概括

患有多发性糖尿病视网膜病变 (PDR) 的术后视敏与OCT血管学发现有关. 表面和深层毛细血管的血管密度和长度减少与较差的结果相关.

科学领域:

眼科医生眼科眼科
医疗成像医学成像
糖尿病视网膜病变研究研究

背景情况:

糖尿病视网膜病变 (DR) 是导致视力丧失的主要原因.
扩散性糖尿病视网膜病变 (PDR) 涉及新血管化,并可能导致严重的视力障碍.
光学连贯断层扫描血管学 (OCTA) 提供了详细的微血管成像.

研究的目的:

评估糖尿病视网膜病变治疗后视力敏度和OCT血管学参数之间的相关性.
为了确定影响PDR患者治疗后视觉结果的因素.

主要方法:

一组89只眼睛 (42个非PDR,47个PDR视体切除术后) 接受了OCTA.
使用Python和FIJI进行图像分析.
多变量线性回归分析了PDR中最佳校正视敏度 (BCVA) 和OCTA参数之间的关联.

主要成果:

与非PDR眼相比,PDR眼的血管密度 (VD),血管长度密度 (VLD) 和深毛细血管 (DCP) 和胆毛细血管 (CCP) 的碎形尺寸 (FD) 显著较低.
在术后BCVA和SCP参数 (VD,VLD,FD) 之间发现了负相关性.
DCP和CCP参数 (VD,VLD,血管曲度,流量空隙数量) 也与术后BCVA负相关.

结论:

在PDR中术后视力敏度与OCTA检测到的微血管变化有关.
表面毛细管 (SCP),深毛细管 (DCP) 和胆毛细管 (CCP) 中特定的OCTA参数可以预测视觉结果.

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...

Diabetic Retinopathy

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...
