Australian Shepherds Blue eye and Glaucoma

We have had "Emergency February 2017"
This year our Australian Shepherds eye turned cloudy and started swelling. Trips to the vet and off to Denver for an emergency eye exam; the conclusion is Glaucoma. 
So whether or not it will help, In addition to the medications from her growing list of Doctors, we are trying a diffuser.
She has been on her medications and eye drops for a week now and there is some improvement but she is not 100%
Essential Oils I am trying will include Copaiba & Ledum from Young Living.
