Scheimpflug imaging in anterior megalophthalmos

Indian Journal of Ophthalmology, 2013
We report an anterior megalophthalmos case with decreased corneal thickness and show the findings using Scheimpflug imaging. A 25-year-old male was diagnosed with anterior megalophthalmos. In both eyes, enlarged corneal length was measured. Beside a comparatively good visual acuity, a thin but clear cornea, a fairly deep anterior chamber, and central ...

Intraocular lens alignment from Purkinje and Scheimpflug imaging [PDF]

Clinical 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 ...

Incidence and Prevalence of Keratoconus Based on Scheimpflug Imaging

Ophthalmology, 2023
The prevalence of keratoconus (Belin/Ambrόsio Enhanced Ectasia Display Score ≥2.6 on Scheimpflug imaging) in a longitudinal, community cohort study from Western Australia was 3.4% (n=26/755). Keratoconus incidence over an 8-year period was 2.2% (n=15/669).

Keratoconus Detection Based on a Single Scheimpflug Image

Translational 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.

Evaluation of Posterior Astigmatism Measured With Scheimpflug Imaging [PDF]

Cornea, 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.

Scheimpflug imaging of pediatric posterior capsule rupture

Indian Journal of Ophthalmology, 2009
We report a case of an 11-year-old boy who presented two days after blunt trauma to the left eye with a slingshot. On examination his best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/400 in the left eye. Slit-lamp examination of the left eye revealed a Vossius ring, traumatic cataract, traumatic posterior capsule tear (PCT).

Scheimpflug imaging for keratoconus and ectatic disease

Indian 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 ...

Glaucoma anterior chamber morphometry based on optical Scheimpflug images [PDF]

Arquivos Brasileiros de Oftalmologia, 2010
To compare the performance of gonioscopy and noncontact morphometry with anterior chamber tomography (High Resolution Pentacam - HR) using optical Scheimpflug images in the evaluation of the anterior chamber angle (ACA).Transversal study. 112 eyes from 74 subjects evaluated at the Glaucoma Department, Fluminense Federal University, underwent gonioscopy

Integrated Line-Field Optical Coherence Tomography and Scheimpflug Imaging for Corneal Imaging

Optics and Lasers in Engineering, 2023
Previously we demonstrated a combined scanning-point optical coherence tomography (OCT) and Scheimpflug Imaging (SI) system, to provide cross-section images of the corneal layers and the whole anterior segment of the eye simultaneously. However, to fully realise the benefits of this dual imaging modality concept towards clinical practice, it is ...
