Near-Infrared Fluorescence Lifetime Imaging Microscopy Reveals Loss of RPE Cell Body Polarity in Age-Related Macular Degeneration

Key Points

To investigate the loss of RPE cell body polarity as a potential early indicator of age-related macular degeneration.
Utilized near-infrared fluorescence lifetime imaging microscopy (FLIM) at 780 nm.
Analyzed NIR-autofluorescence lifetimes in RPE cells.
Evaluated changes associated with metabolic and intracellular organization.
Detected a significant loss of RPE cell body polarity in AMD samples.
Identified disruptions in NIR-autofluorescence lifetimes correlating with RPE alterations.
Proposed FLIM as a promising method for early biomarker identification.

Abstract

At 780 nm, FLIM detects a loss of RPE cell polarity that likely reflects intracellular reorganization and metabolic change. Disruption in NIR-autofluorescence lifetimes may provide an early biomarker for pathological RPE alterations in AMD.
