Will I pass glaucoma to my children?

 Hi I'm 30 this year and I'm planning to marry my girlfriend next year. Although she doesn't mind the fact that I have glaucoma and the possibility of me going blind one day, she is reluctant to have my children because she's afraid they will have glaucoma too. 

Is there any way we can find out if I will pass glaucoma on to my children? What are the odds of that happening?
