BACKGROUND AND OBJECTIVE: To correlate subfoveal choriocapillaris (CC) flow density with age using spectral-domain optical coherence tomography angiography (SD-OCTA). PATIENTS AND METHODS: One hundred eighty-three eyes of 94 subjects (66 female, 28 male) were enrolled. Included were healthy subjects between the ages of 21 and 82 years without any history of vitreoretinal disease. Measurements were obtained with software from the OCT device. Significance was defined as a P value of less than .05. RESULTS: The mean age was 43.43 years ± 17.63 years. Correlation between decreasing CC flow density and increasing age was significant (P < .001), with a mean yearly flow decrease of 0.026%. Subfoveal choroidal thickness decreased with advancing age; however, this did not reach a level of significance (P = .069). CONCLUSION: There is a significantly negative correlation between CC flow density and advancing age in healthy subjects, analyzing direct extracted in-built software values from a commercial SD-OCTA device.
