Children in Amblyopia Study Receive Free Glasses as Doctors Determine Connectivity between the Retina and Brain
LEWISVILLE, TEXAS, (July, 2012) Imagine if you’re looking at a movie screen but one of your eyes sees the screen as if it is ten feet away and the other eye sees the screen at five feet away, and then your brain has to figure out how to fuse these two different image sizes. That condition is known as aniseikonia. Aniseikonia has long been suggested to occur when an individual’s eyes are different lengths, such as when a child has one good eye and one very far- or near-sighted eye. Aniseikonia may also be a factor that limits treatment success in children with amblyopia
The interesting thing about aniseikonia is that it is unknown if aniseikonia exists in children even when they have one long eye and one short eye. It may be that the child takes the two different retinal images and makes the adjustment once the images hit the brain. Studying the existence of aniseikonia in kids with equal eyes and unequal eyes is the work of Lori Ann Kehler, OD, FAAO, Vanderbilt University, and Katherine K. Weise, OD, MBA, FAAO, University of Alabama at Birmingham School of Optometry along with eight other investigators from Nationwide Children’s Hospital in Ohio, and schools of optometry in Indiana, California, and Illinois. For the study, children with two normal-sized eyes are the control, and children with one normal eye and one longer or shorter eye with either unequal or equal vision between the eyes are in the test group
The point of the study then becomes two fold: First, if the condition is not a factor in kids, then Eye Care Professionals do not have to spend time trying to minimize with custom-made glasses. Second, if the condition exists, then ECPS can look at aniseikonia as a potential predictor for lazy eye treatment success and the best possible solutions.
“So many of us go into optometry so we can see the look on someone’s face when we fit them with glasses and they see properly for the first time. It is especially rewarding when working with children,” said Dr. Weise. She continued, “The exciting thing about being in research and this study in particular is that we may be able to learn something that will help replicate that smile thousands of times over.”
HOYA Territory Sales Manager Randy Snuggs saw Dr. Weise give a presentation last year and he was inspired to put the pieces together along with HOYA’s Director of Professional Affairs, Dr. Gregory Hicks. In short, children age 5 to 12 will go to one of the six clinics participating in the study and an assessment will take place to decide if they are eligible. If eligible, they will receive a full eye exam and testing for the study. Ensuring all the participants had access to the same quality eyewear at no cost, HOYA single vision Phoenix lenses with EX3, helps keep the results consistent. These shatter-resistant lenses that minimize aberrations and glare may be particularly for kids with lazy eye. Frames are being provided by A&A Optical and all jobs are running through the HOYA Dallas lab. The study will continue throughout 2012 and Dr. Weise looks forward to publishing the results when they become available.
