Many retinal tears are spontaneous, though some factors can play a role in the probability of the condition occurring in some individuals. The majority of retinal tears occur this way.Īside from this spontaneous occurrence, retinal tears can also happen due to trauma or following an eye surgery, such as a vitrectomy or cataract removal. When this happens, it can cause a spontaneous tear in the retina. However, some people have a more “sticky” vitreous, causing the vitreous to tug on the retina as it separates. This process is known as posterior vitreous detachment (PVD), and typically doesn’t cause any serious problems. The vitreous is attached to the retina at birth but detaches as the body ages. The vitreous is the gel-like substance that fills the large chamber in the back of the eye (between the lens and the retina).
