Autoimmune peripheral ulcerative keratitis associated with collagen vascular diseases and isolated Mooren's ulcer [Figure 1]a are important causes of peripheral corneal melting.[1] Lid margin disease also leads to perilimbal immune ulceration with a lucid interval, where the lid touches the cornea[2] [Figure 1]b.

Rarely, infectious etiologies such as primary herpes simplex keratoconjunctivitis[3] [Figure 1]c or pythium keratitis[4] [Figure 1]d can also cause peripheral corneal infiltrates and guttering.

  Discussion Top

Looking for discharge and color of infiltration as well as microbiology in suspicious cases is important as steroids used for treating immune corneal melts can flare up herpes simplex epithelial disease or pythium keratitis.
