Scheimpflug imaging for keratoconus and ectatic disease

open access: yesIndian Journal of Ophthalmology, 2013
Scheimpflug cross-sectioning anterior segment imaging offers significant advantages over traditional placido based curvature analysis and ultrasound pachymetry. The accurate measurement of both the anterior and posterior corneal surfaces and the anterior and posterior lens allows for the creation of a three-dimensional reconstruction of the anterior ...

Development of a Scheimpflug Lidar System for Atmospheric Aerosol Monitoring

open access: yesEPJ Web of Conferences, 2016
This work presents a Scheimpflug lidar system which was employed for atmospheric aerosol monitoring in southern Sweden. Atmospheric aerosol fluctuation was observed around rush-hour. The extinction coefficient over 6 km was retrieved, i.e., 0.15 km-1, by

Scheimpflug Records without Distortion – A Mythos?

open access: yesOphthalmic Research, 1999
The Scheimpflug principle was recommended as allowing distortion-free imaging; however, a detailed analysis reveals geometrical errors as well as distortions arising from absorption of light along the optical pathway. Correction formulas and factors will be presented and applied to the biometry of the eye.

Keratoconus Detection Based on a Single Scheimpflug Image

open access: yesTranslational Vision Science & Technology, 2020
To introduce a new approach for keratoconus detection based on corneal microstructure observed in vivo derived from a single Scheimpflug image.Scheimpflug single-image snapshots from 25 control subjects and 25 keratoconus eyes were analyzed; from each group, five subjects were randomly selected to provide out-of-sample data.

Postoperative Capsular Bag Distension Syndrome: Case Report of an Early Case Following Athalamia due to Vigorous Eye Rubbing. [PDF]

open access: yesCase Rep Ophthalmol Med
Introduction Capsular bag distension syndrome (CBDS) is a rare complication of phacoemulsification, characterized by fluid retention in the capsular bag leading to reduced visual acuity, a myopic shift, and a risk of pupillary block. Case Presentation We report the case of a 65‐year‐old male who developed CBDS after rubbing his eye vigorously ...

Precision of Pachymetry Measured With a Portable High-Resolution Ultrasound, a Standard Ultrasound, and Two Scheimpflug Pachymeters. [PDF]

open access: yesJ Ophthalmol
Subject To assess the precision (repeatability and reproducibility) and agreement of central corneal thickness (CCT) measurements by a high‐resolution ultrasound (E‐pach), a standard ultrasound, and two Scheimpflug pachymeters in healthy eyes. Methods Instrument diagnostic test study. A total of 100 healthy volunteers were enrolled to measure right‐eye
