Retinal vein occlusion (RVO) is a restriction or blockage of blood flow leaving the retina and is the second most common retinal vascular disorder after diabetic retinopathy¹. Causing varying degrees of vision loss, both central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) can be complicated by macular edema that can lead to total blindness.

RVO has a complex pathology, significant associated risk factors (e.g. age, hypertension, diabetic retinopathy, ischemic heart disease), and its treatment of associated macular edema may require no more than a single course treatment in some cases, but in others recurrent edema may necessitate one or more repeated courses of treatment.

One technology that is helping to advance the understanding and management of RVO is ultra-widefield retinal imaging (UWF^™), which provides up to a 200 degree visualization of the retinal periphery. RVO is now being treated and studied using UWF retinal imaging, and data about the significance of RVO-associated pathology in the retinal periphery are being accumulated.

UWF retinal imaging is performed by a specially designed scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image covering 200° (or about 82%) of the retina. By comparison, conventional 7 standard …

The expanding role of optometrists as primary eye care providers is also increasing expectations about the level of diagnostic and follow-up care. Whether it’s screening and monitoring hypertensive or diabetic patients, diagnosing a patient’s vision impairment, or uncovering pathology during a routine examination, optometric practices are expected to know more and do more about the ocular health of their patients.

Many optometrists may be meeting these expectations by utilizing ultra-widefield (UWF^™) retinal imaging as a routine part of their practices. Along with improving patient experience and practice productivity, UWF retinal imaging gives these practitioners a powerful tool that is improving their practices’ overall optometric care.

UWF Retinal Imaging – A Versatile Imaging Platform

UWF retinal imaging provides practitioners with a versatile screening platform that can strengthen their ability to identify ocular and systemic disease while enabling more comprehensive and accurate treatment plan.

— One important capability offered by UWF retinal imaging is comprehensive and detailed visualization of the retinal periphery. As this technology proliferates throughout the eye care community, more studies are finding that pathologies of the retinal periphery are important to the understanding, diagnosis and treatment of a variety of conditions. One recent report …

Optometric practices face growing and more complex patient loads as they support the special needs of an aging population, an increase in diabetic patients and the complications associated with their condition, and manage patient flow so to strike a balance between patient experience and staff productivity. Many optometrists are satisfying all of these demands by incorporating ultra-widefield (UWF^™) retinal imaging into their practices.

About Ultra-Widefield Retinal Imaging

UWF retinal imaging is performed by a specially designed, table-top scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image covering 200° (or about 82%) of the retina. (this compares to other imaging techniques with fields of view typically under 45°).

The SLO simultaneously scans the retina using two low-power lasers (red and green) that enable high-resolution, color imaging of retinal substructures. The resulting UWF high resolution digital image – the optomap – is produced in a single capture without pupil dilation. Tabletop systems designed for optometric practice (Daytona) provide both UWF color imaging and UWF autofluorescence modalities in a single scan.

Unlike routine slit lamp examinations, optomap can be performed by a trained technician. The image is captured in less than a second using automatic prompts that position the patient for an accurately. …

The need to increase the rate and accessibility of ocular health screenings is significant. For example, of the 415 million adults worldwide who are afflicted with diabetes, 45 percent are undiagnosed. A large percentage of these undiagnosed individuals will develop diabetic retinopathy (DR) and DME diabetic macular edema (DME). Also important is the diagnosis of other conditions, many of which are found in aging populations, including age-related macular edema (AMD), branch retinal vein occlusion, glaucoma, and cataracts.

One way to widen the availability of ocular health screenings is through telehealth and telemedicine programs. These initiatives are growing worldwide as stakeholders in the health community take advantage of advances in medical and communications technology. One such innovation with particular utility in ocular telehealth is ultra-widefield (UWF™) retinal imaging, which offers an effective, rapid, and easy-to-use means bringing state-of-the-art diagnostics to underserved populations. This technology, developed by Optos, has been deployed in a variety of telehealth settings.

More than 400 million people across the globe deal with diabetes. An additional 200 million are expected to be diagnosed between now and 2040, and up to a third of these patients will likely develop diabetic retinopathy (DR)¹.

These increasing health challenges are driving the need for improved techniques to diagnosis and treat both DR and its common complications like diabetic macular edema (DME). One diagnostic tool – the visualization of the retinal periphery using ultra-widefield (UWF^™) retinal imaging – is providing the ophthalmic community with important insights about the pathology, progression and treatment of DR and associated complications.

About UWF Retinal Imaging

UWF imaging is performed by a specially-designed scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image capturing 200° or 82% of the retina. The SLO simultaneously uses two low-power lasers (red and green) that enable high-resolution, color imaging of retinal substructures.

Along with UWF color imaging, the technology also supports UWF fluorescein angiography (FA), UWF fundus autofluorescence (FAF), and UWF indocyanine green angiography (ICG).

