Traumatic endophthalmitis and the outcome after vitrectomy in young children

Pediatric Endophthalmitis Over the Last Five Decades: A Case Report and Systematic Review

INTRODUCTION

Pediatric infectious endophthalmitis is a rare, severe ocular infection that can have devastating consequences. It may be exogenous or endogenous, with exogenous endophthalmitis being more common. Current data on the etiology, microbiology, antibiotic treatments and outcomes in pediatric cases is limited.

PURPOSE

To summarize the etiology, microbiology, visual outcomes and management of pediatric endophthalmitis.

METHODS

A literature review was conducted on cases of pediatric endophthalmitis published from 1980 to 2022, identified through searches of PubMed, Medline, Web of Science and Google Scholar databases.

RESULTS

A total of 796 patients were included. Ocular trauma was the most common cause with 623 patients (78.3%), followed by posteye surgery with 100 patients (12.6%) and endogenous endophthalmitis with 67 patients (70 eyes) (8.4%). Among culture-positive cases, gram-positive microorganisms predominated. Treatment involved pars plana vitrectomy in 608 patients (76%) and intraocular antibiotics in 590 patients (74%). Favorable visual acuity (≥20/200) was achieved in 30.5% of patients, 20% had no light perception and 12.5% developed poor anatomical outcomes with phthisis bulbi.

CONCLUSION

Our review provides insights into the etiology, epidemiology, microbiology, treatment and visual outcomes of pediatric endophthalmitis based on available literature worldwide.

The Role of Silicone Oil in the Surgical Management of Endophthalmitis: A Systematic Review

(1) Background: We aimed to systematically review the current literature to evaluate if in patients with postoperative endophthalmitis treated with pars plana vitrectomy, silicone oil tamponade could provide a useful contribution to the control and eradication of infection and if it could influence anatomical recovery and functional outcome. (2) Randomized controlled trials, cross-sectional studies, case series, and case reports published in the English language in peer-reviewed journals were included. No restriction was placed based on the study location. We used medical subject headings (MeSH) and text words. We searched MEDLINE (OVID and PubMed), Google Scholar, ISI Web of Science (Thom-on-Reuters), and the Cochrane Library (Wiley) from January 1995 to the present. To ensure literature saturation, we scanned the reference lists of included studies or relevant reviews identified through the search. Risk of Bias was assessed using the Newcastle-Ottawa scale for longitudinal studies and Cochrane risk-of-bias tool for randomized trials. (3) Results: abstracts of 75 articles were selected for full-text reading; after full-text reading, 44 articles were taken into consideration in the systematic review. 5 out of 7 in vitro experimental studies demonstrated antimicrobial activity against different species of bacteria and fungi. The use of SO as endotamponade associated with PPV led to better visual acuity and a lower rate of retinal detachment and the need for additional surgery. (4) Conclusions: Silicone oil reduces the risk of postoperative retinal detachment, especially in case of undetected retinal breaks, produces compartmentalization of the eye, may lead to early visual recovery, allows laser photocoagulation, prevents severe postoperative hypotony and has antimicrobic activity due to an inhibitory effect for several species of pathogens. Concerns regarding possible toxic effects on the retina and optic disc, compartmentalization and impaired washout of pathogen toxins have been reported. It may also influence intravitreal antibiotic distribution and clearance.

Outcomes and Prognostic Factors of Posttraumatic Endophthalmitis: A Three-Year Retrospective Study

Purpose

To describe the clinical features, management, and outcomes of patients with posttraumatic endophthalmitis (PTE) and to determine risk factors for poor visual prognosis.

Methods

We retrospectively reviewed the medical records of 42 consecutive patients presenting with PTE who were treated at our institution between 2017 and 2019. Each patient's data, including demographic characteristics, ocular injury details, surgical records, patient outcomes, and laboratory results, were collected and analyzed. Multivariate analysis was conducted to determine the factors associated with poor visual outcomes.

Results

In our series, male (n = 36, 85.7%) and patients below 60 years of age (20–40 years, 23.8%; 40–60 years, 57.14%) comprised most of the total cohort. On presentation, 39 (92.8%) of the 42 PTE patients presented best-corrected visual acuity (BCVA) worse than counting fingers. Pars plana vitrectomy (PPV) was performed in all the patients. 59.5% (n = 25) of the patients' BCVA improved after surgery and 33.3% (n = 14) achieved BCVA of 20/200 or better. The rate of evisceration was 7.1% (n = 3). Of the 42 specimens, the culture was positive in 10 (23.8%) eyes. By univariate analysis, factors including sex, occupation, systemic disease, source of trauma, lens injury, silicone oil tamponade, usage of intravitreal antibiotics, BCVA at presentation, and culture positive for any organism did not affect the final visual outcome. The features associated with poor BCVA (grouped as < 20/200 and ≥ 20/200) included older age (P=0.035), corneal-sclera wound (versus sclera wound) (P=0.047), retained intraocular foreign bodies (IOFBs) (P=0.006), treatment > 3 days (versus < 1 day) (P=0.033), and more times of surgeries (P=0.033).

Conclusions

PTE is a severe complication of penetrating globe injuries associated with irreversible visual loss. Our results highlighted the importance of conducting early therapeutic PPV and IOFB removal to achieve better visual outcomes.
