Congratulations to Ying Li, MD, PhD, 3rd place winner of the Best Image contest held as part of the Emory Postdoctoral Research Symposium, which takes place next week (Thursday, May 19). Li is in Eldon Geisert’s lab, and provided Lab Land this description:
“Like a benevolent overseer of the cosmos, the epicenter of the optic nerve appears to extend a axon reassuringly to the small, seemingly lowly single ganglion cell, reminding us that every cell matters.”
Was your mother right when she told you not to read in dim light? Is there a correlation between your love of reading as a child and the fact that you now need glasses for distant objects?
These questions and more are being addressed by researchers at Emory and the Veterans Administration.
In a lab at the Atlanta Veterans Affairs Medical Center near Emory, researcher Machelle Pardue, PhD, who has an appointment at Emory Eye Center, studies why some eyes seem to change over time, growing larger and longer, thereby making that eye what we call â€œnearsighted.â€ This dependence on glasses or contact lenses to see distant objects seems to be a growing phenomenon. Scientists and ophthalmologists call this nearsightedness myopia, and whether itâ€™s environmental or geneticâ€”or a likely combination of bothâ€”is fascinating to Pardue and her research colleagues.

The unique collaborative nature of Pardueâ€™s work draws on the talents of many specialistsâ€”clinical, engineering, molecular, and imaging. Her ongoing work and the work of others who serve both at the VA and Emory will no doubt lead to important findings and from that, possible clinical treatments.
For more information about Pardueâ€™s work, read the feature article Â â€œClosing in on myopiaâ€”and moreâ€ in Emory Eye magazine, summer 2010, page 8.

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.

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 itâ€”wearing her glasses for school and playtime, donning a scuba mask at the beachâ€”but it doesnâ€™t limit her choices.
Following her interests, Emilia has earned a gold belt in karate. Sheâ€™s learning gymnastics. She swims. She loves to romp with Daisy, her black cocker spaniel. And while most people donâ€™t even notice that one of this little girlâ€™s shining dark-brown eyes is different from the other, Emilia shares her story with a few. â€œI tell my teachers and my friends that I have a special eye,â€ she says.
