What is AMD?

Age-related Macular Degeneration (AMD) is a devastating retinal degenerative disease that affects the macula, the part of the eye that provides sharp, central vision. Those who suffer from this progressive disease are unable to drive, read or recognize faces. In AMD, vision loss is the result of the death or dysfunction of retinal pigment epithelial cells (RPE) that provide nutrients and support to the light sensing photoreceptor cells in the eye.

There are two forms of AMD: wet and dry. In the wet form of macular degeneration (known as choroidal neovascularization or CNV), abnormal blood vessels grow under the macula and retina. Fluid from leakage of these blood vessels accumulates and cause vision loss or distorted vision. In dry AMD (non-neovascular form) small yellow deposits form beneath the retina, which can ultimately lead to geographic atrophy (GA) or the advanced form of dry AMD. Dry AMD is the most prevalent form of macular degeneration and can be stable for many years without vision loss. Patients diagnosed with GA have severe loss of vision and a tangible impact on quality of life. To date, there is no cure or known treatment options for GA.

Who is at Risk?

In general the global burden of AMD remains substantial as a result of the aging population. Globally, the projected prevalence of AMD in 2020 is 196 million, increasing to 288 million in 2040. The main risk factors for AMD are age and race. Among Americans of European decent, the prevalence of AMD is projected to rise to nearly 5.44 million by 2050 according to reports from the National Eye Institute. A significant increase in the rate of AMD amongst minority populations has also been observed. Most notably, a six-fold rise of AMD has been reported in persons of Hispanic decent.

Other risk factors for AMD include positive family history, smoking, hypertension, high cholesterol and obesity.

How is AMD Diagnosed?

Pay attention to the signs of early disease including distorted vision and your risk factors for developing AMD. Please make an appointment to see your eye care specialist at least once a year if you are over 40 years of age, if you are at risk as a result of ocular and medical history, family history, age, or race and especially if you are noticing vision loss. Your ophthalmologist or optometrist will conduct a comprehensive eye exam, which will include dilated eye exams, visual acuity, and optical coherence tomography (OCT). Following a thorough assessment, your physician will work closely with you to determine the best course of action.

Are There Treatments for AMD?

In general there is no known cure for AMD. However, for the wet form of AMD, drug treatment options include anti-VEGF (vascular endothelial growth factor) therapies. Such therapies reduce the level of VEGF, a protein known to stimulate abnormal blood vessel growth in the retina and macula. These drugs are administered as injections directly into the eye.

Thus far there is no FDA approved treatment available for dry AMD. USC vision researchers, Dr. Mark Humayun and David Hinton, funded by the California Institute for Regenerative Medicine, have recently developed a novel stem cell-based therapy for the treatment of advanced dry AMD. The treatment consists of a patch of RPE cells derived from stem cells that is grown onto a polymer scaffold and implanted behind the diseased portion of the eye. A clinical trial is currently underway to evaluate this potential treatment at USC and is led by Assistant Professor of Clinical Ophthalmology, Dr. Amir Kashani. Enrollment in the phase I/IIa clinical trial is ongoing for this stem cell-based treatment.

Univision Host: I present to you Cristian Martínez!

Cristian: [Shakes hand] Nice to meet you!

Univision Host: Welcome to the studio Cristian. So you are studying to be an Ophthalmology assistant. I actually did not know that Ophthalmologists required assistants.

Cristian: Many people do not know what an Ophthalmology assistant is. We help the doctor to perform all the exams – whatever the doctor might need.

Univision Host: How long does it take you to receive this certification?

Cristian: Less than two years, and later when you finish the program, you are given a certificate to work in Ophthalmology in various departments. There is a lot of work [In Ophthalmology].

Univision Host: There is a lot of work. You already have a job though you have not yet graduated?

Cristian: Yes, yes I have a job [in clinic] for 2 months.

Univision Host: How crazy! And you haven’t yet graduated! Tell us a bit about your story. You were studying in San Francisco and paying a lot of money for your career…

Cristian: Yes, it was a lot of money. Later, I returned here to Los Angeles to enter the program, and it was less money than in San Francisco.

Univision Host: A lot less money, and now you have a job!

Cristian: Yes, and now I have a job.

Univision Host: This is really interesting – [Shows photo slideshow of OTEP students] — So this an example of what you do at the USC Roski Eye Institute OTEP Program. Here we can see you working.

[Photo slideshow continues to play]

Cristian: Yes! Before the doctor comes, we help with part of the visual exams, checking in the patients, answering their questions and so on.

Univision Host: Do you want to be an ophthalmologist? And do you want to continue in this career path?

Cristian: Yes, When I finish the program, I would like to continue working at USC in Ophthalmology.

Univision Host: So after you get your certification, you start to work and build experience and continue with this career..

Cristian: Yes, yes [in agreement].

Univision Host: Wow – it would have been very different if you had stayed all this career time elsewhere [San Francisco]. And you haven’t paid as much here.

Cristian: No, what I like about the program is I can do the certification and get experience.

