概括
光学连贯断层扫描血管造影 (OCTA) 在正常的眼睛,初级角关闭疑似眼睛 (PACS) 和初级角关闭眼睛 (PAC) 没有先前的急性发作时显示出类似的眼球输液. 这表明血管因素不是早期角度关闭疾病的主要问题.
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:
- 急性初级角关闭 (APAC) 尖峰会降低眼球血流.
- 在没有先前的APAC眼睛中,初级闭角 (PAC) 眼睛的眼球输液并未得到充分理解.
- 在没有急性发作史的PAC眼睛中研究输液对于了解疾病进展至关重要.
研究的目的:
- 用光学连贯断层扫描血管学 (OCTA) 评估眼球输液,在正常情况下,可疑的PAC (PACS) 和没有APAC史的PAC眼睛.
- 为了在这些组中比较OCTA特征,包括周包膜输液,流量和黄斑血管密度.
- 为了确定血管因素是否有助于在没有先前急性发作的情况下导致眼睛的视角闭合疾病.
主要方法:
- 一项涉及135名患者 (40-80岁) 的前性横截面研究.
- OCTA用于测量视神经周膜输液,流量和表面视网膜层的斑点血管密度.
- 患者被分为正常,PACS和PAC小组,没有先前的APAC.
主要成果:
- 在正常眼睛,PACS眼睛和PAC眼睛 (P > 0.05) 之间,没有发现周毛囊输液,流量或黄斑血管密度的显著差异.
- 眼内压力 (IOP) 与PAC眼中的视网膜神经纤维层厚度相关,但与 perfusion 参数无关.
- 与PACS眼相比,Humphrey视野测试显示PAC眼中的平均偏差明显较差 (P = 0.02).
结论:
- 没有先前APAC的PAC眼睛显示与正常眼睛和PACS眼睛相似的OCTA perfusion参数.
- 在没有急性发作的情况下,血管因素似乎不是关闭角度疾病的主要驱动因素.
- 尽管有类似的输液,但PAC眼睛的功能障碍可能表明早期的质细胞功能障碍.

01:28Angle Closure Glaucoma: Treatment
697
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...

01:25Glaucoma: Overview
775
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...

01:27Open Angle Glaucoma: Treatment
579
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.
