Abstract
Endogenous endophthalmitis represents an ophthalmological emergency requiring immediate diagnostics and treatment. Pathogens should be detected using appropriate methods, such as the Freiburg endophthalmitis set. In bacterial endophthalmitis both Gram-positive and Gram-negative bacteria can be detected. Frequent underlying sources include endocarditis, gastrointestinal or urogenital surgery, indwelling venous catheters, liver abscesses, skin or soft tissue infections, meningitis or less commonly, intravenous drug abuse. The treatment consists of systemic and intraocular administration of antibiotics and vitrectomy. Systemic or intraocular corticosteroids can additionally be considered.

Abstract
PURPOSE The index review aims to provide an update on the role of corticosteroids and steroid-sparing immunomodulatory therapy (IMT) in managing patients with infectious uveitis. METHOD Narrative literature review. RESULTS Corticosteroids and immunomodulatory therapy (IMT) focus on the host defense system instead of the pathogen, adjusting exaggerated inflammatory reactions to reduce potential harm to ocular tissues. Systemic or local corticosteroids are primarily selected as adjunctive medication for infectious uveitis. Concomitant corticosteroids have also been used in cases of paradoxical worsening in ocular tuberculosis and immune recovery uveitis in cytomegalovirus (CMV) retinitis. While there is no well-established evidence to support the use of IMT in infectious uveitis, it is occasionally used in clinical settings to treat persistent inflammation following resolution of infection such as cases of ocular tuberculosis and ocular syphilis where an insufficient response is observed with corticosteroids. CONCLUSION There is no consensus on the position of immunomodulatory therapy in the management of infectious uveitis with different etiologies. The index review provides an overview of available adjunctive corticosteroids and IMT options to assist clinicians in managing such disease entities more efficiently.

Intravitreal injections as a leading cause of acute postoperative endophthalmitis-a regional survey in England. Eye (Lond) 2023; 37:163-169. [PMID: 34949787 PMCID: PMC9829718 DOI: 10.1038/s41433-021-01886-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 11/18/2021] [Accepted: 11/29/2021] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND To evaluate the characteristics, treatment patterns and outcomes of acute postoperative endophthalmitis. METHODS Patients presenting with acute postoperative endophthalmitis between January 2017 to December 2019 were identified from hospital records in this multicentre retrospective cohort study. Clinical records were reviewed for visual acuity (VA) at various timepoints, cause of endophthalmitis, microbiological results, treatments and complications. RESULTS Forty-six eyes of 46 patients were included. Intravitreal injections were the leading cause of acute postoperative endophthalmitis (n = 29; 63%), followed by cataract surgery (n = 8; 17%), vitreoretinal surgery (n = 7; 15%), and secondary intraocular lens insertion (n = 2, 4%). The absolute risk of endophthalmitis was 0.024% (1:4132) for intravitreal injections, 0.016% (1:6096) for cataract surgery, and 0.072% (1:1385) for vitreoretinal surgery. The majority of patients (n = 38; 83%) had better VA at 6 months compared to presentation, although fewer (n = 13; 28%) maintained similar or better VA compared to before the precipitating surgery. Twenty-four cases yielded positive culture results, of which staphylococcus epidermidis was the most commonly isolated organism. Microbiological yield was not associated with better final visual outcomes. Patients who underwent therapeutic vitrectomy (n = 15; 33%) had poorer VA at presentation, but subsequently achieved visual outcomes comparable to those who received medical treatment alone. There was no difference in time to presentation, visual outcome and retinal detachment rates among the different causative procedures. CONCLUSION Intravitreal injections were the most common cause of endophthalmitis in our region, primarily because of their higher frequency compared to other intraocular procedures. In this cohort, the primary procedure had no effect on presentation, management or visual outcomes.

Abstract
Although infectious endophthalmitis after intravitreal antivascular endothelial growth factor injections is rare, it is the most feared and potentially devastating complication of this procedure. There is no high-level evidence to provide definitive guidance on the management of endophthalmitis occurring after intravitreal injection (IVI). This clinical practice update reviews the published literature regarding post-IVI endophthalmitis and highlights areas in which further research is needed to better guide its management.

