VIEWS Joanne Marchitelli It’s been an exciting past year for space discovery. It seemed you couldn’t escape an aeronautical news story— from the February 2018 launch of the Tesla Roadster hitching a ride on SpaceX’s Falcon Heavy rocket to China’s robotic Chang’e 4 mission landing on the far side of the moon in January 2019, and sadly, to NASA declaring Opportunity rover dead after a remarkable 15 years exploring Mars. Besides exploring unknown worlds beyond Earth, space exploration also helps us understand our own. Take for example, the current mission involving optical coherence tomography (OCT) technology. In May 2018, NASA launched Heidelberg Engineering’s SPECTRALIS with the OCT2 Module to the International Space Station (ISS). Its flight aboard the Antares 230 Cygnus CRS OA-9 departed from Wallops Island, VA, and the imaging platform was placed into service in December. The instrument replaced the SPECTRALIS OCT that has been in operation at the ISS since 2013. The purpose of the OCT’s mission is to better understand Space Flight Associated Neuro-Ocular Syndrome (SANS). By imaging the choroid and optic nerve of astronauts during flight and upon return to Earth’s gravity, it will help researchers counter the effects of SANS in future, farther, space travel. According to NASA, the use of the OCT device will monitor the changes to crew members’ eyes during the mission and

provide real-time medical evaluations to physicians on the ground. The use of OCT technology will also improve data gathering for investigations studying visual impairment and intracranial pressure in space. Ongoing research through NASA’s Vision Impairment and Intracranial Pressure (VIIP) project has been studying the effects of long-term exposure to microgravity on the structure of the eye. Dilated fundus examinations with binocular ophthalmoscopy, cycloplegic refraction, OCT, magnetic resonance imaging (MRI) of orbits, and fundus photography for before and after space missions are just several ophthalmic procedures performed on astronauts. In one VIIP study, 27 astronauts underwent thin-section, 3D, eye orbital, and conventional MRI brain scans. Eight astronauts underwent repeat imaging after an additional mission in space. All astronauts had previous exposure to microgravity. Image analysis of the optic nerve sheath, optic disc, posterior globe, and pituitary gland was performed and compared for association with intracranial evidence of excessive fluid buildup inside the skull, cells, tissues, or body cavities, venous blood clotting in the brain and/or mass lesion. MRI findings suggest that intracranial hypertension is an important component to visual acuity degradation, but since not all astronauts show visual acuity degradation, existing risk factors could be to blame. By using OCT imaging they hope to better understand the cause-and-effect relationship of intracranial pressure after exposure to microgravity and who may be at risk. Back on earth, OCT is used to diagnosis and monitor the progression of diseases such as diabetic retinopathy, retinal vascular disease, vein occlusion, artery occlusion, macular degeneration and glaucoma. In this issue, we explore how glaucoma can be monitored with OCT angiography—a feature that is on the OCT2 Module—to get a better understanding of disease progression. The latest frontier of this technology is sure to push the boundaries of treatment. *** Joanne Marchitelli | Editor | JMarchitelli@FVMG.com

continue that tradition. I want to build solutions that our customers view as valuable. I want to evolve in ways that will really benefit our customers either through revenue growth, expense efficiencies or through better service to their patients. JM: How do you see ABB helping the independent eyecare professional grow? TB: For us, being able to give doctors unique solutions to continue to care for their patients is where we fit in. One example is that we’re not just in the contact-lens distribution business. We also have optical labs nationwide and we are in the frames distribution business. We also provide data and analytics around best-in-class service to eyecare practices. And we’re going to continue to evolve in even more solutions as we go forward. JM: Where is ABB going from here?

