Declining incidence of neonatal endophthalmitis in the United States

Microbiological Landscape and Epidemiology of Endophthalmitis in Children and Adolescents in a Multi-Tier Ophthalmology Network in India: An Electronic Medical Record-Driven Analytics Report

PURPOSE

To study the epidemiology and microbiological landscape in patients (≤21 yrs) diagnosed with endophthalmitis across a multi-tier ophthalmology network in India.

METHODS

This cross-sectional hospital-based study included 1,041 patients (≤21 yrs) diagnosed with endophthalmitis, between April 2012 and May 2022. The data were collected using an electronic medical record system.

RESULTS

Bacteria (24%) was the most common etiology followed by fungus (2%). The majority of the patients were male (66%) with a mean age of 8.37 ± 5.99 years. The most common age group was middle childhood (6-11 years) with 365 (35.06%) patients. The patients were more commonly from the lower socio-economic status (60.81%) and urban geography (49%). The common cause of endophthalmitis was trauma (59.33%) and amongst the 279 culture positive eyes, the predominant bacteria isolated was Streptococcus pneumoniae followed by Bacillus species and fungus included predominantly Aspergillus and Candida species. The most common surgical intervention performed was intraocular antibiotics (74%) followed by pars plana vitrectomy (52%).

CONCLUSION

The most common etiology of endophthalmitis in children is bacterial and traumatic in nature and presented from the lower socio-economic status. A half of the eyes warranted a vitreo-retinal surgical intervention.     .

Neonatal Endogenous Endophthalmitis: A Case Report

The aim of this study is to share our experience of a baby boy patient who presented with rare endogenous endophthalmitis that ended up with exudative retinal detachment; emphasizing the clinical presentation, follow-ups progression, and the management plan.

A case report of a one-month-old preterm baby boy presented with eye discharge in his left eye (OS) associated with eyelid swelling and chemosis for four days. His clinical examination revealed a congested left eye with proptosis, absent red reflex, and normal intraocular pressure (IOP) while a portable slit-lamp examination showed an edematous left eye with cloudy cornea but no infiltrates and no view to the posterior segment. Blood, cerebrospinal fluid (CSF), and ocular discharge were cultured, and all came negative and the patient started on empirical antibiotics. B-scan shows dense infiltrates in the vitreous cavity with subretinal fluid. Diagnostic intravitreal paracentesis was done which showed the growth of Pseudomonas aeruginosa and a diagnosis of endogenous endophthalmitis is made then a directed management plan was initiated. Unfortunately, a few days later a repeated B-scan was ordered to the left eye and it shows exudative retinal detachment, and a referral to retinal surgery service was consulted. After further follow-ups, B-scan showed resolving retinal detachment with a short shrunken eye, marked ocular wall thickening, and a relatively short axial length which is consistent with prephthisical changes hence, an oculoplasty referral was done for ocular prosthesis later on.

Endogenous endophthalmitis is a rarely encountered intraocular infection yet it carries devastating consequences that may threaten vision. Therefore, a high index of suspicion is essential for early detection of the disease to prevent serious complications and achieve good visual outcomes.

Primary evisceration for neonatal endogenous endophthalmitis: A report of two cases

Purpose

To present two cases of neonatal endophthalmitis with poor prognosis that were managed with primary evisceration.

Observations

Case 1 is a 27-weeks’ gestation neonate who developed Pseudomonas aeruginosa endophthalmitis complicated by globe rupture. Case 2 describes a 34-weeks’ gestation neonate with Serratia marcescens endophthalmitis. Both patients had poor prognosis and thus underwent primary evisceration with good long-term cosmetic outcomes at 15 years and 17 months, respectively.

Conclusions and Importance

Primary evisceration should be considered in neonates with endophthalmitis with a poor prognosis and can result in good long-term cosmesis.

Trends in Infantile Endogenous Endophthalmitis Hospitalizations in the United States: An Analysis from 2007 through 2014 Using the National Inpatient Sample

PURPOSE

To determine the annual change in incidence of neonatal and infantile endogenous endophthalmitis in the United States between 2007 and 2014 and identify associated risk factors for development of endophthalmitis and mortality.

