optomap Enables Detection, Diagnosis, and Guides Treatment in Age-Related Ocular Pathology

September is Healthy Aging month, however despite age related changes to vision, ocular health is often overlooked.  As the aging population grows, adding the first influx of generation X to the baby boomers in the over 50 demographics, the incidences of glaucoma and Age-related Macular Degeneration (AMD) are also on the rise.

Recent studies have demonstrated how optomap ultra-widefield™ (UWF) retinal imaging is fulfilling a need in supporting the detection and management of both ocular and systemic diseases associated with aging. UWF imaging provides a high resolution, single-capture image of 82% (or 200 degrees) of the retina.  Studies have confirmed that the resolution of the optomap image – is comparable to fundus photography – which captures 11% of the retina, in detection of diseases such as diabetic retinopathy, AMD and uveitis.  Additionally, studies have found that the additional area captured by optomap can enhance the ability to detect, diagnose and manage diseases in comparison to fundus photography and be captured more efficiently.  UWF is being increasingly used in optometric and ophthalmic settings and enables eye care professionals to detect, diagnose, document and treat ocular pathology including retinal disease that may first present in the periphery.

Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in adults over age 50. The Centers for Disease Control and Prevention estimate that by the year 2020, 196 million people worldwide will be living with some form of AMD.

Although there have been many discoveries in the understanding of the causes of AMD, including links to genetics, there remains much unknown about this complicated, degenerative disease. Over time the retinal periphery has been able to be more easily studied in early AMD to determine the value in the detection and/or monitoring of the disease.  However, with the advent of multi-modality UWF imaging, novel studies are beginning to demonstrate this value. Color optomap imaging captures the structure and fundus autofluorescence (FAF) the function of the Retinal Pigment Epithelium (RPE) which is where AMD manifests within the eye. Studies have revealed that 97% of patients with AMD have evidence of the disease in the far periphery.

This outcome demonstrated that drusen were seen in a majority of eyes, strongly indicating that AMD is more than a macular condition but one that involves the entire retina. This is being investigated in a further study that will determine whether these peripheral changes are associated with the progression of the disease.   Read the Full Article

Glaucoma is another primary cause of blindness worldwide, affecting an estimated 70 million people. While early detection is key to taking steps to prevent vision loss, glaucomatous vision impairment is irreversible.  Unfortunately, glaucoma can be asymptomatic until the late stages, at which time the prognosis is poor.

The gold standard for detection and diagnosis of glaucoma is a clinical examination with dilated slit lamp biomicroscopy conducted by a glaucoma specialist.  However, this level of expertise is not always feasible or readily available to broadly evaluate an aging population. Exam efficiency has been increasingly addressed via use of color digital stereoscopic photography and/or retinal tomography via SD-OCT.

A recent  study explored the potential suitability of ultra-widefield retinal imaging in diagnosing glaucoma in situations where slit-lamp biomicroscopy or digital color stereoscopy are not available. The purpose of the study was to evaluate the reproducibility and validity of UWF in estimating Vertical Cup to Disc Ratio (VCDR) measurements and was the first study of its kind to explore whether optomap imaging could be suitable as a diagnostic support tool for glaucoma.

The study evaluated the data from color digital stereoscopic fundus images (CDS) and UWF images.  All the photographs and images were graded by two masked trained graders and one masked glaucoma specialist. The optomap images were graded using the ‘measure distance’ tool on the OptosAdvancesoftware, to measure and record cup to disc ratio (CDR).

The study demonstrated an almost perfect agreement between CDS and optomap when assessed by the glaucoma specialist.   The study concludes that optomap imaging has a high reproducibility in evaluating VCDR and agreement with stereoscopic optic disc imaging and indicates that UWF imaging may be suitable for glaucoma evaluation in settings where CDS is not available.

optomap Image is a Savior to Teen’s Vision

With August deemed Children’s Eye Health and Safety Month, there cannot be enough stress placed on the importance of protecting children (including teenagers) eye health.  Healthy eyes and good vision are essential for the physical and educational development of children. Most children have healthy eyes. However, vision problems can begin at an early age and go unnoticed by both children and their parents. Early detection and treatment are indispensable in preventing conditions that could potentially cause problems or permanent vision loss.

