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 ...

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 ...

An Early Finding of Keratoconus: Increase in Corneal Densitometry

Cornea, 2018
Purpose: To investigate the corneal densitometry in subclinical keratoconus with normal elevation and pachymetric parameters. Methods: Patients with clinical keratoconus in one eye and subclinical keratoconus in the fellow eye were identified.

Corneal densitometry and topography in patients with primary congenital glaucoma

Journal Français d'Ophtalmologie, 2020
To compare corneal densitometry and topography variables in patients with primary congenital glaucoma (PCG) and healthy subjects.Cross sectional study, consecutive recruitment with gender- and age-matched control group. Forty eyes of 40 patients in each group were studied with Pentacam corneal topography.

Corneal densitometry after accelerated corneal collagen cross-linking in progressive keratoconus

International Ophthalmology, 2018
To analyze changes in corneal densitometry 3 months after accelerated corneal collagen cross-linking (CXL) measured with Scheimpflug tomography.In this study we reviewed charts and anterior segment data of patients who had undergone accelerated pulsed epithelium-off CXL (30 mW/cm2 for 4 min, 8 min total radiation time) for treatment of progressive ...
