Ep. 020: Medical Ministry International - Providing Eye Care in Developing Countries with Jim Caudill, MD and Steven Suh, MD
In this special 20th episode, Dr. Suh talks with Dr. Jim Caudill, an ophthalmologist from Charleston, West Virginia, about their work with Medical Ministry International (MMI), a Christian medical mission group whose volunteers participate in one- and two-week projects to developing nations. Several of the leading causes of visual impairment in the world are preventable or treatable. People with uncorrected refractive errors, which means they are nearsighted, farsighted, and/or have astigmatism, can see better with a pair of prescription glasses. But in many developing countries, prescription glasses are not easy to obtain. Cataract, a clouding of the natural lens, is responsible for about half of the world blindness, which represents about 20 million people. Lack of access to or lack of financial means for surgery as well as longer life expectancy are some of the factors that have led to this increasing number of untreated cataracts. In the developing world, being blind decreases one’s life expectancy by one-third. 50% report loss of social standing and decision-making authority. Children may be unable to attend school because they must care for their blind relatives. The annual worldwide productivity cost of blindness is estimated to be in the hundreds of billions of dollars. Many charitable medical organizations have been around for decades to do short-term trips in these developing countries to lessen the burden of their much-needed medical care. MMI has been around for over 50 years. They provide dental, medical, surgical, OB/GYN, eye care, and physical therapy services around the world with short-term missions and in their permanent centers.

Ep. 019: Dealing With Diabetic Retinopathy with Lisa Borkowski, MD
Diabetes mellitus can affect the eyes in multiple ways. Even early in the diagnosis, high blood sugar levels can cause changes in the natural lens of the eye that can alter one’s refractive error (glasses prescription). Diabetes can also lead to earlier cataract formation. On this episode of the Healthy Eyes 101 podcast, Dr. Lisa Borkowski, a specialist with Midwest Retina, talks about diabetic retinopathy, one of the leading causes of vision loss in the United States and worldwide. Symptoms of diabetic retinopathy (DR) include blurred/distorted vision, an increase in floaters, or dark areas in the field of vision. However, many patients do not have any visual symptoms at all. This is why diabetics should have their eyes checked on a regular basis. Those with type I diabetes should get their first exam within 5 years of diagnosis. Those with type II diabetes should be examined soon after diagnosis because many of these patients may have had uncontrolled sugar levels for years. The two main categories of diabetic retinopathy are non-proliferative (NPDR) and proliferative (PDR). When blood sugar levels remain elevated, NPDR can cause the retinal blood vessels to leak or even close off. If the leakage occurs near the center of the retina (macula), there can be vision loss. With PDR, the more advanced stage of DR, new blood vessels form (neovascularization) on the surface of the retina. These fragile vessels can bleed into the vitreous gel and block vision. To properly diagnose DR, a dilated examination or extensive retinal photographs need to be performed by your eye care specialist. Many retina surgeons will also perform a fluorescein angiogram so that they can see areas of retinal swelling (macular edema) and new blood vessel growth. OCT (ocular coherence tomography) is useful for following changes in macular edema. Treatments for DR include eye injections with ant-VEGF medications, laser surgery, and vitrectomy surgery in the operating room. What can patients do to decrease their risk of losing vision from DR? Control the blood sugar levels and blood pressure and see your eye care specialist at the recommended intervals. Here is another great resource on *diabetic retinopathy*.