ONE-TO-ONE Thomas E. Burke, III Chief Executive Officer, ABB Optical Group

Prior to joining ABB Optical Group in August 2018, Thomas Burke served as CEO of Medical Specialties Distributors; senior vice president/general manager of Innovative Delivery Solutions for Cardinal Health; and CEO and president of Novis Pharmaceuticals. He has nearly four decades of experience in the distribution and healthcare industry with extensive experience in sales management, operations and employee development. Joanne Marchitelli: What is your general vision for ABB? Thomas Burke: We’ve got an amazing business that is essential to the distribution platform, specifically on the contact-lens side of the optical world. The reason we are who we are is because Angel Alvarez and others deeply cared about our customers and our vendor relationships, and made decisions based on what’s good for the doctor and the community. Supporting the doctor differentiates us, and we will 4 M a r ch 2 01 9 | O p to m e tri c O f f i c e .c o m

TB: We are focused on six priorities, and all of them are equally important and critical to our success and the success of our customers. One priority is to take a good, hard look at the role we play with information and how we can provide information to our partners as well as to doctors in the field that can help them be more productive. Another priority is to continue to build out solutions that can help the doctor either grow, manage their expenses in their practice, or become better service providers. Another absolute priority for us is to continue building meaningful relationships that are founded on trust. That’s with our customers, our vendors and our employees. I don’t want to be everything to everybody. I don’t believe in that. I believe in being everything to the people we partner with in a very transparent way. Next is eyewear. We’re making a major investment in a new lab in the Midwest this year. We are continuing moving forward with the frames distribution piece of this business. We’ve got an amazing lab to begin with. Eyewear is absolutely a priority for us. Also a priority for us is network optimization. We recognize that we have to get it right. We want to get it right. Our customers depend on us to correctly pick, pack and ship the right products at the right price and at the right time. We will continue to evolve, innovate and test our network strategies to make the process as efficient as possible so fill rates are up, errors are down, and our customers’ costs remain low. Then the last one, which certainly is not last in terms of importance, is growth; but I don’t want to think about it in terms of ABB growth. I prefer to think about the growth of a practitioner because that’s what matters. Their earnings are what matters. To help them grow their top line and continue to serve their patients, we must have the right solutions for them to do that. ***

THINK ABOUT YOUR EYES

DEMYSTIFYING

ALLERGIES Blurry vision, red eyes, contact lens irritation… A patient could blame an old prescription or needing to try a new type of contact lens. However, all of these symptoms could be caused by allergies. While a runny nose and sneezing are the stereotypical allergy symptoms, allergies can also cause a host of vision and eye symptoms that we as optometrists need to be aware of when it comes to treating patients. MEDICATION RECOMMENDATIONS When it comes to the treatment of allergies and accompanying vision issues, there are several routes one can take. A medication anti-allergy eye drop may be recommended or prescribed, such as over-the-counter antihistamine eye drops that can provide relief. Most of these have twice per day dosage. A prescription anti-allergy drop can also be prescribed for those who do not respond well to the overthe-counter medications. Some prescription medications can also be used in prevention of symptoms for those who experience seasonal allergies every year. However, timing is crucial. If someone typically experiences allergy symptoms starting in March, they could be well served by starting treatment in February.

LIFESTYLE MODIFICATIONS Home remedies and lifestyle modifications may benefit patients with any severity of symptoms. These can include limiting exposure to allergens (i.e., staying indoors when pollen levels are high, or avoiding travel to locations with high levels of allergen). Practicing good hygiene and cleanliness can also vastly help alleviate systems. Frequent washing of hair, clothes, towels or bedding that may have

been exposed to an allergen can keep allergens and pollen from getting “trapped” and building up, leading to continuous exposure. I also counsel patients to manage systemic allergy symptoms. Those with more significant sinus issues due to allergies also tend to have more significant eye and vision symptoms. Managing the sinus congestion can also minimize eye symptoms. It doesn’t always seem like a natural inquiry when visiting with a patient, but ensuring we have a complete picture of their health will only benefit us as advocates of their vision health. This makes the annual eye exam a crucial check-in with the patient. The Think About Your Eyes campaign continuously reminds patients to schedule an annual eye exam, which will allow us to continue to assist in other health issues that may be impacting their vision health.

INSTRUMENTS

OCT - A The latest advance in OCT technology helps manage patients with glaucoma.

A vessel density map of the patient’s right optic nerve head on the Optovue Avanti (left). The dark navy wedge on the bottom of the scan correlates with the wedge defect seen on the fundus image (right). The vessel density map allows for quantification of the non-perfusion in this area due to glaucomatous optic neuropathy.

