Case 1 fundus photograph of the right eye. (A) At the initial visit to the clinic, the fundus showed submacular hemorrhaging with retinal macroaneurysm in the center (arrow). (B) At 21 days after gas injection, displacement of the submacular hemorrhage was observed and the coagulum remained on the fovea (arrow). (C) At 2 months after gas injection, the submacular hemorrhage was almost totally absorbed when compared with the patient's first visit.

Ophthalmoscopy revealed subretinal hemorrhage involving the macular area with retinal macroaneurysm in the center of the hemorrhage (Figure 1A). Three weeks after gas injection, displacement of most of the submacular hemorrhage was observed (Figure 1B). Two months later, the coagulum at the macular area was almost absorbed (Figure 1C), and BCVA was 0.1.

Case 2 fundus photograph and optical coherence tomography imaging of the left eye. (A) At the initial visit to the clinic, the fundus showed submacular hemorrhaging and reddish-orange subretinal nodules corresponding to polypoidal choroidal vasculopathy (arrows). Optical coherence tomography imaging revealed a subretinal hemorrhage and elevation of the retinal pigment epithelial layer. (B) Five days after gas injection, there was displacement of the hemorrhage towards the downward region of the eye and absorbance of a part of the submacular hemorrhage. The displaced hemorrhage became coagulum. Slight vitreous haze was observed (arrows). The elevated retinal pigment epithelial layer was still observable by optical coherence tomography. (C) Two months after gas injection, the submacular hemorrhage disappeared and the vitreous haze was mostly absorbed.. Note: Optical coherence tomography revealed flattening of the retinal pigment epithelial layer at the macula.

Ophthalmoscopy revealed subretinal hemorrhage in the macular area and reddish-orange subretinal nodules corresponding to polypoidal choroidal vasculopathy (Figure 2A). A slight vitreous haze was observed (Figure 2B). At 2 months after the initial gas injection, submacular hemorrhage disappeared and vitreous haze was also absorbed (Figure 2C).
