TowardPi BMizar: Revolutionising Ophthalmic Imaging with Ultra High-Speed Precision
A powerful ophthalmic imaging system that establishes a new benchmark in optical coherence tomography (OCT) and OCT angiography (OCTA). Engineered with an ultra high speed 400 kHz swept source, this device delivers rapid, highly detailed scans of both the anterior...
Transsynaptic retrograde degeneration linked to homonymous visual field loss after stroke
centre, of individuals identified with homonymous visual field loss post ischaemic stroke. Exclusion criteria were bilateral ischaemia, anterior / pregeniculate visual pathway affected and other pathology with the potential to effect visual fields. The following were extracted from the medical...
Retinal ischaemia on OCTA and diabetic retinopathy grade
The authors quite rightly point out that quantification of retinal ischaemia has the potential to serve as a biomarker for diabetic retinopathy disease progression. They set out to investigate the relationship between area of ischaemia on a swept source OCTA...
Assessment of retinal capillary VD and FAZ area in CSC using OCTA
The authors aim to report a cross-sectional, case controlled study, the purpose of which was to access the retinal capillary vessel density (VD) and foveal avascular zone (FAZ) area in acute and chronic central serous chorioretinopathy (CSC) patients compared to...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...
Macular atrophy and choriocapillaris nonperfusion
This Japanese study compared the choriocapillaris (CC) nonperfusion area as measured on OCTA with areas of macular atrophy (MA) measured by fundus autofluoresence (FAF). A total of 44 eyes were assessed (31 were treated with anti-VEGF alone and 13 had...
Migraine attack: does retinal and peripapillary blood flow change?
This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...
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...
Glaucoma and capillary perfusion
Elevated IOP is important but not the sole factor responsible for retinal ganglion cell (RGC) death and optic nerve damage in glaucoma. There is increasing evidence that visual loss correlates with macular inner retinal thinning. A total of 148 eyes...
Short-term effects of atropine measured by OCTA for myopia progression
This was a prospective observation cohort study to evaluate the effect of atropine on axial length (AL), choroidal thickness and choroidal stromal volume (CSV) using swept-source OCT angiography (OCTA). The study included 26 subjects of which 25 had sufficient quality...
Clinical Applications of Optical Coherence Tomography Angiography
Clinical Applications of Optical Coherence Tomography Angiography provides an informative, up-to-date review of the numerous applications of OCTA in ophthalmology. This book highlights the ways in which this relatively recent non-invasive imaging technique has been an invaluable tool for our...
