概括
光谱域光连贯性断层扫描 (SD-OCT) 显示,在患有开角玻璃眼 (OAG) 或眼高血压 (OHT) 的中国患者中,虹膜角膜角测量有显著的变异性. 超过三分之一的患者的视角过于狭窄,无法进行青光眼管分路,这突出了SD-OCT.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
背景情况:
- 视角大眼镜 (OAG) 和眼睛高血压 (OHT) 是常见的疾病,需要仔细的手术前评估.
- 精确测量虹膜角生物识别对于手术规划至关重要,特别是对于青光眼设备的选择.
研究的目的:
- 为了比较前段光谱域光学连贯性断层扫描 (SD-OCT) 生物识别与Shaffer等级的临床评估.
- 确定在中国患有OAG或OHT的患者手术前角度评估最合适的方法.
主要方法:
- 一项前性,非干预性研究,涉及206名患有OAG或OHT的中国患者.
- 进行了Shaffer分级和SD-OCT扫描下部虹膜角的下部角.
- 在施瓦尔贝直线 (SL-AOD) 上的角度开放距离使用可分级 SD-OCT 图像上的 ImageJ 软件进行测量.
主要成果:
- 大多数眼睛都有3或4级的沙弗角.
- 平均SL-AOD为0.75毫米,观察到显著的变化 (范围为0.051-1.9毫米).
- 37.6%的眼睛的SL-AOD小于0.635毫米,不足以用于常见的青光眼管短路.
结论:
- 在中国患有OAG/OHT的患者中,SD-OCT对虹膜角的测量显示出相当大的变化.
- 很大一部分患者的视角过于狭窄,无法使用标准的绿眼镜管植入物.
- 手术前的SD-OCT可以识别有风险的角度,潜在地预防并发症和指导设备选择.

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...

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...
