Simultaneous optical coherence tomography and Scheimpflug imaging using the same incident light [PDF]
, 2020 For any single anterior chamber cross-sectional (tomographic) imaging method, there is a practical compromise between image size and image resolution. In order to obtain large field-of-view cross-sectional images of the whole anterior chamber and high ...

Forme Fruste Keratoconus Imaging and Validation via Novel Multi-Spot Reflection Topography
Case Reports in Ophthalmology, 2013 Background/Aims: This case report aims to evaluate safety, efficacy and applicability of anterior surface imaging in a patient with forme fruste keratoconus (FFKC) based on a novel multi-spot, multicolor light-emitting-diode (LED) tear film-reflection ...

Image Analysis of Scheimpflug Negatives
Ophthalmic 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 ...

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.

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

American 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
Indian 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 ...

The role of Scheimpflug imaging in the management of posterior scleritis
Eye 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
