Corneal densitometry and associated factors in an elderly population
Clinical and Experimental Optometry, 2023Knowing normative corneal optical density (COD) values is important for identifying pathologic corneal changes.The aim of this work is to determine the distribution and associated factors of COD in the elderly population.This report is a part of a cross-sectional population-based study conducted on the elderly population (≥60 years) of Tehran, Iran ...

Corneal densitometry and its correlation with age, pachymetry, corneal curvature, and refraction
International Ophthalmology, 2016To determine normative corneal densitometry values in relation to age, sex, refractive error, corneal thickness, and keratometry, measured using the Oculus Pentacam system.Three hundred and thirty-eight healthy subjects (185 men; 153 women) with no corneal disease underwent an exhaustive ocular examination.

Corneal densitometry: A new evaluation indicator for corneal diseases
Survey of OphthalmologyCorneal densitometry (CD) uses the biological properties of the cornea to visualize the morphology of the cornea and determine the degree of corneal transparency. At present, it is an emerging metric that has shown promise in various clinical diagnosis and evaluation of eye diseases and surgeries.

Corneal densitometry evaluation in archipelago keratitis
International Ophthalmology, 2013To report a case of archipelago keratitis and its improvement as evaluated by corneal densitometry. A review of the patient's record and relevant literature. A 57-year-old man presented with blurred vision associated with photophobia and halos around lights. Slit-lamp examination revealed multiple confluent, nummular subepithelial infiltrates.

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 ...

The effect of corneal infiltrates on densitometry and higher‐order aberrations
Australasian journal of optometry, The, 2019This study aimed to measure the effects of persistent corneal subepithelial infiltrates associated with epidemic keratoconjunctivitis on corneal densitometry and total corneal higher order aberrations (HOAs), and to compare these measurements with the data obtained from their fellow unaffected healthy eyes.This prospective cross-sectional study ...

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 ...
