Horizontal scan of a B-scan ultrasonography image of intravitreal gas and choroid elevation with the patient seated on postoperative Day 7. Because of the reflection of the intravitreal gas (dotted outline), B-scan ultrasonography could not image the choroidal elevation, which developed superior to the ocular fundus.

On postoperative Day 7, a CT scan showed two separate low-density areas, which confirmed the presence of suprachoroidal gas; the gas was not visible on B-scan ultrasonography (Figure 1) because of the presence of intravitreal gas (Figure 2A-C).
CT scans showing the presence of suprachoroidal gas. (A-C) On postoperative Day 7, two separate low-density areas of suprachoroidal gas (arrows) and intravitreal gas (arrowheads) are seen. (D-F) On postoperative Day 14, the intravitreal gas has resolved and a small amount of residual suprachoroidal gas is seen (arrowheads).. Abbreviation: CT, computed tomography.

On postoperative Day 7, a CT scan showed two separate low-density areas, which confirmed the presence of suprachoroidal gas; the gas was not visible on B-scan ultrasonography (Figure 1) because of the presence of intravitreal gas (Figure 2A-C). By postoperative Day 14, the intravitreal gas had resolved and the CT scans showed a small amount of residual suprachoroidal gas (Figure 2D-F); further, the headache had resolved completely, and visual acuity was 20/20.
(A) Color fundus photograph of suprachoroidal gas. On postoperative Day 10, a large, temporo-superior choroidal elevation (arrowheads) is seen and the intravitreal gas (arrow) occupies <10% of the vitreous cavity. (B) The retina is attached, and 8 months later, the visual acuity is 20/20. The choroidal folds (arrowheads) persist long after the suprachoroidal gas has resolved.

On postoperative Day 10, the intravitreal gas filled <10% of the vitreous cavity and the suprachoroidal gas started to diminish (Figure 3A). The retina was attached and, 8 months later, visual acuity was 20/20 (Figure 3B).
