Abstract:
Endophthalmitis results from hematogenous seeding of the eye in preterm infants with candidiasis. Early systemic therapy decreases the frequency of eye involvement, now only about 6% in infants with systemic candidiasis. Eye disease can occur on the first day, but is more likely with prolonged candidemia. Candida albicans and C tropicalis predominate in newborns. Indirect ophthalmoscopy will identify the characteristic unilateral or bilateral, yellow-white, fluffy, retinal or vitreal balls with frequent hemorrhage or inflammatory vitreous haze. Systemic antifungal therapy alone usually results in good visual outcome, but unresponsive or recurrent lesions are reported. Lens abscesses presenting as cataracts may be seeded before regression of the tunica vasculosa lentis, leaving an infection nidus in a subsequently avascular structure that is poorly reached by antifungal drugs. Lensectomy may be required to clear the visual field and the infection. Candidemia is also implicated in progression of retinopathy of prematurity to stage 3 or beyond, possibly due to induction of cytokines or angiogenic factors.
Insights
Ocular candidiasis in preterm infants can lead to endophthalmitis, a serious eye infection. Early antifungal treatment is crucial for preventing vision loss in infants with candidemia.
Area of Science:
- Ophthalmology
- Neonatology
- Infectious Diseases
Background:
- Endophthalmitis in preterm infants is a severe complication of systemic candidiasis.
- While early systemic antifungal therapy reduces ocular involvement, it still occurs in approximately 6% of cases.
- Prolonged candidemia increases the risk of eye disease, which can manifest early or later in infancy.
Purpose of the Study:
- To review the presentation, diagnosis, and management of endophthalmitis in preterm infants with candidiasis.
- To highlight the role of Candida species in neonatal eye infections.
- To discuss the impact of candidemia on retinopathy of prematurity.
Main Methods:
- Review of clinical presentations and diagnostic findings.
- Ophthalmoscopic examination for characteristic retinal and vitreal lesions.
- Assessment of treatment outcomes with systemic antifungal therapy and surgical interventions.
Main Results:
- Characteristic findings include unilateral or bilateral yellow-white retinal/vitreal lesions with hemorrhage and vitreous haze.
- Systemic antifungal therapy is often effective, but some cases require lensectomy for persistent or recurrent infections, especially lens abscesses.
- Candidemia is associated with the progression of retinopathy of prematurity.
Conclusions:
- Prompt diagnosis and systemic antifungal treatment are vital for preserving vision in preterm infants with ocular candidiasis.
- Ocular complications, such as lens abscesses, may necessitate surgical intervention.
- The link between candidemia and retinopathy of prematurity progression warrants further investigation.
