I'm a bit concerned about my privacy but the condition is herpes virus infection of the eye. The similar condition is Thygeson's disease. The drug in question (that I could not get) is called Viroptic which for some reason helps with both conditions (despite them not being related). Thygeson's is thought to be more of an immune system issue.

So if you've been diagnosed with herpes, and anti-virals don't seem to help, maybe you don't have herpes. If you do have herpes of the eye there are good drugs approved in Europe but not in the North America (though there are likely some approved drugs in the US which will still help - it's complicated).
