Evaluation of Transparency and Barrier Function of the Cornea by Scheimpflug Images

Ophthalmic Research, 2009
Two new methods of corneal analysis with Scheimpflug images will be introduced in this paper. The first study was to document the light scattering of the cornea itself using a newly modified Scheimpflug camera with higher magnification. Details of the slit images of the cornea could be evaluated more precisely than those of images taken with an ...

Central and peripheral corneal thickness measured with optical coherence tomography, Scheimpflug imaging, and ultrasound pachymetry in normal, keratoconus-suspect, and post-laser in situ keratomileusis eyes

, 2009
PURPOSE: To compare central (CCT) and peripheral corneal thickness (PCT) using Scheimpflug imaging (Pentacam), high-speed optical coherence tomography (Visante OCT), and ultrasound (US) pachymetry (Sonogage Corneo-Gage Plus) in normal, keratoconus ...

Does HIV accelerate the aging process? An assessment of clinical, ophthalmic and serum parameters in HIV-infected individuals in South Africa [PDF]

HIV-infected individuals are at increased risk of age-related non-AIDS morbidity and mortality compared with HIV-uninfected persons. It is speculated that HIV-infected individuals may not only be aging chronologically, but also undergoing accelerated ...

Evaluation of parameters for early detection of pediatric keratoconus

BMC Ophthalmology
Background Keratoconus in children is often more severe and rapidly progressive compared to adults. While Scheimpflug imaging (Pentacam) improves screening, there are no established pediatric guidelines.

Atmospheric aerosol monitoring by an elastic Scheimpflug lidar system

, 2015
This work demonstrates a new approach - Scheimpflug lidar for atmospheric aerosol monitoring. The atmospheric backscattering echo of a high-power continuous-wave laser diode is received by a Newtonian telescope and recorded by a tilted imaging sensor ...

Effect of Nd: YAG Laser Capsulotomy on Anterior Segment Eye Parameters using Shiempflug Imaging [PDF]

Al-Azhar International Medical Journal
Background: Posterior capsule opacification (PCO) is a common complication after cataract surgery, impairing visual acuity. Nd: YAG laser capsulotomy is the standard management, but its potential impact on anterior segment parameters and refraction ...

Differences between Scheimpflug and optical coherence tomography in determining safety distances in eyes with an iris-fixating phakic intraocular lens

, 2020
Purpose To investigate the agreement and reliability of anterior segment optical coherence tomography (AS-OCT) and Scheimpflug imaging in measuring the distance from the anterior edge of an iris-fixated phakic intraocular lens (IF-pIOL) to the corneal ...
