概括
在OCT扫描中,超传播缺陷 (hyperTDs) 表明中期与年龄相关的黄斑变性 (iAMD) 的进展风险更高. 即使是小的TD也显著增加了发展视网膜色素上皮质和外视网膜缩的可能性.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 视网膜疾病 视网膜疾病
背景情况:
- 中期与年龄相关的黄斑变性 (iAMD) 是疾病晚期的前体.
- 确定iAMD进展的生物标志物对于及时干预至关重要.
- 光学连贯断层扫描 (OCT) 是评估视网膜变化的关键成像方式.
研究的目的:
- 研究不同大小的超传输缺陷 (hyperTDs) 与iAMD的进展之间的关联.
- 为了确定hyperTDs是否预测不完整的视网膜色素上皮和外视网膜缩 (iRORA) 和完整的RORA (cRORA) 的发展.
主要方法:
- 对来自iAMD患者的OCT数据的回顾性审查.
- 在基线上对胆道面部OCT的超TD (小,中,大) 的评估.
- 在两年后评估iRORA或cRORA的进展情况.
主要成果:
- 任何尺寸的眼睛都有TD超高,与没有TD超高的眼睛相比,对iRORA/cRORA的进展率显著更高 (P<0.001).
- 在眼睛中,小 (41.6),中 (37.4) 和大 (49.9) 的超TD 的进展几率比率显著增加.
- 眼睛有两个或两个以上的超TD有100%的进展率,而没有或有一个眼睛的眼睛的进展率为16.4%.
结论:
- 任何大小的TD都与iAMD进展的风险增加有关.
- 超高TD作为潜在的OCT生物标志物用于识别患有RORA高风险的iAMD患者.
- 早期发现高TD可能有助于监测和管理iAMD进展.

01:27Open 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.

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...
