Given the well-documented relationship between posterior pole nonperfusion and DR progression, it is logical that greater peripheral nonperfusion on ultra-widefield fluorescein angiography is also associated with higher likelihood of PDR.
Dunfermline-based Optos, a leading provider of retinal imaging devices, kept its crown at this year’s Optician Awards in Birmingham (30th March), claiming the title of Optical Supplier of the Year for the second time in a row.
Expanding the role of medical retina virtual clinics using multimodal ultra-widefield and optical coherence tomography imaging
Ultra-widefield fluorescein angiography revealed distinct fundus-wide patterns of vascular damage, which were progressive in nature in eyes treated with iodine-125 brachytherapy for uveal melanoma and correlated with signs of progressive vascular injury. This grading scheme may have prognostic value to predict the progression of radiation retinopathy and to prognosticate visual outcomes in patients undergoing brachytherapy.

New High-Tech Eye Exam Helps Doctors Detect Serious Health Issues Much Sooner — Even Breast Cancer
Optos Plc, une filiale de Nikon Corporation (Japon) et Amydis, Inc. ont annoncé aujourd’hui une alliance clinique portant sur le développement d’un test oculaire par Amydis pour détecter la maladie d’Alzheimer. Amydis a développé une gamme de composés permettant de détecter les protéines amyloïdes qui seront visualisées grâce à l’optomap, le système d’imagerie rétinienne ultra-grand champ d’Optos, leader dans son domaine, afin de diagnostiquer la maladie d’Alzheimer chez les patients.
Researchers from Queen’s University Belfast have shown for the first time that the eye could be a surrogate for brain degeneration like Alzheimer’s disease (AD).
These research results have recently been published in the Journal of Ophthalmic Research and is the first clinical study showing a potential for peripheral retinal imaging to be used in monitoring AD and potentially other neurodegenerative diseases.
The team, led by Dr Imre Lengyel, Senior Lecturer and Researcher at the School of Medicine Dentistry and Biomedical Sciences at Queen’s University have found that by examining the eye we might be able to reflect on what might be taking place in the brain.
The work was carried out alongside health professionals and care providers for AD patients and explored whether there are manifestations of AD in the eye.
Based on laboratory observations the team hypothesized that changes in the peripheral retina could be important to explore the association between the eye and the brain.
Using ultra-widefield imaging technology developed by Optos Plc, the team found that there are indeed several changes that seem to be, especially in the peripheral retina, associated with this debilitating condition.
Ultra-widefield angiography has been successfully used without sedation for evaluation of children with various pediatric retinal diseases such as Coats disease, familial exudative vitreoretinopathy, and retinopathy of prematurity.
Today, Monday 14th May 2018, Optos are joining BBGR (Nikon Lenswear France)* for their annual Vision Van – the ‘Tour de France’ to highlight the importance of regular eye tests to maintain good vision. The Vision Van is an optometry practice on wheels fully equipped with an Optos Daytona plus and full eye testing equipment. The van will provide free eye tests for local communities in six towns and cities across France to educate visitors the importance of regular, thorough eye health checks.
Optos plc, a Nikon company, unveils Monaco, its next generation ultra-widefield imaging device with OCT capabilities for the ophthalmic market
As a world leading manufacturer of retinal imaging technology, Optos was crowned Optical Supplier of the Year at the Optician Awards 2018 in Birmingham on Saturday 14th April. The awards are recognised as the benchmark of excellence in the UK optical community and showcase the best in achievement, ability and performance.
Results suggest an association between Dark Adaptation and the presence of peripheral reticular pigmentary changes, as well as the presence of a peripheral mottled decreased FAF pattern. This provides new insights on the clinical significance of peripheral changes in AMD, and their contribution to impairments on Dark Adaptation.
UWF retinal imaging revealed a significant association between AD and peripheral hard drusen formation and changes to the vasculature beyond the posterior pole, at BL and
after clinical progression over 2 years, suggesting that monitoring pathological changes in the peripheral retina might become a valuable tool in AD monitoring.
After being among the finalists for ‘Product of the Year’ for Daytona plus at the 2018 AOP Awards, we are pleased to announce that Optos has been shortlisted as ‘2018 Optical Supplier of the Year’ at the upcoming Optician Awards, “the benchmark of excellence in the Optical community” (theopticianawards.co.uk).
This year’s awards are even more exciting for Optos as we learn that a range of our UK customers have also made the finals across several categories.
After conversion to ranibizumab (from bevacizumab) in eyes with persistent DME refractory to bevacizumab, significant functional and anatomic improvements were noted. Qualitative analysis of ultra-widefield fluorescein angiography images was performed to identify retinal vascular pathologic features, specifically by observing the presence of vascular leakage, neovascularization, macular ischemia, and peripheral ischemia. The prevalence of macular ischemia was 33.3% at baseline and remained stable at study completion. Finally, the proportion of peripheral ischemia observed in participants increased from 66.7% at baseline to 70.3% at month 12, although the incidence of any leakage remained stable at month 12.
