概括
角膜交叉链接 (CXL) 改善了角质患者的眼睛症状,但没有显著改变梅博米腺 (MGs) 或膜稳定性. 这表明CXL主要针对角膜变化,而不是眼睛表面环境.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 眼睛表面疾病 眼睛表面疾病
背景情况:
- 角膜是一个逐渐稀薄的角膜,往往导致不规则的眼和视力减弱.
- 角膜交叉链接 (CXL) 是一种标准的治疗方法,用于阻止角膜的进展.
- 需要进一步调查CXL对眼睛表面的影响,包括梅博米腺 (MGs) 和膜.
研究的目的:
- 为了评估梅博米腺 (MGs) 和眼表面参数在角膜交叉链接 (CXL) 后发生的变化.
- 评估CXL对视敏度,折射误差和角膜拓学的影响.
- 确定CXL对眼表面疾病指数 (OSDI) 和非侵入性撕裂破裂时间 (NI-TBUT) 的长期影响.
主要方法:
- 一项前性研究包括48名形患者的48只眼睛,这些患者接受了CXL.
- 在手术前和CXL后的1,3,6和12个月内,Meibography评估了meibomian腺体 (MGs).
- 视力敏度,折射误差,角膜断层扫描,OSDI和非侵入性撕裂破裂时间 (NI-TBUT) 被记录下来.
主要成果:
- 角膜断层扫描 (K1,K2,Kmean,Kmax) 在CXL后显著改善 (p<0.001).
- 视敏度和折射误差在CXL后保持稳定.
- 梅博米腺 (MG) 形态和非侵入性撕裂破裂时间 (NI-TBUT) 没有显著变化,而OSDI得分显著下降 (p<0.001).
结论:
- 角膜交叉连接 (CXL) 有效地稳定了角质的进展,并改善了主观的眼部症状.
- 长期来看,CXL不会显著影响梅博米腺 (MG) 结构或膜稳定性.
- 在CXL后,眼部症状的改善可能归因于角膜不规则性减少,而不是对眼睛表面的直接影响.

Glaucoma: Overview
1.7K
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
1.7K
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...

Microbiome of the Eye
75
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Acute Pancreatitis II: Pathophysiology
49
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...

Chronic Pancreatitis II: Pathophysiology
35
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
