History An Afro-Caribbean woman, aged 30, with “scleral tattooing” for cosmetic reasons (subconjunctival dye injection), presented with bilateral upper and lower eyelid oedema for one week, and she also had restricted eye movement and blurry vision in her right eye....DRI OCT Triton
SS OCT & OCTA 1050nm wavelength, 100,000 A Scans/sec Widefield OCT (21mm B-scans, 21mm x21mm OCTA) Smart Denoise for enhanced scan quality Advanced anterior imaging: 9mm Radial Scan (epithelial/ stromal mapping, corneal thickness), 16mm Line Scan (glaucoma metrics) Multimodal Imaging:...OCULUS Pentacam® OCT
The OCULUS Pentacam® Cornea OCT offers 360° 3D imaging by combining Scheimpflug and Cornea OCT technologies. It delivers consistent 1.9μm resolution across the entire cornea, with validated Scheimpflug data and OCT imaging. The system integrates seamlessly with the existing Pentacam®...REVO OCT - Fundus Camera
Comprehensive glaucoma analytical tools for quantification of the Nerve Fiber Layer, Ganglion Layer and Optic Head with DDLS enable the user to perform precise diagnosis and monitoring of glaucoma over time. With the golden standard 14 optic nerve parameters and...Solix FullRange OCT
SOLIX is a multi-modal OCT. It features high-speed scanning of 120,000 A-scans per second, for a FullRange field of view that is wide and deep, yet does not sacrifice image clarity and resolution. Anterior & posterior OCT OCT & OCTA...
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...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...
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...
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....
OCT findings after strabismus surgery for macular, choroidal and nerve fibre thickness
This study used OCT to investigate the changes in the central macular thickness, subfoveal choroidal thickness (SFCT) and retinal nerve fibre layer (RNFL) after horizontal rectus surgery for patients with strabismus. This was a retrospective study and patients were grouped...
