Corneal perforation due to Helminthosporium and Mima polymorpha.

This apparently is the first reported case of corneal perforation due to a mixed infection of Helminthosporium species and Mima polymorpha. These 2 organisms separately rarely cause ocular infection and when present together could produce serious damage to the eye. In long-standing diseases of the cornea, mixed infection should be suspected when the infection fails to respond to conventional medical therapy. Thorough laboratory evaluation should be done. Selection of appropriate antibiotics should be based on clinical impression, initial Gram stain findings and final cultural results.
