A 17-year-old boy suffered an injury to his left eye when, during a car crash, a sharp sliver of glass penetrated his eye, damaging his lens and uveal tract. The glass was removed and the injury repaired with complete recovery. However, 3 weeks later he noticed some redness in the left eye and photophobia, followed by pain and severe visual impairment. The left eye was removed and histologic examination showed an extensively infiltrated uveal tract with abundant lymphocytes and mononuclear cells. Two weeks later the other eye began to show the same symptoms. Since the lens was damaged the most likely scenario is that: A. this is an example of immediate hypersensitivity. B. sequestered antigen was released and initiated an immune response. C. some of the glass must have penetrated the right eye as well. D. the bacteria entered the damaged eye and is causing an infection in both eyes.
