What a Difference a Daytona Makes

Posted on Wednesday, November 15, 2017

The Daytona from Optos captures 200° or 82 percent of the retina in a single ultra-widefield (UWF) optomap® image in less than half a second. The built-in eye-steering technology allows non-mydriatic, visualization and imaging of all quadrants beyond the standard 200° view,1 which can make it a valuable technology in early peripheral pathology detection, timely decision-making and, ultimately, sight preservation.

Dr. Nicole Kish has been using the Daytona in her Visionworks practice (Norman, OK) for more than a year now and has seen the value of its integration into the practice workflow protocols. With the full support of an Optos account manager, Dr. Kish has been able to incorporate her entire staff into the pre-testing process, which, in turn, reduces clinical “chair time” and increases the time spent talking with patients.2 According to Dr. Kish UWF imaging has supported her ability to identify early peripheral changes in patients suspected of having undiagnosed diabetes.

The educational value of the optomap system was a big selling point for Dr. Kish. She has been able to educate large numbers of patients about their eye conditions, providing them with “…a level of education and images of their own eyes they’ve never seen.”

November is Diabetic Eye Disease Awareness Month

Posted on Wednesday, November 8, 2017

Diabetic eye disease is a leading cause of blindness and vision loss,1 and, according to the World Health Organization, the incidence of diabetes worldwide is escalating.2 It is estimated that by the year 2035, the number of people worldwide with diabetes will have soared to almost 600 million.3 The National Eye Institute (NEI) reports that there are another 86 million American adults who have pre-diabetes.

Diabetic eye disease describes a group of eye conditions that include diabetic retinopathy (DR), glaucoma, diabetic macular edema and cataracts. DR is often reported as the most common form of diabetic eye disease. It is a serious complication of diabetes mellitus (DM), afflicting one third of all people with the disease, and it is the leading cause of blindness among the working population in the world.4

In its report, “Diabetic Eye Disease Projected to Increase Among U.S. Population,” the NEI states that there are currently 7.7 million people ages 40 and older who have DR, and this number is expected to increase to around 11 million by the year 2030. With advances in technology and medicine, adequate management and regular eye examinations, sight loss associated with diabetes may be prevented in 98 percent of …

The Role of UWF Imaging in the Effective Management of Non-Infectious Uveitis

Posted on Friday, October 27, 2017

Uveitis describes a group of intra-ocular inflammatory conditions, where etiology is diverse and may be characterized by inflammation of the uveal tract or indirect inflammation of adjacent tissues1. In his paper, A Long-Term Game Plan for Non-Infectious Uveitis, Sam S. Dahr, MD, reports that the majority of uveitis cases seen in daily practice are non-infectious and idiopathic in origin. This report estimates that the disease affects approximately 300,000 American adults and 22,000 American children. Of great concern for the young, is the lack of proper treatment in the early stages of the disease, which can be attributed to a poor visual outcome 2.

Proactive and effective management of non-infectious uveitis relies heavily upon developing a therapeutic strategy and a long-term plan, which may involve systemic therapy, patient counseling, close follow-up, dosing adjustments, combination therapy, and consultation with rheumatologists. In his report, however, Sam S. Dahr, MD, suggests that imaging metrics are “…more powerful than any blood test the rheumatologist can order to monitor response”; positioning ophthalmologists to “… bear the decision-making responsibility for these patients.” Many patients with non-infectious uveitis suffer “…inflammatory breakthroughs during systemic therapy, most of which tend to be fairly mild and treatable with topical, injected or …

Home Eye Safety Month and the Value of optomap Technology

Posted on Wednesday, October 4, 2017

A survey conducted by the American Academy of Ophthalmology (AAO) highlighted a significant discrepancy between the perceived versus the actual danger of the home environment being a threat for eye injuries1. The survey determined that fewer than half of the respondents saw the home environment as a potential site for eye injuries, and those that did cited the garden and garage as the most dangerous places. In reality, however, each year it is estimated that 50 percent of all eye injuries occur in the home and most could have been prevented if proper eye protection had been worn2. Sadly, only 35 percent of people surveyed claimed to follow a practice of home eye safety by always wearing eye protection when it was needed.

