概括

鼻管阻塞 (NLDO) 通过改变眼部微生物群,增加了眼部手术后的感染风险. 在手术前管理NLDO至关重要,以预防严重的并发症,如内眼炎.

科学领域:

眼科医生眼科眼科
微生物学微生物学

背景情况:

鼻管阻塞 (NLDO) 显著影响眼睛表面的微生物群.
这种改变涉及增加的细菌负载,多微生物殖民和耐药生物体,增加眼内外科手术并发症的风险.

研究的目的:

研究NLDO对眼睛表面微生物群的影响.
评估这些微生物转移对术后内炎风险的影响.
在眼内外科手术的背景下评估NLDO的管理策略.

主要方法:

关于NLDO和眼睛表面微生物组的文献综述.
对有或没有NLDO患者的结膜培养阳性率的分析.
诊断测试的评估,如催囊 (ROPLAS) 压力反测试.
对达克里西斯托利诺斯托米 (DCR) 治疗结果和替代管理策略的评估.

主要成果:

与正常眼睛 (40%) 相比,NLDO患者表现出较高的结膜培养阳性 (高达100%).
病原性细菌,如 Pseudomonas aeruginosa 和 Streptococcus pneumoniae 在NLDO患者中更为普遍.
达克里奥西斯托利诺斯托米 (DCR) 有效地降低了微生物负担,在术后大约4周内,菌群正常化.

结论:

由于微生物组的改变,NLDO对术后内炎的风险很大.
术前查和NLDO的管理对于减轻感染风险至关重要.
虽然DCR是有效的,但由于潜在的残留微生物组变化,需要持续保持警.

关键词:

Glaucoma: Overview

Glaucoma: Overview

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

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...
