Development The Heart of the Giver

An almost 30-year career in ophthalmology has inspired an alumnus to come full circle. Dr. David B. Birnbaum, who graduated from the Medical College of Georgia in 1986, recently donated $50,000 to the Department of Ophthalmology, prompting the Eye Care Center resident room to be named in his honor.   “I had a great time in Augusta and it was the perfect time in my life,” says Birnbaum. “I went to medical school, internship, and residency at the Medical College of Georgia.”   He cites faculty including Drs. John Davis, Keith Green, Robert Harbour, David Hull, Malcolm Luxenburg, and Robert Summerer as mentors, noting, “They were all excellent teachers as well as clinical faculty.”   He was inspired by his fellow residents, as well.   “All of the residents were very good friends,” says Birnbaum. “The residents were helpful to everyone, wanting for each person to do well.”   One of his most memorable rotations was in the Charlie Norwood Department of Veterans Affairs Medical Center, observing, “They allowed the residents to have more responsibility in patient care.”   After completing his training, he served in the U.S. Air Force, completing a three-and-a-half-year commitment, then staying on another 18 months, earning a Meritorious Service Medal.

“I ended up staying five years total because I liked it so much.”   Next, he embarked on a 16-year career with the Premier Medical Group in Clarksville, Tenn. “I did over 5,000 cataract surgeries and had a lot of happy patients,” says Birnbaum. “I did a full range of procedures, including laser surgery for glaucoma and diabetic retinopathy, eyelid plastic surgery, strabismus surgery, and minor procedures.”   He considers his gift to MCG “a way to show my appreciation, to do something that made me feel good and to thank those at MCG.   “One of the residents told me after a recognition meeting of my donation that he was happy I gave,” says Birnbaum. “I told him I was happier than he was.”

This plaque above will reside in the resident room at Georgia Regents Medical Center.

Research

The Eye of the Beholder

  Have you ever fumbled around for your keys in low light? Perhaps you found your cell phone and pens, but not your keys? How is it that the brain determines what we feel is what we see? These senses of sight and touch and how the brain interprets their meanings are being researched at Georgia Regents University to help those with visual impairments.   Dr. Jay Hegdé, Associate Professor in the Department of Ophthalmology Culver Vision Discovery Institute and Brain and Behavior Discovery Institute, has received a National Institutes of Health grant to glean more information.   “This grant explores the way the brain interprets what we see and what we touch, multisensory perception,“ says Hegdé. “For instance, Braille is a case where people with visual impairments use their hands to either augment or compensate for what their eyes can’t see. Essentially, they are using their fingertips as seeing eyes.”   Hegdé, a brain researcher who sees the brain as the last true frontier, explains that the brain is hungry for any information to make sense of “what is out there.” He hopes to teach those with visual impairments to translate what they feel with their fingertips into data other people gather visually.   “The brain essentially avails itself of whatever it can sense and combines it, even in a healthy brain,” says Hegdé. “The brain doesn’t have compartments. It makes use of whatever source of information that it can get a hold of in order to do to carry out the basic functions of life. For instance, the brain may be faced with the

problem of deciding whether to combine the touch information from your left or right hand with what the eyes are seeing at a given moment. It uses synchronicity to make determinations – it looks at whether what is in the left hand or the right hand is synced with what the eyes see.” He is exploring the parameters of both healthy patients and patients with various visual deficits, hoping to harness the innate abilities of the brain to compensate for vision impairment.

His inspiration came in the smallest of packages.   “Something happened when one of our goddaughters was diagnosed with retinoblastoma (cancer of the eye),” says Hegdé. “For a while, the only options for her seemed to be turning her blind to save her life or risking her life to save her sight.”   Tough choices came and went. But eventually, surgeons were able to remove the diseased part of her eye, and it turned out she had a very mild form of the disease. Her vision is impaired, necessitating rehabilitation, but her future is bright.   “Because of what she means to us, and to me personally, I feel like really nothing I do makes any sense except in light of what it means for her, or patients like her, especially children like her,” says Hegdé. “If all I do is help my little goddaughter Susie and children like her, I will take it, I will take it any day of the week, and twice on Sunday.”