Christina, a high school student in Manhattan Beach, California walked into her eye doctor’s office thinking it was just going to be another eye appointment and yet another glasses fitting.  Dr. Dale Choi, of Manhattan Beach Vision Group, recommended Christina get an optomap image as part of her exam that day.  To their surprise, the image revealed a significant finding.  Dr. Choi discovered a retinal hole with a large sub-clinical detachment in her left eye.  Dr. Choi reviewed the image with Christina, explaining that she would need to be referred a retina specialist that same day, to repair the hole and save her sight. Fortunately for Christina, the local specialist was able to repair the hole with no damage to her vision.

According to Dr. Choi, optomap has diagnosed many systemic conditions that otherwise would have gone unknown and often gotten worse.  Without it the optomap, Christina is unsure how she would have known about the detached retina before it was too late.  “It gives them peace of mind. It gives them ultimately the care that should be standard in all eye exams,“ says Dr. Choi.

Optos is committed to educating parents on the importance of having their children’s eyes checked regularly. Protect your children’s eye health by making an optomap part of their yearly comprehensive eye exam.  Visit our website for more sight-saving stories like Christina’s and find an optomap provider near you to schedule your child’s eye exam today!

Back to School Means More Than Backpacks and Lunch Boxes – Don’t Forget the Eye Exam!

While to some it may feel as though summer has just begun, others are already feeling the pressures of checking off every item on their back to school lists.  With all the hassle of stocking up on school supplies or finding the perfect pair of shoes, there is often one important item that gets left off every parent’s list – a comprehensive eye exam.  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 done so visually, therefore without excellent vision, children are left at a disadvantage.  Those with poor eyesight may struggle with school and learning, leaving them unable to reach their maximum potential.  A yearly comprehensive eye exam can not only ensure your child’s vision is healthy or corrected, but also rule out diseases that can potentially lead to vision loss.

Just as their bodies are rapidly growing, children’s eye are also changing. The slightest change in vision can cause eye strain, headaches or blurred vision which can be very distracting in school.  Myopia and hyperopia, also known as near or farsightedness, are both common conditions in young children, with the ability to worsen rapidly during the growing years until later stabilizing in teenage years and into their early twenties.

Additionally, with recent increases in digital technology, both at home and in schools, it is important to monitor the face time children and teens have with their digital devices such as laptops, tablets and cell phones.  Many individuals suffer from physical eye discomfort after screen use for more than two hours, reflecting collective symptoms know as digital eye strain.  According to The Vision Council, 72 percent of Americans report their children and teens get more than two hours of screen time per day while 30 percent of this group report they experience at least one of the following symptoms after being exposed for more than two hours:

  • Headaches
  • Neck/shoulder pain
  • Eye strain, dry or irritated eyes
  • Reduced attention span
  • Poor behavior
  • Irritability

With a growing number of schools implementing iPads, tablets or laptops in the classroom, it is even more important to ensure your children’s eye health with routine comprehensive eye exams and identifying any symptoms of digital eye strain in addition to any headaches, eye strain or blurred vision.

Adding comprehensive eye exams to your yearly back to school routines will help ensure a successful school year as well as protect your children’s eye health and future.  Speak to your doctor about including optomap® as part of the exam – it is a non-invasive option for your child and takes only seconds to get a highly-detailed view of the retina, which is critical for early disease detection.

optomap Screening Reveals Cataract in Unsuspecting Doctor

While the exact causes of cataracts are still not entirely understood, annual eye exams are still important for the diagnoses and treatment of their formation.  Even with precautions and regular exams, by the year 2020, more than 30 million Americans are expected to develop cataracts.

Most cataracts occur gradually as we age and don’t become bothersome until after age 55. However, cataracts can also be present at birth (congenital cataracts) or occur at any age as the result of an injury to the eye (traumatic cataracts). Cataracts can also be caused by diseases such as diabetes or can occur as the result of long-term use of certain medications.  While typically forming in both eyes, cataracts may not grow at the same rate. They can develop slowly or quickly, or progress to a certain point, then not get any worse. As a result, one may not notice substantial changes in their sight. Sometimes they can significantly precede symptoms and can be so subtle as to go unnoticed without a comprehensive eye exam.

Read Dr. Young’s full testimonial by clicking on the image above.

