- This 50-year-old woman accidentally hit her right eye with a metal tube. The next day she first noticed symptoms of this retinal detachment, which was caused by this usually long and narrow horseshoe tear. Note the rolled edges on each side of the tear and the long blood vessel running down the length of the flap. This illustrates the rule that when traction is exerted on the retina, the retinal blood vessels have a relative resistance to tearing and are the last areas to rupture.
