I had 2 tablets of 5mg Teva Prednisone or 5 days. Today my eye doctor said that my eye pressure is high. Is it because of this medicine?

Unlikely. High pressure inside the eye is caused by an imbalance in the production and drainage of fluid in the eye. It's somewhat unlikely (although not impossible) that 10 mg of prednisone caused this. Attached is a good article which explains intraocular hypertension at length. Hope it helps! http://www.emedicinehealth.com/script/main/mobileart-emh.asp?articlekey=59078&page=1.
