Concept is that the vitreous gel in the eye is like an octopus; if inject kenalog into the eye, you can't believe it sometimes when retina detached but vitreous still adherent.
Goes through the issues of cases when vitreous does not separate cleanly
See the definitive reference here from Dr Sebag:
Even if see a Weis ring, it does not really mean that they have a posterior vitreous detachment!
Next he talks about pseudo-macular holes and macular holes
Gass figured out a classification before we had the technology to help really prove it
Next he reviews retinal tears resulting from vitreous traction and talks about some other techniques aside from buckle
- Surgical, pharmacologic, or pneumatic induction of releasing vitreomacular traction