Statistics show that there are several ways that people are at risk of eye injury in their homes. The AAO reported that 125,000 eye injuries occur each year due to accidents involving common household products, such as bleach and oven cleaner. Unprotected eyes are also at risk where there are things that move at high speed, such as debris from yard work, power tools or nails being hammered into hard surfaces and even champagne corks.

Athletes and the Eye: Eye Injuries and Using the Retina to Detect Systemic and Ocular Pathology and Disease

Posted on Wednesday, September 27, 2017

Athletes of all levels need to protect themselves from injury. Injuries are unfortunately a part of playing sports – anyone from weekend warriors to professionals, has probably nursed some sort of injury. In some cases, these injuries happen directly to the eye, from orbital blowout fracture, ruptured globe, or a detached retina and some can be detected, along with other types of ocular and systemic pathology, by looking at the health of the eye.

There have been, and continue to be, many studies in the area of sports-related eye trauma. And with more and more interest in the effects of concussions on athletes, seeing “inside” the eye is becoming increasingly important. An x-ray, MRI, CT scan will tell you if something is broken and may confirm a diagnosis of concussion. But what about the effects of repetitive concussive injury? Can that be detected by imaging the eye itself? According to the Centers for Disease Control, up to 3.8 million sports-related concussions occur each year. And detecting these injuries is not always straightforward or based exclusively on objective signs and symptoms. Or what about treating the whole athlete and monitoring systemic as well as ocular health?

Because the retina is the …

September is Sports Eye Safety Month – Utilizing optomap to Detect, Manage, and Treat Sports-related Eye Injuries

Posted on Wednesday, September 13, 2017

Sports-related eye injuries often result in vision loss, and are the leading cause of blindness in children.1 According to the National Eye Institute (NEI) and the National Eye Health Education Program (NEHEP), in the United States, sports-related eye injuries account for over 100,000 physician visits per year at an estimated cost of $175 million. Since most eye injuries are preventable, more sight may be preserved by exercising injury prevention techniques.

Protective eyewear is vitally important in the prevention of injury, but the NEI and NEHEP also strongly recommend that all people who participate in sporting activities have comprehensive eye exams as part of their regular physical examinations, especially for those with pre-existing eye conditions. optomap® has a huge part to play in facilitating difficult eye examinations, and in supporting the early detection of peripheral retinal complications following sports-related eye injuries.

Direct, blunt force injury to the eye often causes swelling for several days, making a comprehensive retinal examination difficult. Early assessment of the eye is imperative in saving sight, as these injuries cause a high risk of retinal detachment or retinal bleed. The half-second capture speed and non-mydriatic advantages of optomap technology allow for more timely, less invasive access to …

UWF Imaging May Boost Early Detection of Choroidal Nevi

Posted on Friday, September 1, 2017

It is estimated that in the United States, choroidal nevi can be found in 4.6 to 7.9 percent of Caucasian individuals1 and that one in approximately 8,000 of these nevi transform into melanoma2. It is this rare ability that makes these lesions clinically significant.

Choroidal nevi are typically discovered during routine dilated fundus examinations and are usually asymptomatic. However, some may be associated with central and peripheral vision loss secondary to subretinal fluid, cystoid retinal edema or, rarely, neovascularization3. Choroidal melanoma also tend to be asymptomatic, but are more likely to be symptomatic than benign nevi, presenting as decreased vision, flashes or floaters.

