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.

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

Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications. [PDF]

, 2017
BACKGROUND: Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity.

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 ...
