Non-invasive fundus autofluorescence (FAF) imaging visualizes fluorophores at the level of the photoreceptors, the subneurosensory space and the retinal pigment epithelium. It gives important information over and above other imaging techniques. FAF imaging has improved the pathophysiological understanding of various retinal diseases. In combination with fundus photography, fluorescence angiography, optical coherence tomography, and electrophysiological examinations, FAF imaging is useful with regard to diagnostics and monitoring both during the natural course and after therapies. This review highlights basic principles of FAF and its clinical application in various retinal diseases.

Acute zonal occult outer retinopathy (AZOOR) complex associated with torpedo retinopathy following COVID-19 recombinant mRNA vaccination: a case report of a rare clinical presentation.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Linkou main branch, Chang Gung Memorial Hospital, Taoyuan, Taiwan.
Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.
Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.

This report describes a patient with polypoidal choroidal vasculopathy (PCV) with fovea-involving retinal pigment epithelium (RPE) tear that showed tissue remodeling with a good visual outcome. Imaging over the patient's clinical course from 2019 was reviewed. A 74-year-old female presented with left submacular hemorrhage and a large multi-lobular pigment epithelial detachment.

Purpose: To assess the repeatability of a microperimetry methodology for quantifying visual function changes in the junctional zone of eyes with geographic atrophy (GA) in the clinical trial context.
Methods: A post hoc analysis of the OAKS phase III trial was conducted, which enrolled patients with GA secondary to age-related macular degeneration. Microperimetry using a standard 10 - 2 fovea centered grid was performed at baseline and follow-up visits.

Deep Learning to Predict the Future Growth of Geographic Atrophy from Fundus Autofluorescence.

Genentech, Inc., South San Francisco, California.
Purpose: The region of growth (ROG) of geographic atrophy (GA) throughout the macular area has an impact on visual outcomes. Here, we developed multiple deep learning models to predict the 1-year ROG of GA lesions using fundus autofluorescence (FAF) images.
Design: In this retrospective analysis, 3 types of models were developed using FAF images collected 6 months after baseline to predict the GA lesion area (segmented lesion mask) at 1.
