OCTA use in CNV associated with CSR
The aim of this study was to assess the rate of choroidal neovascularisation (CNV) in chronic central serous chorioretinopathy (CSR) patients with flat irregular pigment epithelial detachments (PEDs) by optical coherence tomography angiography (OCTA). Data of all consecutive patients with...
Comparison of corneal deformation parameters in keratoconic and normal eyes
This study set out to compare biomechanical properties between normal and keratoconic eyes. It was a retrospective study evaluating 89 eyes (47 normal, 42 keratoconic) and a validation arm of 72 eyes (33 normal, 39 keratoconic) using a high speed...Optegra announces programme of engaging CPD events for healthcare community
Optegra continues to strengthen its commitment to clinical excellence and community partnership by announcing a series of Continuing Professional Development (CPD) events throughout 2026, open to any health care professionals in optometry. Taking place across a range of dates and...
Effect of long-term scleral contact lenses on corneal topography, tear film and impression cytology in keratoconus
This study of 16 keratoconus patients aimed to investigate the impact of long-term scleral contact lens (ScCL) wear on corneal curvature, corneal thickness, tear film function and ocular surface in patients with keratoconus. Corneal topography, tear osmolarity test, Schirmer 1...
Hyper reflective foci (HRF) on OCT in diabetic retinopathy
This study investigated the presence of hyper reflective foci (HRF) in asymptomatic patients affected by type 1 or type 2 diabetes, separately, without clinically significant diabetic macular oedema and visual impairment. In total 71 eyes with non-proliferative diabetic retinopathy were...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...
Effects of idiopathic intracranial hypertension on the optic nerves
The authors review the latest evidence regarding how the optic nerves are affected by idiopathic intracranial hypertension (IIH), possible pathophysiology and methods of assessment. IIH is described as a clinical syndrome of raised intracranial pressure of unknown aetiology. A systematic...What’s next in retinal imaging? Faster, deeper and full-on
Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...Best way to detect glaucoma progression: by reflecting on the past 25 years
Glaucoma – a condition of optic neuropathy leading to progressive visual field loss often associated with raised intraocular pressure. It is fair to say that our definition for this condition has remained unchanged over the last 25 years and the...
Macular atrophy and choriocapillaris nonperfusion
This Japanese study compared the choriocapillaris (CC) nonperfusion area as measured on OCTA with areas of macular atrophy (MA) measured by fundus autofluoresence (FAF). A total of 44 eyes were assessed (31 were treated with anti-VEGF alone and 13 had...
OCTA to measure surgical haemodynamic changes
This study used the optical coherence tomography angiography (OCTA) technique to evaluate possible haemodynamic changes after horizontal rectus muscle surgery in 32 eyes of 16 patients; nine male, seven female. Recession / resection surgery was undertaken for two horizontal rectus...
