Study Details

Brief summary:

This is a randomized controlled trial comparing displacement of macula and the rapidity of reattachment of macula between two different positioning techniques after pneumatic retinopexy : Direct technique (patient is positioned so that the bubble is immediately placed directly over the retina break) and Steamroller technique (patient is initially positioned face down for 4-6 hours and subsequently changes their head position so that the bubble is then placed directly over the retina break).
