Topical antibiotic prophylaxis before intravitreal injections: a pilot study. Graefes Arch Clin Exp Ophthalmol 2023; 261:2953-2959. [PMID: 37199800 DOI: 10.1007/s00417-023-06113-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 04/21/2023] [Accepted: 05/10/2023] [Indexed: 05/19/2023] Open
Abstract
PURPOSE To explore whether topical antibiotic prophylaxis in patients scheduled for intravitreal injections achieves surface sterility in a greater proportion of subjects as compared to povidone-iodine alone. MATERIAL AND METHODS A randomized, triple-blind clinical trial. POPULATION patients scheduled for intravitreal injections for maculopathy. INCLUSION CRITERIA any sex and race, age 18 years and above. Subjects were randomized into 4 groups: the first group applied chloramphenicol (CHLORAM), the second netilmicin (NETILM), the third a commercial ozonized antiseptic solution (OZONE), and the fourth applied no drops (CONTROL). OUTCOME VARIABLE percentage of non-sterile conjunctival swabs. Specimens were collected before and after the application of 5% povidone-iodine moments before the injection. RESULTS Ninety-eight subjects (33.7% females, 64.3% males), mean age: 70.2 ± 9.3 years (54-91). Before povidone-iodine, both the CHLORAM and NETILM group showed a lower percentage of non-sterile swabs (61.1% and 31.3% respectively), as compared to the OZONE (83.3%) and CONTROL (86.5%) groups (p < .04). However, this statistical difference was lost after the application of povidone-iodine for 3 min. Percentage of non-sterile swabs in each group after applying 5% povidone-iodine: CHLORAM 11.1%, NETILM 12.5%, CONTROL 15.4%, OZONE 25.0%. This was not statistically significant (p > .05). CONCLUSIONS Topical antibiotic prophylaxis with chloramphenicol or netilmicin drops decreases the bacterial load on the conjunctiva. However, after the application of povidone-iodine, all groups showed a significant reduction in the percentage of non-sterile swabs, and this value was comparable among all groups. For this reason, authors conclude that povidone-iodine alone is sufficient and prior topical antibiotic prophylaxis is not indicated.

Topical Antibiotic Prophylaxis and Intravitreal Injections: Impact on the Incidence of Acute Endophthalmitis-A Nationwide Study in France from 2009 to 2018. Pharmaceutics 2022; 14:pharmaceutics14102133. [PMID: 36297568 PMCID: PMC9611403 DOI: 10.3390/pharmaceutics14102133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 09/27/2022] [Accepted: 09/28/2022] [Indexed: 11/07/2022] Open
Abstract
Background: The dramatic increase in intravitreal injections (IVTs) has been accompanied by a greater need for safer procedures. The ongoing debate about topical antibiotic prophylaxis after IVTs emphasizes the importance of large-scale studies. We aimed to study the role of topical antibiotic prophylaxis in reducing the risk of acute endophthalmitis after IVTs. Methods: Population-based cohort study, in France, from 2009 to 2018, including all French patients receiving IVTs of corticosteroids or anti-VEGF agents. Results: A total of 5,291,420 IVTs were performed on 605,434 patients. The rate of topical antibiotic prophylaxis after IVTs progressively decreased during the study period, with a sharp drop in 2014 (from 84.6% in 2009 to 27.4% in 2018). Acute endophthalmitis occurred in 1274 cases (incidence rate = 0.0241%). Although antibiotic prophylaxis did not alter the risk of endophthalmitis (p = 0.06), univariate analysis showed an increased risk after fluoroquinolone and aminoglycoside prophylaxis. This increased risk was not found in multivariate analysis. However, we observed an increased risk related to the use of fixed combinations of fluoroquinolones and aminoglycosides with corticosteroids (IRR = 1.89; 95% CI = 1.57–2.27%, antibiotics combined with corticosteroids). Conclusion: These results are consistent with the literature. Endophthalmitis rates after IVTs did not decrease with topical antibiotic prophylaxis. The use of a combination of antibiotics and corticosteroids doubles the risk of endophthalmitis and should be avoided. Avoiding antibiotic prophylaxis would reduce the costs and the potential risks of antibiotic resistance.

Design, construction and in vivo functional assessment of a hinge truncated sFLT01. Gene Ther 2022; 30:347-361.

Abstract
Gene therapy for the treatment of ocular neovascularization has reached clinical trial phases. The AAV2-sFLT01 construct was already evaluated in a phase 1 open-label trial administered intravitreally to patients with advanced neovascular age-related macular degeneration. SFLT01 protein functions by binding to VEGF and PlGF molecules and inhibiting their activities simultaneously. It consists of human VEGFR1/Flt-1 (hVEGFR1), a polyglycine linker, and the Fc region of human IgG1. The IgG1 upper hinge region of the sFLT01 molecule makes it vulnerable to radical attacks and prone to causing immune reactions. This study pursued two goals: (i) minimizing the immunogenicity and vulnerability of the molecule by designing a truncated molecule called htsFLT01 (hinge truncated sFLT01) that lacked the IgG1 upper hinge and lacked 2 amino acids from the core hinge region; and (ii) investigating the structural and functional properties of the aforesaid chimeric molecule at different levels (in silico, in vitro, and in vivo). Molecular dynamics simulations and molecular mechanics energies combined with Poisson-Boltzmann and surface area continuum solvation calculations revealed comparable free energy of binding and binding affinity for sFLT01 and htsFLT01 to their cognate ligands. Conditioned media from human retinal pigment epithelial (hRPE) cells that expressed htsFLT01 significantly reduced tube formation in HUVECs. The AAV2-htsFLT01 virus suppressed vascular development in the eyes of newborn mice. The htsFLT01 gene construct is a novel anti-angiogenic tool with promising improvements compared to existing treatments.

