Could Corneal Densitometry be a Progression Criterion for Subclinical Keratoconus? [PDF]

Beyoglu Eye J, 2023
The objective of this study is to investigate the changes in topometry, tomography, and corneal densitometry in subclinical keratoconus (SK) at the 6-month interval.The clinical keratoconus and SK groups included 25 eyes; the control group included 22 eyes from 22 patients. Corneal topographic, tomographic, topometric, and densitometric values obtained

The Effect of ChromaGen Contact Lenses on Corneal Clarity: A Corneal Densitometry. [PDF]

Beyoglu Eye J, 2022
The purpose of this study is to investigate the effect of ChromaGen contact lens (CCL) on corneal clarity, expressed through the measurement of corneal densitometry (CD) values.This study included 22 eyes of 22 patients with congenital red-green color vision deficiency who were admitted to our clinic for the CCL trial. After a detailed ophthalmological

The intra- and inter-day repeatability of corneal densitometry measurements in subjects with keratoconus and in healthy controls [PDF]

Scientific Reports, 2023
The healthy cornea is transparent, however, disease can affect its structure, rendering it more or less opaque. The ability to assess the clarity of the cornea objectively could thus be of considerable interest for keratoconus patients. It has previously

Influence of iris color on corneal densitometry. [PDF]

J Optom
To determine whether iris pigmentation introduces a measurable bias in corneal densitometry (CD) values obtained via Scheimpflug imaging, and to develop an objective metric for iris color quantification.This observational study included 91 eyes from 47 healthy adults.