Abstract
Staphylococcus lugdunensis is a rare causative organism of endophthalmitis following intravitreal injections. It presents an aggressive disease course with potentially devastating outcomes. In this case, the patient presented late with a severely painful, red eye with a reduced visual acuity from 6/18 to light perception following bilateral intravitreal injections of anti-vascular endothelial growth factor. Strict adherence to the bilateral intravitreal injection protocol meant prevention of infection in the right eye. Intravitreal vancomycin was administered without delay and an emergency vitreous biopsy was performed, confirming S. lugdunensis as the causative organism. An intense course of oral and topical steroids was chosen due to the aggressiveness of this organism. Early vitreo-retinal opinion was sought but the patient was deemed not suitable for vitrectomy due to initial improvements in visual acuity to hand movements. The patient showed improvements in the visual acuity to 1/60, and remains on a weaning regime of oral and topical steroids with no further complications.

Abstract
BACKGROUND Intravitreal medication injections represent the gold standard treatment for a variety of potentially blinding chorioretinal vascular diseases. Despite their excellent safety profile, they are associated with the feared complication of injection-related endophthalmitis (IRE). Though the overall incidence of IRE is low, due to the ever-increasing number of injections being performed, it is a complication that all retina specialists are likely to encounter. This article reviews various factors that could potentially influence the risk of IRE and discusses evidence-based strategies for management. METHOD PubMed was searched for keywords "intravitreal injection" and "endophthalmitis" from the period of 1995-2021. Relevant articles were reviewed and selected articles were analyzed with respect to the incidence, potential preventive factors, clinical presentation, microbial profile, management, and outcomes for IRE. RESULTS There is strong consensus supporting the use of povidone iodine topical antiseptic, eyelid retraction away from the injection site, and avoiding treatment of eyes with active surface or eyelid disease, but there is less agreement on the use of face masks versus "no-talking" policies and optimal anesthetic technique. Current evidence comparing tap and inject or early vitrectomy for treatment of IRE is inadequate to determine an optimal treatment strategy. CONCLUSION Intravitreal injections are sight saving, but even using established prophylactic measures there remains a small but real risk of infectious injection-related complications. Further investigations comparing tap and inject versus vitrectomy may help to establish optimal treatment, although the rarity of IRE makes designing adequately powered prospective trials a difficult task.

Abstract
BACKGROUND Endophthalmitis refers to severe infection within the eye that involves the aqueous humor or vitreous humor, or both, and that threatens vision. Most cases of endophthalmitis are exogenous (i.e. due to inoculation of organisms from an outside source), and most exogenous endophthalmitis is acute and occurs after an intraocular procedure. The mainstay of treatment is emergent administration of broad-spectrum intravitreous antibiotics. Due to their anti-inflammatory effects, steroids in conjunction with antibiotics have been proposed as being beneficial in endophthalmitis management. OBJECTIVES To assess the effects of antibiotics combined with steroids versus antibiotics alone for the treatment of acute endophthalmitis following intraocular surgery or intravitreous injection. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2021, Issue 8), MEDLINE Ovid (1946 to August 2021), Embase Ovid (1980 to August 2021), LILACS (Latin American and Caribbean Health Sciences Literature database) (1982 to August 2021), the ISRCTN registry; searched August 2021, ClinicalTrials.gov; searched August 2021, and the WHO International Clinical Trials Registry Platform; searched August 2021. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA We included randomized controlled trials (RCTs) comparing the effectiveness of adjunctive steroids with antibiotics alone in the management of acute, clinically diagnosed endophthalmitis following intraocular surgery or intravitreous injection. We excluded trials with participants with endogenous endophthalmitis unless outcomes were reported by source of infection. We imposed no restrictions on the method or order of administration, dose, frequency, or duration of antibiotics and steroids. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology, and graded the certainty of the body of evidence for six outcomes using the GRADE classification. MAIN RESULTS We included four RCTs with a total of 264 eyes of 264 participants in this review update. The studies were conducted in South Africa, India, and the Netherlands. All studies used intravitreous dexamethasone for adjunctive steroid therapy and a combination of two intravitreous antibiotics that provided gram-positive and gram-negative coverage for the antibiotic therapy. We judged two trials to be at overall low risk of bias, and the other two studies to be at overall unclear risk of bias due to lack of reporting of study methods. Only one study was registered in a clinical trial register. While none of the included studies reported the primary outcome of complete resolution of endophthalmitis as defined in our protocol, one study reported combined anatomical and functional success (i.e. proportion of participants with intraocular pressure of at least 5 mmHg and visual acuity of at least 6/120). Very low certainty evidence suggested no difference in combined success when comparing adjunctive steroid to antibiotics alone (risk ratio (RR) 1.08, 95% confidence interval (CI) 0.80 to 1.45; 32 participants). Low certainty evidence from two studies suggested that adjunctive dexamethasone may result in having a good visual outcome (Snellen visual acuity 6/6 to 6/18) at 3 months compared with antibiotics alone (RR 1.95, 95% CI 1.05 to 3.60; 60 participants); however, the evidence was less conclusive at 12 months (RR 1.12, 95% CI 0.92 to 1.37; 2 studies; 195 participants; low certainty evidence). Investigators of one study reported improvement in visual acuity, but we could not estimate the effect of adjunctive steroid therapy because the study investigators did not provide any estimates of precision. Only one study examined intraocular pressure (IOP). The evidence suggests that adjunctive dexamethasone may reduce IOP slightly after 12 months of interventions (mean difference -1.90, 95% CI -3.78 to 0.07; 1 study; 167 participants; low certainty evidence). Three studies reported adverse events (retinal detachment, hypotony, proliferative vitreoretinopathy, seclusion of pupil, floaters, and pucker). The total numbers of adverse events were 14 out of 111 (12.6%) for those who received dexamethasone versus 12 out of 116 (10.3%) for those who did not. We could only perform a pooled analysis for the occurrence of retinal detachment: any difference between the two treatment groups was uncertain (RR 1.41, 95% CI 0.53 to 3.74; 227 participants; low certainty evidence). No study reported cost-related outcomes. AUTHORS' CONCLUSIONS The currently available evidence on the effectiveness of adjunctive steroid therapy versus antibiotics alone in the management of acute endophthalmitis after intraocular surgery is inadequate. We found no studies that had enrolled cases of acute endophthalmitis following intravitreous injection. A combined analysis of two studies suggests that use of adjunctive steroids may provide a higher chance of having a good visual outcome at three months than not using adjunctive steroids. However, considering that most of the confidence intervals crossed the null, and that this review was limited in scope and applicability to clinical practice, it is not possible to conclude whether the use of adjunctive steroids is effective at this time. Any future trials should examine whether adjunctive steroids may be useful in certain clinical settings such as type of causative organism or etiology. These studies should include outcomes that take patients' symptoms and clinical examination into account; report outcomes in a uniform and consistent manner; and follow up at short- and long-term intervals.

