Abstract

.The guest editorial provides an introduction to the Special Section on Advanced Retinal Imaging: Instrumentation, Methods, and Applications.

Highlights

  • The retina is a peripheral part of the central nerve system (CNS) and shares many similarities with the cerebral cortex

  • Because the human retina is directly accessible by light, optical retinal imaging is a unique field that brings together biology, engineering, data science, and clinical applications, creating a highly dynamic, sustainable, and vibrant ecosystem

  • The strong spectral contrast of hemoglobin in visible wavelength allows the quantification of hemoglobin oxygen saturation, and the inner retinal oxygen metabolism when combining Doppler blood flow measurements

Summary

Introduction

The retina is a peripheral part of the central nerve system (CNS) and shares many similarities with the cerebral cortex. Approximately 80 percent of information from the outside world is processed as visual perception,[1] and retina-related blindness is a significant disabling condition that poses a huge healthcare burden worldwide.[2] Because the human retina is directly accessible by light, optical retinal imaging is a unique field that brings together biology, engineering, data science, and clinical applications, creating a highly dynamic, sustainable, and vibrant ecosystem. This special section of Neurophotonics Volume 6, Issue 4, testifies to such an ecosystem, encompassing a broad range of topics in instrumentation, methods, and applications for advanced retinal imaging.