UWF Imaging Contributes to Earlier Disease Detection - New research confirms agreement with 7 standard field imaging
Prospective, observational study including patients with sickle cell disease. All patients underwent dilated fundus examination by a fellowship-trained retina specialist, as well as UWF fundus photography (FF) and fluorescein angiography (FA). Sickle retinopathy stage and treatment recommendation per eye were determined after clinical examination, UWF-FF, and UWF-FA, respectively, and differences in retinopathy stage and treatment recommendation were compared.
Conclusion: Ultra-widefield imaging detects a higher stage of sickle cell retinopathy compared with clinical examination alone, but these differences may not be clinically significant.
The patient presented with 20 years of exposure to HCQ, at a daily dose of 5.2mg/kg of actual body weight, and manifested a pericentral-only phenotype of HCQ toxicity, as demonstrated with detailed structural and functional testing.
optomap examinations are a convenient and feasible method to determine fundus pathological changes in myopic patients, especially for patients who can not endure pupil dilation. Compared to the Goldmann three-mirror contact lens examination, the detection rate with optomap was 91.73%% for retinal lesions, while the detection rate of mydriatic slit-lamp lens exams was 81.20%.
In a primary health care clinic, 632 healthy subjects underwent UWF imaging during annual health screening. optomap images detected peripheral retinal pathology in 18.4% that was not visible on corresponding single-field (45°) images. UWF imaging is feasible in a primary care setting, allows improved visualization of peripheral retinal pathology, and may therefore be useful for telemedicine screening.
Wide-field retinal imaging revealed the presence of peripheral pigmented retinal lesions resembling CHRPE lesions in a subset of patients with genetically confirmed Stargardt disease. Presence of these lesions may be associated with severe phenotypes of the disease.
The present study (1,024 subjects) has shown the effectiveness of DR screening using UWF fundus camera detecting 9.27% of patients with DR. It has also shown the effectiveness of trained nursing personnel taking fundus pictures. First, UWF imaging has a fast learning curve and it is quick to take the picture. Second, widefield view is greater than the 7-field photography enabling more DR lesions to be detected. And third, images can be manipulated in terms of red-free, infra-red and image zoom. Hence, the present telemedicine model has demonstrated that in a multi-specialty private hospital, DR screening can be effective using UWF fundus camera.
Peripheral vascular leakage (PVL) is a possible independent driver of treatment augmentation. Patients with PVL were four-times more likely to have treatment augmented after adjusting for baseline presence of CME, diffuse vascular leakage and clinical grading of uveitis activity. This suggests that PVL may have influenced the decision to augment therapy in patients.
UWFFA identifies retinal vascular pathology in intermediate uveitis not present on clinical examination. Diffuse retinal vascular leakage was associated with worse visual acuity when compared to peripheral and no leakage patterns.
Grading of UWF imaging has high reproducibility in evaluating vertical cup-to-disc ratio and agreement with stereoscopic optic disc imaging and may be suitable for glaucoma diagnosis in situations where colour digital stereoscopy is not available.
Peripheral retinal changes were observed peripheral to the equator in more than 40% of analyzed eyes in patients with and without AMD. Drusen, reticular pigmentary change and paving stone degeneration occur significantly more frequently in eyes with AMD compared to healthy eyes.
This year is the 25th anniversary for Optos. With such a significant milestone, it is customary to reflect on the journey. It all began when Douglas Anderson, our Founder set out to commercialize a patient-friendly product that encompassed a digital widefield image of the retina in a single capture. His young son, Leif was the impetus behind this mission. Whilst he had been receiving regular eye exams, the doctor was unable to examine Leif’s entire retina and he became blind in one eye when a peripheral retinal detachment went undetected. From that point on, the mission of saving sight and saving lives was engrained in the fabric of our culture and has become the cornerstone of our vision to be The Retina Company.
Douglas Anderson, the founder of Optos, reflects on a 25-year-long journey to bring ultra-widefield imaging into the consulting room, inspired by the experience of his own son. Interview conducted by Optician.
Specific AMD features in UWF images were graded. Standardised grids were used to record the spatial location of AMD features, including RPD. We found no evidence to support an association between coronary artery disease and RPD. RPD was strongly associated with intermediate AMD features.
Demonstrated that Coats' disease is a highly asymmetric bilateral disease and that UWF imaging is able to identify more retinal pathology than standard fundus imaging, thus guiding proper retinal photocoagulation. All clinically affected eyes exhibited retinal pathology at UWF imaging with the temporal sector most involved followed by the inferior, nasal, superior and macula.
The incidence of diabetes in the US population has increased more than fourfold over the last several decades and a high proportion of these patients manifest diabetic eye disease, including diabetic retinopathy (DR) and diabetic macular edema (DME).