B y J o anne Marc hitelli OCT in the optometric practice has been steadily gaining ground in recent years. The gold standard for glaucoma management has been, and still is, optic nerve head assessment and visual field perimetry, but here comes OCT-A technology to up the ante. “For the first time we’re able to quantify blood vessel density which we haven’t been able to do. We’ve been able to look on a structural level, but we haven’t been able to look at what’s actually happening at a microvascular level,” said Julie Rodman, OD, MS, FAAO, associate professor, Nova Southeastern University, Fort Lauderdale, FL. “This has been really helpful to identify disease a lot earlier than we have been able to before. It’s a non-invasive way to view retinal vasculature and see where the damage has occurred, not just confirm that it occurred.”

THE DIFFERENCE BETWEEN OCT AND OCT-A OCT evaluates the structure of the retina—it provides an in-vivo analysis of both the retinal and choroidal anatomy, she explained. “OCT-A was created not to take the place of OCT but to provide a different dimension,” said Rodman. “OCT-A 8 M a r ch 2 01 9 | O p to m e tri c O f f i c e .c o m

provides visualization of the peripapillary capillaries and correlates more strongly with a patient’s visual function by providing a functional analysis. Reduced peripapillary perfusion correlates with focal defects on visual field, RNFL and GCC thickness. Using them together, we get a structural and functional analysis side by side.”

WHAT IT MEANS FOR PATIENTS WITH GLAUCOMA “With regards to management of glaucoma, OCT-A opens the door for personalized glaucoma care,” said Carolyn Majcher, OD, FAAO, chief of the Retina Clinic and assistant clinical professor, University of the Incarnate Word Rosenberg School of Optometry in San Antonio, TX. While it’s been known for some time that vascular dysregulation contributes to the pathology of this multifactorial disease, for some eyes this may be more of a leading player than others. “When I see a glaucoma patient with substantial perfusion compromise as visualized with OCT-A, I am more inclined to

select a vasoactive agent such as dorzolamide,” said Majcher. “Similar to pattern ERG testing in glaucoma, perfusion compromise is at least initially a reversible thing. So it may prove to be useful in providing feedback to the clinician as to whether adequate treatment has been achieved.” In the future, she believes that doctors may be titrating treatment to achieve “perfusion targets” rather than target IOP levels alone.

BENEFITS OF OCT-A “The literature that I’ve read and the experience that I’ve had is that OCT-A is very good at identifying early damage in primary open angle glaucoma (POAG); earlier than we would see with visual field or other modalities,” said Rodman. “The reason is that primary open glaucoma results from both mechanical factors and vascular dysregulation, and a vascular problem is going to be picked up on a vessel density analysis provided by OCT-A analytics.” In angle closure glaucoma, the elevated intraocular pressure affects the

RNFL measurements before affecting the vascular density; thus OCT-A may be a more desirable objective screening tool for POAG.

OCT-A TECHNOLOGY Optovue’s Avanti AngioVue system is available in three configurations: AngioVue Comprehensive, AngioVue Essential and AngioVue Retina. The latter two can be upgraded to the Comprehensive system. “AngioVue Essential provides streamlined OCT-A image interpretation in a single page report allowing for an efficient way to evaluate and manage retinal disease that may necessitate a referral.” Its highresolution, non-invasive imaging of retinal vasculature helps visualize ocular disease. The single-page report displays individual layers of retinal vasculature alongside structural OCT B-scans. With AngioAnalytics, doctors can measure foveal avascular zone parameters, areas of abnormal flow in the outer retina and choroid, and vessel density. Its multi-scan analysis allows for assessment of progression at each patient visit and trend reports help predict change over time. In addition, Optovue’s 3D projection artifact removal (3D PAR) software removes shadows from the vessels to improve image quality. Carl Zeiss Meditec, Inc. offers ZEISS AngioPlex on its CIRRUS HD-OCT. “AngioPlex OCTA imaging is able to noninvasively detect and highlight reduced perfusion and capillary vessel density loss in glaucomatous eyes within both the peripapillary and macular regions,” said Majcher. “It is therefore another tool in my ‘glaucoma tool belt’ along with other objective measures such

as retinal nerve fiber layer (RNFL)/ganglion cell complex thickness that aids in glaucoma diagnosis and detection of glaucomatous progression.” New software versions are expected to include a 4.5 x 4.5mm optic nerve head OCT-A scan that automatically visualizes the radial peripapillary capillary network that is affected in glaucomatous eyes.

