Retinal Tear
Symptoms of a retinal tear are a sudden new onset of floaters, which are actually blood cells that float around in the vitreous. There are not usually physical symptoms or pain involved with developing a retinal tear. Typically there are no visual symptoms with a retinal tear other than seeing new floaters or eye flashes of light.
A tear must be treated quickly by applying a heat sealing laser or cold therapy (cryotherapy) around the tear to wall off any further peeling of the retina. This is a non-invasive office procedure that is performed to insure the tear does not turn into a retinal detachment. Although a retinal tear itself is not blinding, if you do not treat a tear quickly it can turn into a retinal detachment which requires surgery and can result in permanent visual loss.
