Badly destroyed retina?

OK so last year I had a bad accident that lead to infection that almost claimed my eye. After a few months the infection destroyed my retina to the point where I may never get 20/20 vision back. I'm afraid to travel because I'm afraid of getting another infection... does anyone else have the same issue? If so can you please share your experience? I want to get my hope back that maybe one day I can see again... Feel free to go anon if you want...
