4.Conclusion The astigmatic degrees that can bring about ametropia amblyopia are as follows the simple myopia astigmatism of 1.62±0.52D,the simple hyperopia astigmatism of 1.53±0.48D and the irregular degree of astigmatism of 1.28±0.33D. The lowest sphere and colum mirror degree of the compound hyperopia,myopia and mix astigmatism are all 0.5-1.0D to cause ametropia amblyopia.
6.5. Diopter difference of three group before and after cycloplegic refraction, was same in hyperopia, which of Romi eyedrop group was smaller less than 0. 25 D compared with 1% Atropine group in myopia. Conclusions
