Application of guanylate cyclase inhibitor to preparation of medicament for inhibiting myopia

The invention relates to a preparation method of a medicament for delaying and inhibiting myopia, in particular to the application of a guanylate cyclase inhibitor for the preparation of a medicament for inhibiting myopia. The guanylate cyclase inhibitor serves as the myopia-inhibiting medicament to reduce the content of cGMP (guanosine-3',5'-cyclized-phosphate, cyclic guanosine monophosphate) and then, can inhibit the formation of animal experimental myopia.