Ep. 018: Is Laser Vision Correction Right For You? - with Curtin Kelley, MD
Refractive eye surgery involves changing the refractive state of the eye to decrease one’s dependency on glasses or contact lenses. The first corneal refractive surgical procedure developed was radial keratotomy (RK). Corneal instability and progressive shifting of the refraction (glasses prescription) made this surgery obsolete. LASIK (Laser-Assisted In-Situ Keratomileusis) and PRK (PhotoRefractive Keratectomy) use the excimer laser to reshape the cornea to help focus the light rays onto the retina like glasses or contact lenses do. These laser vision correction (LVC) procedures can correct nearsightedness, farsightedness, and astigmatism. Patients who may not be good candidates for LVC: * Thin corneas * High glasses prescriptions * Keratoconus * Autoimmune diseases like rheumatoid arthritis * Perfectionists * People who need excellent nighttime vision, like truck drivers or airline pilots * Currently on certain medications like Accutane/isotretinoin (or other acne medications) * Large pupils * History of past corneal infections * Unstable glasses prescription * Severe dry eyes Presbyopia (decreased ability to see up close) starts in the mid-40s. If both eyes are lasered to correct their distance, then they will need reading glasses. Monovision is an option where one eye is set for distance and the other eye is set for or left with some nearsightedness. Nowadays, both eyes are usually lasered in the same sitting. The first step in LASIK is to use a femtosecond laser or a micro-keratome blade to make the corneal flap. In PRK, the top layer of cells (epithelium) is carefully scraped off. The excimer laser energy is then applied to the exposed cornea to reshape it. This laser may take up to ~50 seconds per eye. If PRK was performed, then a bandage contact lens is placed to help the epithelium to grow back and for pain control. With LASIK the vision may be fairly sharp immediately after the procedure. PRK has a slower recovery because the epithelium has to grow back onto the cornea. The final results of the PRK may not be seen for several weeks. PRK may be chosen because of thin corneas and for people who are in a profession where eye injuries can occur. LASIK has become the more popular procedure because of its quicker recovery and less discomfort. Complications may include corneal infections, intra-flap inflammation (diffuse lamellar keratitis (DLK)) in LASIK, halos at night, and difficulty driving at night. Ectasia (progressive thinning and warpage of the cornea) may be difficult to treat and the patient may need to wear hard contact lenses to improve their vision. The ICL (Implantable Contact Lens) is a refractive intraocular lens that is placed into the area behind the iris and the natural lens. This can treat high amounts of nearsightedness and astigmatism without having to sacrifice any corneal tissue. The SMILE (SMall Incision Lenticule Extraction) procedure utilizes the femtosecond laser to create a disc of corneal tissue that is removed. This procedure, which can correct nearsightedness and astigmatism, has not been used in the United States as much as in Europe and other countries.

Ep. 017: Watery Eyes and Blocked Tear Ducts with Kenneth Cahill, MD
Oculoplastic specialist, Dr. Kenneth Cahill, joins Dr. Suh to discuss a bothersome condition – epiphora, the medical term for watering eyes. Why does excessive tearing occur and what we can do about it? Blocked tear ducts are a major cause of chronic watering. Causes of excessive watering * Overproduction of tears * Abnormalities of the eyelids (ectropion (outward turning of the lower lid), entropion (in-turning of the lower lid), or lid weakness) * Blockage of the tear drainage system (nasolacrimal duct) * Ocular surface irritation (dry eyes, foreign body, allergies) Tear glands on the upper part of the eyeball produce the tears. The tears will drain into the punctum, the tiny hole at the margin of each lid close to the nose. This opening leads to the canaliculus, the tube that connects the punctum to the lacrimal sac. From there the tears will end up in the nasal cavity. A blockage, temporary or permanent, can lead to excessive watering. Symptoms of a blocked tear duct * Tenderness and irritation of the lid margin and eyelid skin * Crusting along the eyelash line * Mucus build-up/discharge * Dacryocystitis - infection of the lacrimal sac Punctal stenosis is narrowing of the hole that can cause tearing. This can be caused by chronic use of medicated eye drops, changes from the aging process, viral infections, and dermatitis. This is treated by dilating the opening with a probe or by doing a two-snip punctoplasty to enlarge the hole. These can be performed in the office. Causes of blocked tear ducts * Chronic ocular irritation * Age-related changes * Chronic use of medicated eye drops * Nasal trauma or polyps * Chemotherapy medications (5-FU, Taxotere) Congenital nasolacrimal duct obstructions are not uncommon. Usually these will spontaneously resolve within the first few months. If they do not, a quick probing procedure can open up the system. To confirm an obstruction of the tear duct system, a probe and irrigation can be done to test for a blockage and to squirt a small amount of fluid into the system to see if it goes all the way through. Conservative treatments for partial blocked tear ducts would include using an antibiotic/steroid eye drop and a steroid nasal spray. There are two main surgical treatments. Silicone intubation involves putting tubing into the tear duct system and leaving it in there for 6-12 weeks. Dacryocystorhinostomy (DCR) creates an opening into the lacrimal sac and into the nose bypassing the opening in the sac that has scarred down. This is performed with local anesthesia (sometimes general anesthesia) as an outpatient surgery. Tearing usually improves within the first week. The most common complications are nose bleeds and failure to improve the tearing. DCRs have a 90-95% success rate. Conjunctivodacryocystorhinostomy (CDCR), a variant of traditional DCR, utilizes a glass (Jones) tube that is used when the canaliculi have also scarred.

