Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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...

概括

没有外周 iridotomy (PI-less) 的 Descemet 膜内皮质角质整形 (DMEK) 显示出有前途的结果. 没有PI的三重DMEK可能会提高可访问性和降低成本,但建议密切监测眼内压力 (IOP).

关键词:

在 DMEK DMEK 里面.没有PI-less的PI.脱落膜内皮膜内皮膜内皮质塑.没有外围 iridotomy 的情况.瞳孔扩展的眼滴可以使瞳孔扩大.

科学领域:

眼科医生眼科眼科
角膜外科手术角膜外科手术
内皮皮质生化.

背景情况:

德斯梅特膜内皮皮质角质整形 (DMEK) 是治疗内皮功能障碍的一种手术程序.
周围皮质切除术 (PI) 经常与DMEK一起进行,以防止瞳孔堵塞.
在没有PI的情况下使用DMEK后的水性眼滴需要对安全性和有效性进行调查.

研究的目的:

为了评估临床结果,特别是眼内压力 (IOP) 变化和移植活力,在PI-less DMEK后使用水性眼滴.
评估在患有福克斯内皮角膜缩症 (FECD) 和状角膜病变 (BK) 的患者中不含PI的DMEK的安全性和有效性.

主要方法:

一项回顾性观察性临床研究包括41名接受PI-less DMEK的患者 (44只眼睛).
患者接受了标准的PI-less DMEK或PI-less三重DMEK,以及术后的脑水滴眼液 (烯和热胺).
测量结果包括最佳校正的视力敏度 (BCVA),内皮细胞密度 (ECD) 和IOP,平均随访时间为16个月.

主要成果:

在两组PI-lessDMEK组中都观察到BCVA的显著改善.
在两组中,内皮细胞密度在术后显著下降.
术后第一天眼内压力显著下降,在6个月后没有显著的群体间差异.

结论:

没有PI的DMEK与水性眼滴显示了关于IOP和移植活性的有希望的结果.
没有PI的三重DMEK可能在可访问性和成本效益方面提供优势,特别是在资源有限的环境中.
建议对接受PI-less DMEK的患者进行密切的术后IOP监测.