Univision Host: And there are a lot of young men studying this, or is this new?

Cristian: It’s not new, but there aren’t a lot of young men studying this.

Univision Host: And to be able to speak Spanish is also very helpful.

Cristian: Yes it’s very good. If you speak Spanish, it’s really good because you use Spanish every day, and with many patients.

Univision Host: And now you work in an office with real patients.

Cristian: Yes, at the hospital at USC.

Univision Host: So you work at USC, they pay you a salary, you study for your certification, and you can continue with this career?

Cristian: Yes!

Univision Host: It seems to me these are all very beneficial!

Cristian: Yes, absolutely.

Univision Host: Your parents will be very proud – are you the first generation to go to university?

Cristian: Yes, I am the first.

Univision Host: [Turns to audience] – and there it is for you to see – thank you so much!

Cristian: Thanks to you!

He’s Making a List and Checking it Twice…

Safe Toy Blog Post final

 

Deciding what to buy your children for the holidays is always challenging. Check twice before making a purchase and be mindful of age and potential toy safety hazards. From newborns to toddlers, a child’s vision continues to develop through early and middle childhood. From the first day you look into those precious eyes, your baby begins to create essential connections between the eyes and brain, which will allow their vision to develop focus, hand-eye coordination, depth-perception and color vision.

To Prevent Toy-Eye Injury

  • Read toy labels and purchase according to the advised age group
  • Always ensure the toys are safely assembled
  • Show the child how to play with them
  • Supervise playtime
  • In general, avoid hard objects with sharp, pointy edges

Holiday Toy List by Age

Newborns

Babies slowly begin to focus on objects, see contrast and are sensitive to light. Purchase plush textured toys and bright colored visual toys with contrast like mobiles. For mobiles, ensure they are correctly assembled and a safe distance away form the infant.
 

1-12 Months

Hand-eye coordination begins to improve at this stage. Progress in depth-perception and color vision are also occurring. Avoid sharp edges and heavy objects. They should be encouraged to crawl and reach for things. Toys like balls, stacking toys, musical toys, large piece puzzles are ideal at this age.
 

1-2 Year-Olds

Children can recognize objects and faces well. Their hand-eye coordination has developed and they should be able to scribble and color. Ideal toys include, finger paint, books, stuffed animals, blocks, and large lego. Near the end of this stage larger items, like kitchen sets, household toys, play-gyms are safe to play with.
 

3-6 Year-Olds

By now children become more independent, have greater depth-perception and can control their movements. Tricycle or bicycles with helmets, balls, board games, crayons etc. are suitable. Avoid toy-guns with soft pellets, which can cause serious eye injury and permanent vision loss. Recent incidents involving soft-pellet toy guns have been reported by the British Medical Journal where three children were treated for pain, blurred vision and even internal bleeding in the eye.
 

7-11 Year-Olds

Children at this age can enjoy a number of toys safely such as coloring sets, books, balls, puzzles, musical instruments, microscopes, telescopes, and sports equipment. When purchasing tablets, small video games or computers one should consider limiting screen time. Staring at screens up close like playing video games or watching shows or movies can result in poor vision. Incidence of childhood myopia (nearsightedness -inability to see objects at further distances) among American children has more than doubled over the last 50 years in large part due to the close work and use of mobile devices and screens on a daily basis, combined with a lack of outdoor activities and sunlight.

Have a safe and happy holidays from the USC Roski Eye Family!!

What You Need to Know if You Have Diabetes

Diabetes blog cover 2

Diabetes is a leading cause of blindness in the nation, and can lead to serious eye conditions and even permanent vision loss. Diabetic eye disease consists of group of eye conditions including diabetic retinopathy (DR), diabetic macular edema (DME), cataract and glaucoma.

The facts

  • Adults diagnosed with diabetes are 2-5 times more likely to develop cataracts.
  • Your risk of glaucoma is nearly doubled with diabetes.
  • Tractional retinal detachment is a serious complication that can occur in those with diabetes and can cause permanent blindness.
  • Diabetic retinopathy is the most common diabetic eye disease and is estimated to affect 28.5% of diabetic people in the U.S. The disease damages the retina, neural tissue in the back of the eye responsible for processing images, as a result of inadequate blood supply of oxygen to the blood vessels.
  • Diabetic macular edema is a consequence of DR and results in the swelling of the macula, a very sensitive area of the retina which is responsible for fine vision.
  • Patients with diabetic eye complications are at increased risk of cardiovascular disease. Thus their physicians should follow persons with type 2 diabetes and more severe stages of DR more closely.

Signs of diabetic retinopathy can include

  • Blurred vision
  • Spots or strings floating in your vision
  • Poor night vision
  • Black areas in your vision
  • Vision loss

Vision loss from diabetes can be preventable. Please visit your eye care professional today

September 7th, 2017: In a lively ceremony held in the new, fourth-floor of HC4 location, USC Roski Eye Institute faculty, USC President Max C. Nikias, USC Provost Michael Quick, Keck Medicine of USC CEO Tom Jackiewicz and USC Trustees Gayle and Edward Roski to officially open the new USC Roski Eye Institute clinic.

