Optical coherence tomography (OCT) provides non-contact, rapid in vivo imaging of ocular
structures, and has become a key part of evaluating the anterior segment of the eye. Over …

Keratoconus (KC) is the most common cornea ectatic disorder. It is characterized by a cone‐
shaped thin cornea leading to myopia, irregular astigmatism, and vision impairment. It …

Keratoconus is the most common primary ectasia. It usually occurs in the second decade of
life and affects both genders and all ethnicities. The estimated prevalence in the general …

PURPOSE: To describe pachymetric progression indices (PPI) of the Pentacam HR (Oculus
Optikgeräte GmbH) and the concept of relational thickness, and to test their accuracy for …

Optical coherence tomography (OCT) imaging has become widespread in ophthalmology
over the past 15 years, because of its ability to visualize ocular structures at high resolution …

Corneal tomography and Scheimpflug imaging are frequently used to analyze the corneal
surface, especially in the field of cataract and refractive surgery. The Pentacam system is …

Recent advances in the diagnosis and treatment of ectatic corneal disease have mandated
a more modern staging system. The new Belin ABCD keratoconus staging system …

Purpose To screen for subclinical keratoconus by analyzing corneal, epithelial, and stromal
thickness map patterns with Fourier-domain optical coherence tomography (OCT). Setting …

PURPOSE: To assess corneal microarchitecture and regional epithelial thickness profile in
eyes with keratoconus, postoperative corneal ectasia (ectasia), and normal unoperated eyes …

Newer treatment modalities such as corneal cross-linking have increased the need to
identify ectatic disease at an earlier stage than previously required. Imaging systems limited …