DESIGN

Retrospective cross-sectional study.

PARTICIPANTS

Neonates (<28 days; n = 1650) hospitalized for endogenous endophthalmitis between 2003 and 2014 and infants (age range, 28 days-1 year; n = 1850) hospitalized between 2007 and 2014 across United States community hospitals were analyzed.

METHODS

The Nationwide Inpatient Sample database was queried to identify neonates hospitalized for endogenous endophthalmitis between 2003 and 2014 and infants hospitalized between 2007 and 2014 across the United States. National and regional incidence of neonatal and infantile endogenous endophthalmitis and comorbidities as well as risk factors in the development of the disease and predictive factors for mortality from the years 2007 through 2014 were calculated.

MAIN OUTCOMES AND MEASURES

National incidence, regional incidence, and risk factors for development of neonatal and infantile endogenous endophthalmitis.

RESULTS

The rate of decline in incidence of neonatal endogenous endophthalmitis was 4% from 2003 through 2014. The rate of decline in the infantile population was 7% from 2007 through 2014. In 2007, an estimated 291 total cases of infantile endophthalmitis were identified, in comparison with 140 cases in 2014. Comorbidities prevalent in the endophthalmitis population included prematurity, respiratory disorders, perinatal infections, and retinopathy of prematurity (ROP). Significant positive predictors for the development of endogenous endophthalmitis based on multivariate logistic regression were perinatal infections, candidemia, bacteremia, very low birth weight, prematurity, respiratory disorders, and ROP. Descriptive analyses showed that the in-hospital mortality rate for patients identified with endophthalmitis was 1.55% in comparison with infants without endophthalmitis.

CONCLUSIONS

The incidence of endogenous endophthalmitis declined in both the neonatal and infantile population from 2007 through 2014. Odds of endogenous endophthalmitis were higher for premature and low-birthweight infants and those identified with perinatal infections, candidemia, bacteremia, respiratory disorders, or ROP. These findings are consistent with the decline observed in pediatric infectious disease-related hospitalizations in general.

Endophthalmitis

Endophthalmitis is a rare but severe form of ocular inflammation due to infection of the intraocular cavity that can lead to irreversible visual loss if not treated properly and timely. It can be classified as exogenous or endogenous based on the transmission route of the infectious source. Exogenous endophthalmitis occurs when infecting organisms gain entry into the eye via direct inoculation, while endogenous endophthalmitis occurs when infectious agents hematogenously spread into the eye from a distant focus of infection. The diagnosis of endophthalmitis depends mostly on the clinical findings on ophthalmological examination. Delayed diagnosis of endogenous endophthalmitis can lead to not only visual loss, but also increased risk of mortality. Since ocular and systemic symptoms of endophthalmitis are usually non-specific, early diagnosis relies on the alertness of clinicians. Early diagnosis and proper treatment are keys to saving the eye. Following advances in vitreoretinal pharmacotherapy and surgical technology, early surgical intervention is the current trend in the management of endophthalmitis.

Clinical profile and outcomes of pediatric endogenous endophthalmitis: A report of 11 cases from South India

AIM

To study the clinical profile and outcomes of pediatric endogenous endophthalmitis from a tertiary eye hospital in South India.

METHODS

A total of 13 eyes of 11 children presented to us with varied symptoms and presentations of endogenous endophthalmitis, over a five-year period from January 2010 to December 2015 were studied. Except for two eyes of a patient, vitreous aspirates were cultured from all 11 eyes to isolate the causative organism. These eleven eyes also received intravitreal injections. All patients were treated with systemic antibiotics.

