PURPOSE Comparing diagnostic accuracy of biomicroscope techniques (van Herick and Smith's tests, evaluating limbal and central anterior chamber depth, respectively) and advanced imaging (Visante OCT and Pentacam) for detection of gonioscopically narrow anterior chamber angles (ACAs). METHODS A total of 78 subjects with narrow or open ACAs underwent four index tests, performed on both eyes by ...

Purpose: To report a case of posterior keratoconus with atypical ocular findings Case report: An 8-year-old boy was referred to our clinic with the chief complaint of blurred vision in his right eye. The patient had no history prior ocular surgery of trauma. Her family history was also unremarkable. Comprehensive ocular examination was performed. Results: The patient's best spectacle corrected ...

The aim of this study was to compare the central and peripheral pachymetric measurements determined with Sirius system and Visante OCT and evaluate the agreement between them at different stages of keratoconus. Measurements were not significantly different in all patients and subgroups and showed high correlation for the corneal thicknesses of the entire cornea in different stages of keratoconus.

PURPOSE To investigate the repeatability and reproducibility of the Visante Omni topography in obtaining topography measurements of rabbit corneas and to develop a post-surgical model of corneal ectasia. METHODS Eight rabbits were used to study the repeatability and reproducibility by assessing the intra- and interobserver bias and limits of agreement. Another nine rabbits underwent different...

6.3 μm and 6.5 μm, respectively. We agree that there are limitations to all techniques that measure corneal thickness including the Visante OCT. However, we do not agree with the assertion that the resolution of the system is 12 μm and that standard deviations reported less than this are not valid. Jason E. Stahl, MD Daniel S.

PURPOSE To identify the clinical and anatomic characteristics of filtering blebs after glaucoma surgery with a new biodegradable collagen implant, Ologen, using ultrasound biomicroscopy (UBM) and Visante anterior segment optical coherence tomography (OCT). METHODS The authors conducted a prospective interventional case series in 15 eyes with openangleglaucoma. The authors performed limbal-bas...

PURPOSE To determine the repeatability and reproducibility of central and peripheral corneal pachymetry mapping with anterior segment-optical coherence tomography (AS-OCT). METHODS An observational cross-sectional study involving two groups: 27 healthy eyes and 20 eyes with keratoconus. Each subject underwent scanning sessions with AS-OCT to determine intraobserver repeatability, interobserve...
