概括
镜辅助的透光轨道切除术 (GATT) 可能会损害角膜内皮细胞,与SLT不同. 考虑GATT的患者在手术前应该有足够的角膜内皮细胞数量.
科学领域:
- 眼科医生 眼科 眼科
- 玻璃眼的手术 玻璃眼的手术
- 角质科学 角质科学
背景情况:
- 青光眼的管理往往需要手术干预.
- 角膜内皮细胞的健康对眼睛的健康和视力至关重要.
- 轨道绕手术越来越多地用于绿眼治疗.
研究的目的:
- 为了评估角膜内皮细胞密度 (CECD) 的短期变化,经过视镜辅助透光轨道切除术 (GATT).
- 为了比较GATT对角膜内皮细胞的效果与选择性激光膜整形 (SLT).
主要方法:
- 一项涉及138名患者 (138只眼睛) 的回顾性比较研究.
- 98名患者接受了GATT,40名患者作为接受SLT的对照组.
- 在手术前和手术后6个月,用镜像显微镜测量角膜内皮细胞密度.
主要成果:
- 在SLT组中,CECD没有出现统计学上显著的变化 (0.1%±0.6%的损失,p>0.967).
- 在GATT小组中,在程序后6个月内,CECD显著下降 (6.2%±9.1%损失,p<0.001).
- 术前眼内压力和药物使用在两组之间是相似的.
结论:
- 与SLT相比,GATT在6个月的随访中导致角膜内皮细胞损伤更大.
- 对于接受GATT的患者,建议对角膜内皮细胞数进行手术前评估.

Glaucoma: Overview
536
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
468
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
422
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.
