Optos UWF autofluorescence helps classify AMD and predict progression

Posted on Wednesday, June 26, 2013

Examining the periphery with UWF autofluorescence (UWFAF) reveals patterns that suggest a new classification system for AMD and provide evidence of disease progression. A recent paper in Ophthalmology describes UWFAF imaging evaluations of patients with AMD (n=200) and no disease (n=19). The authors report that overall, 69% of eyes had peripheral AF abnormalities (86% with neovascular AMD, 73% with non-neovascular AMD, and 18% in eyes without AMD) and identify a strong correlation between observed AF patterns and the clinical features of the disease. They propose a classification system for AMD based on distinct AF patterns in the periphery and suggest that these patterns may be predictive of disease progression. The Optos 200Tx utilized in the study is the only imaging system available with the capability for UWFAF.

Identifying Your Practice’s Target Patient Demographics

Posted on Saturday, June 22, 2013

Have you ever noticed that patients sometimes apply a “shopping” strategy to the process of choosing an eyecare practitioner? As odd as it sounds, a survey performed for the Vistakon Division of Johnson & Johnson Vision Care, Inc. revealed that “Patients choose your practice or reject it, based on how well the value proposition you offer aligns with their own shopping philosophies,” (Optometric Management).

The survey queried 7,500 visioncare consumers who ranged in age from 18 to 60. Participants were asked to answer 624 questions related to the factors that play into decisions regarding the purchase of glasses or contacts. As the results were tallied, five specific visioncare shopper segments were identified, which are:

 

Discriminating Health Investors: 19 percent of participants were identified as “discriminating health investors,” or shoppers who want only the very best and are able to pay for it. High-quality products and advanced technology, as well as building a trusted relationship with their practitioner, are of extreme importance.

 

Skilled Shoppers: Skilled shoppers accounted for another 19 percent of the population of survey participants. These visioncare shoppers seek quality products, care, and service, but also “want to feel like they are getting a good deal.”

Digital Communication a “Key” to Practice Growth

Posted on Thursday, June 20, 2013

Good digital communication with patients is key to growing an eyecare practice, according to a recent piece featured on the website of the Review of Optometric Business.

 

Tommy Lim, OD, of Berryessa Optometry in San Jose, California, asserted that professionals must connect with patients on a new level, using the technology patients already use to stay connected with the world. This “is critical to the survival and growth of a practice,” Lim said. It’s all about embracing today’s digital technology and using it to communicate in a manner that is most consumer-friendly.

 

In addition to using digital technology to communicate with patients, Dr. Lim shared the importance of establishing a strong, positive presence on the internet to reach potential patients. Vibrant websites can immediately grasp one’s attention, and positive reviews on sites like Yelp and other feedback-driven sites allow potential patients to research your practice.

 

And the technology you use within your practice can also enhance digital communication with patients, as well as attract new patients. Take Optos’ optomap technology, for example. One of the many benefits practitioners find with our technology is the ability to send patients an email containing their retinal images captured during an exam. …

Evaluating retinal ischemia in recalcitrant DME with Optos UWF fluorescein angiography

Posted on Monday, June 17, 2013

Visualizing areas of retinal non-perfusion in patients with recalcitrant diabetic macular edema (DME) can provide important insights about the disease process and management. Results published in the American Journal of Ophthalmology suggest that utilizing ultra-widefield fluorescein angiography (UWFFA) to evaluate retinal vascular non-perfusion using the established ischemic index can identify DME that will be most unresponsive to therapy. This link between the extent of untreated retinal ischemia and the degree of recalcitrance provides further evidence that areas of non-perfusion produce biochemical mediators of disease progression, such as VEGF. The authors suggest that UWFFA could be useful in selecting patients for targeted retinal photocoagulation of untreated areas of non-perfusion and that employing the ischemic index could also help determine frequency of anti-VEGF therapy.

Does Awareness Lead to Action Among Diabetic Patients?

Posted on Friday, June 14, 2013

The American Diabetes Association recently revealed the results of The Diabetes Eye Health Study, and they were quite interesting. Of those surveyed, 96 percent acknowledge that diabetes could lead to blindness, and 83 percent believe in the importance of annual eye exams. However, 20 percent admitted that they have not had an eye exam in the past year. As Health Canal puts it, the study unfortunately demonstrated that “awareness does not always drive action when it comes to eye health.”

