This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

(1) To evaluate the impact of occlusion therapy on the outcome of treatment for stimulus deprivation amblyopia.
(2) To establish realistic treatment outcomes.
(3) To examine existing evidence in order to establish the dose/response effect for conventional occlusion in stimulus deprivation amblyopia.
(4) To assess the effect of the duration and density of the amblyopia on the outcome.
(5) To assess the impact of the causative factor on the size and direction of effect.
