Corneal Densitometry as an Indicator of Corneal Health

Ophthalmology, 2012
To establish prospectively the normal values of corneal density of healthy subjects using the Pentacam Scheimpflug system (Oculus, Inc., Wetzlar, Germany) and to investigate alteration in corneal density during active and healed stages of bacterial keratitis.Prospective, comparative case series.Sixty-four eyes of 40 healthy controls and 36 eyes of 35 ...

Corneal densitometry in Chinese adults with healthy corneas: associations with sex, age, ocular metrics, and optical characteristics. [PDF]

BMC Ophthalmol
Background Standardized corneal densitometry (CD) values in large samples of healthy Chinese individuals are scarce. Therefore, we aimed to determine the standard CD values using a Scheimpflug camera in healthy corneas, investigate the correlations of ...

Corneal densitometry changes after femtosecond laser-assisted intracorneal ring segments implantation in keratoconus. [PDF]

Med Hypothesis Discov Innov Ophthalmol
Background: Intrastromal corneal ring segments are commonly implanted in the corneas of eyes with mild-to-moderate keratoconus; however, changes in corneal densitometry (CD) after implantation are a matter of debate in the current literature.
