在早期或中期的与年龄相关的黄斑变性 (AMD),不完整的视网膜色素表皮和外视网膜缩 (iRORA) 和获得的形病变 (AVL) 在两年内显著增加进展到晚期AMD的风险.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 遗传学 遗传学 是一个
背景情况:
- 与年龄相关的黄斑变性 (AMD) 是导致视力丧失的主要原因.
- 光学连贯断层扫描 (OCT) 对于识别AMD生物标志物至关重要.
- 早期检测和风险分层对于管理AMD进展至关重要.
研究的目的:
- 在阿米什人群中确定关键的OCT生物标志物的流行率,这些人患有早期到中期的AMD.
- 评估与这些生物标志物相关的晚期AMD进展的两年风险.
- 为了确定特定的OCT发现,预测AMD的进展.
主要方法:
- 这是一项针对171名阿米什人 (276只眼睛) 的前性,纵向,基于人口的队列研究.
- 基线的OCT扫描分析了皮质干燥,获得的形病变 (AVLs),子皮干燥沉积物 (SDD) 和其他特征.
- 在两年内使用多式成像监测到晚期AMD (地理缩或新血管化) 的进展.
主要成果:
- 10.7%的眼睛在两年内发展为晚期AMD.
- 皮干是最常见的 (52.3%),但与进展无显著关联.
- 视网膜色素表皮不完整和外视网膜缩 (iRORA) 和AVL独立地与进展风险增加有关.
结论:
- iRORA和AVL是晚期AMD进展的重要独立预测因素.
- 皮干,尽管患病率很高,但在这个队列中没有显示出与AMD进展的显著关联.
- 通过监测iRORA和AVL,可以改善AMD进展的风险分层.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
