Abstract
To the Editor. —This interesting complication was described by Yeo and colleagues1 in the August 1986 Archives. The authors reported a case of extramacular retinal detachment that was treated with pneumatic retinopexy. Immediately after the injection of the gas bubble they noted that the detachment spread into the macula. The retina was reattached the next day and there was no loss of visual acuity. We have not observed this complication.2,3 Twelve of our first 100 patients had extramacular detachments very near the fovea. There were no apparent complications and in all 12 eyes the level of good preoperative visual acuity was preserved. We believe that the complication of macular detachment can be prevented with the use of what we call the "steamroller" technique. With this technique the patient is placed face down immediately after gas injection. This positions the gas bubble at the macula and immediately pushes the
