The effect of smoking on corneal densitometry and endothelial cell morphology
Cutaneous and Ocular Toxicology, 2021We investigated corneal endothelial morphology and corneal densitometry in smokers and compared our results with findings observed in non-smokers.This cross-sectional observational study included 100 participants (50 smokers, 50 non-smokers) aged 18-80 years in whom corneal endothelial morphology was analysed using a non-contact Tomey EM-4000 specular ...

Reasons to reconsider interpretation of densitometry for corneal transparency
Vestnik oftal'mologii, 2016To assess the effect of light scattering in the corneal epithelium on densitometric brightness of the stroma through mathematical modeling of the interaction between a light beam and the two-layer epithelium-stroma system.In order to study the scattering behavior of a plane-parallel non-coherent beam at the epithelium-stroma interface, a multi-age ...

Corneal Densitometry as a Novel Technique for Monitoring Amiodarone Therapy
Ophthalmology, 2016The clinical efficacy and toxicity of amiodarone may be determined more effectively by tissue deposition than by levels of the agent in serum. Therefore, corneal densitometry might be useful for therapeutic monitoring. The aim of the study is to evaluate Scheimpflug corneal densitometry in patients with amiodarone keratopathy (AK).Comparative case ...

Scheimpflug Corneal Densitometry Changes After the Intrastromal Corneal Ring Segment Implantation
Cornea, 2020Purpose: To investigate the changes in corneal backward scattering using Scheimpflug tomography (densitometry) 6 months after intrastromal corneal ring segments (Keraring) implant for keratoconus and to correlate with clinical results.