Abstract
BACKGROUND AND OBJECTIVE To evaluate rates of suspected endophthalmitis following intravitreal injections of aflibercept, bevacizumab, ranibizumab (vial and pre-filled), dexamethasone implant, and triamcinolone in clinical practice. PATIENTS AND METHODS Retrospective study of aggregated electronic medical records from the Vestrum Health Database. Eyes with a diagnosis of suspected endophthalmitis based on billing codes between January 2013 and June 2019 were included. RESULTS Total number of injections, suspected endophthalmitis cases, and medication rate, respectively, were: aflibercept (1,412,699; 687; 0.049%); bevacizumab (1,467,722; 379; 0.026%); ranibizumab vial (884,061; 233; 0.026%), ranibizumab pre-filled (427,763; 96; 0.022%); dexamethasone implant (49,464; 53; 0.107%); and triamcinolone (75,038; 110; 0.147%). Rates were lower for bevacizumab and ranibizumab (vial and pre-filled) compared to aflibercept, dexamethasone implant, and triamcinolone (P < .05). Triamcinolone had a higher rate compared to all of the other medications (P < .05). CONCLUSIONS Suspected endophthalmitis rates following anti-vascular endothelial growth factor injections in clinical practice were similar to reported rates in clinical trials. Rates of suspected endophthalmitis following steroid injections trended higher with significantly higher rates with triamcinolone. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:312-318.].

Abstract
Purpose To report technique preferences for intravitreal injections among retina specialists in Mexico. Methods Cross-sectional survey. Ophthalmologists with a two-year retina training, active members of the Mexican Retina Association, were contacted through email to answer a survey consisting of 37 items regarding their IVI application technique. Results A total of 133 retina specialists participated, with a response rate of 78%. Forty-five percent applied the intravitreal injections in an operating room designated for the procedure. Sixty-three percent reported never injecting both eyes on the same day. Ninety-six percent wore a face mask during the procedure and 91% wore gloves. Eighty-two percent used a lid speculum. Tetracaine drops were the anesthetic method employed by 97% of participants. All participants utilized povidone-iodine for antisepsis. Eighty percent measured the puncture site with a caliper. Superotemporal quadrant was the one chosen to place the injection by 63% of participants. Fifty-nine percent indicated post-injection antibiotic drops for several days. Post-injection counting fingers visual acuity was verified by 53% of the participants. Fifty-six percent of the participants placed an eye-patch after the procedure. Conclusion There are different practices regarding the application of intravitreal injections among retina specialists in Mexico. Performing this type of survey periodically could show changes in preferences, as new evidence is incorporated into clinical practice.

Abstract
Purpose We sought to determine changes in the conjunctival bacterial flora and antibiotic resistance after topical antibiotic drops for infection prophylaxis were administered following intravitreal injections in patients with type 2 diabetes. Methods This prospective and nonrandomized cohort study included 116 eyes of 116 treatment-naive patients with type 2 diabetes who received six serial intravitreal anti-vascular endothelial growth factor injections for macular edema. Three conjunctival cultures were obtained from each eye over the course of the study (Culture 1, baseline; Culture 2, 1 month after the third injection; and Culture 3, 1 month after the sixth injection). The study subjects were given topical moxifloxacin hydrochloride for 4 days after each monthly intravitreal injection. The growth patterns of conjunctival bacterial flora and the antibiotic resistance to several commonly used antibiotics were examined. Results The rate of culture positivity increased significantly during the observation period (Culture 1, n = 47, 40.5%; Culture 2, n = 58, 50%; Culture 3, n = 76, 65.5%, p < 0.001). The bacterium with the highest baseline culture positivity was Staphylococcus epidermidis (n = 45, 38.8%), which increased significantly during the observation period (p < 0.001). No significant increase was noted in the culture positivity of the other bacteria with baseline culture positivity (p > 0.05). Regarding antibiotic susceptibility, significant increases in resistance to the fluoroquinolone group of drugs were noted (p < 0.001). No significant changes in sensitivity were detected in the other 11 investigated antibiotics that are commonly used in clinical practice (p > 0.05). Conclusions The use of topical moxifloxacin after each intravitreal injection significantly increases the fluoroquinolone resistance of the ocular surface flora and the culture-positivity rate of S. epidermidis in patients with type 2 diabetes.

