- 视网膜疾病 视网膜疾病
- 与年龄相关的斑点退化症
背景情况:
- 神经血管与年龄相关的黄斑变性 (AMD) 对视力构成重大威胁.
- 识别响应较差的AMD视力衰退的预测因素对于有效的管理至关重要.
研究的目的:
- 描述响应较差的新血管AMD的自然史.
- 为了跟踪这些患者的结构变化和视力敏度随着时间的推移而下降.
主要方法:
- 对70个未接受过治疗的新血管AMD眼睛进行了回顾性纵向研究.
- 分析光谱域OCT成像和最好的视力敏度 (BCVA) 校正在基线,10个字母的损失,和最差的结果.
- 多变量回归以确定视力敏度的预测因素,评估黄斑缩,膜纤维化,ELM/EZ完整性,CRT和流体.
主要成果:
- 随着时间的推移,黄斑缩和子纤维化显著增加 (p < 0.001).
- 中央视网膜厚度 (CRT) 显示出一种矛盾的双相演变.

Photoreceptors and Visual Pathways
9.5K
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
1.4K
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
1.0K
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.
