FDA Approves First Long-Term Implant for Glaucoma

New Glaucoma Treatment is Showing Great Promise

In exciting news for glaucoma patients who dislike or have difficulty with eyedrops, the FDA has approved Durysta™, a new long-term, biodegradable eye implant that helps regulate eye pressure in people with ocular hypertension or open-angle glaucoma.

A doctor can implant 10 micrograms of bimatoprost, prostaglandin analog (a common class of glaucoma medication) directly into the anterior chamber of the eye with a single-use applicator. The implant will release the drug over a period of 12 weeks.

In clinical studies, this treatment lowered intraocular pressure by 30% over three months. Over 80% of patients no longer needed other treatments, like medicated eyedrops. The non-compliance for the use of glaucoma eye drops is as high as 80% among glaucoma patients, according to Allergan, the company that developed Durysta, so this could potentially become an alternative to daily medications.

“FDA approval marks a breakthrough milestone for the glaucoma community and provides a much-needed option for patients challenged with topical drops or needing alternative options,” said David Nicholson, Allergan’s chief R&D officer.

National Glaucoma Research funded early studies by Dr. Shahid Hussain on prostaglandin analogs that increased the understanding of how this class of drugs works.


President’s Corner

Thank you for supporting National Glaucoma Research at a time when your help has never been more important. Because of you, the researchers who are at the forefront of scientific discovery can push the frontier of glaucoma knowledge to new and exciting places while changing lives.This issue of National Glaucoma Research Report discusses new advances in treatment, the risks and benefits of glaucoma surgery, and spotlights Haiyan Gong, MD, PhD, a National Glaucoma Research-funded researcher whose work brings us new insights to develop better ways to treat this sight stealing disease. We are committed to funding the most promising research studies. But it is only because of the support we receive from you and other dedicated friends that we can continue to improve the lives of people with glaucoma.Thank you for your partnership in the fight to cure glaucoma.

The Benefits and Risks of Glaucoma Surgery

As with any operation, there are risks associated with glaucoma surgery. But for many people with advanced cases of glaucoma, the benefits of surgery outweigh the risks. Here are some of the risks and benefits you can discuss with your ophthalmologist.

  • Vision Loss: In the short term after anoperation, vision is temporarily disrupted.In very rare instances, permanent vision canbe reduced or lost.
  • Bleeding in the Eye: Patients with verylow eye pressure may experience thisuncommon, but serious, complication.Talk with your ophthalmologist if you areon blood thinners.
  • Infection: On very rare occasions, aninfection inside of the eye can occur, evenmonths or years after surgery. If you havesigns of infection, call your ophthalmologistimmediately. Caught early, most cases canbe treated with antibiotic drops.
  • Scarring: As the eye naturally heals ordevelops scars from the surgery, eye pressurecan become higher than intended. This canrequire restarting glaucoma medication, or arepeat surgery.
    While it is important to understand the risks discussed above, it is also important to recognize that the vast majority of glaucoma surgeries are successful at slowing the progression of glaucoma and achieving the intended eye pressure. Your ophthalmologist will help you explore your options when the time is right.​

SPOTLIGHT ON ... Haiyan Gong, MD, PhD

Decreasing Intraocular Pressure
Haiyan Gong, MD, PhD

A primary risk factor of glaucoma is abnormally increased pressure inside the eye. Th is is usually due to inadequate drainage of the aqueous humor, the clear fluid that fills the space in front of the eyeball between the lens and cornea. Currently, the only way to treat glaucoma is to lower this eye pressure.

Haiyan Gong, MD, PhD, is a professor of Ophthalmology, Anatomy, and Neurobiology at Boston University School of Medicine. Current funding from National Glaucoma Research is supporting Dr. Gong’s research on how pressure in the eye is regulated, with a recent focus on the role of the protein thrombospondin-1 (TSP1). TSP1 aff ects how well the eye can drain its aqueous humor. Removal of this protein can result in lower eye pressure in a person diagnosed with glaucoma. Dr. Gong’s ongoing research will determine if TSP1 defi ciency could prevent or reduce steroid-induced eye pressure.


Save Your Sight From Glaucoma

Knowing the risk factors for developing glaucoma can help prevent this devastating disease from stealing your vision.

STRONG RISK FACTORS

  • High eye pressure
  • Thin cornea
  • Family history of glaucoma
  • Suspicious optic nerveappearance
  • Being older than age 40 for African Americans or older than age 60 for thegeneral population

POTENTIAL RISK FACTORS

  • Severe Nearsightedness
  • Diabetes
  • Eye surgery or injury
  • High blood pressure
  • Use of corticosteroids
  • Farsightedness
  • Eye surgery or injury
  • Cardiovascular Disease
  • Low eye pressure

Early diagnosis and treatment are key to saving your sight from glaucoma.


Southwestern Frittata

The Italian version of an omelet, this frittata is made with egg whites instead of whole eggs to reduce calories, fat, and cholesterol.

Ingredients
1/2 green or red bell pepper, diced

Instructions
1.Heat your broiler and place the rack four inches from the heat source.
2.Coat an ovenproof skillet with cooking spray. Add peppers and mushrooms, then sauté overmedium heat until tender.
3.In a separate bowl, whisk egg whites together with a 1/2 cup of the salsa.
4.Pour into the skillet with the vegetables and cook until partially set. About five minutes. Don’t blend or scramble. Sprinkle with cheddar cheese.5.Place the skillet under the broiler and cook until cheese melts and eggs set, about five minutes.6.Split the frittata into two portions, garnish with salsa, and serve.
Makes 2 servings.

How to Choose the Best Ophthalmologist for Glaucoma Surgery

Choosing the best ophthalmologist for glaucoma surgery can feel daunting. Here are the steps Yvonne Ou, MD, would take in order to identify a surgeon for herself or a family member.

1. Find a glaucoma fellowship-trained ophthalmologist
Ophthalmologists with fellowship training have completed an intensive year of training focusing on glaucoma clinical care and surgery under the supervision of glaucoma specialists.

2. Is the ophthalmologist certified by the American Board of Ophthalmology(ABO)?
This involves passing both a written andoral examination. I would recommend identifying an ophthalmologist who is board-certified by searching for them on the ABO website.

3. Obtain word-of-mouth referrals
This can include the ophthalmologist oroptometrist who might be referring you or asking your primary care physician.

4. Determine the experience of the surgeon
When meeting with your surgeon, besure to ask them what their experience iswith the particular surgery they are recommending. Evaluate how carefullythey explain why they recommend thatsurgery for you. Ask about the risks and benefits and consider how well they listen to your needs and preferences. It is important that both of you are onthe same page.

5. Seek a second opinion
Consider seeking a second opinion, but do not be surprised if the opinion is different. Because there are more surgical options for treating glaucoma now, different surgeons may have different preferences for surgeries. A second opinion can help you verify whether the surgery recommended by one ophthalmologist is a reasonable option, even if the second recommends a different one.