Abstract
OBJECTIVE To review the literature on noninfectious endophthalmitis (NIE) following intravitreal triamcinolone acetonide (IVTA). DESIGN A literature review and case report. PARTICIPANTS Individuals who developed NIE after IVTA injection. METHODS A review of the literature was undertaken using Ovid MEDLINE and EMBASE databases, and articles available up to and including December 30, 2019, were included. A total of 518 articles were identified, of which 27 were selected. We also present an illustrative case report. RESULTS The incidence rate of NIE lies between 0.1% and 7.3% in most studies. Although the etiology of NIE is still the subject of investigation, proposed mechanisms include excipients and rheologic stress caused by small crystals. The time to presentation of NIE is often 1-3 days after IVTA injection, with symptoms of moderate to marked reduction in visual acuity along with signs of anterior chamber inflammatory reaction, hypopyon, and vitritis. Resolution occurs in 1-3 weeks in the majority of patients, and almost all return to their pre-injection visual acuity. Differences in the presentations of NIE, infectious endophthalmitis, and pseudo-endophthalmitis are discussed. We also present an illustrative case report of an 80-year-old woman who developed NIE after an IVTA injection for cystoid macular edema. CONCLUSIONS It is important to distinguish NIE from other forms of endophthalmitis because they have different natural histories and require different interventions and follow-up. NIE is rarely accompanied by significant pain or conjunctival erythema. Visual acuity is inconsistently affected and is therefore not a good criterion for identifying the type of presenting endophthalmitis.

Abstract
An aging population leads to increasing demand for medical retina services with chronic diseases being managed in long-term care pathways. Many hospital services struggle to deliver efficient and effective MR care due, at least in part, to infrastructure that does not expand responsively enough to meet the increased demand. A steering committee of retinal specialists from a variety of UK NHS hospital ophthalmology departments with experience of leading and managing NHS retinal services in the intravitreal era came together for the generation of this document to review and compile key aspects that should be considered when optimising intravitreal treatment capacity within MR services. This article aims to provide a useful collation and signposting of key published evidence, consensus and insights on aspects of delivering an intravitreal service, including treatment regimens, virtual clinics, staff training and governance, telemedicine and information technology, and data collection and key performance indicators. The objective is to equip ophthalmologic healthcare professionals with the necessary tools to develop and adapt their local service in the face of current and projected increased demand.

Abstract
Backgound Intravitreal injections are the most common treatment modality for several retinal pathologies. Despite endophthalmitis being the most feared complication, antibioprophylaxis remains controversial in intravitreal injections. Methods This was a retrospective study done for a period of 2 years from 1st January 2017 to 31st December 2018 in B. P Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) among patients receiving intravitreal bevacizumab. The intravitreal injection was given by a single surgeon. It included 503 eyes which received intravitreal bevacizumab over a period of 2 years without pre and postoperative antibiotics. Results Out of 503 eyes studied over a period of 2 years without antibiotic prophylaxis the rate of endophthalmitis was 0.0019% which is very low compared to the other studies with rate of endophthalmitis between 0.019–0.09%. Conclusion The risk of endophthalmitis was low even without pre/post-operative antibiotics. Intravitreal injection can be given safely without pre-operative and post-operative antibiotics. Trial Registration not applicable as it is a retrospective study.

Abstract
PURPOSE The purpose was to compare the incidence of endophthalmitis after intravitreal injection with and without topical antibiotic prophylaxis. METHODS This is a single-center, retrospective case-control study. All patients treated with intravitreal injection of ranibizumab, bevacizumab, aflibercept, or corticosteroids for a variety of retinal vascular diseases between 1 October 2014 and 30 November 2018 were included. The total number of patients and injections were determined from a review of billing code and practice management records. Endophthalmitis cases were determined from billing records and then confirmed with chart review. A 24-month period when topical antibiotics were prescribed after intravitreal injection was compared with a 24-month period when topical antibiotics were not prescribed. RESULTS Between 1 October 2014 and 30 November 2018, a total of 33,515 intravitreal injections were performed and 13 cases of post-intravitreal injection endophthalmitis were identified (incidence rate of 0.0388%; 95% confidence interval, 0.0217%-0.0644%) or approximately 1 case for every 2578 intravitreal injections. Between 1 October 2014 and 31 October 2016, while topical antibiotic prophylaxis was used postoperatively, 14,828 intravitreal injections were performed and 5 cases of endophthalmitis were reported (0.0337%; 95% confidence interval, 0.0129%-0.0739%). Between 1 November 2016 and 30 November 2018, while no prophylaxis was used, 18,687 intravitreal injections were performed and 8 cases of endophthalmitis were identified (0.0428%; 95% confidence interval, 0.0202%-0.0808%). There were no statistical differences in the incidence rates between the two groups (p = 0.675). CONCLUSION The incidence rate of endophthalmitis in the group with topical antibiotic prophylaxis after intravitreal injection was similar to the group with no prophylaxis. Changing the current clinical practice to no antibiotic prophylaxis had no effect on the incidence of endophthalmitis.

Abstract
Intravitreal injections have become the most commonly performed ophthalmic procedure, transforming modern retina practice. Postinjection endophthalmitis, while rare, remains the most feared potential complication. Prophylaxis measures including topical antisepsis, hand hygiene, gloves, masks, and drapes have all been proposed to help prevent postinjection endophthalmitis; however, there remains significant variation in protocol, given the lack of agreement among retina specialists on which steps are crucial to prevent endophthalmitis. With millions of injections performed annually, collating data have helped us better understand risk factors for endophthalmitis after intravitreal injection. We summarize the consensus guidelines for intravitreal injection technique and comprehensively review the literature on prevention of postinjection endophthalmitis.