Heidelberg Engineering recently received clearance from the U.S. Food and Drug Administration for its OCT Angiography Module. The OCT Angiography Module can be added to new and existing upgradeable SPECTRALIS devices with the OCT2 Module. The upgrade delivers a lateral resolution of 5.7 μm/pixel. In addition, the module and the device’s TruTrack Active Eye Tracking allows the fine capillary networks to be visualized in great detail and its PAR tool utilizes information from the superficial vascular plexus to remove artifacts from OCT-A images and enables a more precise visualization of vascular structure and pathology. While Topcon Medical’s OCT-A technology is not available on its instruments in the United States, the swept source technology in its DRI OCT Triton is still a valuable tool in a glaucoma diagnosis and management. “With the Triton SS-OCT, I can see the vitreous, I can image the retina, I can image the choroid,” said Victor Gonzalez, MD, founder of the Gulf Coast Eye Institute in the Rio Grande Valley in Texas. “This is so important in helping me decide how my treatment moves forward, or

how I need to alter that treatment.” In addition, its en face technology allows visualization of various layers of the retina.

WHAT ARE YOU WAITING FOR? “Every optometric practice right now should hopefully have an OCT,” said Rodman. “I think in the next decade, every machine will have OCT-A on it, but for now, unfortunately, it’s still a novelty for a lot of folks.” But she assures that once novice users experience the technology and learn it, it will become not only easier to use but an essential part of the glaucoma practice.

PHARMACEUTICALS

SOLUTIONS FOR OCULAR ALLERGY SYMPTOMS How to successfully identify and treat in clinical practice. B y MILE BR UJ IC , OD , FAAO Oftentimes we are presented with the acute symptomatic patient who comes in complaining about red, itchy, irritated eyes. It is incumbent to accurately identify ocular allergies and differentiate them from other conditions that may present similarly, such as dry eye, blepharitis, viral conjunctivitis, bacterial conjunctivitis and infiltrative keratitis. There are several factors that can help identify allergic conjunctivitis from these other entities. Frequently, the presentation is an acute onset and symptoms are associated with seasonal changes and the presence of allergens in the environment. This is not an absolute rule as some individuals may have chronic ocular allergies that are present year-round and the symptoms simply spike with seasonal changes. The most common accompanying symptom that these patients will have is itching. With acute allergic conjunctivitis, this symptom may be more prevalent in the inner canthal 10 M a r ch 2 01 9 | O p to m e tri c O f f i c e .c o m

region. This occurs because the natural blink mechanism moves the tears to the inner canthal region where they drain through the puncta on the superior and inferior eyelid. This can cause accumulation of allergens and histamine. Histamine causes much of the signs and symptoms associated with allergic conjunctivitis. Other signs that accompany allergic conjunctivitis include conjunctival hyperemia, conjunctival swelling, eyelid swelling and epiphora. Just as important as identifying the acute presentation of allergic conjunctivitis is identifying those individuals who may have allergic presentation outside of the time of their eye exam. As an example, if you see a patient during the winter months for their exam, it is important to question them about ocular symptoms that they may have or medications that they may take at other times of the year. Patients with seasonal allergic conjunctivitis may not think to make us aware of ocular symptoms that are

not present at the time of their visit. Identifying patients that may take oral antihistamines at other times of the year is critical in order to determine the presence of ocular symptoms. If they do have ocular symptoms itâ&#x20AC;&#x2122;s incumbent upon us to offer appropriate treatment options for when their symptoms manifest.

PREVENTION For the contact lens wearer, oftentimes the best solution is to make sure that the patient is wearing daily disposable lenses. Since they are disposed of on a daily basis, any allergens that have accumulated on the lens during the day are disposed of. When a new lens is placed on the eye each day it minimizes the chances of the lens causing additional ocular comfort issues and can help reduce symptoms of allergic conjunctivitis. If a patientâ&#x20AC;&#x2122;s prescription is not available as a daily disposable lens, hydrogen peroxide cleaning systems, such as CLEAR CARE and CLEAR

â&#x20AC;&#x153;If you see a patient during the winter months for their exam, it is important to question them about ocular symptoms that they may have or medications that they may take at other times of the year.â&#x20AC;?

