Well, of course, retinal detachment can lead to blindness. And it is a kind of disease which can be very dangerous. Generally speaking, retinal detachment can be caused by many factors, such as the eye pressures, and injury. And for your situation, I will suggest you should take the retinal detachment surgery quickly, or it can lead to blindness. Also, it is important for you to be careful after the surgery, for your eyes are sensitive and fragile. For example, you should avoid eye injuries by wearing a protective shield at night and with naps until you are advised by your doctor. Anyway, just go and see an eye doctor as soon as possible.
