Not all HSV-1–infected corneas develop severe HSK lesions. (a, b) The corneal opacity and angiogenesis was determined at different time points post ocular HSV-1 infection using a hand-held slit lamp microscope. (c) Frequency of corneas with severe and mild HSK lesions on Day 15 postinfection. (d) Representative image of the eye with no disease, mild, and severe HSK lesions. Images were taken 15 days post infection. Data shown is the mean of two independent experiments with similar results. In each experiment 12 eyes were infected with HSV-1.
