Anterior segment imaging: a photographer’s view
My name is Rosalyn Painter and I work within the vision science and ophthalmic imaging team at Bristol Eye Hospital, where we cover all aspects of imaging within the hospital, including fluorescein angiograms, fundus photography, optical coherence tomography (OCT), slit-lamp...
The Retinal Atlas (2nd Edition)
Those readers familiar with the first edition of The Retinal Atlas will appreciate the comprehensive nature of this publication, and this latest version incorporates retinal images generated by recently developed imaging technology. As the title suggests, this hardcover version is...
OCT in proliferative diabetic retinopathy
This report set out to describe the anatomical relationships between retinal neovascular complexes (NVC), the posterior vitreous, and the vitreoretinal interface in patients with proliferative diabetic retinopathy using spectral domain OCT. The following was recorded for each NVC 1) posterior...Advances in the understanding, diagnostic and treatment of keratoconus
*Joint first authors Keratoconus is a bilateral and asymmetric eye condition in which the cornea’s structure is affected and thinned, causing a cone-shaped bulge to develop. This results in progressive loss of vision and impairs the ability of the eye...
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...Mainline Instruments - Pentacam Educational Day
Mainline Instruments - Pentacam® Educational DayA comparison of light sources in retinal imaging
Before starting to talk about the light sources present in retinal imaging, it is necessary to start from the base: the light. Light is an electromagnetic wave whose smallest part is the photon (or quantum of light). A high frequency...
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...
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....
OCTA in angioid streaks
This paper reports on the optical coherence tomography angiography (OCTA) features of choroidal neovascularisation (CNV) secondary to angioid streaks and the ability to predict CNV activity. A total of 38 eyes of 19 patients were included in the study. Thirty...
