This 54YO female presented with a giant retinal tear with macula-on rhegmatogenous retinal detachment.
At vitrectomy several hours later, the tear was found to extend for 190 degrees.
Learning Points:
By definition, giant retinal tears extend at least 3 clock hours. Surgical repair can be greatly facilitated by using Perfluoron (PFO), a heavier-than-water liquid that helps unroll the giant tear and prevents posterior retinal slippage.