Abstract
To demonstrate the demographics, associated factors, clinical presentations, microbiology, management, visual outcome and complications of keratitis/scleritis-related endophthalmitis (KSE). A retrospective chart of all endophthalmitis patients diagnosed between September 2001 and August 2011 was reviewed. Only endophthalmitis cases with previous corneal or scleral infection were included in the study. The patients were followed until losing vision or eyeball, becoming phthisis, or the end of 2018. Eighty-seven patients with KSE were identified, all unilateral. The mean age was 56.4 ± 21.4 years. There was a slight male predilection (55 patients, 63.2%). The mean follow-up time was 50 ± 149 weeks. The causative pathogens were identified in 35 patients (40.2%), with the highest frequency being bacteria. The most common bacterium was Pseudomonas aeruginosa (n = 13), and the most common fungus was Aspergillus sp. (n = 5). Fifteen patients achieved (17.2%) final visual acuity (VA) of hand motion or better after treatment. Eyeball removal was performed in 61 (70.1%) patients. From multivariate analysis, the only prognostic factor for poor final VA (worse than hand motion, HM) was poor VA (worse than HM) at the initial visit (relative risk 1.97, 95% confidence interval 1.15–3.36, p = 0.013). KSE is uncommon but has a devastating outcome. We found that the patient’s initial VA was the only predictor for their final vision. P. aeruginosa was the most common identifiable organism in this study. However, several fungal infections were recognised. These findings should raise awareness for treatment of KSE in the tropics.

Abstract
BACKGROUND Postoperative endophthalmitis is among the most feared complications encountered after intraocular surgery. A prompt diagnosis and initiation of treatment are crucial for the visual prognosis, which also depends on the causative microorganism. Despite advances in prevention and the availability of more epidemiological data, most of the evidence for treatment dates back to a single study, the early vitrectomy study (EVS) carried out in the early 1990s. The EVS showed that vitrectomy with intravitreal antibiotics was superior to intravitreal antibiotics alone, only when visual acuity was light perception or below. The addition of systemic antibiotics did not have any benefits. Over the last 30 years, however, surgical techniques have continued to evolve and the medicinal options have also been expanded. Moreover, the EVS examined only endophthalmitis after cataract surgery and strictly speaking the results cannot be transferred to endophthalmitis from other causes. OBJECTIVE This review discusses the current evidence for the different treatment modalities of the most important types of postoperative endophthalmitis. CONCLUSION The EVS provided important guidelines for the initial management of endophthalmitis and these guidelines remain relevant to this day; however, in view of the refinement of surgical techniques, novel treatment options, especially the nowadays continuously growing number of intravitreal injections and even some new antibiotics, it would be desirable if new controlled trials addressing the treatment of endophthalmitis would be performed.

