OCT angiography metrics in children

This prospective study aimed to quantify the vessel density of both the macular and optic nerve and foveal avascular zone (FAZ) values in 92 normal eyes of 92 children (42 boys, 50 girls) aged 13.4 ±2.65 years (seven to 18)....

OCT angiography in PAMM secondary to CRVO

Paracentral acute middle maculopathy (PAMM) is a recently described manifestation presenting with hyperreflective bands within mid retina on spectral domain optical coherence tomography (SD OCT). The current view is that these findings are markers of ischaemia of deep retinal circulation....

Fluorescein angiography and OCT in myopic CNV

Fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are the most common examinations used in the management of anti-VEGF therapy in choroidal neovascularisation (CNV). In comparison to FA, OCT provides a noninvasive evaluation of the macula. Myopic CNV are...

OCT angiography and retinal vein occlusions

In this retrospective, observational case series, the authors set out to evaluate the morphology of the superficial and deep capillary plexa of eyes that suffered a retinal vein occlusion (RVO) on OCT angiography (OCTA) and compare the findings with fluorescein...

OCT angiography findings in amblyopic eyes

In this study, optical coherence tomography angiography (OCTA) was used to detect the existence of any vascular dysfunction in superficial and deep retinal layers that accompany visual impairment in amblyopic eyes compared to fellow and control eyes. The study included...

OCT Angiography in Retinal and Macular Diseases

OCT angiography (OCT-A) is based on the concept that in a static eye, the only moving structure in the fundus of the eye is blood flowing through the vessels. This book explains how the technique allows a depth-resolved analysis and...

OCT angiography sign after whiplash

Berlin’s oedema is a rare condition following blunt ocular injury and a rare finding after whiplash injury. This case describes a 48-year-old male who suffered a seventh vertebrae fracture from a traffic accident. Two days later, decreased left eye visual...

Nerve head in healthy humans using OCT-angiography

Optical coherence tomography angiography (OCT-A) is a recent, dyeless, and noninvasive imaging technique for evaluating depth-resolved vascular status by capturing the dynamic motion of the erythrocytes. It provides the flow map of major vessels and capillary plexuses separately in different...

Atlas of Wide-Field Retinal Angiography and Imaging

Through extensive illustrations, this book, comprehensively yet concisely, covers the diagnostic speciality of wide-field retinal angiography and imaging. There are 15 chapters with contributions from 29 leading experts in this particular field who are mainly based in the USA, but...

Using optical coherence tomography angiography to detect MoyaMoya vasculopathy

Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in...

ZEISS receives FDA clearance for CLARUS 700, enabling high-resolution, ultra-widefield imaging with fluorescein angiography

ZEISS's Medical Technology Segment announced that it has received 510(K) clearance from the FDA for the CLARUS® 700, High-Definition, Ultra-Widefield Imaging system for advanced care specialists. CLARUS 700 is the first high-resolution ultra-widefield imaging with true colour and a complete range of fundus imaging modalities, including fluorescein angiography (FA).
