Introduction:
The purpose of this study was to report the first case of acute bacterial keratitis produced by methicillin-resistant Staphylococcus aureus after the implantation of two intracorneal ring segments during an uneventful procedure for treating keratoconus in a 13-year-old child.
Case Report:
A patient with grade III keratoconus underwent an implantation of intracorneal ring segments with no complications during the procedure. Three days later, a whitish corneal infiltrate appeared in between the union of both corneal rings. Sample cultures were positive for methicillin-resistant S. aureus (MRSA). Corneal infiltrate did not improve despite intensive topical and systemic antibiotics. Melting appeared even after the explantation of both corneal rings. Keratoplasty à chaud had to be performed to preserve the eye integrity.
Conclusions:
MRSA keratitis following intracorneal ring segment implantation is a rare but severe complication that can lead to a therapeutic penetrating keratoplasty to definitely cure the process.
Insights
A severe methicillin-resistant Staphylococcus aureus (MRSA) infection developed in a child after keratoconus surgery. This rare complication required a corneal transplant to save the eye.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Keratoconus is a progressive eye condition requiring surgical intervention.
- Intracorneal ring segments are used to correct keratoconus.
- Bacterial keratitis is a serious infection of the cornea.
Purpose of the Study:
- To report the first case of acute bacterial keratitis caused by methicillin-resistant Staphylococcus aureus (MRSA).
- To describe this complication following intracorneal ring segment implantation for keratoconus.
- To highlight the management and outcome in a pediatric patient.
Main Methods:
- A 13-year-old child with grade III keratoconus underwent uneventful intracorneal ring segment implantation.
- Postoperative monitoring revealed a corneal infiltrate at the ring union site.
- Microbiological cultures identified methicillin-resistant S. aureus (MRSA).
Main Results:
- The patient developed acute bacterial keratitis due to MRSA three days post-surgery.
- The infection was resistant to intensive topical and systemic antibiotic treatment.
- Corneal melting occurred despite explantation of the ring segments.
Conclusions:
- MRSA keratitis is a rare but severe complication after intracorneal ring segment implantation.
- Aggressive infections may necessitate therapeutic penetrating keratoplasty.
- Prompt diagnosis and management are crucial for preserving ocular integrity.
