: Retromode is a relatively new retinal-imaging technique that is based on the transillumination principle and is obtained with a scanning laser ophthalmoscope that uses light in the infrared spectrum. The laser light penetrates into the deep retinal layers and the choroid. Retromode images are captured with a laterally displaced aperture, and the detector captures only the scattered light. The result is a high-contrast pseudo-three-dimensional image. Age-related macular degeneration (AMD) is a disabling retinal disease. AMD is characterized in its early stage by small and intermediate drusen formation, while the signs of intermediate AMD are large drusen and/or pigmentary abnormalities. Late AMD has two forms, geographic atrophy, which is the advanced form of dry AMD, and wet AMD. Most of the lesions of AMD are located in the outer layers of the retina. This new imaging method can provide a glimpse of the deep retinal layers' topographic changes in a non-invasive, fast, and effective way that can match the other imaging tools available. : The literature review was performed by searching the PubMed database using the following combination of keywords: retromode imaging and age-related macular degeneration. Relevant images similar to the ones in the literature were identified and used as models. : The purpose of this article is to highlight the utility of incorporating retromode imaging into the multimodal evaluation of the retina in patients with AMD and to gather and integrate these findings into a brief but comprehensive paper. Retromode imaging is a good screening, diagnosis, and monitoring tool for patients with AMD.
Retromode 是一种相对较新的视网膜成像技术,基于透射原理,利用近红外光谱的扫描激光检眼镜获得。激光穿透进入深层视网膜和脉络膜。Retromode 图像通过侧向移动的光阑捕获,探测器仅捕获散射光。结果是高对比度的伪三维图像。年龄相关性黄斑变性(AMD)是一种致盲性视网膜疾病。AMD 在早期的特征是小而中等大小的玻璃膜疣形成,而中间 AMD 的迹象是大玻璃膜疣和/或色素异常。晚期 AMD 有两种形式,即地图样萎缩,这是干性 AMD 的高级形式,和湿性 AMD。AMD 的大多数病变位于视网膜的外皮层。这种新的成像方法可以以非侵入性、快速和有效的方式提供对深层视网膜层拓扑变化的一瞥,与其他可用的成像工具相匹配。
文献综述是通过在 PubMed 数据库中使用以下关键词组合进行搜索来完成的:Retromode 成像和年龄相关性黄斑变性。识别并使用与文献中相似的相关图像作为模型。
本文的目的是强调将 Retromode 成像纳入 AMD 患者的多模态视网膜评估中的实用性,并将这些发现收集并整合到一篇简短但全面的论文中。Retromode 成像对 AMD 患者是一种很好的筛查、诊断和监测工具。
