背景情况:
- 韦斯特综合征是一种严重的婴儿.
- 维加巴是一种常见的抗发作药物.
- 视神经异常是一种已知的vigabatrin副作用.
研究的目的:
- 用扩散张力成像 (DTI) 评估用vigabatrin治疗韦斯特综合征的儿童的视神经损伤.
- 为了识别vigabatrin诱导的视神经损伤的成像生物标志物.
- 评估这些变化的可逆性.
主要方法:
- 对35名患有韦斯特综合征的儿童进行了回顾性分析.
- 根据vigabatrin治疗和胸膜异常进行分组.
- 使用DTI. 评估视神经分数异构性 (FA) 和明显扩散系数 (ADC).
- 接收器操作特征 (ROC) 曲线分析以确定FA损伤值.
主要成果:

01:27Open Angle Glaucoma: Treatment
579
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.

01:28Angle Closure Glaucoma: Treatment
697
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...

01:25Glaucoma: Overview
775
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...
