Essentials of OCT in Ocular Disease
Sir Isaac Newton was the first to establish the technique of low coherence white light interferometry. Following on from this, the principle of laser interferometry as an imaging modality for retina was applied by David Huang and his associates in...
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...
Comparison of bleb grading and IOPs
The purpose of this study was to compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system (Moorfields) and both with intraocular pressure (IOP) levels following trabeculectomy surgery. The authors developed a...
Reproducible OCT RNFL map in unilateral glaucoma
The aim of the study was to compare the reproducibility of the optical coherence tomography retinal nerve fibre layer (OCT RNFL) thickness map between glaucomatous and fellow normal eyes of unilateral glaucoma patients. The authors carried out a prospective case...
Time domain vs. spectral domain in the measurement of the optic nerve head
The authors describe a prospective study of 40 participants (20 healthy and 20 with glaucoma) enrolled to compare the measurements of the optic nerve head (ONH) parameters given by time domain (TD) and spectral domain (SD) optical coherence tomography (OCT)....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...
Handbook of Pediatric Retinal OCT and the Eye-Brain Connection
Paediatric optical coherence tomography (OCT) imaging of the eye remains an evolving technology to date. This handbook delves into this challenging area successfully and gives a comprehensive and detailed input into paediatric OCT pertaining to the retina and the optic...
OCT positioning regimen in macular hole surgery
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...Sense Medical and Canon: Getting ready for the OCT Pathway in Diabetic Eye Screening Surveillance Pathway webinar
Are you ready for the OCT pathway in DESP? OCT is set to be integrated into the English National Diabetic Eye Screening Surveillance Pathway, significantly enhancing the management of patients with mild diabetic maculopathy. This advancement allows patients to remain within a surveillance pathway overseen by retinal screening rather than being immediately referred to the Hospital Eye Service (HES). The webinar will be hosted by Professor Tunde Peto and Mrs Samantha Mann and will discuss the new OCT pathway, how OCT will change diabetic screening, how to interpret OCT images and how programmes can get ready for the change. Starts at 6pm UK time for 90 minutes
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...
