Overview

Randomized trial examines changes in fluorescence lifetime in geographic atrophy, indicating potential for early monitoring.

Key Points

  • The aim is to investigate changes in fluorescence lifetime in the border zone of geographic atrophy due to age-related macular degeneration.
  • Patients with geographic atrophy due to age-related macular degeneration were studied over approximately 5 years.
  • Fluorescence lifetime imaging ophthalmoscopy, fundus autofluorescence, optical coherence tomography, and color fundus photography were utilized.
  • Measurements were taken at the fovea, GA, and areas near the border zone of atrophy.
  • The geographic atrophy area increased by an average of 1.21 mm2/year.
  • Fluorescence lifetime decreased toward unaffected retina and showed significant correlation with GA growth rate (P = 0.02, r2 = 0.17).
  • The FLT gradient at the border zone was predictive of GA progression rate.
