Ocular blunt trauma can cause retinal opacity in the macula and/or mid-periphery, which is known as commotio retinae. Visual impairment associated with commotio retinae often recover and most patients have favorable visual outcomes. However, cases due to severe injuries may develop permanent retinal degeneration following retinal opacity and have a poor visual prognosis. Retinal degeneration is sometimes seen as a triangular shape at various sites of the fundus.A 13-year-old boy developed a chorioretinal lesion with pigmentation extending from the optic disc to the superotemporal side in the right eye after ocular blunt trauma. The patient’s best-corrected visual acuity (BCVA) was 0.2 in the right eye. Indocyanine green angiography showed hypofluorescence from the initial phase, with a decrease of mean blur rate (MBR) on LSFG color map, which corresponded to the chorioretinal lesion.