Abstract
PURPOSE To analyze practice patterns used for intravitreal injections (IVIs) by retinal specialists in the United States. DESIGN Cross-sectional online survey. PARTICIPANTS Retina specialists in the United States who responded to a web-based survey. METHODS Retinal specialists in the United States were contacted via e-mail to complete a web-based, anonymous, 24-question survey. Multivariate analysis was performed on a selected question of interest focused on choice of anesthetic used for IVI. MAIN OUTCOME MEASURES Differences in IVI practices, such as antibiotic preferences, and different odds of anesthetic use by demographic variables with 95% confidence intervals. RESULTS A total of 281 retinal specialists responded to the survey (17% response rate). Respondents' average age was 53 years, with an average of 20 years in practice. Respondents practiced in 42 states, with 90% practicing in an urban or suburban area. For anesthesia, 14% used a topical anesthetic with cotton swab compression, 27% used a subconjunctival anesthetic, and 31% used an anesthetic gel. Age, gender, geographic location, and practice setting did not seem to impact choice of anesthetic for IVI significantly. Sixty-six percent of respondents always use a lid speculum, 21% administer topical antibiotics before injection, 36% wear a mask, 73% wear gloves, and 45% always dilate the eyes before injection. Most respondents use a 30-gauge needle and inject in the inferior temporal quadrant (70%). Forty-five percent always perform bilateral injections the same day if indicated. After the injection, 14% administer post operative nonsteroidal anti-inflammatory drugs, 28% administer postoperative antibiotics, and 31% routinely check intraocular pressure after injection. CONCLUSIONS This study provided real-world trends in practices for IVI among retina specialists in the United States. In addition, age, gender, practice type, and geographic location did not influence anesthetic choice for IVI.

Abstract
BACKGROUND AND OBJECTIVE To report on the microbiology, management, and visual outcomes of intravitreal injection (IVI)-associated, culture-proven endophthalmitis. PATIENTS AND METHODS All patients seen at a tertiary referral center with culture-proven endophthalmitis associated with an IVI between June 2007 and July 2017 were included in this retrospective analysis. RESULTS Thirty-five patients with culture-positive endophthalmitis following IVI were identified. All gram-positive organisms (34 of 35) were susceptible to vancomycin. Cases due to pathogens associated with oral or respiratory flora were common (31.4%, n = 11), presented earlier (2.0 days vs. 4.6 days, P < .001), were more likely to undergo pars plana vitrectomy (81.8% vs. 25.0%, P = .002) and had worse visual acuity outcomes. CONCLUSION IVI-associated endophthalmitis pathogens and anti-microbial susceptibilities in the Pacific Northwest are similar to those reported from other geographic locations. Bacteria associated with the oral and respiratory flora are common isolates that result in a more aggressive course and worse visual outcomes. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:33-38.].

Abstract
There is increasing evidence that topical antibiotics, given before and/or after intravitreal injections, are ineffective in preventing endophthalmitis and are possibly harmful. In addition to the lack of efficacy and increased development of resistant organisms, the use of topical antibiotics adds significantly to the cost of delivering intravitreal therapy. Despite this, in many countries, it is still common practice to use pre- and/or postinjection topical antibiotics. This review outlines the general principles of effective antibiotic prophylaxis, and the evidence regarding topical antibiotic use as a prophylactic measure for endophthalmitis following intravitreal injections. A key distinguishing feature of intravitreal injections from most other invasive procedures is the fact that they are often repeated on multiple occasions to the same eye. Given the lack of evidence to support topical antibiotics as an effective method of prophylaxis for postinjection endophthalmitis, it appears that more widespread education of ophthalmologists is required to avoid continued inappropriate use. Revision of drug labels in some jurisdictions, and amendment of local/professional society guidelines, may be required to assist in achieving this goal. Emphasis should be placed on antisepsis and aseptic technique, which are the major proven methods of endophthalmitis prevention, rather than antibiotics.

Antibiotic prophylaxis for preventing endophthalmitis after intravitreal injection: a systematic review. Eye (Lond) 2018; 32:1423-1431. [PMID: 29891901 DOI: 10.1038/s41433-018-0138-8] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2017] [Revised: 12/26/2017] [Accepted: 02/19/2018] [Indexed: 12/31/2022] Open
Abstract
PURPOSE To assess the effect of topical antibiotic prophylaxis on the rate of post-operative endophthalmitis after intravitreal injection (IVI). METHODS We conducted a systematic review of studies comparing the rates of endophthalmitis in eyes receiving IVI of different drugs with and without topical antibiotic prophylaxis, by searching MEDLINE and EMBASE up to June 2016. The methodological quality of the included studies was assessed using the Cochrane Risk of Bias tool and the Risk Of Bias in Non-randomized Studies of Interventions (ROBINS-I) for randomized clinical trials (RCTs) and non-randomized studies, respectively. We used a random-effects meta-analysis to compute the odds ratio (OR) of endophthalmitis with antibiotic prophylaxis compared with no prophylaxis and conducted subgroup analyses to compare the efficacy of different regimens and classes of antibiotics on endophthalmitis rates. RESULTS We identified 1 randomized and 12 non-randomized studies that reported 74 cases of endophthalmitis in 147,203 IVIs using antibiotic prophylaxis compared with 55 cases in 211,418 IVIs with no prophylaxis. The overall OR of endophthalmitis for antibiotic prophylaxis vs. no prophylaxis was 1.33 (95% CI 0.75-2.38). Leave-one-out sensitivity analyses showed that the exclusion of the only study with a serious risk of bias significantly increased the risk of endophthalmitis in the antibiotic prophylaxis group compared with control (OR: 1.62, 95% CI: 1.17, 2.34). There was no difference in the endophthalmitis rate associated with any other factor analyzed, including type of antibiotic, type of drug injected, or antibiotic prophylaxis regimen. CONCLUSIONS Antibiotic prophylaxis does not reduce the rate of endophthalmitis following IVI and might potentially be associated with an increased risk of post-operative infection.

