Eye position stability in amblyopia and in normal binocular vision
Investigative Ophthalmology & Visual Science, 07/16/2012
Exclusive author commentary
Gonzalez EG et al. – Deficits in spatiotemporal vision in amblyopia are associated with poor position stability (PS). PS of amblyopic and fellow eyes is differentially affected depending on viewing condition.
Esther G Gonzalez (07/17/2012) comments:
The data showed decreased fixation stability in the amblyopic eye during binocular and monocular viewing. The fellow eye’s position stability is comparable to controls during binocular and monocular viewing, but in open-loop testing (i.e., when the eye is behind an opaque patch) it is comparable to the amblyopic eye’s. The poor position stability exhibited by the amblyopic eye when it is behind an opaque patch shows that the ocular motor control from the fellow eye is not as good as what is seen in normal controls.