Abstract
Bacillus cereus (B. cereus) endophthalmitis is a devastating intraocular infection primarily associated with post-traumatic injuries. The majority of these infections result in substantial vision loss, if not loss of the eye itself, within 12-48 h. Multifactorial mechanisms that lead to the innate intraocular inflammatory response during this disease include the combination of robust bacterial replication, migration of the organism throughout the eye, and toxin production by the organism. Therefore, the window of therapeutic intervention in B. cereus endophthalmitis is quite narrow compared to that of other pathogens which cause this disease. Understanding the interaction of bacterial and host factors is critical in understanding the disease and formulating more rational therapeutics for salvaging vision. In this review, we will discuss clinical and research findings related to B. cereus endophthalmitis in terms of the organism's virulence and inflammogenic potential, and strategies for improving of current therapeutic regimens for this blinding disease.

Abstract
Bacterial infection of the posterior segment of the eye (endophthalmitis) leads to a robust host response that often results in irreversible damage to the layers of the retina, significant vision loss, and in some patients, enucleation of the globe. While a great deal of effort has gone into understanding the role of bacterial virulence factors in disease initiation and propagation, it is becoming increasingly clear that the host response to infection plays a major role in causing the damage associated with endophthalmitis. Researchers have identified the host receptors which detect infecting organisms and initiate the cascade of events that result in inflammation. This inflammation may damage nonregenerative tissues of the eye while attempting to clear the infection. Both Gram-positive and Gram-negative bacteria can cause endophthalmitis. These organisms initiate an immune response by activating toll-like receptor (TLR) pathways. Once an inflammatory response is initiated, the expression of immunomodulators, such as proinflammatory chemokines and cytokines, affect the recruitment of PMNs and other inflammatory cells into the eye. We and others have reported that knockout mice that do not express specific inflammatory pathways and molecules have an attenuated response to infection and retain significant retinal function. These findings suggest that host immune mediators are important components of the response to infections in the posterior segment of the eye, and the timing and level of their production may be related to the severity of the damage and the ultimate visual outcome. If that is the case, a better understanding of the complex and often redundant role of these pathways and inflammatory mediators may identify host molecules as potential anti-inflammatory therapeutic targets. This review highlights potential anti-inflammatory targets during acute inflammation in endophthalmitis, compares and contrasts those with findings in other models of ocular inflammation, and translates current immunomodulatory strategies for other types of infection and inflammation to this blinding disease. Given the poor visual outcomes seen in patients treated with antibiotics alone or in combination with corticosteroids, immunomodulation in addition to antibiotic therapy might be more effective in preserving vision than current regimens.

