Finding success in retinoblastoma treatment

The idea of your child having an eye removed is shocking, an extremely difficult thing for a parent to cope with, says Baker Hubbard, MD, Thomas M. Aaberg Professor of Ophthalmology, and a pediatric ocular oncologist. Actually, says Hubbard, most children who lose an eye adapt very well and enjoy essentially normal lives.

Baker Hubbard, MD

Retinoblastoma is cancer that forms in the tissues of the retina (the light-sensitive layers of nerve tissue at the back of the eye). Retinoblastoma usually occurs in children younger than age five. It may be hereditary or nonhereditary (sporadic), and is caused by mutations in genes.

To six-year-old Emilia McKibbin, having a prosthetic eye is no big deal. She knows to protect it—wearing her glasses for school and playtime, donning a scuba mask at the beach—but it doesn’t limit her choices.

Following her interests, Emilia has earned a gold belt in karate. She’s learning gymnastics. She swims. She loves to romp with Daisy, her black cocker spaniel. And while most people don’t even notice that one of this little girl’s shining dark-brown eyes is different from the other, Emilia shares her story with a few. “I tell my teachers and my friends that I have a special eye,” she says.

Eye diseases and immune system link studied

Drawing shows areas of the eye

Emory Eye Center researchers are looking at the role of the immune system in the inflammation of the eye and the progression of eye diseases.

Santa Ono, PhD, professor of ophthalmology, Emory School of Medicine and researcher at the Emory Eye Center, and Emory senior vice provost for undergraduate education and academic affairs, and his team at the R. Howard Dobbs Jr. Ocular Immunology Lab, focus on the immune component of age-related macular degeneration (AMD), ocular cancer (melanoma and retinoblastoma) and ocular inflammation.

Santa J. Ono, PhD

Macular degeneration is the leading cause of sight impairment and blindness in older people. The macula, in the center of the retina, is the portion of the eye that allows for the perception of fine detail. AMD gradually destroys a person’s central vision, ultimately preventing reading, driving, and seeing objects clearly

In a recent article of Emory Magazine, Ono, an ocular immunologist, says, “If a person with AMD looks at graph paper, some of the lines will be wavy instead of straight. Certain parts of the image are no longer being transferred to the brain.”
