How high risk of posterior vitreous detachment will develop to the retinal tear?

Have you experienced or seen others having posterior vitreous detachment (PVD) developed to the retinal tear and what were the symptoms?

I did experience this. My posterior vitreous detachment (PVD) eventually developed into a retinal tear. The first symptom I noticed was a flashing light whenever I moved my eyes side to side. It turned out that I needed laser surgery to stop the tear from getting bigger. The procedure worked to secure the retina, but the floater that came with the PVD never went away — it’s very aggravating.
