EYE - Glaucoma
The authors describe a study using the Casia OCT which is a swept source OCT to determine the visibility of the angle structures using two imaging protocols; high density and low density. They randomly selected one eye from 30 normal...
OCT measures of lateral and medial recti
The authors assessed the agreement of the measurements of the horizontal rectus muscle insertion distance to the limbus and the muscle thickness between three different OCT devices. This was a cross section observation study of 70 eyes of 35 subjects....iScan80 OCT
The iScan80 now boasts 80,000 A-scans per second. It is a fully-integrated, compact, easy-to-use automated OCT system which includes a full suite of retina, optic nerve and anterior segment scans. Retina mapping with normative comparison Retina change analysis Ganglion Cell...iVue80 OCT
The new iVue80 OCT system is a powerful clinical tool. Performing 80,000 A-scans per second, it transforms the way you assess the retina, optic disc and cornea. Retina, glaucoma & cornea scans Change & OU analysis Ganglion cell complex thickness...

EYE - Glaucoma
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...

EYE - Vitreo-Retinal
The authors set out to evaluate an OCT-based positioning regimen for macular hole surgery. Patients were advised to maintain prone positioning until the hole was confirmed to be closed based on daily OCTs. Surgery consisted of 23-gauge phacovitrectomy with internal...
The treachery of images – making sense of OCT imaging
In 1929 Belgian surrealist Rene Magritte produced his painting La Trahison des Images. It depicted an old fashioned pipe for smoking tobacco and underneath were the words “ceci n’est pas une pipe”, this is not a pipe. You may wonder...

EYE - Neuro-ophthalmology
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...
SD-OCT detection of minimally visible retinoblastoma
This paper reports minimally visible tumour recurrence that was detectable on spectral domain OCT (SD-OCT) in a two-month old infant who had a diagnosis of bilateral familial retinoblastoma. The infant was treated with IVC for six cycles with vincristine, etoposide...
CSD-OCT detection of minimally visible retinoblastoma
This paper reports minimally visible tumour recurrence that was detectable on spectral domain OCT (SD-OCT) in a two-month-old infant who had a diagnosis of bilateral familial retinoblastoma. The infant was treated with IVC for six cycles with vincristine, etoposide and...A new observation point: updating the nomenclature and classification with OCT
The evolution of ophthalmic imaging technologies has been particularly rapid over the last few years. The author provides an update of the current terms for common signs and pathologies observed using optical coherence tomography. My experience as an ophthalmic technician,...

EYE - Vitreo-Retinal
The purpose of this study was to determine whether it is feasible to obtain good-quality images with anterior segment OCT (AS-OCT) in patients with episcleral or scleral inflammation located anterior to the equator, and whether this technique is able to...
