Eye Exercises Might Boost Fine Depth Perception – Thu Oct 14, 11:48 pm ET THURSDAY, Oct. 14 (HealthDay News) -- A new study says a push-pull training method is a good way to correct a condition called sensory eye dominance, in which an imbalance between the vision strength of the eyes impairs fine depth perception. This method -- which involves making the weaker eye work while the stronger eye is suppressed -- could be especially important for people who depend on fine depth perception for their work, such as dentists, surgeons, machinists and athletes. It's also likely that the method can be adapted for treating children with amblyopia (also known as lazy eye), which affects 2 to 3 percent of children in the United States, said the authors of the study published in the Oct. 14 online edition of the journal Current Biology. "After a 10-day training period, we found our participants' sensory eye dominance is significantly reduced as the two eyes become more balanced. As a consequence, their depth perception also improves significantly," Teng Leng Ooi, of Pennsylvania College of Optometry at Salus University, said in a news release from the journal's publisher. It's not clear how the push-pull training method works to readjust the balance between the eyes, the study authors noted. "Possibly, by causing the strong eye to be suppressed at all times during the training, we reduce the inhibitory hold of the strong eye on the weak eye," Ooi said. Further studies are needed to determine exactly how this eye training technique improves depth perception, the study authors suggested. Êîëëåãè, Âû ÷òî-íèáóäü ÷èòàëè ïðî ýòî? |

Teng Leng OoiMuch knowledge of sensory cortical plasticity is gleaned from perceptual learning studies that improve visual performance [1-7]. Although the improvements are likely caused by modifications of excitatory and inhibitory neural networks, most studies were not primarily designed to differentiate their relative contributions. Here we designed a novel push-pull training protocol to reduce sensory eye dominance (SED), a condition that is mainly caused by unbalanced interocular inhibition [8-10]. During the training, an attention cue presented to the weak eye precedes the binocular competitive stimulation. The cue stimulates the weak eye (push) while causing interocular inhibition of the strong eye (pull). We found that this push-pull protocol reduces SED (shifts the balance toward the weak eye) and improves stereopsis more so than the push-only protocol, which solely stimulates the weak eye without inhibiting the strong eye. The stronger learning effect with the push-pull training than the push-only training underscores the crucial involvement of a putative inhibitory mechanism in sensory plasticity. The design principle of the push-pull protocol can potentially lend itself as an effective, noninvasive treatment of amblyopia.
