Role of Acupuncture in Amblyopia Treatment.

Amblyopia is an ophthalmological developmental disorder that occurs during early childhood due to disrupted binocular vision. It leads to reduced best-corrected visual acuity in one eye (seldom in both eyes) in which the visual acuity of one eye is 2 rows weaker than the other eye on a Snellen vision testing chart. Many studies have reported the outcomes of acupuncture in the treatment of amblyopia. Evidence suggests that acupuncture improves outcomes in children with amblyopia, but these studies are associated with several limitations which may affect the evaluation of the efficacy and reproducibility of studies on acupuncture. One important limitation is the lack of sham acupuncture as a control which has not been used in any clinical trial. The use of nonacupoint acupuncture is suggested as a placebo to improve the quality of evidence and comparability?
