Slit-lamp examination, retinal fundus, and B-scan ultrasound images. A-C, slit-lamp examination (A), retinal fundus (B), and B-scan ultrasound (C) images of the patient's right eye prior to undergoing vitrectomy on November 9, 2015. Small white infiltrates (white arrow in A) were observed at the border between the host and donor corneal graft. Retinal fundus and B-scan ultrasound examinations revealed a vitreous opacity. D and E, slit-lamp examination (D) and retinal fundus (E) images of the patient's right eye post intensive treatment (D: slit-lamp image taken on May 10, 2016; E: retinal fundus image taken on December 11, 2015). As can be seen in the images, the white infiltrates on the cornea and vitreous opacity had completely disappeared.
