OCT Angiography in Retinal and Macular Diseases

OCT angiography (OCT-A) is based on the concept that in a static eye, the only moving structure in the fundus of the eye is blood flowing through the vessels. This book explains how the technique allows a depth-resolved analysis and...

Fluorescein angiography and OCT in myopic CNV

Fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are the most common examinations used in the management of anti-VEGF therapy in choroidal neovascularisation (CNV). In comparison to FA, OCT provides a noninvasive evaluation of the macula. Myopic CNV are...

Wet AMD outcomes post cataract surgery

The authors present the findings of a retrospective study looking at the progression of wet age-related macular degeneration (AMD) in patients who underwent cataract surgery. They recruited a series of 111 patients of which 38 were men and 73 were...

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...

Retinopathy of prematurity

This review article describes the pathophysiology of retinopathy of prematurity (ROP). The authors start by introducing the condition and its incidence. There is extensive information on the pathophysiology mechanisms involved in the condition to include normal and pathological retinal development....

Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

Hot debates in medical retina and imaging: Perspectives from the Controversies in Ophthalmology 2020 virtual conference

Controversies in medical retina and imaging were debated during the Controversies in Ophthalmology 2020 virtual conference held during two mid-day scientific sessions on 27 and 28 March 2020. The author recounts key perspectives and presents viewpoint recommendations from the Vision...

Topcon Healthcare National OCT Conference (prior to Optix Conference)

by Laura Williams The National Optical Coherence Tomography (OCT) Conference – the industry conference organised by Topcon Healthcare – went ahead as an in-person event for the first time in three years. It was a widely welcomed return to in-person...

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...

The Ophthalmic Imaging Association holds successful first virtual conference

When the coronavirus pandemic hit, many of the things we enjoy were postponed or cancelled, including the 2020 Ophthalmic Imaging Association (OIA) conference. The Ophthalmic Imaging Association committee began focusing on 2021 but it soon became apparent a face-to-face conference...