Pro g ram Update Optimizing Participation in Daily Living Activities

  Imagine being unable to determine if a stove is on or off ... unable to read a computer screen ... unable to separate lights from darks before washing clothes.   Dr. Mariana D’Amico, Associate Professor of Occupational Therapy and Director of the GRU Low Vision Rehabilitation Center, has devoted her career to addressing these and other potential challenges for those with low vision.   The center, which opened in February 2012, helps those with low vision sustain their daily living activities. The patients—approximately 70 and counting—are referred from the GRU Ophthalmology Clinic to learn techniques to help them with activities including cooking, reading, and self-care. The clinic’s adaptive equipment enables them to practice while supervised and instructed by D’Amico.   “Basically, we look at adaptive equipment and techniques that the client and I determine would be beneficial based on their evaluation,” says D’Amico.    “One example would be using high-contrast markings or textured dots to identify ‘medium’ and ‘off’ on stove knobs.”   She also teaches patients how to optimize lighting conditions during daily activities.   D’Amico involves family and caregivers as well, discussing things such as home modifications.

VISION

  “My goal is to educate the patients and their family or caregivers so they can sustain and maintain a quality of life in their homes and communities,” says D’Amico.   D’Amico operates the clinic single-handedly but draws on a wide network of support, including ophthalmologists, related specialists, and campus resources such as a driving simulation lab.

Member Folio

Dean Sets Sights on Corneal Advances Fast Facts Watsky earned his doctorate in physiology at the Medical College of Wisconsin and completed a postdoctoral fellowship in physiology and biophysics at the Mayo Foundation in Rochester, Minn. He received the Silver Fellow Award from the Association for Research in Vision and Ophthalmology in 2010.   Dr. Mitchell Watsky joined Georgia Regents University June 1 as Dean of The Graduate School and Professor of Cellular Biology and Anatomy.

Transformational Research       Currently researching wound-healing in corneas, Watsky began something transformational nearly 20 years ago—helping create an artificial cornea.   “It started out as an idea between my primary collaborator on the project, Dr. May Griffith, who is now at the Swedish institute Linköping University,” says Watsky.   The research, originally funded by Procter & Gamble Co., was intended to find non-animal alternatives for toxicology testing. Watsky and Griffith designed a test-tube cornea with tissue entirely derived of human cells.   “The idea was to be able to use it for experimental purposes,” says Watsky. “The test-tube cells were used to study [things such as] wound-healing and toxicology studies.”  

Test-Tube Cornea

  The test-tube cornea is now in clinical trials to be used on humans as an alternative to donor eye tissue.   “If you need a cornea transplant in the United States, you get it from a human donor,” says

Watsky. “In the United States, there isn’t really a problem with tissue availability, but worldwide, it is a very big problem.”

Research at Georgia Regents University

    Watsky’s current research, funded by the National Institutes of Health, builds on his finding that the cornea can make vitamin D. “The main source of vitamin D through the body is via sunlight exposure to the skin, and the only two parts of the body that are exposed to sunlight are your skin and your eyes,” he says. “It’s been that a number of different tissues, tissues that everybody originally thought not to be involved in vitamin D metabolism, can make vitamin D, or at least activate it. So, we wanted to know if that was true in the eye. We’ve now determined that the cornea can indeed make vitamin D, and now we are examining the physiological significance.”   Watsky also studies how bioactive lipids affect corneal wound-healing and corneal fibrosis. These studies have expanded to look at other fibrotic disorders of the body, including systemic fibrosis, or scleroderma. Watsky has discovered that these lipids interact with ion channels of certain cell types to promote fibrosis. His goal is to reverse this process.
