Corneal Densitometry in Keratoconus

Cornea, 2014
The aim of this study was to compare corneal densitometry measured by Scheimpflug tomography in normal and keratoconic eyes and to assess the differences in densitometry values among the stages of keratoconus.Keratoconic and normal corneas were examined using the Pentacam. Corneal densitometry was measured over a 12-mm diameter area, divided by annular

Corneal densitometry evaluation in archipelago keratitis

International Ophthalmology, 2013
To report a case of archipelago keratitis and its improvement as evaluated by corneal densitometry. A review of the patient's record and relevant literature. A 57-year-old man presented with blurred vision associated with photophobia and halos around lights. Slit-lamp examination revealed multiple confluent, nummular subepithelial infiltrates.

Corneal Densitometry

Cornea, 2016
To assess the repeatability of densitometry, a measure of corneal haze, in the control (group I), keratoconic (group II), and postcollagen cross-linking (CXL, group III) eyes as measured on Scheimpflug imaging.Densitometry values for 160 eyes of 160 patients (50 eyes of 50 patients in group I, 50 eyes of 50 patients in group II, and 60 eyes of 60 ...

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 ...