Ep. 015: The New Category of Glaucoma Surgeries (MIGS) with Ashley San Filippo, MD
Dr. Ashley San Filippo returns to the Healthy Eyes 101 podcast to discuss MIGS (Minimally Invasive Glaucoma Surgery), a relatively new category of glaucoma procedures that have advantages over traditional glaucoma surgeries. Lowering eye pressure is the major goal of glaucoma treatment since this disease is not curable. Medicated eye drops, laser surgery, and traditional surgery are various ways to treat glaucoma. If patients are on maximum medical therapy with continued progression of their glaucoma, cannot tolerate the drops, or are non-compliant with taking their drops, then laser or surgical intervention may be necessary. MIGS has given patients a new avenue of treatment that has a much quicker post-operative recovery than traditional glaucoma surgery. While most MIGS are indicated to lower eye pressure in mild-to-moderate stages of glaucoma, their safety profile is favorable to trabeculectomies and glaucoma drainage implants. MIGS work by increasing outflow of the normal eye fluid or decreasing the production of the fluid. In the United States, most of the MIGS procedures have to performed in conjunction with cataract surgery. *Trabecular bypass procedures* * iStent and iStent Inject * Hydrus *Trabecular tissue incision/excision procedures* * Kahook Dual Blade goniotomy * Trabectome * Trab 360/OMNI * Gonioscopy-Assisted Transluminal Trabeculotomy *Laser endocyclophotocoagulation* Here is some more information on MIGS: * https://www.glaucoma.org/treatment/migs-the-new-age-of-glaucoma-surgery.php * https://www.glaucoma.org/treatment/what-is-migs.php Scroll down to the MIGS video on Dr. San Filippo’s glaucoma page to watch her explain iStent on a local news show.

Ep. 014: Learning About Macular Puckers and Macular Holes with Chirag Patel, MD
In this episode Dr. Suh interviews Dr. Chirag Patel, a retina specialist, about two conditions that can affect central vision - macula puckers and macular holes. Patients with a macular pucker (also called epiretinal membrane, epimacular membrane, cellophane maculopathy, and surface wrinkling retinopathy) will have symptoms of distortion or blurred vision that does not go away. A pseudohole is a variant of a macular pucker that looks like a macular hole. The majority of puckers occur spontaneously and without a cause (idiopathic). Secondary causes make up around 10-20% of cases and can be from from diabetic retinopathy, retinal vein occlusions, retinal tears and detachments, and trauma. After the age of 50, 2% of the population may have a macular pucker while 20% of people over 75 may have one. If there is a secondary reason for the pucker, this can occur at any age. Macular holes will also cause symptoms of blurring and distortion. The patient may also notice a missing area in the center of their vision. The cause of macular holes is probably related to the vitreous gel tugging on the macular region. This traction can pull off the center part of the macula and leave a hole. Macular holes can also occur after ocular trauma. People over 60 are more likely to have a spontaneous macular hole. Females are more prone to have them than males, unlike with puckers where females and males have about the same incidence. Diagnosis of both of these conditions can be done by direct examination of the macula and by OCT (optical coherence tomography). Patients with macular issues should monitor their vision with an Amsler grid to look for distortion or missing areas. Medications and lasers cannot be used to treat either condition. Surgery is the only treatment. Macular pucker surgery is only performed if the patient has bothersome visual symptoms. Patients with macular holes should have surgery when the retina specialist recommends it. Visual recovery after these surgeries may be slow, and patients may not recover 20/20 vision afterwards. The surgery should improve the distortion or the missing area in the center. The Retina Group, Dr. Patel’s practice, has excellent resources and surgical videos about macular puckers (epiretinal membranes) and macular holes on its website. Here are some other websites for more information on macular puckers and macular holes. Learn more about Dr. Patel and his practice at their website and Facebook page.

