Digital glasses to treat 'lazy eye' in kids

    New programmable electronic glasses can help improve vision in children just as well as the more traditional treatment using eye patches, according to results from the first US trial of the device.

    Digital glasses to treat 'lazy eye' in kids

    This "digital patch" is the first new effective treatment for lazy eye in half a century, researchers from the Glick Eye Institute at Indiana University said. Lazy eye, also called amblyopia, remains the most common cause of visual impairment in children.

    Amblyopia is poor vision in an eye that did not develop normally during early childhood. This can occur when one eye is much more nearsighted than the other, or when one eye wanders or strays inward. The child needs to receive treatment by the age of 8 or so while their eyes and brain are still developing, or he or she could become blind in the weaker eye.

    A recent study found that 1 in 4 kids feel anxiety before using eye drops. Nearly 15 per cent refuse to take eye drops at all. Both drops and eye patches work based on the occlusion method. This blocks vision in the eye with the best sight, forcing the brain to rely on the so-called lazy eye.

    During the process, vision improves though many children will still need glasses to correct their eyesight. In comparison, the electronic glasses used in the study combine vision correction and occlusion. The lenses can be filled to a child's vision prescription.

    Because the lenses are liquid crystal display (LCD), they can also be programmed to turn opaque, occluding vision in the left or right eye for different time intervals, acting like a digital patch that flickers on and off. Researchers recently tested the effectiveness of occlusion glasses compared to patching in a randomised clinical study.

    They recruited 33 subjects with lazy eye between age 3 and 8 who wore spectacles to correct their vision. One group wore an adhesive patch for two hours daily. The other wore Amblyz occlusion glasses for 4 hours daily.

    In the study, the lens over the eye with better vision switched from clear to opaque every 30 seconds. After three months, both groups of children showed the same amount of improvement in the lazy eye, gaining two lines on a reading chart.

    "When you talk to adults who underwent childhood treatment for amblyopia, they will tell you that wearing a patch was the worst thing ever," said Daniel Neely, a paediatric ophthalmology professor at Indiana University who led the study.

    "With these electronic occlusion glasses, the child learns that the lens will be clear again in just a few seconds so they may be more cooperative with the treatment. For parents who have struggled with drops and patching, this could be a great alternative," said Neely.
