概括
外鼻黄斑 perfusion 密度 (MPD) 的降低与初级开角玻璃眼 (POAG) 中视野敏感度的恶化有关. 这一发现突出了MPD.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 玻璃眼研究研究 玻璃眼研究
背景情况:
- 主要开角光眼 (POAG) 是不可逆转失明的主要原因.
- 评估青光眼的进展通常依赖于视野 (VF) 测试和结构光学连贯性断层扫描 (OCT) 测量.
- 需要补充成像生物标志物来监测疾病的进展,特别是在晚期.
研究的目的:
- 通过OCT血管造影 (OCTA) 测量的部门黄斑 perfusion 密度 (MPD) 和中央视野 (VF) 灵敏度 (汉弗里10-2) 之间的关系.
- 为了分析初级开角青光眼 (POAG) 的不同阶段之间的这种关系:轻度,中度和高级.
主要方法:
- 一个追溯的横截面研究涉及196只眼睛与POAG.
- 使用OCTA (6x6毫米表面) 量化了部门MPD.
- MPD与汉弗雷10-2视野测试的总偏差 (TD) 的总和相关,并映射到相应的OCTA部门. 用30-2平均偏差 (MD) 来分类青光眼的严重程度.
主要成果:
- 外鼻MPD显示从轻度到严重的POAG (46.7%到39.6%) 的逐步下降.
- 外鼻MPD与中央10-2 TD总和显著相关 (r=0.364,P<1×10‒7) 并在中度 (r=0.298,P=0.013) 和严重 (r=0.286,P=0.022) 阶段内.
- 多变量分析表明,外鼻MPD (β=0.513,P<0.001) 和黄斑结节细胞内层 (mGCIPL) 厚度 (β=0.288,P<0.001) 独立地与10-2MD相关,而环皮状视网膜神经纤维层 (cpRNFL) 厚度则没有.
结论:
- 在所有严重程度的POAG中,减少外鼻MPD与中心功能视力损失密切相关.
- 外鼻MPD提供了对mGCIPL厚度的补充信息,用于监测玻璃眼.
- 对于评估青光眼的进展来说,OCTA是一个有价值的辅助工具,特别是当结构性OCT测量接近其极限时,包括在晚期疾病阶段.

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
928
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.

Angle Closure Glaucoma: Treatment
1.1K
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...
