Blindness is a major public health problem in most developing countries. Corneal ulcer (Keratitis) is a major cause of blindness throughout the world. About 10% cases of blindness are due to corneal ulcer. “Corneal ulcer means loss of corneal substances as a result of infection and formation of raw, excavated area.” Bacterial keratitis is an acute or chronic, transient or recurrent infection of the cornea with varying predilection for anatomical and topographical parts of the cornea like marginal or central. This study demonstrates the Novel pathogenic bacteria Exiguobacterium aurantiacum with bad pigment production, which are causing corneal ulcer and determine the best possible empirical therapy and specific therapy. Particular attention should be given to this condition as it can progress very rapidly with complete corneal destruction can be occur within 24–48 hours.

Keywords: Corneal Ulcer, Exiguobacterium aurantiacum, Molecular characterization, Antibiotic treatment, Pigment.
