- 了解iAMD的进展,特别是视敏度 (VA) 的变化,对于患者的管理至关重要.
- 微妙的结构变化,如不完整的视网膜和视网膜色素缩 (iRORA) 和子视网膜状体沉积物 (SDD),可能会影响iAMD的进展.
研究的目的:
- 评估与中期年龄相关黄斑变性 (iAMD) 的参与者视力敏度 (VA) 的两年变化.
- 根据存在或不存在不完整的视网膜和视网膜色素缩 (iRORA) 和子视网膜形沉积物 (SDD) 来对iAMD参与者进行分类.
- 分析这些特定的iAMD亚型在24个月的时间内如何影响VA下降.
主要方法:
- 一项多中心队列研究,涉及805名患有iAMD (983只眼睛) 的参与者.

Photoreceptors and Visual Pathways
8.7K
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
1.2K
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
958
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.
