Advantages:

Low vacuum setting might reduce the rate of retinal tears and/or retinal detachment after macular surgery. Traction on the peripheral retina during vitrectomy increases with the maximum vacuum set up. The aim of our study was to precise the incidence of retinal tears and retinal detachment after macular surgery depending on the maximum vacuum set up during the surgery.

Methods:

Retrospective comparative study between group G400 including 1432 eyes of the consecutive patients operated on epiretinal membrane or macular hole, with maximum vacuum set at 400 mm Hg, and group G230 including 434 eyes of the consecutive patients operated on with maximum vacuum set at 230mm Hg. All patients were operated by 2 experimented surgeons between November 2000 through June 2010.

Effectiveness / Safety:

The incidence of retinal breaks was 5,1% in group G400 versus 3% in group G230.
