In a July 2012 interview published by the Sydney Morning Herald newspaper, Chen Zhangho, the lead doctor for the Chinese Olympic team at the Los Angeles , Seoul and Barcelona Olympics told of how he had tested hormones, blood doping and steroids on about fifty elite athletes.  Chen also accused the United States, the Soviet Union and France of using performance-enhancing drugs at the same time as China.  Chen also blamed foreign experts for "lying" to the Chinese about the effectiveness of doping, saying he and others "blindly believed them like fools".  The Chinese officials eventually concluded that training was the key to performance and that taking drugs did not guarantee this. 
The point is (and all the others who have responded to you already have emphasized this), it is very clear that you need the help of those who deal with difficult uveitis cases day in and day out (link to list of uveitis specialists). Unfortunately, it appears that you must be prepared to travel to get the help of such a person. But do it you must; and the consultant whom you choose will undoubtedly want to see you again, too. But he or she will also want to work with an ophthalmologist and perhaps a second specialist (., a rheumatologist or a hematologist) in an effort to give to you the care that you need to preserve the vision you have, and hopefully to get back at least a little of what you have lost.
Sustanon 250 (Organon) is pretty readily available OTC. Not every pharmacy will have it, and not every pharmacy will stock more than a few ampules, but both in Saigon and Hanoi it hasn't been hard to find. Proviron is also reasonably readily available. You can find Andriol Testocaps very easily as well, but they're expensive. Deca is also avbailable, but with a low concentration (50/amp) so you'd be pinning a heck of a lot to get anywhere with that. Some websites for some Vietnamese pharmacies list other testosterone products, (prop, enth) and anavar, but I've never managed to find any that actually stock it, even visiting a big medicine market where all the pharmacies themselves purchase their supplies.
