For The Last Three Days, My Vision In My Right

for the last three days, my vision in my right eye has been getting very blurry and I feel constant pressure in my eye. It seems to be getting worse as time goes. I had lasik 6 months ago and it's never been perfect but the last 3 days have been the worst. I read something online about spider web and how that could be my retina detatching with my vision being this bad in a short period of time. Is this an emergency?
