Black Sea Journal of Health Science, 2022 The aim of this study is to compare corneal and lens density of children with Beta (β) thalassemia and healthy controls using Pentacam HR. This is a case-control and cross-sectional study. Anterior segment parameters, corneal, and lens densitometry of patients with β-thalassemia and healthy controls were evaluated with Scheimpflug corneal topography ...

A Four-Year Observation of Corneal Densitometry After Implantable Collamer Lens V4c Implantation [PDF]
Annals of Translational Medicine, 2021 To observe the changes in corneal densitometry (CD) with a Pentacam after implantable collamer lens (ICL) V4c implantation in myopia patients, and to investigate potential influencing factors.We reviewed 65 eyes of 33 patients (mean age, 29.08±5.54 years) with myopia or myopic astigmatism who underwent ICL V4c implantation.

Evaluation of Corneal Densitometry and Endothelial Layer in Soft Contact Lens Users
Optometry and Vision Science, 2021SIGNIFICANCE Soft contact lens wear may lead to physiological changes in the cornea. Corneal densitometry is a new software tool that may detect these physiological changes by monitoring their effects on corneal transparency.

Corneal Structure, Transparency, Thickness and Optical Density (Densitometry), Especially as Relevant to Contact Lens Wear—A Review [PDF]
Contact Lens and Anterior Eye, 2019 Clinical instruments using Scheimpflug image-based methods to obtain optical sectional images of the cornea have been introduced in recent years along with proposals that it should be possible to routinely and reliably measure the optical density (referred to as the densitometry) of the human cornea in situ.

A comparative study of vertebrate eye lens crystallins using isoelectric focusing and densitometry
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19931. The crystallin proteins of numerous species belonging to different classes of vertebrates have been studied. 2. Species-specific crystallin patterns are revealed which unequivocally characterize the different species. 3. A marked variability in the number and percentage of alpha-, beta- and gamma-crystallins were found in the various species. 4. The