RESULTS

Two cases had bilateral endophthalmitis. Ages ranged from 4 d to 11 years. Five cases were undiagnosed and treated, before being referred to our center. Ten of the 13 eyes underwent a core vitrectomy. The vitrectomy was done at an average on the second day after presenting (range 0-20 d). Five of the 11 vitreous aspirates showed isolates. The incriminating organisms were bacteria in three and fungus in two. An underlying predisposing factor was found in seven patients. At a mean follow-up 21.5 mo, outcome was good in 7 eyes of 6 cases (54%), five eyes of four cases (38%) ended up with phthisis bulbi while one child died of systemic complications.

CONCLUSION

Endogenous endophthalmitis is a challenge for ophthalmologists. Early diagnosis and intervention is the key for a better outcome.

MR imaging findings of endophthalmitis

Endophthalmitis is a sight-threatening ophthalmologic emergency. The clinical diagnosis is often challenging, and delayed diagnosis may exacerbate the poor visual prognosis. B-scan ultrasonography or spectral domain optical coherence tomography are imaging aids at the clinician's office. Cross-sectional imaging such as CT and particularly MRI can also help in the assessment of disease extent or complications. MR imaging findings are rarely described in the literature. Here, we discuss the spectrum of imaging findings of endophthalmitis and correlate them with key anatomic and pathophysiologic details of the globe. Early disease is often subtle on MR imaging with thick uveal enhancement, while advanced disease demonstrates retinal/choroidal detachment, vitreal exudates and peribulbar inflammation. Other noninfectious inflammatory diseases of the globe can show similar findings; however, MR diffusion-weighted images help identify infectious exudates and evaluate response to therapy. Knowledge of the spectrum of imaging findings of this disease is important for radiologists and help in the management decision process.

Endogenous endophthalmitis: diagnosis, management, and prognosis

Endogenous endophthalmitis is an ophthalmic emergency that can have severe sight-threatening complications. It is often a diagnostic challenge because it can manifest at any age and is associated with a number of underlying predisposing factors. Microorganisms associated with this condition vary along a broad spectrum. Depending upon the severity of the disease, both medical and surgical interventions may be employed. Due to rarity of the disease, there are no guidelines in literature for optimal management of these patients. In this review, treatment guidelines based on clinical data and microorganism profile have been proposed.

Bilateral endogenous endophthalmitis caused by vancomycin-resistant Staphylococcus epidermidis in a neonate

BACKGROUND

Neonatal bilateral endogenous endophthalmitis is rare and often results in devastating visual outcome.

FINDINGS

An 18-day-old neonate presented with whitening of the cornea in the left eye. The child was examined under anesthesia, and a diagnosis of bilateral endogenous endophthalmitis was made. Vitreous biopsy from the left eye showed no growth. Blood samples showed growth of Staphylococcus epidermidis which was multidrug resistant (including vancomycin) but sensitive to piperacillin-tazobactam. The patient was managed with bilateral intravitreal injections of piperacillin-tazobactam and systemic cefpodoxime. Systemic and topical antibiotics were given for 3 and 8 weeks, respectively, and infection was controlled. At 2-year follow-up, the right eye is fixing and following to light with clear view of the fundus and the left eye has a clear cornea with red glow of the fundus.

CONCLUSIONS

Vancomycin-resistant S. epidermidis may be a cause of endogenous endophthalmitis. Intravitreal piperacillin-tazobactam and systemic cefpodoxime were used to eliminate the infection in this neonate.

Pediatric infectious endophthalmitis: a review

Infectious endophthalmitis is a rare but severe complication of septecemia, intraocular surgeries, or penetrating eye trauma. The etiology, prognosis, and management of pediatric endophthalmitis resulting from exogenous and endogenous infections are reviewed. Open-globe trauma and glaucoma surgery are the most frequent causes of endophthalmitis in children, whereas endogenous infection is the least common cause. Streptococcus and Staphylococcus species are common bacterial agents in both posttraumatic and postoperative pediatric endophthalmitis, whereas Candida albicans is a commonly reported organism in endogenous endophthalmitis. Additionally, Streptococcus pneumoniae and Haemophilus influenzae appear more likely as pathogens in children than in adults. The clinical manifestations and outcome usually correlate with the virulence of the infecting organism. The visual prognosis of endophthalmitis is generally poor.

