A 15-year-old girl presented with blurred vision after being hit by an elbow on her left eye. Her best-corrected visual acuity (BCVA) was 16/20. On fundus examination, both a choroidal rupture that formed a crescent shape concentric to the optic disc and a subretinal hemorrhage were detected (fig. ). Optical coherence tomography (OCT) showed that the juxtafoveal retinal pigment epithelial layer with Bruch's membrane was disrupted, and the inner segment/outer segment (IS/OS) of the photoreceptor junction and the external limiting membrane (ELM) layer were distorted with suspected pinpoint disruption (fig. ).\nAfter 3 weeks, her visual acuity reduced to counting fingers. Fundus examination revealed that the subretinal hemorrhage had absorbed and the choroidal rupture had expanded. The crescent-shaped window defect including the fovea was observed on fluorescein angiography (FAG) (fig. ). Wider disrupted layers of the RPE, the IS/OS junction, and the ELM at the corresponding area were detected in OCT. When compared with the first medical examination after the injury, the IS/OS junction and the RPE adjacent to the ruptured site were hardly distinguishable, although they were originally clearly observed (fig. ).\nSteroid pulse therapy (methylprednisolone 500 mg intravenous for 3 days and prednisolone 30 mg oral, tapering for 11 days) was started in another hospital, and 3 months after the injury, visual acuity increased to 20/125. Five months later, OCT revealed that the size of the expanded choroidal rupture had reduced, and the adjacent retina had improved sufficiently to distinguish the IS/OS junction and the RPE. However, FAG disclosed a choroidal neovascular membrane originating from the nasal edge of the choroidal rupture (fig. , fig. ). An intravitreal bevacizumab (Avastin, 1.25 mg/0.05 ml; Genentech, Inc., San Francisco, Calif., USA) injection was administered, and 1 month later, the patient's BCVA of the left eye had improved to 20/32, and the CNV had shrunk (fig. , fig. ). Also the IS/OS junction and the RPE had improved sufficiently and were able to be distinguished (fig. ).
A 46-year-old male army colonel sustained blunt injury to the right eye following direct contact with a tennis ball to the closed eyelid. Three hours later, visual acuity was 20/30 in the right eye and 20/20 in the left eye with central corneal abrasion, mild anterior chamber cells, flare, and a localized gray-white oval discoloration in the macula of the right eye. Topical corticosteroid ointment and systemic corticosteroid (50 mg prednisone daily for 5 days) were started. At 20 h following trauma, high-definition SD-OCT and OCTA were obtained through clear cornea.