Conventional 7 standard field (7SF) ETDRS photographs produce a comparatively narrow view (45° or less) of the center-portion of the retina. Peripheral portions are not imaged.

UWF Retinal Imaging’s Impact on DR …

A common complication arising from diabetic vitrectomy for the treatment of proliferative diabetic retinopathy (DR) is recurrent post vitrectomy diabetic vitreous hemorrhage (PVDVH). A recent study¹ using ultra-widefield fluorescein angiography (UWF FA) has generated new insights into the etiology of recurrent PVDVH. The study results also suggest that imaging of the peripheral retina may provide practitioners with superior, actionable post-operative information compared to conventional imaging techniques.

Multimodal UWF Retinal Imaging

UWF retinal imaging is performed using a specially-designed scanning laser ophthalmoscope (SLO) that generates a high-resolution digital image – optomap – which captures 200° (or about 82%) of the retina. By contrast, conventional ETDRS 7 standard field (7SF) photographs produce a relatively narrow view (45° or less) of the center-portion of the retina.

For UWF color imaging, the SLO simultaneously scans the retina with two low-power lasers (red and green) that enable high resolution, color imaging of retinal substructures. The scan is completed in a single capture in less than a second, often without pupil dilation required. Along with UWF color imaging, the technology also supports ultra-widefield fluorescein angiography (FA), UWF fundus autofluorescence (FAF), and UWF indocyanine green chorioangiography (ICG).

January is National Glaucoma Awareness month and in efforts to help educate the public on the disease here are a few facts you should know pertaining to your eye health:

Nearly 3 million people over the age of 40 have glaucoma and as the population ages the number is projected to grow steadily, increasing by nearly 50% to 4.3 million by 2032 according to the Prevent Blindness “Future of Vision: Forecasting the Prevalence and Costs of Vision Problems” report.

Glaucoma is often called the “the sneak thief of sight” because most people don’t notice the early symptoms. However, if it is detected and treated early enough vision loss may be decreased. Risk factors that increase your odds of glaucoma include: extreme nearsightedness, aging eyes, and a family history. For the best chance of early detection, regular, comprehensive eye exams should be conducted even if you have no symptoms.

It’s imperative to act fast to protect your vision! If you wait until after you’ve already experienced some vision loss to seek help you may not be able to restore your eye sight even with surgery or treatment – glaucoma typically affects your peripheral vision first. As the only ultra-widefield retinal imaging technology with a 200 degree view …

The statistics are clear. Over the next decade optometric and ophthalmic practices in North America, Europe and throughout the developed world will identify and treat an increasing number of patients with diabetes and diabetic retinopathy (DR). There are currently more than 40 million people in North America with diabetes and that number is expected to grow to over 50 million by 2025.¹ In Europe, the number of those afflicted with the disease—currently over 60 million – will also see significant growth.² These trends present practitioners with real challenges – first, how to more efficiently screen this large and growing population for signs of DR, and second, how to provide more informed and effective treatment at all stages of the disease.

Many practitioners are rising to these challenges with the help of a technology that has unique, proven capabilities in improving DR diagnosis and management – ultra-widefield (UWF™) retinal imaging.

The increasing use of ultra-widefield (UWF^™) retinal imaging is giving the optometric and ophthalmic communities a more comprehensive diagnostic platform as well as a powerful tool to explore the pathology and progression of a broad range of retinal diseases and conditions.

The diagnosis and study of diabetic retinopathy (DR) is one of several fields where UWF imaging is having particular impact. It’s estimated that over 400 million people across the globe are afflicted with diabetes and that number is expected to increase to over 600 million by 2040. As many as a third of those diagnosed with diabetes will also develop DR[1], a leading cause for blindness in adults. This growth is spurring the need for improved techniques for DR screening and diagnosis.

Protecting your eyes from the harsh effects of UV rays is just as important in January as it is in June. A common misconception with eye safety is believing that eye damage can not occur in the winter months and that eye safety practices can go on holiday until next year. Sun exposure can increase the development of cataracts, and cause growths on the eye regardless of the season.

The sun can have a seemingly harsh reflection off the snow in the winter and it’s critical to take the necessary precautions in protecting yourself such as wearing hats, sunscreen, goggles or other UV protective eyewear. Studies have found that exposure to UV radiation can even be high on cloudy days with the northern hemisphere having its highest exposure at midday. Dr. Anne Sumers, a practicing ophthalmologist in Ridgewood, NJ and spokeswoman for the American Academy of Ophthalmologist states, “Sunlight reflected off the snow can actually sunburn the cornea in the winter.”

With the heart of winter just around the corner for most of the US, here’s a few tips on what you can do to stay ahead of the weather and protect your eyes:

Wear sunglasses
