摘　　要：AIM:To evaluate the visual outcomes of standard amblyopic treatment add-on training via perceptual learning in refractive amblyopic children and to identify the risk factors for treatment failure.METHODS:Retrospective charts were reviewed in children with refractive amblyopia who received standard treatment and add-on Cambridge Visual Stimulator(CAM)training.The add-on CAM group that was enrolled had worn full-corrected glasses for at least 2mo before training.A control group received only the standard treatment.Treatment success was defined as best-corrected visual acuity(BCVA)≥20/25.The age,sex,initial BCVA,refractive errors,sessions and duration of training,and final BCVA were recorded.RESULTS:A total of 209 children(129 children in add-on CAM group and 80 children in control group)were enrolled.Seventy-six percent of unilateral and 87%of bilateral amblyopic children achieved treatment success.In children with unilateral or bilateral moderate amblyopia,the duration to reach BCVA≥20/25 was significantly shorter in add-on CAM group than in control group.Poor initial BCVA(P<0.001)and high astigmatism(P=0.007)were risk factors for treatment failure after add-on CAM training.Age,sex,and types of refractive error were not associated with treatment success.CONCLUSION:Add-on CAM training is an effective strategy for visual improvement and can shorten the treatment course when the effect of standard treatment is limited in amblyopic children.
