Multimodal Imaging of the Normal Eye

ABSTRACT

Multimodal imaging is the concept of “bundling” images obtained from various imaging modalities, viz., fundus photograph, fundus autofluorescence imaging, infrared (IR) imaging, simultaneous fluorescein and indocyanine angiography, optical coherence tomography (OCT), and, more recently, OCT angiography. Each modality has its pros and cons as well as its limitations. Combination of multiple imaging techniques will overcome their individual weaknesses and give a comprehensive picture. Such approach helps in accurate localization of a lesion and understanding the pathology in posterior segment. It is important to know imaging of normal eye before one starts evaluating pathology.

This article describes multimodal imaging modalities in detail and discusses healthy eye features as seen on various imaging modalities mentioned above.
