概括
自发的光盘出血可以发生在周边皮囊超反射卵状质量样结构 (PHOMS) 中. 图像显示了PHOMS特征和潜在的微血管参与光盘拥堵.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
背景情况:
- 光盘的自发焦点出血是一种罕见的疾病.
- 周周的超反射性卵状质量样结构 (PHOMS) 具有特定的成像发现的特点.
研究的目的:
- 报告两例罕见的与PHOMS相关的自发光盘出血的成像特征.
- 为了研究PHOMS和光盘出血之间的关系.
主要方法:
- 两名患者的病例报告自发光盘出血和PHOMS.
- 使用彩色底部摄影 (CFP),底部自光 (FAF),光谱域光学连贯性断层扫描 (SD-OCT),光学连贯性断层扫描血管学 (OCTA) 和最小强度投影 (Min-IP) 成像.
主要成果:
- 这两种病例都呈现出光盘上小小的斑块性出血.

Anatomy of the Eyeball
6.1K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Glaucoma: Overview
519
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...