Ep. 013: A Comprehensive Review of Glaucoma Medications with Karl Pappa, MD
Dr. Karl Pappa, a glaucoma specialist, joins Dr. Suh on this episode to discuss all aspects of glaucoma medications. Glaucoma, a disease of the optic nerve, is thought to be worsened by increased eye pressure. The goal of treatment, whether it be with eye drops, laser or surgery, is to lower the intraocular pressure (IOP). Categories of Glaucoma Medications * Prostaglandin analogs * Xalatan (latanoprost), Lumigan (bimatoprost), Travatan Z (travoprost), Zioptan (tafluprost), and Vyzulta (latanoprostene bunod) * How they lower pressure: increases the outflow of fluid * Dosing: once at bedtime * Main side effects: eye redness, iris color change, eyelash growth, darkening of eyelid skin * Beta blockers * Timolol, Timoptic XE (gel-forming solution) * How they lower pressure: decreases production of fluid * Dosing: once or twice a day * Main side effects: low blood pressure, decreased pulse rate, fatigue, shortness of breath (in COPD and asthma patients), depression * Alpha agonists * Alphagan P (brimonidine) * How they lower pressure: decreases production of fluid and increases drainage * Dosing: two or three times a day * Main side effects: allergy to the medication, fatigue/drowsiness, burning or stinging, headache, dry mouth * Carbonic anhydrase inhibitors * Eye drops -Trusopt (dorzolamide), Azopt (brinzolamide) * Oral medications: Diamox (acetazolamide) and Neptazane (methazolamide) * How they lower pressure: decreases production of fluid * Dosing: twice a day for the drops; varies for the pills (follow instructions of your eye care specialist) * Main side effects: eye drops: stinging; pills: tingling of hands and feet, fatigue, stomach upset * Rho kinase inhibitor * Rhopressa (netarsudil) * How they lower pressure: increases the outflow of fluid * Dosing: once at bedtime * Main side effects: eye redness, stinging, tiny hemorrhages on the white of the eye Combination eye drops help with compliance and may be more economical. Examples include Cosopt (timolol/dorzolamide), Combigan (timolol/brimonidine), Simbrinza (brimonidine/brinzolamide), and Rocklatan (netarsudil/latanoprost). One reason patients have decreased compliance is because they can get ocular surface irritation and dry eyes from repeated use of drops that contain preservatives such as benzalkonium chloride (BAK). Several preservative-free options include Zioptan, Cosopt PF, and Timoptic in Ocudose. Several new drug delivery alternatives are being studied. The FDA recently approved Durysta (bimatoprost), a biodegradable sustained-release implant that is injected into the eye between the cornea and the iris. Obviously, compliance will not be an issue with this medicated implant but it will have to be replaced every few months. After instilling a glaucoma drop into your eye, close your eyes for up to five minutes to maximize absorption into the eyes and minimize systemic absorption to avoid some of the side effects. Here is another resource about glaucoma drops. To learn more about Dr. Pappa and his practice, visit Arena Eye Surgeon's website or find the practice on Facebook.

