As a pediatric ophthalmologist, I do my best to assure that every young patient I examine will have a lifetime of perfect sight. The condition that I battle most commonly is amblyopia, or “lazy eye,” in which the eye is healthy but does not develop vision — simply because the brain doesn’t receive proper input when a child’s visual system is “learning” how to see.
When I can diagnose amblyopia early enough, I can treat it with an eye patch or eye drops to block the “good” eye, giving the eye with amblyopia time to catch up. But amblyopia does not fight fairly: about half of affected kids have no visible signs of the condition. As a result, amblyopia silently steals the sight of hundreds of thousands of children — many of whom will never get their vision back because treatment started too late.
In a series of 17 short TED-style talks next Tuesday, February 14, clinicians and scientists from Children’s will present new products, processes and technologies to make health care safer, better and less expensive. The event, from 1-5 p.m. Eastern, is sponsored by the Innovation Acceleration Program. It’s now running a wait list, but you can also watch the live stream or track the proceedings on Twitter (#iDay) or via @science4care. Here’s a small sampling of next week’s presenters; for details, read the press release or view the full agenda.
Diagnosing lazy eye when it’s most treatable: in preschoolers
If lazy eye, or amblyopia, is caught early – ideally, before age 5 – it’s easily treated by patching the “good” eye, forcing the child to use and strengthen the weaker eye. But if it goes unnoticed, the weak, unused eye can slowly go blind, …
Children with “lazy eye,” or amblyopia, have structurally intact eyes that may appear normal. But one eye isn’t used, generally because of a subtle misalignment. Unless someone notices this early enough, the “lazy” eye can slowly go blind, simply because the brain hasn’t received proper stimulation from it. It’s learned to ignore input from that eye.
“While amblyopia is easy to treat if you get to the kids early, it’s hard for us as ophthalmologists to get to the kids early because often the condition isn’t detected in the pediatric office,” says David Hunter, chief of ophthalmology at Children’s Hospital Boston.
Treatment consists of patching the sound eye, forcing the child to use the weaker eye. Ideally, this should be started before age 5, when the brain is still able to relearn; once a child reaches 8 to 10 years it’s often too late to restore his vision. …
When my parents told me I should walk around with my right eye patched like a pirate—on regular days, not just Halloween—I wondered if they were joking. They weren’t: those really were the doctor’s orders.
As a child, I had amblyopia, or “lazy eye”: my left eye had much poorer vision than my right eye. The eye itself was fine, but my brain wasn’t processing information coming from it. The plan was, by patching the “good” eye, to force my brain to use inputs from the amblyopic eye. …
