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. 000125985 536__ $$9info:eu-repo/grantAgreement/EUR/MICINN/TED2021-130723A-I00 000125985 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000125985 590__ $$a2.1$$b2023 000125985 592__ $$a0.457$$b2023 000125985 591__ $$aOPTICS$$b59 / 119 = 0.496$$c2023$$dQ2$$eT2 000125985 593__ $$aAtomic and Molecular Physics, and Optics$$c2023$$dQ2 000125985 593__ $$aRadiology, Nuclear Medicine and Imaging$$c2023$$dQ2 000125985 593__ $$aInstrumentation$$c2023$$dQ2 000125985 594__ $$a2.6$$b2023 000125985 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000125985 700__ $$aBasabilbaso, Silvia 000125985 700__ $$0(orcid)0000-0002-3979-4528$$aRemon, Laura$$uUniversidad de Zaragoza 000125985 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
