2022年10月29日 · 本研究表明基于前节oct的itc分析能够精确鉴别存在解剖性房角关闭的眼睛。itc范围与pac/pacg的患病几率有关，itc的360°评估可为原发性闭角型青光眼的风险评估提供重要参考。

2022年12月11日 · 全自动虹膜和小梁网接触分析软件（ITC），对房角开放距离 (AOD)、小梁虹膜夹角 (TIA)、房角隐窝面积（ARA）、小梁虹膜空间面积TISA）的测量以及全周分布图。 前房深度ACD、巩膜突间距ACW、晶状体拱高（LV）、房角隐窝宽度（ATA）测量巩膜成像，巩膜高度测量. 上直肌成像，上直肉附着点到SS距离手动测量.

2017年11月30日 · AS-OCT is a high-resolution optically based imaging system that uses low-coherence interferometry to provide cross-sectional images of ocular tissues and has evolved from 1310-nm infrared light source time-domain (Slit Lamp Optical Coherence Tomography (SL-OCT); Heidelberg Engineering, Heidelberg, Germany and Visante, Carl Zeiss Meditec, Dublin ...

2022年4月5日 · To investigate the extent of iris trabecular contact (ITC) measured by anterior segment OCT (AS-OCT) and its association with primary angle-closure (PAC) and PAC glaucoma (PACG) in eyes with gonioscopic angle-closure and to determine the diagnostic performance of ITC for detection of gonioscopic angle-closure.

Optical coherence tomography (OCT), a noninvasive imaging modality that uses low-coherence light to obtain a high-resolution cross-section of biological structures, has evolved dramatically over the years. The Swept-source OCT (SS-OCT) makes use of a single detector with a rapidly tunable laser as a light source.

2023年4月26日 · 360度眼前段显示，能更充分量化虹膜-小梁网接触（ITC）和周边虹膜粘连（PAS）水平，增加对房角的评估手段。 后段SS-OCT和SS-OCTA除了极大的丰富了对各种眼底血管性疾病的理解外，还提高了医务工作者对玻璃体及脉络膜结构的认知。 其中对脉络膜毛细血管的观察和测量，有望阐释一些黄斑性疾病的发病机制。 文章图表. 图1：24 mm SS-OCT B-Scan清晰地显示了前段的结构，包括角膜（a）、结膜（b）、巩膜（c）、虹膜（d）、前房角（e） …

2023年5月2日 · After ICL implantation, the anterior chamber depth (ACD) becomes shallower, and the ACA becomes narrower, increasing the risk of peripheral anterior synechia. SS-OCT parameters, including the ITC index, may characterise the extent of angle-closure and other biometric parameters that reflect the mechanical obstruction of the aqueous outflow pathway.

The aim of this study was to compare AS-SS-OCT with UBM for the evaluation of iridotrabecular contact (ITC), which consists of both peripheral anterior synechia (PAS) and appositional (functional) angle closure, in narrow angle eyes.

To evaluate the prevalence and range of iridotrabecular contact (ITC) in eyes with a shallow peripheral anterior chamber (AC) by using anterior segment swept-source optical coherence tomography (AS-SS-OCT) and to compare the results with those obtained with ultrasound biomicroscopy (UBM) and gonioscopy. Methods.:

Purpose: To investigate the association between the quantitative assessment of iridotrabecular contact (ITC), measured by swept-source anterior segment optical coherence tomography (SS AS-OCT), and intraocular pressure (IOP) control after phacoemulsification in patients with primary angle closure disease (PACD).