Ep. 012: A Deep Dive Into Macular Degeneration with Dominic Buzzacco, MD
Retina specialist, Dr. Dominic Buzzacco, joins Dr. Suh to talk about age-related macular degeneration (AMD), one of the most common causes of central vision loss in people over 50. People with early AMD will notice distortion, blurred vision, a blind spot, or, sometimes, nothing. Risk factors include: * Age over age 50 * Caucasian * Smoking * Family history (a first-degree relative increases the risk seven-fold) * Light-colored irises * Uncontrolled cardiovascular disease and high blood pressure Dry (non-exudative) AMD is by far the most common type and may be associated with retinal pigmentary abnormalities and soft drusen, yellow deposits found under the retina. About 10% of dry AMD patients will progress to the wet form. Wet (exudative or neovascular) AMD is characterized by the formation of abnormal blood vessels underneath the retina. These vessels may leak or bleed and cause scar tissue. Vision loss is more rapid with untreated wet AMD vs. the dry form. All patients with AMD should monitor their vision in each eye individually on a regular basis by using an Amsler grid. Patients with dry AMD should take AREDS 2 (Age-Related Eye Disease Study 2) vitamins to help slow down the progression of vision loss. Early diagnosis is important so that patients can be advised to start these eye vitamins. Patients who smoke should consider stopping. Those with wet AMD will probably need to have intraocular injections of so-called anti-VEGF medications to slow down or stop the abnormal vessel growth. The injections may contain the medications Avastin (bevacizumab), Lucentis (ranibizumab), Eylea (aflibercept), or Beovu (brolucizumab). These injections are not a cure but can keep the leaking or bleeding under control. Most patients will need monthly injections until all fluid / bleeding is absorbed and there is no evidence of recurrence. Some may need injections every eight to twelve weeks indefinitely. These medications have been a huge leap forward to stabilizing the disease in 95% of people and improving vision in 30-40% of eyes. Some risks of the injections include a subconjunctival hemorrhage (bruise) which goes away in a few days; temporary foreign body sensation; corneal abrasion; and intraocular infection (1:4000-5000 injections). Most patients will never go completely blind from their AMD even if central vision deteriorates because their peripheral vision remains intact. Some future treatments include a surgically implantable port (or reservoir) delivery system for injecting Lucentis. Gene therapy is also being studied to turn off the growth factors for abnormal blood vessels. Unfortunately, some AMD patients may lose enough of their useful vision to perform daily activities. Low vision aids can help those with permanent vision loss. Services are available to assess the types of devices that patients may need to help them function better. Here are some more resources on macular degeneration. Article #1 Article #2 To find out more about Dr. Buzzacco and his practice, go to Midwest Retina’s website.

Ep. 011: Everything You Wanted to Know About Retinal Detachments with Sugat Patel, MD
Dr. Sugat Patel, a retina specialist, joins Dr. Suh to discuss retinal detachments (RD), a potentially sight-threatening condition. Around 5 in 100,000 people per year will develop a retinal detachment. A posterior vitreous detachment, separation of the liquefied vitreous gel from the retina, will occur eventually in most people. It is a major cause of flashes of light or floaters in the vision. Sometimes this may also lead to a retinal tear. If the normal inner eye fluid (aqueous) gets under the retina through the tear, then the retina will lift off of the eye wall. This is a rhegmatogenous retinal detachment. When the retina detaches, most people will notice a scotoma, or a dark/blind spot, in their side (peripheral) vision. This scotoma may get bigger quickly and infringe on the central vision. This is an emergency and the patient needs to be evaluated by an eye care specialist immediately. Trauma and myopia (nearsightedness) are risk factors for this type of RD. Exudative detachments occur when fluid leaks from the choroid, the nutrient layer underneath the retina. This can happen from uveitis (inflammation), bleeding, or an ocular tumor. Tractional detachments occur when something inside the eye is pulling on the retina such as scar tissue from advanced diabetic retinopathy and retinopathy of prematurity. Retinal tears can be treated with an in-office laser or with cryopexy (extreme cold therapy). Laser retinopexy is the more common way to treat this condition because it seals the tissue down quicker and with less inflammation. For patients with small, asymptomatic RDs, laser retinopexy can be performed instead of surgery in the operating room. Even larger, asymptomatic RDs with tears in the upper part of the retina can be treated in the office with pneumatic retinopexy where a gas bubble is injected into the vitreous cavity to push the retina back into place. Laser or cryopexy is then used to seal down the area around the tear. If a RD needs to be fixed in the operating room, various techniques can be used alone or together to fix the retina. A scleral buckle is a band that encircles the eye to help bring the eye wall closer to the retina. A vitrectomy is surgical removal of the vitreous gel which is what usually tugs on the retina in the first place. Laser is then used to seal the area around any retinal tears. Sometimes a gas bubble or silicone oil may be used to keep the retina in place. All RDs need attention quickly, but macula-on detachments should be fixed more urgently because the macula is still functioning and has not separated yet. The center of the macula (fovea) is the most important area of the retina that enables one to see to read and to see details far away. Post-operatively, patients may have some discomfort. With scleral buckles, there may be some double vision, which is usually temporary, because the buckle goes underneath the eye muscles. If a gas bubble is placed, the vision may be very fuzzy for several days. The patient may need to be in a certain head position for two to ten days to let the gas bubble push against the area where the main part of the detachment was located. The success rate for primary RD repair is around 90-95%. Some risk factors for re-detachment include younger age, trauma, and underlying inflammation.

