Abstract

Purpose:To test the validity of the geometric conclusion that 40° gaze down is optimal for pneumatic displacement of a subretinal hemorrhage (SRH) in the macula.Methods:Nine consecutive patients with SRH in the macula had an intravitreal injection of perfluorocarbon gas sufficient to cover the macula when the patient gazed down 40° below the horizontal. They were asked to maintain the gaze down position for 20 minutes every hour while awake.Results:The SRH in eight of nine patients was displaced rapidly in the first week. Visual acuity improved in seven patients. Visual recovery was limited by the presence of a subpigment epithelial component.Conclusions:Gaze 40° below the horizontal will rapidly displace a subretinal hemorrhage that is covered by a gas bubble.
