OCT-A imaging in Grave’s orbitopathy and orbital decompression
In this case series of 12 patients and 24 orbits, the authors describe the changes in the optic nerve and peripapillary blood vessel density in patients with moderate to severe Grave’s Orbitopathy (GO) undergoing orbital decompression. The patients undergoing orbital...
OCT measurements of eye muscles for Grave’s disease
The purpose of this study was to use optical coherence tomography (OCT) to assess horizontal rectus muscle thickening in patients with active and inactive Grave’s ophthalmopathy (GO) compared to healthy controls. This was a cross section observation study of rights...
Diagnostic accuracy of enhanced depth imaging OCT in children
The authors present the findings of a retrospective cross-sectional case series. Cases were identified using a treatment register having been evaluated in a set one-year period. Two ophthalmologists acted as masked image examiners for enhanced depth imaging optical coherence tomography...
Measurement considerations in OCT results with suspected glaucoma
The purpose of this study was to determine retinal nerve fibre (RNFL) thickness parameters and assess the relationship between the cup-to-disc (CD) ratio and RNFL measurements of paediatric patients who had optic nerve appearance suspicious for glaucoma based on enlarged...
Handheld OCT in children with Down’s syndrome
This article investigated the use of handheld optical coherence tomography (OCT) in children with Down’s syndrome. Fourteen children were recruited to the study with a mean age of 6 years and 10 months with 57% male. All patients were dilated....Cybersight: Using OCT as an Approach to Diagnose Glaucomatous and Other Optic Neuropathies
Clinically, the difference between glaucomatous and simple optic atrophy of other origins is not always clear. OCT with the ability to image and measure inner retinal layers in the macula and peripapillary area, with the measurement of rim atrophy, is...
Central corneal and epithelial thickness measured by Fourier domain OCT
This study examined intraobserver and interobserver reproducibility of corneal thickness (CT) and epithelial thickness (ET) measurement of Fourier domain OCT (RTVue) in 23 healthy volunteers. RTVue is capable of producing 26,000 A scans per second with depth resolution of 5µm....
OCT choroidal signs for congenital retinal pigment epithelium hypertrophy
Congenital hypertrophy of the retinal pigment epithelium (CHRPE) on ocular coherence tomography (OCT) has the characteristic sign of RPE thickening and hyper reflectivity. However, the underlying choroid characteristics remain under researched. This retrospective study utilised data from an ophthalmic oncology...
Relating metamorphopsia severity and OCT findings in advanced epiretinal membranes
The authors present the findings of a retrospective study to correlate metamorphopsia and ectopic inner foveal layers (EIFL) or ‘central bouquet’ abnormality (CBA) in patients with advanced stages of epiretinal membrane (ERM) following the new OCT‐based grading scheme as described...
Fixation target position for increased limbus measurement accuracy with AS-OCT
The authors intended to determine the optimal gaze fixation points for lateral rectus and medial rectus muscle insertions using anterior segment - optical coherence tomography (AS-OCT) compared with intraoperative measurements. They recorded 46 lateral and 36 medial rectus muscles from...
OCT biomarkers in asymmetric anti-VEGF response in bilateral diabetic macular oedema
This study aimed to identify optical coherence tomography (OCT) biomarkers for predicting response to anti-VEGF treatment in diabetic macular oedema (DMO). Bilateral DMO patients with asymmetric response to a loading dose of anti-VEGF (ranibizumab / aflibercept) treatment were retrospectively studied....
