Abstract:
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.
Insights
Moraxella corneal ulcers can cause severe vision loss and even eye loss, despite antibiotic treatment. These uncommon ulcers often occur in patients with underlying health issues, highlighting the need for awareness.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Moraxella corneal ulcers are rare but can lead to severe ocular complications.
- Prompt diagnosis and treatment are crucial for managing these infections.
Observation:
- A series of eight cases of Moraxella corneal ulcers were reviewed over six years.
- Four cases developed descemetoceles and/or perforations despite appropriate antibiotic therapy.
- Two patients experienced complete loss of the eye.
Findings:
- Most patients (75%) had poor final visual acuity (count fingers or less).
- Ulcers were associated with systemic diseases like alcoholism and malnutrition.
- Pre-existing ocular surface diseases were also common comorbidities.
Implications:
- Moraxella corneal ulcers pose a significant risk of vision and eye loss.
- Awareness of these risks is essential for clinicians managing corneal infections.
- Further research into risk factors and treatment strategies may be warranted.
