Comparison of the anterior ocular segment measurements using swept-source optical coherent tomography and a scanning peripheral anterior chamber depth analyzer

Abstract

Based on our results, the SS-OCT and SPAC measurements of the anterior segment were significantly correlated, but the values cannot be considered to be directly interchangeable.

A new algorithm and problems in automatic anterior eye chamber volume determining

“…Because it is easy to obtain it, there exist dedicated methods of image analysis and processing capable of performing this type of measurement fully automatically [38]. The methods proposed and implemented by tomographs' manufacturers work properly even for patients with a high degree of pathology or for large interindividual variability.…”

In Vivo Identification of the Posttrabecular Aqueous Outflow Pathway Using Swept-Source Optical Coherence Tomography

“…Due to recent advancements in hardware and software, technologies including the SS system and multiple scan averaging that were developed in posterior segment OCT have been incorporated in anterior segment OCT systems, achieving high-speed, high-quality, and high-penetration imaging. [21][22][23][24][25][26][27] In this study, en face OCT imaging, which has also been used in retinal and choroidal diseases, was applied for visualization of the vasculature, 28,29 whereas previous studies reported B-scanbased vessel image construction. 30,31 Combined with the flattening technique, the use of the en face video and its projection (vasculature map) revealed a clear blood stream that was not depicted by a sequential stack of B-scans.…”

Changes in Anterior Segment Morphology of Iris Bombe before and after Laser Peripheral Iridotomy in Patients with Uveitic Secondary Glaucoma

“…The two graders agreed on their evaluations of study parameters. The instrument software in the SS-1000 Casia instrument analyzed the following parameters: anterior chamber depth (ACD; mm), anterior chamber volume (ACV; mm 3 ), ACA (angle opening distance [AOD750; mm] and trabecular iris space area [TISA750; mm 2 ]), iris thickness (IT; mm), iris volume (IV; mm 3 ), and iris curvature (IC; mm) [11]. The AOD750 was defined as the distance from the corneal endothelium to the anterior iris surface, perpendicular to a line drawn 750  μ m anterior to the scleral spur.…”