Abstract
BACKGROUND Endophthalmitis refers to severe infection within the eye that involves the aqueous humor or vitreous humor, or both, and threatens vision. Most cases of endophthalmitis are exogenous (i.e. due to inoculation of organisms from an outside source), and most exogenous endophthalmitis is acute and occurs after an intraocular procedure. The mainstay of treatment is emergent administration of broad-spectrum intravitreous antibiotics. Due to their anti-inflammatory effects, steroids in conjunction with antibiotics have been proposed to be beneficial in endophthalmitis management. OBJECTIVES To assess the effects of antibiotics combined with steroids versus antibiotics alone for the treatment of acute endophthalmitis following intraocular surgery or intravitreous injection. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 11), MEDLINE Ovid (1946 to 8 December 2016), Embase Ovid (1980 to 8 December 2016), LILACS (Latin American and Caribbean Health Sciences Literature Database) (1982 to 8 December 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 8 December 2016, ClinicalTrials.gov (www.clinicaltrials.gov); searched 8 December 2016, and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 8 December 2016. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA We included randomized controlled trials comparing the effectiveness of adjunctive steroids with antibiotics alone in the management of acute, clinically diagnosed endophthalmitis following intraocular surgery or intravitreous injection. We excluded trials with participants with endogenous endophthalmitis unless outcomes were reported by source of infection. We imposed no restrictions on the method or order of administration, dose, frequency, or duration of antibiotics and steroids. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results, assessed risk of bias, and extracted data using methods expected by Cochrane. We contacted study authors to try to obtain missing information or information to clarify risk of bias. We conducted a meta-analysis for any outcomes that were reported by at least two studies. Outcomes reported from single studies were summarized in the text. We assessed the certainty of the evidence using GRADE. MAIN RESULTS We included three trials with a total of 95 randomized participants in this review and identified one ongoing trial. The studies were conducted in South Africa, India, and the Netherlands. Out of the 92 analyzed participants, 91 participants were diagnosed with endophthalmitis following cataract surgery. In the remaining participant, endophthalmitis was attributable to penetrating keratoplasty. All studies used intravitreous dexamethasone for adjunctive steroid therapy and a combination of two intravitreous antibiotics that provided gram-positive and gram-negative coverage for the antibiotic therapy. We judged one trial to be at overall low risk of bias and two studies to be at overall unclear risk of bias due to lack of reporting of study methods. None of the three trials had been registered in a clinical trial register.While none of the included studies reported the primary outcome of complete resolution of endophthalmitis as defined in our protocol, one study reported combined anatomical and functional success (i.e. proportion of participants with intraocular pressure of at least 5 mmHg and visual acuity of at least 6/120). Very low-certainty evidence suggested no difference in combined success when comparing adjunctive steroid antibiotics alone (risk ratio (RR) 1.08, 95% confidence interval (CI) 0.80 to 1.45; 32 participants). Low-certainty evidence from two studies showed that a higher proportion of participants who received adjunctive dexamethasone had a good visual outcome (Snellen visual acuity 6/6 to 6/18) at three months compared with those in the antibiotics-alone group (RR 1.95, 95% CI 1.05 to 3.60; 60 participants). Similarly, low-certainty evidence from one study suggested that more participants in the dexamethasone group had a good visual outcome at 12 months compared to those who did not receive dexamethasone (RR 2.00, 95% CI 0.98 to 4.08; 28 participants). Investigators of one study reported improvement in visual acuity, but we could not estimate the effect of adjunctive steroid therapy because the study investigators did not provide standard deviations or standard errors. Two studies reported adverse events (retinal detachment, hypotony, proliferative vitreoretinopathy, and seclusion of pupil). The total numbers of adverse events were 8 out of 30 (26.7%) for those who received dexamethasone versus 6 out of 30 (20.0%) for those who did not. We could only perform a pooled analysis for the occurrence of retinal detachment; any difference between the two treatment groups was uncertain (RR 1.57, 95% CI 0.50 to 4.90; 60 participants) (very low-certainty evidence). No study reported intraocular pressure or cost outcomes. AUTHORS' CONCLUSIONS Current evidence on the effectiveness of adjunctive steroid therapy versus antibiotics alone in the management of acute endophthalmitis after intraocular surgery is inadequate. We found no studies that had enrolled cases of acute endophthalmitis following intravitreous injection. A combined analysis of two studies suggests adjunctive steroids may provide a higher probability of having a good visual outcome at three months than not using adjunctive steroids. However, considering that most of the confidence intervals crossed the null and that this review was limited in scope and applicability to clinical practice, it is not possible to conclude whether the use adjunctive steroids is effective at this time. Any future trials should examine whether adjunctive steroids may be useful in certain clinical settings such as type of causative organism or etiology. These studies should include outcomes that take patient's symptoms and clinical examination into account, report outcomes in a uniform and consistent manner, and follow up at short- and long-term intervals.

Abstract
Ocular infection and inflammation are common and are associated with myriad ocular conditions ranging from mild disease to blinding conditions. There are numerous anti-invectives with spectra against inciting pathogens. Given the potential for ocular infections to rapidly progress initial broad spectrum therapy is usually required, with therapy tailored as microbiological identification and sensitivities become available. The emergence of antibiotic resistance has become a major health problem. Anti-inflammatory therapy can be institutes to prevent ocular symptoms and end-organ damage. A therapy should be selected which is potent enough to interrupt the inflammatory cascades in play, but which avoids potential side effects. Glucocorticoids, NSAIDs, and biological agents may be used singularly or in combination. New drug delivery devices may allow for better local treatment of chronic ocular inflammation.
