Corneal and lens densitometry evaluation with Pentacam HR in children and adolescents with beta thalassemia major: a case–control study

Egyptian Pediatric Association Gazette
Background Beta thalassemia major is an inherited blood disorder due to a mutation of the β globin chain gene. Ocular complications have increasingly been reported in β-thalassemia patients with a negative influence on the health related quality of life.

Corneal stromal changes following simple limbal epithelial transplantation on Scheimpflug densitometry: Early results

Indian Journal of Ophthalmology
Context: Chemical injury to eyes causes limbal stem cell deficiency (LSCD), which leads to conjunctival epithelium and underlying stromal changes. Simple limbal epithelial transplant helps to restore corneal epithelium and corneal stromal clarity.

Segmentation of the fibrillar layer in advanced fuchs endothelial corneal dystrophy: Inter‐oberserver‐reliability and intra‐observer‐repeatability analysis of corneal densitometry images

Acta ophthalmologica
Aims: Our previous studies state that a central subendothelial collagen‐rich fibrillar layer (FL) is present in about 80% of advanced Fuchs endothelial corneal dystrophy (FECD) corneas which correlates with decreased corneal endothelial cell density and ...

Normative Values for Corneal Densitometry Analysis by Scheimpflug Optical Assessment

Investigative Opthalmology & Visual Science, 2014
To describe the normative data for corneal Scheimpflug densitometry based on a cohort of normal participants.A total of 445 healthy participants were recruited for assessment (794 eyes). Left and right eyes were considered separately. All participants were assessed using the corneal densitometry analysis add-on to the standard software of the Oculus ...