“Together, we have celebrated many successes at the USC Roski Eye Institute, but today stands out as particularly special,” Nikias said. “This beautifully remodeled clinic is all about vision – saving it, preserving it and restoring it. You, the doctors and the staff who bring this clinic to life, stand at the fore of this important efforts and are the finest in the nation.”

“Dean Varma and Dr. Mark Humayun, the clinic’s co-directors, have assembled a team of doctors and staff who are expert at lifting the clouds from our vision,” Nikias continued.

Nikias then expressed his profound gratitude to the Roskis for their vision and generosity.

Gayle Roski, a noted artist in addition to her work as a philanthropist, was treated for cataracts by Keck Medicine ophthalmologists, and as a result, “she and Ed resolved to find an institute with the most ambitious goal possible – to eliminate blindness.”

“With their support, the USC Roski Eye Institute is stronger than ever. It’s one of the top-two funded eye institutes in the nation and a leader in research funding from the National Institute of Health,” Nikias continued. “Its residency program runs in the top ten nationwide, and it just expanded for the first time in years. And in 2016 this institute, my fellow Trojans, treated more than 100,000 patients.”

“It’s an honor to help support people who will be behind the new breakthroughs in the future of this field,” Gayle Roski said. “And I want you to know that Ed and I are grateful for your presence here today and thankful for the work you do each and every day.”

With the conclusion of remarks, Gayle Roski officially unveiled the clinic’s striking signage and invited attendees to tour the new, state-of-the-art facilities, which includes 31 patient rooms, an out-patient surgical area, labs, a staff lounge and more.

Blind USC Trojan, Jake Olson, Snaps His Way into History

In a truly inspiring event that will no doubt go down as one of the best moments in USC Trojan football history, Jake Olson, the Trojans long snapper who has been blind since the age of 12, carried out a perfect snap to help USC defeat Western Michigan in the first football game of the 2017 season this past week.

Jake was diagnosed at a very early age with retinoblastoma, a rare cancer that is the most common ocular tumor in children causing blindness. Approximately one in 17,000 children are diagnosed with retinoblastoma each year. At the age of one month, Jake’s left eye was surgically removed as the disease had aggressively advanced. Over the next 12 years, Jake underwent ongoing treatment for his eyes at the Children’s Hospital of Los Angeles (CHLA); unfortunately, retinoblastoma was affecting his right eye as well. The tumor recurred more than a dozen times and was eventually removed – rendering him permanently blind.

As a young boy, Jake had a passion for football. Before losing complete vision, Jake fulfilled his dream of meeting the USC Trojan’s football team, which was initiated by former USC head coach Pete Carroll. Learning to live with his vision loss, Jake persevered to make his football dreams a reality by officially becoming a long snapper on the USC Trojan roster in 2015. Embodying the true spirit of a Trojan, Jake finally had the opportunity to snap his first ball in last week’s USC home opener, proving that anyone can overcome a disability and become an inspirational force.

“I just think there’s a beauty in it,” Olson said in the postgame wrap-up interview with the Los Angeles Times. “If you can’t see how God works things out, then I think you’re the blind one. I think to have a situation where a 12-year-old kid loses his sight and is going to have to face the rest of his life without seeing is just ugly, and to fast forward eight years and have that same kid be able to snap on the football field that really got him through that time, is just really just special and incredible.”

In addition to receiving the required clearance by the NCAA to play, Jonathan Kim, MD, associate professor of clinical ophthalmology and director of the Ocular Oncology Service at the USC Roski Eye Institute, also provided clearance for Jake to play college football. Kim examined Jake to ensure that the cancer had not returned and that he was healthy enough for the aggressive physical action of college football. He also reviewed with Jake the safety measures and guidelines to avoid injury when playing a high contact sport, such as college football, while also wearing ocular prostheses. Kim continues to see Jake as a patient on a regular basis for routine surveillance and care of any eye health issues that may arise.

“As part of the USC Roski Eye Institute and Trojan family, watching Jake snap that football was a proud moment for us all,” said Kim. “Jake accomplished something that few of us can only dream of with or without visual impairment, and he is a true inspiration to all patients suffering from retinoblastoma.”

Several researchers from the USC Roski Eye Institute and CHLA have made great strides in the pursuit to find a cure for Retinoblastoma. Among them, David Cobrinik, MD, PhD, USC associate professor of research ophthalmology, focuses on understanding the behavior of the cells that give rise to retinoblastomas. He has identified the cell of origin, which was published in Nature in 2014. Jesse Berry, MD, assistant professor of clinical ophthalmology is currently developing a minimally invasive method to diagnose retinoblastoma in the eye, known as “surrogate liquid biopsy” that provides earlier treatment intervention. USC Roski Eye Institute researchers hope to one-day develop novel approaches like retinal regeneration treatments to prevent retinoblastoma from forming in predisposed children.
