My child has ocular migraines and I need help?

My son has been complaining of visual disturbances for quite awhile so 'I took him into the doctor and she said he has ocular migraines. I have migraines with aura but have horrible pain, he has no pain. She said she would refer him to an ophthalmologist but I don't know what to do so if anyone has experience with these please help me with any advice. Thanks