CARE PLUS (Alcon Laboratories), work remarkably well to sufficiently clean the lenses. These two peroxide systems are also approved for gas permeable (GP) lenses, so be sure to keep them in mind for those allergy sufferers wearing GP lenses. Patients can try removing themselves from the allergen or if that isnâ&#x20AC;&#x2122;t possible, removing the allergen from themselves. This is typically done with artificial tears but only usually provides temporary relief. Cold compresses help with inflammation of the lids but will not get to the root of the problem which is histamine being released from mast cells. Mast cells release histamine when allergens bind to immunoglobulin E (IgE) receptors on the mast cells. This causes what is referred to as mast cell degranulation, releasing massive amounts of histamine, which causes itching, hyperemia and edema.

EYE DROPS Fortunately, several therapeutic options exist to help patients with seasonal allergies. There are several antihistamines that are available. Olopatadine, a mast cell stabilizer, is available in three concentrations from Novartis: 0.1% (Patanol), 0.2% (Pataday) and 0.7% (Pazeo). Patanol is approved as a twicea-day dosing regimen and Pataday and Pazeo as a once-a-day drop. Both 0.1% and 0.2% concentrations of olopatadine are available as generic drops. Lastacaft (Allergan) is 0.25% alcaftadine and is approved as a once-daily dosing regimen. Two other prescription options that are available are epinastine 0.05% (Elestat from Allergan) and azelastine 0.05% (available as a generic). These are both approved as a twice-a-day dosing regimen. There is also an over-the-counter option that is available for the treatment of allergic conjunctivitis. Ketotifen 0.025% is approved as a twice-a-day dosing

regimen and is available under several brands including SYSTANE Zaditor (Alcon), Alaway (Bausch + Lomb) and Equate Eye Allergy Relief Drops from Walmart. A new antihistamine drop will be available in the U.S. in 2019. It is Zerviate (Eyevance Pharmaceuticals), which is the first topical ocular formulation of cetirizine. It is formulated at a concentration of 0.24%. Cetirizine is an antihistamine that competitively binds to histamine receptors to reduce the signs and symptoms of allergic conjunctivitis. Cetirizine is currently commercially available as an oral medication, Zyrtec (Johnson & Johnson Consumer, Inc.).

CORTICOSTEROIDS There are times when a patient with active allergic conjunctivitis requires a topical corticosteroid to control the signs and symptoms initially and before managing with a topical antihistamine. Although you need to make sure that you are assessing the intraocular pressure when a topical corticosteroid is used, they are usually used for only a short period of time to sequester the inflammatory response caused by the allergen. There are several topical corticosteroids available. Loteprednol is available in two concentrations: 0.2% and 0.5%. The 0.2% is available as Alrex (Bausch + Lomb). Alrex is approved as a four-times-a-day dosing regimen for allergic conjunctivitis. The higher concentration of 0.5% is commercially available as loteprednol gel. Although not specifically approved for allergic conjunctivitis, many use it to sequester the initial symptoms of the disease. Fluoromethalone acetate 0.1% is a topical corticosteroid available as Flarex (Novartis). Although not specifically approved for allergic conjunctivitis, it is

approved for the treatment of steroid responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea and anterior segment of the eye. The acetate formulation has shown significant improvement in efficacy over the alcohol formulation of fluoromethalone. Managing allergic conjunctivitis is becoming an increasingly important component to our practices. Understanding appropriate identification and treatment strategies is critical to effectively managing these patients. A proactive approach is the best way to help these patients manage their symptoms. O|O

VITEYES RELEASES DIGITAL DEFENSE GUMMIES Harmful blue light has been attributed to many eye issues (light sensitivity, itchiness, redness, blurry vision, dry eyes) and contributes to headaches and sleep problems. The latest dietary supplement from Viteyes, Blue Light Defender, enables your patients to safeguard their eyes from harmful blue light, which is emitted everywhere from digital devices, computer monitors, television screens, and even sunlight, by helping to block the detrimental effects of these blue wavelengths. The all-natural gummies contain the antioxidant lutein to protect and maintain healthy cells within the eyes and absorb blue light to protect the eyes from damaging rays; the carotenoid zeaxanthin, which helps to maintain macular and retinal health, protecting the eyes from detrimental blue light as well; and bilberry fruit extract to improve blood flow and oxygen delivery in the eyes.
