Evaluation of Scheimpflug imaging parameters in blepharospasm and normal eyes. [PDF]

open access: yesBMC Ophthalmol, 2018
To investigate changes in corneal elevation, pachymetry, and keratometry in discriminating between normal and blepharospasm eyes, as measured by the Pentacam rotating Scheimpflug camera.This was a prospective, cross-sectional study. A total of 47 consecutive patients with a range of blepharospasm severity and 40 age- and sex- matched healthy subjects ...

Image Analysis of Scheimpflug Negatives

open access: yesOphthalmic Research, 2009
Evaluation of various long-term studies on changes of different lens opacities, as had been rendered possible by microdensitometric image analysis of the film blackening of Scheimpflug photographs, showed that only in a few special cases an extension of the opacification to adjacent lens layers is to be expected within the observation period of 2–3 ...

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 ...

Evaluation of Posterior Astigmatism Measured With Scheimpflug Imaging [PDF]

open access: yesCornea, 2014
Our aim was to assess the corneal power, axis, and age dependence of the anterior and posterior corneal surfaces with Scheimpflug imaging.Patients older than 10 years without a history of ocular surgery, corneal diseases, contact lens wearing, or severe dry eye were enrolled.

Diagnostic imaging techniques in patient with liquefied aftercataract imitating intraocular lens opacification

open access: yesAmerican Journal of Ophthalmology Case Reports, 2022
An 81-year-old patient was referred for an intraocular lens (IOL) exchange surgery because of a presumed IOL opacification. Using diagnostic imaging techniques such as anterior segment optical coherence tomography (OCT) and Scheimpflug imaging, we ...

Distribution of corneal densitometry in different grades of keratoconus

open access: yesIndian Journal of Ophthalmology, 2023
Purpose: To evaluate the use of Scheimpflug tomography in corneal densitometry (CD) in comparing the stages of keratoconic eyes. Methods: Keratoconic (KC) corneas (stages 1–3 classified according to the topographic parameters) were examined using the ...

Geometric model of image formation in Scheimpflug cameras [PDF]

open access: yes, 2016
We present a geometric model of image formation in Scheimpflug cameras that is most general. Scheimpflug imaging is commonly used is scientific and medical imaging either to increase the depth of field of the imager or to focus on tilted object surfaces. Existing Scheimpflug imaging models do not take into account the effect of pupil magnification (i.e.

The role of Scheimpflug imaging in the management of posterior scleritis

open access: yesEye and Brain, 2010
Posterior scleritis is a rare but sight-threatening ocular inflammatory disorder that can present in a number of different ways and sometimes silently. Diagnosis can be difficult, and usually is clinical, confirmed by B-mode ultrasonography. Patients can be at risk of angle-closure glaucoma in this condition, and traditional methods of angle assessment

One‐Year Results of Accelerated Transepithelial Corneal Cross‐Linking for Progressive Keratoconus: A Prospective Interventional Study

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Background Keratoconus is a progressive corneal ectatic disorder. Accelerated transepithelial corneal cross‐linking (ATE‐CXL) aims to halt progression while preserving the epithelium, but evidence on its 12‐month efficacy requires further evaluation.

Intraocular lens alignment from Purkinje and Scheimpflug imaging [PDF]

open access: yesClinical and Experimental Optometry, 2010
The improved designs of intraocular lenses (IOLs) implanted during cataract surgery demand understanding of the possible effects of lens misalignment on optical performance. In this review, we describe the implementation, set-up and validation of two methods to measure in vivo tilt and decentration of IOLs, one based on Purkinje imaging and the other ...