When Vince Young, OD introduced Daytona, into his practice, he volunteered to be the imaging guinea pig while his staff trained on the device.  He was unnerved when he reviewed his images and somewhat uncertain about what he was seeing.  He knew what a posterior subcapsular cataract (PSC) looked like through the slit lamp but was surprised by what the optomap image revealed. Concerned, Young sent the image to his wife, Lindsey Brewer Young, OD. When she reviewed the image on her phone she immediately responded, questioning whose eye she was reviewing.  Learning it was her husband’s image she returned to the clinic, conducted a dilated exam, and confirmed that it was indeed a PSC that had been revealed in the optomap image.

At 40 years old, Dr. Young had no reason to suspect he would have cataracts as they are more typically associated with the elderly population. He also exhibited no symptoms or clouded vision.  A subcapsular cataract occurs at the back of the lens and can be caused by a variety of circumstances such as systemic issues and some forms of medication. PSCs are also more difficult to remove due to adhesion of the cataract to the lens capsule as well as an increased risk of capsule rupture during removal. However, Young’s cataract surgery on both eyes was successful and today his vision is fine.

Young reports that while this initial training episode was distressing, the image itself has become an excellent tool in communicating the importance of optomap and comprehensive exams to his patients.  The image hangs in the exam room and Young and his staff frequently share the story. “If the doctor didn’t know he had a cataract, how would anyone else know?” they say, underscoring the value of retinal screening. The unusual story has assisted with the elevated level of acceptance the optomap imaging has had in Young’s office.

Young stresses that the exam experience has changed with optomap in an extremely valuable way when it comes to patient education. optomap enables him to help his patients understand exactly what is occurring in their eye, or even just to provide reassurance that all is well. “Even if there is no pathology, patients want me to take the images every year. They want to see what I see.”

Dr. Young’s story demonstrates that it is not only possible for practitioners to image themselves and discover retinal pathology but also discover if significant opacities reside in the media as well.  The importance of regular, annual comprehensive eye exams cannot be expressed enough in the discussion of eye and systemic health.

May is UV Awareness Month – Be Wise and Protect Your Eyes!

As summer draws near, most of us long for the glorious warmth of the sun and we dream about, and plan for, the recreation we will enjoy. Unfortunately, while awareness of the importance of sunscreen and UV protective clothing has increased, the impacts of all that fun-in-the-sun on the eyes is still often overlooked.  Most people do not realize that 20% of all cataracts are the result of UV ray exposure, and that number has been dramatically increasing in recent years.

But what is this invisible threat exactly?  And how does it impact us? Ultraviolet radiation is measured in nanometers (nm). It is categorized in three basic terms and classified by the strength of the UV ray:

  • 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 leading to damage of the retina. They contribute to the occurrence of cataracts, are also a major cause of aging and unfortunately can pass through clouds, glass, water and clothing.

But what about Vitamin D?  A little sun exposure is healthy for us, right?  Vitamin D is essential to help your body absorb calcium and promote bone growth. Vitamin D is also beneficial for other important body functions and it has been shown to be essential to a healthy immune system.  However, just 5-15 minutes in the sun is enough to help stimulate the production of Vitamin D.

Prolonged UV exposure has numerous immediate and deleterious negative impacts. Many skin cancers can occur on the eyelids and external features of the eye.  Additionally, while ocular melanoma is rare it is the most common eye cancer in adults. Because of the increasing number of UV related cataracts and eye cancers; Prevent Blindness, and many other organizations, strongly recommend that everyone utilize UV Protection eyewear, not only those who engage in outdoor disciplines and recreation. It is recommended that sunglasses and UV treated daily wear should be 100% UV absorbing for UVA and UVB light.

When we are caught up in the delightful pursuits of summer – particularly exuberant children – we tend to overlook the simple proactive measures that we can take to protect against vision loss and UV related eye damage and even life threatening ocular cancers.  In addition to taking a few extra moments to protect yourself and your loved ones before rushing out into the sunshine, it is imperative that people take the time for annual eye exams. An optomap screening is an excellent, expedient way to get a comprehensive view of the retina and to gain essential information about ones ocular health. optomap is the only proven, clinically-validated, ultra-widefield retinal image that can capture 82% or 200⁰ of the retina, which can reveal incredibly subtle changes from the central pole to the far periphery of the retina in a single capture – and in a fraction of a second – so you can get out there (well-protected, of course) and enjoy that summer sun.
