Retinal tears develop when the vitreous pulls on the retina while retinal holes develop due to progressive thinning of the retina. Retinal holes are typically smaller and have a lower risk for causing a retinal detachment. There are some instances where retinal holes should be treated the same as retinal tears.
As we get older, the vitreous in our eyes starts to shrink and get thinner. Usually the vitreous moves around on the retina without causing problems. But the vitreous may stick to the retina and pull hard enough to tear it. When that happens, fluid can pass through the tear and lift (detach) the retina.
When the retina tears, you may suddenly see flashes of light or floaters. Sometimes blood can leak into the vitreous. This is called a vitreous hemorrhage, and it can cause a large number of floaters.
With a torn retina, fluid may leak through the hole and detach the retina. This serious problem must be treated right away or you could lose vision.
if this occurs, please call Dr. Plous right away.
