my dad is in rentinitis pigmentosa for over 30 years and his vision drepress a lot recently, but we are in China. i found an article about the eye drop rescula, but unfortunatly it's not for sale in China, and all the online pharmacys need prescription from north America.
here's what i want to know:
1. is there any online hosipital to have a long-distance diagnose and prescription?
2. if we go to America to see a doctor, the priscription can only use once or for long term?
