Purpose: To report the time course of choroidal blood flow (CBF) in a commotio retinae case using laser speckle flowgraphy (LSFG). Observations: A 58-year-old Japanese man with complaints of worsening left visual acuity after blunt eye trauma was diagnosed with commotio retinae. A funduscopic examination showed macular opacity, and LSFG results demonstrated CBF impairment in the affected eye. Optical coherence tomography also showed disruption of the photoreceptor outer segment. Seven months after the initial visit, CBF was significantly increased, along with improvement in the photoreceptor outer segment. Conclusion: and importance: We revealed CBF impairment in a case of commotio retinae for the first time. CBF impairment may be involved in the pathogenesis of commotio retinae, and LSFG may be useful for examining CBF in commotio retinae.