Abstract
PURPOSE To assess the effect of topical antibiotic prophylaxis on postoperative endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor agents. METHODS A systematic literature search was performed from inception to March 2016 using PubMed, Medline, Web of Science, Embase, and the Cochrane Library, to identify articles that reported cases of endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor agents. We used a pooled analysis to estimate the incidence of cases of endophthalmitis who developed after injections performed with and without topical antibiotic prophylaxis. We used regression analysis to explore the effects of study characteristics on heterogeneity. RESULTS From our search of electronic databases, we identified and screened 4,561 unique records. We judged 60 articles to have reported findings for cohorts of patients who met our inclusion criteria, (12 arms of randomized clinical trials, 11 prospective cohort studies, and 37 retrospective cohort studies), which included 244 cases of endophthalmitis and 639,391 intravitreal injections of anti-vascular endothelial growth factor agents. The final pooled estimate endophthalmitis proportions were 9/10,000 (95% confidence interval, 7/10,000-12/10,000) in the antibiotic-treated group and 3/10,000 (95% confidence interval, 2/10,000-5/10,000) in the untreated group. The estimated incidence of endophthalmitis with topical antibiotic prophylaxis was approximated three times the incidence without prophylaxis. Random effects regression showed that none of the study characteristics significantly affected the effect size in either group. CONCLUSION Topical antibiotic after intravitreal injection of anti-vascular endothelial growth factor agents is associated with a higher risk of endophthalmitis.

Abstract
PURPOSE To report the incidence and characteristics of endophthalmitis after intravitreal injections (IVI) of antivascular endothelial growth factor agents and triamcinolone acetonide. METHODS Patients' medical records were retrospectively reviewed from January 2009 to June 2016, and the incidence, risk factors, clinical and microbiological characteristics of post-IVI endophthalmitis were evaluated. RESULTS The total number of intravitreal injections given, which included ranibizumab, bevacizumab, and triamcinolone acetonide, was 20,566, of which 27 cases developed endophthalmitis, giving an overall incidence of 0.131%. Significant reduction (p < 0.003) in incidence of endophthalmitis was observed in patients who received prefilled compounded bevacizumab injections (0.050%) compared to multiple bevacizumab injections from a single vial (0.235%). In the triamcinolone acetonide group, the incidence was 0.26%. Staphylococcus species were isolated from 18 cases (67%), and all strains were sensitive to vancomycin. CONCLUSIONS Adherence to strict aseptic protocols and use of prefilled compounded bevacizumab injections reduces the rate of post-IVI endophthalmitis.

Abstract
A comparison of the cellular content of needle tip aspirates and entry sites after transconjunctival intravitreal injection (IVI) using different needle types was performed. White outbred rats and human cadaver eyes were used for IVI by hypodermic 27 gauge (G) and 30G needles, and spinal anesthesia Pencan 27G needles. Aspiration of vitreous for quantitative morphological and cell cultivation analysis, as well as cyto-histological analysis of aspirates and entry sites were carried out. The most common cells in the aspirates from all needle types were conjunctival epithelial-, ciliary body non-pigmented epithelial- and sclerocyte-like cells and granular proteins. Crystallized vitreous specimens were present in each aspirate. The entry sites of hypodermic needles showed marked trauma in all wall layers of rat and human eyes accompanied by cellular destruction and hemorrhages. Pencan 27G needle caused less tissue trauma with partial reposition of sclerocytes. Transconjunctival IVIs with hypodermic 27G and 30G, and Pencan 27G needles result in trauma of all layers of the eyeball. The possible consequences of cellular content being cut and injected into the eye, as well as the entry site wound shape deserve future consideration and improvements.

