Six months after a successful cornea transplant, the patient reports two weeks of red eye and a “white spot” on the cornea.

The most likely cause for this patient’s presentation is:

a. a loose suture at 12 o’clock and it must be removed immediately b. an episode of epithelial rejection and the patient should use Q1 hour topical steroids c. a bacterial or fungal infection - the area should be cultured and empirical antibiotics should be started immediately d.  a herpetic dendrite and the patient should be started on topical antivirals
