概括
与年龄相关的非麻性高 (ARNH) 涉及比正常个体更大的循环扭转. 这一发现挑战了典型的眼综合征呈现,表明减少融合能力可能导致双眼视.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
背景情况:
- 与年龄相关的非麻性高 (ARNH) 与眼综合征有关,其特征是显著的外,通常在下眼部更大.
- 了解ARNH的临床特征和循环扭转模式对于诊断和管理至关重要.
研究的目的:
- 详细说明诊断为ARNH的患者的临床特征.
- 量化比较ARNH患者的循环扭转与健康个体的对照组.
主要方法:
- 这项研究包括75名ARNH患者 (在50岁后被诊断为潜伏的距离双眼视,非麻性超偏差和>6个月的随访) 和75名年龄/性别匹配的对照.
- 客观循环扭转被测量使用从底部照片的圆盘到叶角 (DFA).
主要成果:
- 患有RNAH的患者的平均超度为4.6±2.8镜二光.
- 与对照组 (6.6-9.2°) 相比,ARNH组 (11.0-11.6°) 的圆盘到叶角 (DFA) 显著更大,p < 0.0001.6°.
- 在非主导眼睛 (12.5°) 与主导眼睛 (10.2°) 中观察到较大的DFA,39%的ARNH患者在下眼中没有显示出更大的勒索.
结论:
- 在ARNH患者中,超偏差的程度通常很小.
- 与正常人相比,ARNH患者的循环扭转增加.
- 在ARNH病例中,下眼频繁缺少较大的,与典型的眼综合征呈现有所不同,这表明,光适应性减弱可能会导致双眼视.

Alterations in Blood Pressure
1.2K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Photoreceptors and Visual Pathways
6.0K
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,...

Glaucoma: Overview
565
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...

Open Angle Glaucoma: Treatment
440
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.

Parkinson's Disease: Overview
541
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Angle Closure Glaucoma: Treatment
485
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...
