A total of 83 healthy participants aged 39.02 ± 18.34 years (range 9–81 years) were screened using a Ziemer Galilei G2. Images were analysed using the DDA, and two parameters, α (corneal transparency) and β (corneal homogeneity), were estimated. A two-way ANOVA analysis was performed to investigate whether α and β are influenced by age, corneal región (four concentric areas were considered), and their interaction. The parameters α and β statistically change with age and corneal region. A statistically significant interaction effect of 13% (α) and 11% (β) exists between age and corneal region. However, the corneal region plays a more significant role than aging in corneal densitometry; 31% (α) and 51% (β) of the variance can be attributed to the corneal region, while 28% (α) and 5% (β) can be attributed solely to aging. Corneal densitometry can be objectively assessed from Galilei G2 images using the DDA method. The corneal region plays a more significant role than aging in corneal densitometry. Consequently, general results on corneal densitometry and aging should be taken cautiously. info:eu-repo/grantAgreement/EUR/MICINN/TED2021-130723A-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.1 2023 OPTICS 59 / 119 = 0.496 2023 Q2 T2 0.457 2023 Atomic and Molecular Physics, and Optics 2023 Q2 Radiology, Nuclear Medicine and Imaging 2023 Q2 Instrumentation 2023 Q2 2.6 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Basabilbaso, Silvia Remon, Laura Universidad de Zaragoza (orcid)0000-0002-3979-4528 2002 385 Universidad de Zaragoza Dpto.
