背景情况:
- 阴性失光症 (ND) 是与袋内眼内镜片 (IOL) 放置相关的视觉障碍.
- 反向光学捕获 (ROC) 是一种预防ND的技术,但它存在后囊变的风险.
- 由透镜上皮细胞增殖引起的PCO通常在手术后2-5年发生,导致视力受损.
研究的目的:
- 报告两例急性,快速进展的PCO在白内障抽取 (CE) 后与ROC.
- 在这些情况下,要突出PCO在手术后两周内早期出现的情况.
- 强调早期检测和经过ROC后PCO管理的重要性.
主要方法:

Glaucoma: Overview
571
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...

Angle Closure Glaucoma: Treatment
499
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...

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,...
