Evaluation of Corneal Epithelial Thickness and Dry Eye Disease Tests in Thalassemic Adolescents.

Thalassemic adolescents had thinner CET with higher thickness' variability, shorter TBUT and more marked OSS‎ than controls. Correlation of higher serum ferritin and hepatic iron overload with irregular epithelial thinning and more affected dry eye tests results supports our hypothesis that high tissue iron levels could play a pivotal role in DED pathogenesis in thalassemic patients.