Treatment outcomes and clinicomicrobiological characteristics of a protocol-based approach for neonatal endogenous endophthalmitis

PURPOSE

To describe the outcomes and clinicomicrobiological profile of 11 years of a protocol-based management in neonatal endogenous endophthalmitis.

METHODS

This was a retrospective interventional study of endogenous endophthalmitis in 31 eyes of 26 neonates. The protocol for active infection included systemic antimicrobials, vitreous and/or aqueous tap, and intravitreal antimicrobials under topical or general anesthesia along with core vitrectomy in selected cases. Blood, urine, umbilicus, aqueous, and vitreous samples underwent microbiological evaluation. Retinopathy of prematurity screening and treatment were done when indicated. Primary outcome was anatomic status assessed by comprehensive eye examination and by fundus photography whenever possible.

RESULTS

Twenty-one of 26 babies (81%) were preterm. Two types of presentations included those with a fulminant appearance (24 eyes) and those with focal retinitis detected during routine screening (7 eyes). Vitreous culture was positive in 12/20 eyes (60%). Pseudomonas aeruginosa (8) was the most common isolate. Incorrect initial diagnosis was common. Treatment included intravitreal injections in 26 eyes, 10 of which also underwent vitrectomy. Twenty-four of the 26 patients (92%) received parenteral antimicrobials and 17 had evidence of systemic infection. All eyes with a fulminant presentation developed phthisis, while all focal fungal cases were salvaged.

CONCLUSIONS

Neonatal endogenous endophthalmitis has 2 distinct presentations. Focal retinal infections have good visual and anatomical outcomes while fulminant nosocomial cases do poorly. Management under topical anesthesia can be an alternative strategy for sick babies that cannot undergo surgery under general anesthesia due to systemic morbidity. Awareness about early diagnostic signs may help early referral.

Candida species lens abscesses in infants with a history of neonatal Candida sepsis

We report 3 patients who were delivered prematurely and who developed a lens opacity with signs of ocular inflammation at a postgestational age of 10-52 weeks. All patients had been treated for Candida sepsis as neonates. Each patient underwent lensectomy and anterior vitrectomy. In 2 infants Candida albicans was cultured from the lens/anterior chamber membrane; in 1 Candida parapsilosis was cultured from a lens aspirate. Despite eradication of the fungal infection, outcomes were poor: 2 eyes developed glaucoma, and 1 developed a retinal detachment with subsequent phthisis.

Intraocular infections in the neonatal intensive care unit

Background

The purpose of this study was to report on the incidence and treatment outcomes of endogenous endophthalmitis among newborns in the neonatal intensive care unit (NICU) of a single medical center.

Methods

This was a noncomparative, retrospective case series of endogenous endophthalmitis among infants at the Jackson Memorial Hospital NICU treated between March 1, 2002 and March 1, 2007.

Results

Of 4323 infants admitted to the NICU, seven eyes of six (0.139%) infants (two males, four females) were diagnosed with endophthalmitis during the study period. Four patients were born prematurely with a mean gestational age of 27.5 weeks and a mean birth weight of 1153 g. Retinopathy of prematurity was reported in two of the six patients. Mean follow-up was 3.5 years. The diagnosis was confirmed by positive cultures or polymerase chain reaction testing at a median age of 34 postnatal days. Positive cultures included Candida albicans (n = 4), Pseudomonas aeruginosa (n = 1), and Herpes simplex type 2 (n = 1). All patients received systemic treatment and five received adjunctive ophthalmic interventions, including intravitreal antibiotics in five eyes of four patients and vitrectomy with pars plana lensectomy in three eyes. One patient underwent primary enucleation and another had delayed evisceration. In the remaining five eyes, there was a normal appearing posterior segment and normal intraocular pressures at last follow-up.

Conclusion

Endogenous endophthalmitis is a rare complication in infants in the NICU, but may occur in patients with candidemia, bacteremia, retinopathy of prematurity, and low birth weight. Despite early and appropriate treatment, involved eyes may have poor outcomes.
