概括
环皮状视网膜神经纤维层 (RNFL) 和布鲁赫神经纤维层之间的差异.
科学领域:
- 眼科医生 眼科 眼科
- 玻璃眼研究研究 玻璃眼研究
- 视网膜成像分析分析
背景情况:
- 青光眼的诊断依赖于结构测量,如RNFL和BMO-MRW.
- 了解这些措施之间的差异对于准确的青光眼评估至关重要.
研究的目的:
- 为了比较环状毛囊RNFL和BMO-MRW厚度在青光眼患者之间的差异.
- 为了确定RNFL和BMO-MRW测量之间的不匹配的流行和解剖原因.
主要方法:
- 从118名青光眼患者的186只眼睛进行了横截面观察研究.
- 分析OCT视神经头部扫描,使用两阶段选过程来识别RNFL/BMO-MRW不匹配.
- 绘制不匹配位置的地图并审查图像以确定潜在的解剖原因.
主要成果:
- 在7.7%的行业中发现了RNFL和BMO-MRW之间的真正不匹配.
- 高RNFL/低BMO-MRW不匹配在75°部门达到顶峰,通常是由于大血管 (90.9%).
- 高BMO-MRW/低RNFL不匹配发生在45°和322.5°部门,归因于血管,视网膜分裂或视网膜外层的入.
结论:
- 虽然RNFL和BMO-MRW在晚期青光眼中显示出很好的一致性,但解剖学因素导致差异.
- 血管和其他结构可能导致不匹配,因此在检测结构变化时需要考虑.

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...

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...
