An otherwise healthy 13-year-old Japanese boy presented with reduced central vision in his left eye, 3 days after suffering a blunt trauma from being hit by a fishing sinker. Assessment of BCVA showed only the ability to perceive hand motions in the left eye compared to 20/13.3 in the right eye. The intraocular pressure was 8 mmHg in both eyes. The anterior segment of the left eye showed hyphema and laceration of the bulbar conjunctiva. No traumatic cataract or rupture of the globe was seen. Fundus examination of the left eye showed a subretinal hemorrhage extending from the posterior pole to the inferior midperiphery and a slight vitreous hemorrhage (Fig. ). No retinal tear or retinal detachment was seen. In contrast, the right eye appeared normal. Swept-source optical coherence tomography (OCT; DRI OCT-1 Atlantis, Topcon Medical Systems, Tokyo, Japan) showed the presence of a thick submacular hemorrhage in the left eye (Fig. ). Attempts to measure the retinal sensitivity using a microperimeter (MAIA; CenterVue, Padova, Italy) failed, as it was below the detection limits of the instrument (Fig. ). We therefore diagnosed submacular hemorrhage in the left eye, due to choroidal rupture following blunt trauma.\nTwo days after the initial visit, we carried out anterior chamber lavage, vitrectomy, subretinal injection of rt-PA (GRTPA®, Mitsubishi Tanabe Pharma Corporation, Japan) and air tamponade on the left eye under general anesthesia. This operation was performed using the methods reported by Kimura et al. []. Briefly, after performing a 25-gauge micro-incision vitrectomy, 4,000 IU rt-PA in 0.1 ml was injected subretinally using a 38-gauge subretinal infusion needle (MedOne, Sarasota, FL) to liquefy the submacular hemorrhage. Before completing the operation, fluid-air exchange was performed. The patients remained facedown for 3 days after surgery to displace the submacular hemorrhage. The day after the operation, most of the submacular hemorrhage had moved to the inferior periphery.\nOne month after the operation, the BCVA of left eye was 20/1000 and we observed cataract formation, thin remnants of the submacular hemorrhage and juxtafoveal choroidal rupture (Fig. ). We then carried out phacoemulsification and aspiration, intraocular lens implantation and intravitreal injection of 0.05 ml bevacizumab (Avastin®, Hoffmann-la Roche, Basel, Switzerland) in the left eye under general anesthesia. Two months after the second operation, the submacular hemorrhage had totally disappeared (Fig. ) and the BCVA in the left eye had improved to 20/40. As shown in Fig. , the retinal sensitivity had markedly improved.
A 13-year-old boy presented with 5 months old injury to the left eye. Examination of the left eye showed iris sphincter tears with angle recession. A curvilinear stellate yellowish gray lesion was seen just nasal to the fovea with associated gray-white lesion at the fovea []. The right eye was normal.\nSSOCT showed hyper-reflective, disorganized tissue involving RPE/BM complex, ellipsoid layer, external limiting membrane (ELM), and outer nuclear layer. This presumed scar tissue also involved the choriocapillary layer and the Sattler's layer. The Haller's layer was only minimally involved []. Scar tissue was also seen extending on the surface of the RPE away from the presumed site of rupture. The yellowish gray lesion seen at the posterior pole seemed to correspond to the areas where OCT showed the hyper-reflective scar tissue. No evidence of a full thickness BM or choroidal discontinuity could be made out.\nOCT angiogram (OCTA) showed the inner retinal capillaries to be intact. The outer retinal capillary layer showed some decreased vascular marking in the area of the scar. At the level of the photoreceptor and RPE, there was a discontinuity in the tissue pattern corresponding to the scar. Surrounding this discontinuity, there were new vessels. At the level of the choriocapillaries besides discontinuity in the vascular pattern due to scar tissue, there seemed to be increased vascularity along the rupture site itself [].
