- 眼科医生 眼科 眼科
- 生物识别仪表是如何使用的
- 角质地形图 角质地形图
背景情况:
- 白内障手术需要准确的标性评估,以获得最佳的视觉结果.
- 标准角膜测量可能无法完全捕捉出全角膜纹症 (TCA).
研究的目的:
- 在接受白内障手术的患者中确定全角膜白症 (TCA) 的患病率和特征.
- 为了比较通过不同的方法获得的TCA测量.
主要方法:
- 从10,817名白内障手术患者的手术前生物识别数据的回顾性分析.
- 使用IOLMaster 700,Abulafia-Koch (AK) 公式和巴雷特托里克计算器测量TCA.

Glaucoma: Overview
560
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...

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,...
