Corneal sequestration appears as a variable shaped, size, and depth, brown to black lesion that may be so dense that slit lamp biomicroscopy cannot accurately estimate the depth of stromal involvement. Melvin was pretty cute. Some cats, instead of developing the cytolytic form of the herpetic ocular disease, which is the result of active viral replication and cell lysis, will develop an immunopathologic form that manifests with stromal keratitis.
