Optos plc, the leading medical retinal imaging company, part of Nikon Corporation, is pleased to announce the launch of Silverstone at the American Academy of Ophthalmology, San Francisco, CA.

Silverstone is the first of its kind, combining world-leading ultra-widefield retinal imaging with integrated, image-guided, swept source OCT.  Silverstone produces a 200° single capture optomap^® image with guided OCT allowing advanced OCT imaging anywhere across the retina, from posterior pole to far periphery.  This provides unparalleled UWF guided multimodal imaging in support of detection, investigation and monitoring of retinal disease.

Silverstone provides greater imaging functionality and expands the Company’s product portfolio for ophthalmic markets.  It combines colour, autofluorescence (AF), fluorescein (FA) and Indocyanine Green (ICG) angiography with Swept Source OCT imaging capabilities.  A comprehensive exam that includes an ultra-widefield optomap^® image has been shown in clinical studies to enhance pathology detection and disease management, as well as to improve clinic flow.  Now by integrating swept source OCT, Silverstone further facilitates examination of the retina from vitreous through the choroidal-scleral interface and helps guide treatment decisions.

David M. Brown, MD from Retina Consultants of Houston in Houston, TX, remarked, “Silverstone is very exciting.  It’s definitely the …

World Sight Day (WSD) is an annual day of awareness held on the second Thursday of October each year.  WSD aims to focus global attention on blindness and vision impairment.  The International Agency for the Prevention of Blindness (IAPB) members work together to raise public awareness of blindness and vision impairment, influence governments to participate and designate funds for national blindness prevention funds, and to educate target audiences about blindness prevention.  World Sight Day 2019 takes place on October 10^th. This year’s theme and call to action is “Vision First!”.  

Of all the people suffering from blindness or poor vision, more than a billion people suffer because they do not have access to proper eye care.  This year’s mission urges everyone to find solutions to ensure that everyone, everywhere has access to proper eye care.

Continued studies conducted by the IAPB have concluded that 80% of eyes can be saved from blindness, given the proper comprehensive care and diagnosis. Additional facts from these studies include

285 million people are estimated to be visually impaired worldwide: 39 million are blind and 246 million have low vision.About 90% of the world’s visually impaired live in low-income settings.80% of all visual …

Results from a recent publication call for the use of consistent nomenclature when describing the field of view captured by retinal images. The International Widefield Imaging Study Group has proposed the need for consistent nomenclature for widefield and ultra-widefield imaging based on normal anatomic landmarks. When describing the area captured by an imaging modality, it is important to be consistent in meaning so the capabilities of the technology are clear to the reader.

The panel defines ultra-widefield as images showing retinal anatomy anterior to the vortex vein ampullae in all four quadrants.  Widefield is defined as an image centered on the fovea and includes the retina in all four quadrants posterior to and including the vortex vein ampullae. The panel recommends this standardized nomenclature for use in future publications¹.

Over the last decade, many large studies have underlined the importance of appropriately imaging the periphery to support the detection and management of disease in a variety of areas including telemedicine screening^2,3,4, diabetic retinopathy^5,6, age-related maculardegeneration⁷, vascular disease⁸, pediatric retinal disease⁹, inflammatory disease^10,11,12 and even some systemic diseases.  Consistently, optomap imaging has been demonstrated to capture the widest field of view in a single capture of any imaging technology^14,15,16,17.

Age-related macular degeneration (AMD) is a leading cause of blindness in the United States, affecting most commonly, people over the age of 60 with increasing chances as you age, if you are overweight or if you have a family history of AMD.    

As we approach our golden years, we are at a higher risk for particular eye diseases including age-related macular degeneration, cataracts, diabetic retinopathy, glaucoma, as well as eye conditions such as dry eye and low vision.  More than 40 million Americans are currently 65 years or older, this number is expected to grow to more than 88 million by 2050 and not coincidentally, the number of Americans with age-related eye diseases is expected to double.  Early detection and treatment are key to saving sight.

For some, AMD advances so slowly that vision loss does not occur for a long time. In others, the disease progresses faster and may lead to a loss of vision in one or both eyes. The loss of central vision in AMD can interfere with simple everyday activities, such as the ability to see faces, drive, read, write, or do close work, such as cooking or fixing things around the house.

