Slit-lamp photography of the left eye at 6 months after presentation shows a relapse with rapid clinical deterioration. Central corneal edema overlying an area of medium-sized, non-pigmented KPs, with some degree of superficial, gray-white, dry stromal infiltrates was present (a). One week later, multifocal paracentral stromal infiltrates without epithelial defect developed, along with recurrent radial keratoneuritis and worsening of the anterior chamber inflammation (b). Despite aggressive treatment, the corneal lesions became enlarged and rapidly progressed with dense stromal infiltrates and 2 mm hypopyon (c-d), requiring therapeutic penetrating keratoplasty