In their study, Cheung et al. suggest that there are phenotypical markers and environmental risk factors that predispose a person to developing choroidal melanoma. A later study4, using optomap®, determined that choroidal nevi were also present in subjects who did not conform to a particular phenotype. Gordon-Shaag et al. concluded that it was the expanded view (200°) of ultra-widefield (UWF™) technology that improved their ability to locate nevi. This was further supported by Brett et al., who concluded that the optomap was the most effective device for pinpointing choroidal nevi5.

Historically, the challenge has been to locate …

Use of UWF Imaging During Routine Eye Exams May Increase the Early Detection of Choroidal Nevi

Posted on Friday, August 25, 2017

Choroidal nevi are commonly reported as incidental findings in asymptomatic patients during routine eye exams. Nevi on the retina, similar to “freckles” on the skin, should be monitored for changes as they may turn in to melanoma1.

With the increased use of ultra-widefield (UWF™) imaging, reports of secondary findings of choroidal nevi are increasing. Because optomap®, captures up to 82% or 200° of the retina in a single image, it can impact the ability of eyecare professionals to detect previously unnoticed retinal anomalies. Once found, these anomalies may be closely monitored and differentiated using the optomap 3-in-1 color depth imaging in conjunction with optomap af, the latter which highlights lipofuscin in the retinal pigment epithelium (RPE) and is particularly useful for the detection of choroidal neoplasms and nevi2.

Dr. Bryan Stoller reported using optomap to monitor Jeffry, a 54 year-old man with glaucoma3. Jeffry had his intra-ocular pressure (IOP) checked every four months, and returned annually for UWF imaging of his optic nerve and a small choroidal nevus. During one visit, while using optomap af, Dr. Stoller noticed that the nevus had started to autofluoresce. Although the choroidal nevus, measuring three disc diameters (DD), had not increased in size, …

The Importance of Back to School Eye Exams

Posted on Thursday, August 10, 2017

Pop quiz time: What’s one of the most important things you need to do as a parent before the new school year rolls around? The answer: Schedule back to school eye exams for your whole family!

 

Back to School Eye Exams are a Must

There’s little question about it: Back to school eye exams are a critical component to your child’s health and quality of life. Why? Because your child’s vision will affect virtually every aspect of academics, athletics, and extracurricular activities.

 

Interestingly, many common eye problems first develop in young, school-aged children. If left undiagnosed and untreated, these visual problems can disrupt your child’s ability to pay attention in class. Unfortunately, in some cases, children with visual problems end up being misdiagnosed with ADD/ADHD or another type of learning disorder. Hence, it is essential to make sure that your child’s eyesight is in top condition. This ensures that all of their unique needs are met, and that they are able to participate to the best of their ability in school.

 

So, what kind of eye problems will an eye care provider look for in your child?

UWF Imaging Supports Early Diagnosis of Dry Age-related Macular Degeneration

Posted on Thursday, August 3, 2017

Age-related macular degeneration (AMD) is one of the world’s leading causes of central vision loss in industrial nations, causing significant visual morbidity. Non-exudative AMD accounts for approximately 90% of all reported cases.

There is a growing body of evidence suggesting that there may be early indicators preceding the development of AMD. Over 30 years ago, while investigating reticular degeneration of the pigment epithelium (RDPE), Lewis et al, discovered a correlation between the characteristics of macular degenerative changes and RDPE. One of their recommendations supported the value of observing the peripheral retina, when assessing patients with macular degenerative abnormalities1.

 

Understanding the relevance of peripheral retinal abnormalities, to disease progression relating to AMD and other retinal conditions, continues to evidence the value of ultra-widefield (UWF) imaging in this process. In the 12-year follow-up of subjects from the Reykjavik Eye Study, Lengyel et al2 evaluated subjects using optomap® color and autofluorescence (AF) imaging.

 

The peripheral retina was phenotyped using categories defined in the International Classification of AMD which was developed to characterize the macula. The population sample was 576 subjects. Of the eyes examined, 81.1% had AMD-like changes in the macula. From this sample, 13.6% of subjects were noted to have …
