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...

Comparison of paediatric migraine and healthy controls using optical coherence tomography angiography

The authors present a cross-sectional study which recruited patients with paediatric migraine without aura along with age and sex-matched healthy controls. Both groups were recruited following attendance to an ophthalmology outpatient clinic. Children diagnosed with any of the following were...

Manchester Royal Eye Hospital first in UK to use ultra-wide field OCT angiography machine in patient facing setting

Manchester Royal Eye Hospital announces it is the first in the UK to utilise the ultra-wide field OCT angiography machine, the Xephilio OCT-S1 from Canon, in a patient facing setting.

Sense Medical @ 100% Ophthalmology: Widefield OCT angiography

@10:15 - 11:15 In this session we will explore the research and clinical opportunities that have become possible with the advent of wide-field optical coherence tomography angiography ( OCT-A). Tariq Aslam, Consultant ophthalmologist - Manchester Royal Eye Hospital

OCT changes in chronic optic neuropathy

The authors evaluated optical coherence tomography (OCT) angiography in 10 patients who suffered various types of chronic optic neuropathies. Glaucoma is known to cause a decrease in peripapillary perfused capillary density on OCT angiography. However, other optic neuropathies have not...

FA findings in treatment-naive premature infants

This retrospective study examined fluorescein angiography (FA) images of 162 eyes of 81 treatment-naive infants with retinal vascular immaturity and persistent avascular retina (PAR) despite exceeding postmenstrual age of 60 weeks. Disc diameter (DD), optic disc-to-fovea distance (FD), the length...

Videos - iStent Inject

Trabecular bypass surgery with iStent Inject enhances aqueous outflow from the eye , evidence of this is demonstrated through Angiographic visualization of aqueous humor outflow in studies conducted by Dr. Alex Huang M.D, Ph.D

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

Multimodal Retinal Imaging

Understanding of rapidly advancing retinal imaging techniques is important as they have changed the management of retinal conditions considerably. Interpretation of these tests is a vital skill in the armamentarium of every practising ophthalmologist. The book is directed at general...

OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

OCTA and pigment epithelium detachments

Yannuzzi et al. report on their study aiming to evaluate the ability of optical coherence tomography angiography (OCTA) to differentiate vascularised from nonvascularised pigment epithelium detachments (PEDs) using conventional imaging techniques, including fundus fluorescein angiography (FFA) and indocyanine green (ICG),...

Updated staging of LCHADD retinopathy

The authors present their proposal for an updated staging system for Long-Chain 3-Hydroxyacyl-CoA Dehydrogenase (LCHAD) deficiency retinopathy. This is a rare mitochondrial disease due to deficiency of the long chain fatty acid oxidation pathway. Forty patients who were part of...
