 Occlusion is a method that has been used in the treatment of amblyopia since before and CAM visual stimulation (CAM therapy) is other method which can be used for amblyotherapy.In this study twenty two 6-year-old, previously untreated amblyopic children were divided into two subgroups with regard to anisometropic and ametropic amounts.The first group was treated by occlusion therapy and the second group was treated by CAM method. These two methods were compared in improving visual acuity,accommodation, ocular movement(saccades-pursuits)and stereoacuity.

  We found that CAM therapy was significantly more effective and better than occlusion in improving visual acuity and stereoacuity.There was significantly no difference between two method in improving amplitude of accommodation. However occlusion therapy was significantly more effective than CAM therapy in improving accommodative facility and saccadic and pursuit movement.

  It is concluded that CAM therapy is valuable method in the treatment of anisometropic amblyopia, however it is not a complete method and must be used with occlusion.
