[In vivo high-resolution imaging of rat retina with optical coherence tomography and the expression of Bcl-2, Bax, Caspase-3 mRNA during critical period plasticity].

Objective: To observe the changes of retinal thickness during critical period plasticity in rat, and to investigate whether apoptosis participates in the structural forming of retina.

Methods: Experimental research. 50 normal newborn pups of SD rat were randomly selected in the experiment.
