概括
在具有不对称视野损失的初级视角闭眼 (PACG) 中,较差的眼睛通常具有较薄的中央角膜厚度 (CCT) 和较高的眼内压力 (IOP). 这些发现突出了不对称的PACG患者眼睛的差异.
科学领域:
- 眼科医生 眼科 眼科
- 玻璃眼研究研究 玻璃眼研究
- 临床眼科 临床眼科
背景情况:
- 主要角闭眼光眼 (PACG) 是视力丧失的重要原因.
- 了解PACG的整眼差异对于诊断和管理至关重要.
- 不对称的视野损失在PACG中很常见,但其潜在的生物识别相关性需要进一步调查.
研究的目的:
- 为了比较初级角闭眼光眼 (PACG) 患者的整眼临床和生物识别参数.
- 为了研究在呈现时具有不对称和对称视野损失的眼睛之间的差异.
主要方法:
- 对243名PACG受试者的回顾性研究.
- 提取的数据包括眼内压力 (IOP),视镜,视野平均偏差 (MD),中枢角膜厚度 (CCT),前腔深度 (ACD) 和轴长度 (AL).
- 不对称的PACG定义为眼间视野MD差异>6dB;对称的PACG<3dB. 使用线性混合效应模型.
主要成果:
- 50.3%的受试者有不对称的PACG,28.4%的受试者有对称的PACG.
- 在不对称的PACG中,较差的眼睛显示出明显更高的呈现IOP,更窄的角度,更多的近视折射和较薄的CCT,相比于其他眼睛.
- 在两组中都没有观察到轴长或前腔深度的眼睛间显著差异. 在对称的PACG中,只有呈现IOP的眼睛在最坏的眼睛中更高.
结论:
- 在不对称的PACG中,较差的眼睛的特征是较薄的中央角膜厚度 (CCT) 和更高的眼内压力 (IOP).
- 中央角膜厚度是解释视野平均偏差在不对称组中较差眼睛变化的唯一显著变量.
- 在CCT中观察到的差异可能是固有的或获得的,需要进一步调查.

Glaucoma: Overview
496
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...

Angle Closure Glaucoma: Treatment
432
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...

Open Angle Glaucoma: Treatment
386
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.
