概括
在初级开角青光眼 (POAG) 和伪皮青光眼 (PXG) 中,视野损失与神经纤维层稀释有很强的相关性,而不是表面血管密度的损失.
科学领域:
- 眼科医生 眼科 眼科
- 玻璃眼研究研究 玻璃眼研究
- 光学连贯性断层扫描血管学
背景情况:
- 主要开角青光眼 (POAG) 和伪皮青光眼 (PXG) 是不可逆转失明的主要原因.
- 了解青光眼的微血管和结构变化对于早期诊断和管理至关重要.
研究的目的:
- 为了比较周周和黄斑表面血管密度,周周神经纤维层厚度和POAG和PXG中的内黄斑厚度.
- 为了研究视野障碍和这些眼睛参数之间的关系,在绿眼病患者.
主要方法:
- 光学连贯断层扫描血管学 (OCT-A) 用于分析辐射周毛细血管 (RPC) 密度和表面黄斑血管密度 (SMVD).
- 测量了周周膜视网膜神经纤维层 (pRNFL) 厚度和内界膜到内状层 (ILM-IPL) 厚度.
- 50个POAG眼睛和50个PXG眼睛根据HAP2视野受损标准被分为子组.
主要成果:
- 在POAG和PXG组之间没有发现OCT-A参数的统计学上显著差异.
- 所有测量参数 (pRNFL厚度,RPC密度,SMVD,ILM-IPL厚度) 都在每个组内显著减少,视野损伤增加.
- 在pRNFL厚度和RPC密度 (p=0.893) 之间观察到最强的正相关性.
- 在视野平均缺陷和ILM-IPL厚度 (p=-0.824) 之间发现了最强的负相关性.
结论:
- 玻璃眼中视野损失与视网膜神经纤维层的稀薄更密切相关,而不是表面血管密度降低.
- 这些发现表明,神经纤维层的损失可能会在青光眼的进展中先发生表面的血管变化.

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
961
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.