As we continue to recognize August as Children’s Eye Health and Safety month, it’s important to understand the importance of eye exams, and the utilization of the highest-level technology in pediatric screening.  Optos ultra-widefield (UWF™) imaging technology is making great strides in diagnosing and treating eye problems in children and infants. Due to the cutting-edge modalities and ease-of-operation with an optomap® exam, signs of retinal disease can be found in the periphery, often before children and infants become symptomatic. Many vision problems begin at an early age, so it’s important for children to receive proper eye care.   optomap was founded by Douglas Anderson after his then five-year-old son Leif went blind in one eye when a retinal detachment was detected too late. Although his son was having regular eye exams, routine exams were uncomfortable, especially for a child, which made it impossible for the doctor to conduct a complete exam and view the entire retina. He set out to create a way of non-invasively capturing as much of the retina as possible.in a single capture. Results from several published clinical studies suggest that optomap is an essential element to the screening and management of pediatric patients.  While traditional fundus imaging is a multi-stage effort …

With school starting up again, and lists including everything from the essential newest styles to school supplies – one item to make sure is on the list is your child’s comprehensive eye exam.  While we may notice subtle changes in appearance as our children grow and develop, there are many changes also occurring within the eye that are unseen.  This marks the importance of annual eye exams that will assist in monitoring the development of your child’s vision as they grow.  Routine vision screening or eye examination at an early age is very important to detect risk factors, such as lazy eye, crossed eyes, and color blindness that can potentially cause irreversible loss of vision or blindness.  A majority of vision impairment issues go undetected since young children with impaired vision are often unaware of their vision issues—it is, after all, how they’ve always seen things. It is on us as parents and educators to look for signs of visual impairment.

Although schools generally do some basic testing of children’s vision, there is no doctor to perform a comprehensive exam or diagnose problems with your child’s eyesight.  According to experts, nearly 90 percent of what is taught in school is …

As the summer heats up many of us are eager to enjoy the warmth of the sun and the activities that go along with it.  While continued awareness of the importance of UV protective clothing and sunscreen exists, there is a lack of emphasis on the impacts the sun and UV exposure has on the eyes.  UV damage to the eyes is known as the “invisible threat” and its impacts are measured and classified by the strength of the UV ray in nanometers (nm).  

UVC: These rays are below 280 nm. The upper atmosphere absorbs these, so they do not reach us, therefore protection from these rays is not overly necessary.

UVB: These are between 315 – 380 nm. These manage to make it to the earth’s surface and are notorious for damaging sight. They can cause snow blindness but are notably responsible for sunburn and several types of skin cancer. Research has shown that these rays are strongest during the summer and at higher altitudes.

UVA: These are the most dangerous being 315 – 380 nm. They are known for causing chronic eye damage. Studies have indicated that these rays get absorbed by the lenses of our eyes …

One of our favorite times of the year in the United States surrounded by cookouts, pool parties, friends and family, the 4th of July is upon us.  In addition to all the splendor, the month surrounding July 4th festivities also brings an increase of fireworks displays as well as an increase in firework-related injuries.  Prevent Blindness America and the American Academy of Blindness sponsor June and July as Fireworks Eye Safety Months to raise awareness of the dangers, as well as, the safe protocols for viewing or handling pyrotechnic displays or devices. Most fireworks-related injuries occur during the month of July, and according to the most recent Consumer Product Safety Commission report, 14% of fireworks injuries have been eye injuries occurring mostly in children between the ages of 10 and 14.   It is easy for any of us to get caught up in all the excitement and activity or become distracted by hosting responsibilities, conversations, and crowds.  Take into consideration, as well, that these festivities and shows are generally conducted past dusk and simply navigating an event with numerous people and smoke can become challenging, let alone successfully dodging the sparkler-wielding children. Keep yourself, your children and your eyes safe this summer …

Helping You See Better: June is Cataract Awareness Month

Presently, cataracts are considered the leading cause of vision loss in the United States.  24 million Americans, over the age of 40 are affected by cataracts.  This June, Optos joins Prevent Blindness America in observing Cataract Awareness Month to aid in the education surrounding cataracts, and what you should know.

What are Cataracts?

Inside our eyes, we have a natural lens. The lens refracts light rays that come into the eye to help us see. The lens should be clear, like the top lens in the illustration. With the presence of cataracts, the lens has become cloudy, much like looking through a foggy or dusty car windshield. Things look blurry, hazy or less colorful with a cataract.

Vision changes you may notice if you have a cataract:

Having blurry vision Seeing double Extra sensitive to light Having trouble seeing well at night, or needing more light while reading Seeing bright colors as faded or yellow instead

What Causes Cataracts?

Exact causes of a cataract are unknown, most often they are a part of getting older.  There are some key possible risk factors that have been identified in those at risk, such …
