概括

糖尿病黄斑 (DME) 的静脉内类固醇治疗减少了黄斑厚度波动 (MTF),但没有改善视力敏度. 这表明MTF变化可能无法预测DME患者的类固醇治疗的结果.

科学领域:

眼科医生眼科眼科
视网膜疾病视网膜疾病
糖尿病视网膜病变 - 糖尿病视网膜病变

背景情况:

斑点厚度波动 (MTF) 可以预测使用抗VEGF疗法治疗糖尿病斑点 (DME) 的视觉结果.
在预测DME患者用静脉内类固醇治疗的结果中MTF的作用尚不清楚.
与抗VEGF治疗相比,如果类固醇可以减少MTF,仍然不清楚.

研究的目的:

在接受内类固醇治疗的糖尿病黄斑胀 (DME) 患者中调查黄斑厚度波动 (MTF).
为了确定MTF变化是否与DME患者在类固醇启动后的视力敏度结果相关.

主要方法:

在DME患者的静脉内类固醇启动前和后的MTF比较.
使用混合效应线性回归模型来分析MTF和最佳校正视敏度 (BCVA) 之间的关联.

主要成果:

平均12个月的MTF显著减少后类固醇启动 (61.1微米到53.5微米,P=0.04).
12个月后的BCVA平均值与基线没有显著差异.
在后类固醇MTF和12个月BCVA之间没有发现显著的关联.

结论:

静脉内类固醇治疗导致DME患者的MTF显著下降.
尽管MTF减少,但最佳校正视敏度 (BCVA) 保持稳定,这表明MTF可能不是在DME中使用类固醇对视觉结果的预测标记.

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

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...
