- In this 54-year-old woman, lattice degeneration has led to a large horseshoe tractional tear around the posterior side on one end of the lesion resulting in a clinical retinal detachment. Note the very attenuated blood column passing through the white sheath vessel that crosses the tear. This demonstrates that the white blood vessels and a fragment of attached tissue are the only structures which have escaped the tearing effect of the strong vitreoretinal traction which occurred. This usually is true, although, in some cases this bridging vessel may bleed.