Abstract
PURPOSE To determine the rate of postintravitreal injection endophthalmitis and to assess microbiological features and outcomes with and without the use of peri-intravitreal injection topical ophthalmic antibiotics. METHODS Consecutive series of endophthalmitis cases retrospectively identified after intravitreal injection at a multicenter, retina-only referral practice (Retina Consultants of Houston) from January 1, 2011 to December 31, 2014. Prophylactic peri-intravitreal injection topical antibiotics were routinely used during the initial 12-month period (January 1, 2011-December 31, 2011) and not used in the final 24-month period (January 1, 2013-December 31, 2014). Main outcome measures were incidence of endophthalmitis, microbiology results, treatment strategies, and visual outcomes. RESULTS Of 90,339 intravitreal injections, 30 cases of endophthalmitis were identified (endophthalmitis rate = 0.033%; 95% confidence interval, 0.021-0.045%; or approximately 1 of 3,011 intravitreal injections). The most common organisms isolated were coagulase-negative staphylococci (n = 10, 33%), followed by Streptococcus mitis (n = 2, 7%). Fourteen cases (47%) were culture negative. Peri-intravitreal injection topical antibiotic prophylaxis did not decrease the rate of endophthalmitis (0.035% [95% CI, 0.007-0.064%] with antibiotic use versus 0.021% [95% CI, 0.008-0.033%] without antibiotic use; P = 0.261). CONCLUSION The risk of endophthalmitis after intravitreal injection remains low, with coagulase-negative staphylococci and Streptococcus mitis the most common bacterial isolates identified. Prophylactic peri-intravitreal injection topical ophthalmic antibiotic use did not decrease the endophthalmitis rate.

Abstract
PURPOSE To describe the microbiological profile and clinical outcome in the eyes with culture-proven exogenous endophthalmitis. METHODS A retrospective analysis of 495 eyes diagnosed as exogenous endophthalmitis was performed over a period of 10 years. In all, aseptically collected aqueous and vitreous aspirates were cultured for bacteria and fungus using standard microbiological techniques. Gram-stain and KOH preparation of the specimens were also performed. The antibiotic susceptibility testing for bacterial isolates was performed by Kirby-Bauer disk diffusion method. The treatment was modified according to the antibiotic sensitivity profile. The final clinical ocular condition was divided into improved, stable or deteriorated. RESULTS Of 148 culture-proven endophthalmitis eyes, 137 (92.57%) were referred from elsewhere, and 11 (7.43%) belonged to our institute. Aetiologically, 76 (51.35%) eyes were post-cataract surgery, 61 (41.22%) were post-traumatic, 5 (3.38%) eyes post-intravitreal anti-vascular endothelial growth factor injection, 5 associated with corneal diseases and 1 bleb-related endophthalmitis. In 31 (20.95%) eyes, primary intravitreal antibiotics were given outside. The cultures revealed monomicrobial growth in 92.57% (n = 137) and polymicrobial growth in 7.43% (n = 11). Among the bacteria (n = 121, 81.76%), Pseudomonas species dominated overall (n = 32, 27.11%) and post-operative (n = 26, 38.23%) endophthalmitis group. Staphylococcus epidermidis (n = 14, 28%) was prominent in post-traumatic endophthalmitis group. Ninety-two percent (n = 108 isolates) of bacteria were sensitive to vancomycin. In 78 (52.7%) eyes, the clinical ocular condition improved or remained stable while deteriorated in 51 (34.46%). CONCLUSION A bacterial predominance was observed among causative organisms of exogenous endophthalmitis with Pseudomonas species being the most common. The appropriate surgical intervention improved or stabilised the visual acuity in nearly 50% eyes.

Abstract
Purpose To report the occurrence and management of severe infectious scleritis in a 75 year-old woman following intravitreal ranibizumab injection. Observations A 75 year-old monocular woman receiving monthly intravitreal ranibizumab injection for wet age related macular degeneration in the left eye presented with severe dull pain, decreased vision, and scleral melt with discharge 2 weeks after her last injection. The dilated fundus exam was devoid of vitritis. The patient was admitted to our hospital for both diagnostic and therapeutic purposes. She was initially started on aggressive oral and topical antibiotics, but showed no significant improvement. The scleral cultures were positive for Pseudomonas aeruginosa. In view of the aggressive nature of her infection, intravenous antibiotics were added to the treatment regimen. The patient recovered her baseline visual function after two weeks of intravenous, oral and, topical antibiotics. Conclusions and importance To our knowledge, this is the first case of anterior infectious necrotizing scleritis secondary to Pseudomonas aeruginosa infection following intravitreal ranibizumab injection. Clinicians performing intravitreal injections should have a high index of suspicion for iatrogenic infections including scleritis and endophthalmitis, as these infections require aggressive topical and systemic antibiotics as well as possible hospitalization.

Abstract
PURPOSE To report the incidence of endophthalmitis, the clinical and microbiological aspects, after intravitreal (IVT) injection of anti-vascular endothelial growth factor. METHODS A chart review was performed of patients diagnosed with endophthalmitis after receiving IVT injections of bevacizumab (Avastin) and ranibizumab (Lucentis) presenting to King Khaled Eye Specialist Hospital (KKESH) from May 2006 to December 2012. Endophthalmitis was diagnosed clinically as an intraocular infection with vitreous involvement that required treatment with IVT antibiotics or had undergone pars plana vitrectomy (PPV) to remove the suspected microorganism. Main outcome measures were the incidence of endophthalmitis and the clinical and microbiological features. RESULTS Seven cases of endophthalmitis were identified, there was 1 (0.004%) case of endophthalmitis of 22674 IVT injections performed at KKESH. All cases were after IVT bevacizumab. Three (42.85%) cases were culture-positive and caused by Staphylococcus epidermidis. The initial management was vitreous tap and IVT injection of antibiotics followed by PPV in 6 (85.7%) cases. One (14.3%) case underwent evisceration. Visual acuity improved at last visit in only 2 (28.6%) cases. The rate of endophthalmitis was 0.0004% for bevacizumab. CONCLUSIONS The rate of endophthalmitis after IVT bevacizumab and ranibizumab was very low. We recommend following a standardized injection protocol, adherence to sterile techniques, and proper patient follow-up are determinant factors for low incidence rates. In addition, endophthalmitis after IVT bevacizumab and ranibizumab have poor visual outcomes despite prompt treatment.

