概括

没有压力的黑暗 (DWOP) 是高近视的常见现象,出现在下腔中端外周. 这个视网膜特征是视网膜的特征.

科学领域:

眼科医生眼科眼科
视网膜成像视网膜成像
近视研究近视研究

背景情况:

没有压力的黑暗 (DWOP) 是一个研究不足的视网膜特征.
近视是一个日益严重的全球健康问题.
先进的成像技术对于了解视网膜病理至关重要.

研究的目的:

确定近视个体中DWOP的发生率和分布.
为了利用超广场扫描源光学连贯性断层扫描血管学 (UWF-SS-OCTA) 和超广场色底摄影 (UWF CFP).
为了将DWOP发生与近视严重程度相关联.

主要方法:

从2021年12月到2024年5月,招募了304名受试者 (592只眼睛).
进行了全面的眼科检查,包括UWF CFP和UWF-SS-OCTA.
根据球体等价值 (SE) 将眼睛分类为凝视,轻度,中度和高近视.

主要成果:

总体而言,DWOP发生率为25.5%,高近视 (44.3%) 与血液缩小 (10.9%) 相比显著更高.
与轴长>26mm和SE < -6.0 D.相关的DWOP风险增加
在DWOP区域中,视网膜的厚度减少;在DWOP区域中,视网膜的厚度减少.

结论:

在高近视症中,DWOP是普遍存在的,主要是在内末端的中端外围.
DWOP边界表现出时间变化.
需要进一步研究近视期DWOP进展的临床意义.

Focusing of Light in the Eye

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
