Moraxella keratitis.

Moraxella corneal ulcers are uncommon but may be complicated by marked inflammation and corneal perforation. In a series of eight cases treated over a period of 6 years, despite appropriate antibiotic therapy, descemetoceles and/or perforations developed in four cases, resulting in loss of the eye in two cases. In our series, the final visual acuity was count fingers or less in most patients (six of eight; 75%). Ulcers not only occurred in patients with systemic diseases, including alcoholism and malnutrition, but also in patients with various pre-existing ocular surface diseases. It is important to be aware of the potential of Moraxella ulcers to result in loss of vision and the eye.
