Corneal Densitometry for Early and Long-Term Evaluation of Surgical Outcomes After Phototherapeutic Keratectomy for Granular, Macular, and Lattice Corneal Dystrophy.

Cornea
PURPOSE To evaluate early and long-term outcomes of phototherapeutic keratectomy (PTK) in granular (GCD), macular (MCD), and lattice corneal dystrophy (LCD) using corneal densitometry as an objective marker for surgical efficacy.

Changes in corneal thickness, corneal volume, and densitometry after long-term orthokeratology wear

Contact Lens and Anterior Eye, 2023
To investigate changes in the corneal volume, corneal densitometry and pachymetry of young myopes wearing over-night orthokeratology (OK) contact lenses.The medical records of 28 right eyes of young myopes wearing OK between 2013 and 2018 were reviewed retrospectively.

Corneal densitometry and its correlation with age, pachymetry, corneal curvature, and refraction

International Ophthalmology, 2016
To determine normative corneal densitometry values in relation to age, sex, refractive error, corneal thickness, and keratometry, measured using the Oculus Pentacam system.Three hundred and thirty-eight healthy subjects (185 men; 153 women) with no corneal disease underwent an exhaustive ocular examination.

Association between corneal densitometry at initial presentation and future progression across age groups in keratoconus

Ophthalmic & physiological optics
This study investigated corneal densitometry values at presentation, acquired via Scheimpflug imaging, in eyes with and without documented progression. The aim was to determine whether corneal densitometry values at presentation were associated with the ...

Reasons to reconsider interpretation of densitometry for corneal transparency

Vestnik oftal'mologii, 2016
To assess the effect of light scattering in the corneal epithelium on densitometric brightness of the stroma through mathematical modeling of the interaction between a light beam and the two-layer epithelium-stroma system.In order to study the scattering behavior of a plane-parallel non-coherent beam at the epithelium-stroma interface, a multi-age ...
