Although it is not a life threatening illness, sinusitis can become very annoying and maybe even lethal if it is not treated quickly and properly. Thankfully, nobody has completely lost their eyesight because of sinusitis. However you should still treat the condition seriously so the vision does not worsen even more. More importantly, don't wait for signs. Treat it immediately if you think you have sinusitis as later on the problems could escalate.
