a Hypopyon and corneal infiltration were both absent 3 weeks after the surgery. (b and c) Vitreous opacity was largely absent on B-scan ultrasonography, and the full-field ERG waveform acquired at the same time had no amplitude reduction or latency delay. d Although mild vitreous opacity was confirmed on ultrasonography 4 days after tocilizumab infusion, it spontaneously improved. e and f There were no signs of infection relapse in the slit-lamp examination, and no vitreous opacity on B-scan ultrasonography 4 months after the surgery
