概括

长期影响眼膜脂层厚度和眼模式. 在手术后至少持续6个月的角膜免疫活动.

科学领域:

眼科眼科
角膜外科手术
眼部表面疾病

背景情况:

德塞米特膜内皮角膜整形术 (DMEK) 是一种用于角膜内皮功能障碍的手术.
了解手术后眼睛表面的变化对于患者的治疗至关重要.

研究的目的:

调查DMEK后膜和眼睛表面参数的变化.
为优化DMEK后的临床干预提供见解.

主要方法:

研究了84名接受角膜内皮功能障碍 (CED) 的患者队列.
眼脂层厚度 (LLT),眼率和体内共聚焦显微镜 (IVCM) 的评估在手术前和后进行.
IVCM评估了上皮翼细胞,白细胞和底层树突细胞 (DC).

主要成果:

在DMEK后,在LLT和眼模式中观察到显著变化,长达36个月.
在CED患者中,白细胞密度的增加与视觉敏度和上皮细胞的减少相关.
在DMEK治疗6个月后,基底下DC密度仍然较高.

结论:

眼睛表面异常,包括膜变化,可以在DMEK后的不同阶段表现出来.
在DMEK治疗后至少6个月内,角膜免疫活性保持高.

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...
