概括
减压手术可以改善视觉路径压缩的患者的视力. 然而,光学连贯断层扫描 (OCT) 和OCT血管扫描 (OCTA) 显示视网膜结构和血管密度在手术后下降,表明轴突损失.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
背景情况:
- 压缩前视通路病变可能会损害视力.
- 在解压术后,视网膜血管密度的纵向变化尚未得到充分理解.
研究的目的:
- 用OCT和OCTA来研究视网膜血管系统的术后变化.
- 确定OCT和OCTA参数在去压缩手术后视觉结果的预测值.
主要方法:
- 对22只眼睛 (15名患者) 进行前视觉通路损伤的前性研究.
- 在手术前和1,3,6个月后对视敏度,视野和OCT/OCTA参数 (RNFL,GCC,血管密度) 的评估.
主要成果:
- 术后1个月视力敏度和视野显著改善.
- 从1到6个月显著减少视网膜神经纤维层,质细胞综合体 (GCC) 厚度和辐射周毛细血管密度.
- 手术前的GCC厚度预测视力敏度的改善;<70微米的GCC与更糟糕的结果有关.
结论:
- 减压手术改善了视觉功能,尽管OCT/OCTA检测到的逆行性退行和血管重塑.
- GCC 厚度是视觉预后的潜在预测因素,应定期评估.

Open Angle Glaucoma: Treatment
1.0K
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.

Glaucoma: Overview
1.5K
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
1.4K
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...
