Insights
Endogenous endophthalmitis in preterm infants is a severe condition. Prompt diagnosis and tailored antibiotic treatment, including intravitreous injections, are crucial for better visual and vital outcomes.
Area of Science:
- Ophthalmology
- Neonatal Medicine
- Infectious Diseases
Background:
- Endogenous endophthalmitis is a rare but serious eye infection.
- It disproportionately affects vulnerable populations, including preterm infants.
Observation:
- A preterm infant developed Pseudomonas aeruginosa endogenous endophthalmitis secondary to catheter-associated bacteremia.
- The infant received initial intravenous antibiotics, followed by intravitreous Ceftazidime and subconjunctival betamethasone.
Findings:
- Despite treatment, the infant developed vitreoretinal retraction, phacophagia, necessitating a vitrectomy.
- This case highlights the severe visual and vital prognosis associated with this condition.
Implications:
- Emphasizes the critical need for rapid biological diagnosis to guide appropriate antibiotic therapy.
- Suggests the potential value of antibiotic intravitreous injections in managing endophthalmitis in preterm neonates.
Abstract:
Endogenous endophthalmitis is a rare eye disease, affecting vulnerable subjects (such as preterm or older elderly subjects), with reserved visual and sometimes vital prognosis. We present a preterm boy, born at 35 weeks and 2 days gestation, who developed a right eye Pseudomonas aeruginosa endogenous endophthalmitis secondary to a left-foot peripherical catheter-infection-associated bacteremia. He had a first intravenous antibiotic therapy associating third-generation cephalosporin and fluoroquinolone, then Ceftazidime® by intravitreous injection and a subconjunctival injection of betamethasone. Because of the development of vitreoretinal retraction, phacophagia and vitrectomy were performed. We point and discuss the severity of this disease, associated with poor visual and vital prognosis, and the importance of prompt biological diagnosis so that the appropriate intravenous antibiotic therapy is chosen. Treatment is also discussed, especially the interest value of antibiotic intravitreous injection in preterm infants.
