—Subretinal gas as a complication of pneumatic retinopexy has recently been reported.1 The subretinal gas may prohibit a retinal tear from flattening against the underlying pigment epithelium, eventuating in persistent or increasing retinal detachment. A retinal detachment complicated by subretinal gas may be managed successfully by scleral buckling techniques.
Report of a Case.
—A 63-year-old man was referred to the retina service with a single flap tear in preequatorial retina at the 1:30 position of the right eye. A 60° subclinical retinal detachment surrounded the retinal break. Visual acuity in the affected eye was 20/25 with full myopic correction of −4.5 diopters. We attempted pneumatic retinopexy using room air as the internal tamponade. We injected 0.75 mL of room air intravitreally by the method described by Hilton and Grizzard.2 Anterior chamber paracentesis lowered the intraocular pressure to 20 mm Hg. We observed a single air