Ep. 010: The One-Eyed Surgeon With Only One Thumb and Other Stories - with John C. Barber, MD
In this tenth episode, Dr. Suh takes a departure from his usual format to interview his ophthalmology residency director and chairman, Dr. John Barber, about the three books he has written since retirement. His first book, The Joy of Medical Practice: Forty Years of Interesting Patients, is about the many interesting patients he has encountered from his medical school years to his last years in practice. In his second book, Hey, Doc! What’s Wrong with My Eye?: A General Guide to Eye Symptoms, Dr. Barber writes about common symptoms and diseases of the eye and discusses treatments. Some common causes of red eyes include: * Conjunctivitis – often called pink eye, the translucent outer coating (conjunctiva) in front of the white part of the eye (sclera) becomes inflamed from viruses, bacteria, allergens, or chemicals * Corneal abrasion – a scratch on the outer layer of the cornea usually from trauma * Corneal ulcer – an infection on the cornea that can be caused by var…

EP. 008: Is It Safe to Get Your Eyes Examined During the COVID-19 Pandemic? - with Laura Kunze, MBA, COE
On this special episode, Dr. Steven Suh and practice administrator, Laura Kunze, discuss the new procedures and protocols to ensure patient safety during their eye exam to minimize the risk of potentially spreading the coronavirus during this historic pandemic. Please understand that this episode came out in early June of 2020 so these rules may have changed by the time you have listened to this. Before the day of the appointment, we are pre-screening patients by asking them if they have had a sore throat, fever, fatigue, loss of smell or respiratory symptoms. On the day of their appointment, we will check their temperature to make sure that they do not have a fever. If they do, they will be asked to re-schedule. Wearing masks are mandatory from the time they walk into the office until they leave. All doctors and staff are to wear their masks full-time as well. We ask that family members stay in their cars unless there is a need for them to accompany the patient. In the waitin…

Ep. 007: Indications for Scleral Contact Lenses with Katie Wulff, OD
In this episode Dr. Steven Suh interviews Dr. Katie Wulff, an optometrist, about a specialty gas-permeable contact lens called scleral lenses. Some people have abnormal corneal curvatures and irregularities which make it difficult for them to see even with glasses or soft contact lenses. Stephen Curry, an NBA star with the Golden State Warriors, wears scleral lenses because of his corneal condition called keratoconus. Rigid gas-permeable contacts (RGP) and scleral contact lenses have a smooth, spherical, and hard surface which will neutralize these irregular “hills and valleys” on one’s cornea. The reason soft contact lenses do not work as well is because they “mold” onto these corneas and do not vault over them, thus replicating the abnormal curvature. Regular RGPs can be helpful in many cases but they have limitations. Scleral lenses do not sit on the cornea like RGPs but sit on the white part of the eye (sclera) so they are usually more comfortable. Scleral contact…

Ep. 006: Keratoconus and Corneal Cross-Linking with Kenneth Beckman, MD
Dr. Steven Suh interviews Dr. Kenneth Beckman about a debilitating, corneal thinning condition called keratoconus. The incidence is approximately 1 in 2,000 individuals. The major risk factors include atopic disease, Down’s Syndrome, some family history, floppy eyelid syndrome, and chronic eye rubbing. Symptoms * Initially patients may be asymptomatic * Blurred or distorted vision from increasing nearsightedness and/or astigmatism * Increased sensitivity to bright light and glare, which can cause problems with night driving * A need for frequent changes in eyeglass prescriptions * Sudden worsening or clouding of vision Keratoconus can be diagnosed in the late teenage years and can worsen as time goes on. Corneal topography is the main tool for diagnosis. Treatment * Early: glasses, soft contact lenses, gas-permeable contacts, then specialty contacts called scleral lenses * Later stages: traditional treatment has been corneal transplantation * May have long re…

Ep. 005: Contact Lens Basics with Julia Geldis, OD
On this show Dr. Steven Suh and Dr. Julia Geldis have a thorough conversation about contact lenses. Contact lenses have some advantages over glasses. People with higher prescriptions find that they are more comfortable from a vision standpoint because contacts do not cause as much minification or enlargement of images as with glasses.
