Subtle changes in the outer retinal and choroidal structures in individuals at elevated risk for advancing to age-related macular degeneration
To explore changes in the microstructure and blood supply of the outer retina in eyes at high risk for age-related macular degeneration (AMD).
Key Findings:
SCP and DCP densities were significantly decreased in Group 2 compared to controls, indicating compromised vascular health.
CVI was significantly decreased in superior and temporal regions in Group 2 compared to controls, suggesting altered blood supply.
Outer retinal thickness in Group 2 was significantly decreased in central, superior, and temporal regions compared to controls and Group 1, highlighting structural changes.
Total retina and choroid thickness were significantly decreased in most regions in Group 2 compared to controls, indicating overall retinal health deterioration.
Outer retinal thickness was significantly correlated to choroidal thickness in AMD patients, suggesting a relationship between these structures.
Interpretation:
Significant thinning of outer retina and choroid in dry AMD patients suggests potential biomarkers for early AMD progression, which could inform treatment strategies.
Limitations:
Small sample size may limit generalizability of findings to the broader population.
Retrospective design may introduce selection bias, affecting the reliability of the results.
Conclusion:
SS-OCTA may be useful for evaluating microstructural and blood supply disorders in the outer retinal layers, aiding in the early identification of AMD progression and potentially guiding clinical interventions.
