From: Repeat corneal graft failure due to graft-to-host herpetic infection
Immunohistochemical analysis of the host cornea. (A) Immunohistochemical analysis of the host cornea for herpes simplex virus 1 (HSV-1) was negative (×20). (B) Immunohistochemical examination of the first corneal graft (after the first repeat keratoplasty) showed a strong signal for HSV-1 (×20). (C) Immunohistochemical analysis of the second corneal graft (after the second repeat keratoplasty) also revealed a strong signal for HSV-1 (×20). Scale bar = 100 μm.