Garg SJ, Dollin M, Hsu J, Storey P, Vander JF. Effect of a Strict 'No-Talking' Policy During Intravitreal Injection on Post-Injection Endophthalmitis. Ophthalmic Surg Lasers Imaging Retina 2016; 46:1028-34. [PMID: 26599245 DOI: 10.3928/23258160-20151027-07] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2015] [Accepted: 09/10/2015] [Indexed: 11/20/2022]
Abstract
BACKGROUND AND OBJECTIVE To report the effect of a "no-talking" policy during intravitreal injection (IVI) on post-injection endophthalmitis. PATIENTS AND METHODS Retrospective, comparative, consecutive case series of patients receiving IVI between Jan. 1, 2009, and Dec. 31, 2012. A 24-month "usual care" period was compared to a 24-month no-talking period, during which a strategy to further minimize speech during IVI was implemented. RESULTS During the usual care period, 47,155 IVIs were performed, with nine culture-positive cases (0.019%), including seven due to oral pathogens (0.015%). During the no-talking period, 82,658 IVIs were performed, with eight culture-positive cases (0.010%), including two due to oral pathogens (0.002%). The no-talking policy was associated with a decreased endophthalmitis risk (P = .004), including oral pathogen-associated endophthalmitis (P = .02). CONCLUSION This study demonstrates that a more stringent no-talking policy during IVI may reduce the risk of post-injection endophthalmitis.

Abstract
Purpose The purpose of this study was to describe antivascular endothelial growth factor intravitreal injection techniques of retinal specialists in order to establish a cornerstone for future practice guidelines. Methods All members of the Israeli Retina Society were contacted by email to complete an anonymous, 19-question, Internet-based survey regarding their intravitreal injection techniques. Results Overall, 66% (52/79) completed the survey. Most (98%) do not instruct patients to discontinue anticoagulant therapy and 92% prescribe treatment for patients in the waiting room. Three quarters wear sterile gloves and prepare the patient in the supine position. A majority (71%) use sterile surgical draping. All respondents apply topical analgesics and a majority (69%) measure the distance from the limbus to the injection site. A minority (21%) displace the conjunctiva prior to injection. A majority of the survey participants use a 30-gauge needle and the most common quadrant for injection is superotemporal (33%). Less than half routinely assess postinjection optic nerve perfusion (44%). A majority (92%) apply prophylactic antibiotics immediately after the injection. Conclusion The majority of retina specialists perform intravitreal injections similarly. However, a relatively large minority performs this procedure differently. Due to the extremely low percentage of complications, it seems as though such differences do not increase the risk. However, more evidence-based medicine, a cornerstone for practice guidelines, is required in order to identify the intravitreal injection techniques that combine safety and efficacy while causing as little discomfort to the patients as possible.

PLoS One 2016; 11:e0156431. [PMID: 27257676 PMCID: PMC4892688 DOI: 10.1371/journal.pone.0156431] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2016] [Accepted: 05/13/2016] [Indexed: 12/13/2022] Open
Abstract
Despite endophthalmitis being the most feared complication, antibioprophylaxis remains controversial in intravitreal injections. Therefore, we conducted a systematic review and meta-analysis on the effects of antibioprophylaxis in intravitreal injections in the prevention of endophthalmitis. The PubMed, Cochrane Library, Embase and Science Direct databases were searched for studies comparing groups with and without antibiotics in intravitreal injection, with the use of the following keywords: "antibiotic*", "endophthalmitis" and “intravitreal injection*”. To be included, studies needed to specify number of participants and number of endophthalmitis within each group (with and without antibiotics). We conducted meta-analysis on the prevalence of clinical endophthalmitis including both culture-proven and culture negative samples. Nine studies were included. A total of 88 incidences of endophthalmitis were reported from 174,159 injections (0.051% i.e., one incidence of endophthalmitis for 1979 injections). Specifically, 59 incidences of endophthalmitis were reported from 113,530 injections in the group with antibiotics (0.052% or one incidence of endophthalmitis for 1924 injections) and 29 incidences of endophthalmitis from 60,633 injections in the group without antibiotics (0.048% or one endophthalmitis for 2091 injections). Our meta-analysis did not report a significant difference in the prevalence of clinical endophthalimitis between the two groups with and without topical antibiotics: the odds ratio of clinical endophthalimitis was 0.804 (CI95% 0.384–1.682, p = 0.56) for the antibiotic group compared with the group without antibiotics. In conclusion, we performed the first large meta-analysis demonstrating that antibioprophylaxis is not required in intravitreal injections. Strict rules of asepsis remain the only evidence-based prophylaxis of endophthalmitis. The results support initiatives to reduce the global threat of resistance to antibiotics.

