Titel | OCT Angiography reveals a non-flow area enlargement in the choriocapillaris with increasing age |
Doel | To evaluate the relationship between age and both non-flow area and flow signal in the choriocapillaris of the macular region, as measured using optical coherence tomography angiography (OCTA). |
Methodes | 87 eyes of 87 healthy volunteers were examined using a high-speed and high-resolution spectral-domain OCT XR Avanti system with a split-spectrum amplitude de-correlation angiography algorithm. Choriocapillaris images were analysed to determine the choriocapillaris decorrelation index (CCDI), flow voids greater than 10,000 µm2 (FV10000) and signal voids greater than 40,000 µm2 (FV40000). |
Resultaten | The mean patient age was 30.55 ± 14.59 years. Mean CCDI was 116.40 ± 5.64, mean FV10000 65.85 ± 7.75 and mean FV40000 36.87 ± 15.04. Correlations between age and respectively CCDI, FV10000 and FV40000 showed a moderate but significant correlation (r = -0.3545, p = 0.0008;r = 0.3626, p = 0.0006; r =0.3897, p = 0.0002). |
Conclusie | Our results suggest an increase in non-flow areas with increasing age, which could explain the decrease in overall flow signal. |
