Objective: To investigate the expression of GAP-43 in the lateral geniculatenucleus and the visual cortex area 17 of monocularly deprived rats during the critical period, to understand the mechanism and seek out effective methods for preventing and treating deprived amblyopia during the development period. The study will offer a reference basis to prevent and treat amblyopia of deprivation among children.

Material and methods1.select of case: to choose 158 patients who wear followed up from 1988 to 2002 after operation. All patients were diagnosed as MG, and treated with same medical cure during period of preoperation and post operation. 2.Collectionofdata:.To collect all data through designing a uniform follow-up table for thymectomized patients ,and to analysis the effect of factors including age, gender, disease duration of preoperation, clinic types and pathological types to prognosis at three follow-up period?
