的目的:

阐明光道综合征的临床和成像表现.
与致病性损伤类型相关联的表现.

主要方法:

对56名患有视觉管综合征的患者进行了回顾性队列研究 (2014-2024年).
纳入标准:视觉通道综合征的迹象和确认的视觉通道损伤.
分析临床数据,视野和周周细胞光学连贯性断层扫描 (OCT).

主要成果:

常见的病因:占空间的病变 (25),脱髓化 (11),缺血/出血 (9).
98%的视野缺陷,主要是不完整和不一致的同名视力缺陷 (78%).
周周的OCT在41%的患者中显示了带/沙表缩; 脱髓化病变不太可能显示缩.

结论:

在患有不完整,不一致的同名缺陷的患者中,应考虑视觉通道病变.
带/沙表缩的周周皮质OCT是有价值的,但在去髓化病例中可能不太常见.

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...