 

The World Health Organization estimates that 347 million people around the world have diabetes, with about 25.8 million of those patients residing in the United States (Centers for Disease Control). John E. Anderson, MD, told Health Canal that it is absolutely necessary for these patients to have annual eye exams so they can avoid complications and decrease their risk of eye problems associated with diabetes such as glaucoma, cataracts, and diabetic macular edema, emphasizing that “diabetes is the leading cause of blindness in adults.”

 

If you haven’t been encouraging diabetic patients to continue with their annual eye exams, now’s the time to do so. It’s extremely important to remind them that this is not only the best way …

Interesting Facts About Sunlight & Kids’ Vision

Posted on Wednesday, June 12, 2013

There are several risks associated with too much exposure to sunlight, the most common being sunburn and premature aging of the skin. However, there are also some positive benefits that come with a “sensible” amount of sun exposure, including an improvement in sleep, a happier outlook, and protection from certain autoimmune diseases (U.S. News Health). And now, the results of two recent studies have revealed that spending time in the sun can be helpful in minimizing or preventing nearsightedness in children.

 

As Medical News Today shared in a recent article, one of the studies observed children in two elementary schools in Taiwan over the 2009-2010 school year. The children had previously spent their recess time indoors. But for the study, one school had its children spend a total of 80 minutes playing outdoors each day. The results of the eye exams that were conducted at the beginning and end of the study showed that significantly fewer children encountered nearsightedness in the school that required outdoor recess.

 

The leader of the study, Pei-Chang Wu, M.D., PhD., shared that since children spend so much time in school, “a school-based intervention is a direct and practical way to tackle the increasing …

How Color Can Impact a Medical Office

Posted on Thursday, May 30, 2013

In the past we’ve discussed some of the psychological effects color can have on a person, but when it comes to choosing the colors to use within the office of your medical practice, color psychology is not the only thing you want to take into consideration. You must also think about how the color will make a certain room look and feel when making your selections.

 

As a great article on color psychology and interior design that we recently came across notes, the wrong color can make an exam room unappealing to a patient. For instance, while white presents a crisp, clean look, some patients see it as sterile and uninviting. Reds and oranges are also sometimes seen as unappealing simply because they are so bold and assertive. And if an exam room doesn’t appeal to a patient aesthetically, they might not feel as comfortable and are less likely to have a pleasant visit.

 

These design experts also discuss the importance of selecting the right color combinations for exam rooms, calling it a “quintessential part” of the design process. For example, a room filled with lighter colors can make the room appear larger because the colors usually “fade …

Study Offers Insight to “Economic Burden” of Vision Loss in America

Posted on Tuesday, May 28, 2013

Recent years have brought about increasing healthcare costs, especially in America. Obesity and chronic illnesses are just a few of the contributing factors, but what do the roles of vision loss and eye disorders play in healthcare costs?

 

 

A new study recently published in Ophthalmology offers insight into just how costly vision loss and eye disorders are, particularly for the American population under the age of 40. According to the study, “the economic burden” of vision loss and eye disorders was $27.5 billion last year, with $5.9 billion in costs for children and $21.6 billion accounting for adults ages 18 to 39.

 

The study, which defines the numbers as “a substantial burden” for a group previously left out of similar studies, also broke the costs down by direct and indirect costs. Direct costs included $7.3 billion for medical costs associated with diagnosed disorders, $4.9 billion attributed to refraction correction, and $0.5 billion accounted for undiagnosed vision loss. Additionally, $1.8 billion were spent on other direct costs. Indirect costs accounted for $13 billion spent. Prevent Blindness America plans to present a more in-depth discussion on the economic burden of vision loss and eye disorders for …

Helping Patients Cope with Spring Eye Allergies

Posted on Thursday, May 23, 2013

Itchy, watery, red and swollen eyes accompanied with sneezing, coughing, and running noses can only mean one thing… spring allergy season is here. This year’s spring allergy season got off to an early start, and as WebMD shared earlier in the season, some doctors are seeing signs that allergy season “may be more miserable than usual this year.”

 

What’s the reason for this prediction? A false spring is partially to blame because it caused pollen levels to climb, dip, and then rise again. Stanley M. Fineman, MD, former president of the American College of Allergy, Asthma and Immunology who now practices in Atlanta, shares that the pollen pattern causes people who suffer with allergies to feel a “priming effect.” This is when patients are initially exposed to the allergens and then re-exposed after the dip and subsequential increase in pollen levels, causing patients to feel the effects even more because their bodies prepare to respond.

 

Allergies can make your patients feel horrible, especially when they feel the need to constantly rub their eyes or wipe tears away. However, there are a few ways you can help them combat the symptoms so they can enjoy the …
