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.
- 冠状腺变化,包括稀薄和血管变化,都与AMD的发病有关.
- 了解这些变化对于监测疾病进展至关重要.
研究的目的:
- 为了研究不同阶段的眼睛中胸膜厚度 (CT) 和胸膜血管度指数 (CVI) 的纵向变化.
- 为了将这些变化与健康的对照眼睛进行比较.
- 为了确定基线CT和CVI是否可以预测AMD进展.
主要方法:
- 对105只眼睛进行了回顾性纵向研究 (46个非晚期的AMD,28个排泄性AMD,5个中央cRORA,26个健康对照).
- 在基线和2至4年的随访期间对CT和CVI的评估.
- 包括每年变化率和AMD进展预测后勤回归在内的统计分析.
主要成果:
- 健康的眼睛表现出比AMD眼睛更高的基线CT和CVI.
- 排泄性AMD眼睛显示,亚叶CT (-5.1%) 和部门CT (-5.3%至 -6.3%) 的年均显著下降.
- 在所有组中,每年CVI都在下降,在中部cRORA眼中观察到的最显著的减少 (-1.09%).
结论:

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
