—In their article, Lewen et al1 stated that circumferentially oriented scleral buckles predispose to the formation of arcuate retinal folds following intravitreal gas injection by creating redundant retinal tissue. They believe that radially oriented buckles do not cause redundant retinal tissue and, hence, are less likely to be associated with such folds. Three years ago I described an eye in which a posterior arcuate retinal fold developed after a fishmouthed tear was flattened with intravitreal air.2 As in the three patients described by Lewen et al, the tear overlaid a circumferentially oriented buckle. While this initial experience supported the authors' inference that a circumferential buckle is necessary for arcuate fold formation, the results of subsequent operations did not.Our first patient presented with a superior detachment that extended into the macula. The detachment was secondary to a horseshoe tear at the 12-o'clock meridian. When a