Abstract
There has been a rapid rise in the use of intravitreal injections, such as anti-vascular endothelial growth factor (anti-VEGF) agents, performed over the past few years for the treatment of ocular neovascular diseases. This study aims to review the systemic and ocular adverse events among patients treated at a tertiary eye center over a period of 8 years. A retrospective review of all intravitreal injections of anti-VEGF performed over an 8-year period at a tertiary eye care center in Singapore was done. We report the frequency of systemic and ocular adverse events and compared it among the various anti-VEGF agents. A total of 14 001 intravitreal injections were performed on 2225 patients from January 1, 2007 to December 31, 2014, and this included 9992 bevacizumab (71.4 %), 3306 ranibizumab (23.6 %) and 703 aflibercept (5.0 %) injections. Systemic complications related to treatment were 26 (1.17 %) deaths (from any cause), of which 11 (0.49 %) were from fatal thromboembolic events, 7 (0.31 %) non-fatal thromboembolic events and two (0.09 %) serious non-ocular hemorrhage. Ocular complications included one (0.007 %) endophthalmitis, three (0.021 %) traumatic cataracts, and one (0.007 %) retinal detachment. Rates of death and thromboembolic events were similar among ranibizumab (lucentis), bevacizumab (avastin) and aflibercept (Eylea). The systemic and ocular complications associated with intravitreal injections among Asian patients at a tertiary eye center are relatively low and reflect the safety of the treatments.

Abstract
Endophthalmitis is an intraocular inflammatory condition which may or may not be caused by infective agents. Noninfectious (sterile) endophthalmitis may be attributable to various causes including postoperative retained soft lens matter or toxicity following introduction of other agents into the eye. Infectious endophthalmitis is further subdivided into endogenous and exogenous. In endogenous endophthalmitis there is hematogenous spread of organisms from a distant source of infection whereas in exogenous endophthalmitis direct microbial inoculation may occur usually following ocular surgery or penetrating eye injury with or without intraocular foreign bodies. Acute infective endophthalmitis is usually exogenous induced by inoculation of pathogens following ocular surgery, open-globe injury and intravitreal injections. More infrequently the infective source is internal and septicemia spreads to the eye resulting in endogenous endophthalmitis. Several risk factors have been implicated including immunosuppression, ocular surface abnormalities, poor surgical wound construction, complicated cataract surgery with vitreous loss and certain types of intraocular lens. Comprehensive guidelines and recommendations on prophylaxis and monitoring of surgical cases have been proposed to minimize the risk of acute endophthalmitis. Early diagnosis and prompt management of infective endophthalmitis employing appropriately selected intravitreal antibiotics are essential to optimize visual outcome.

Abstract
Purpose: Intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents including ranibizumab and aflibercept are used to treat patients with ocular disorders such as neovascular age-related macular degeneration (nAMD); however, the injections are associated with rare instances of severe ocular inflammation. This study compared severe ocular inflammation rates in patients treated with ranibizumab versus aflibercept.
Methods: United States physician-level claims data covering an 18-month period for each therapy were analyzed. The primary analysis compared severe ocular inflammation event rates per 1000 injections. Sensitivity and subgroup analyses evaluated the impact of factors including intraocular surgery, intravitreal antibiotic administration, and previous intravitreal injections.
Results: The analysis included 432,794 injection claims (ranibizumab n = 253,647, aflibercept n = 179,147); significantly, more unique severe ocular inflammation events occurred in patients receiving aflibercept than ranibizumab (1.06/1000 injections, 95% confidence interval [CI], 0.91–1.21, vs. 0.64/1000 injections, 95% CI 0.54–0.74; p < 0.0001). Comparable results were observed for analyses of patients who had undergone glaucoma or cataract surgeries, had antibiotic-associated endophthalmitis, had non-antibiotic-associated endophthalmitis, and were non-treatment-naive. In contrast, no significant differences in severe ocular inflammation claims were recorded in treatment-naive patients who had no record of anti-VEGF treatment in the 6 months preceding the index claim. No significant change occurred in the rate of severe ocular inflammation claims over time following ranibizumab treatment.
Conclusions: Severe ocular inflammation was more frequent following intravitreal injection with aflibercept than with ranibizumab during routine clinical use in patients with nAMD. This highlights the importance of real-world, post-approval, observational monitoring of novel medicines, and may aid clinical decision-making, including choice of anti-VEGF agent.

Abstract
Endophthalmitis remains a rare but important cause of visual loss. Prophylaxis strategies are important to reduce rates of endophthalmitis after cataract surgery, intravitreal injection, and other procedures. There is substantial variability between the US and the rest of the world. During cataract surgery, intracameral antibiotics are commonly used in many nations, especially in Europe, but are less commonly used in the US. A randomized clinical trial from the European Society of Cataract and Refractive Surgeons reported an approximately fivefold reduction in endophthalmitis rates associated with intracameral cefuroxime but these results are controversial. There are no randomized clinical trials regarding endophthalmitis associated with intravitreal injection. Topical antibiotics are commonly used in many nations, but are less commonly used in the US. At this time, there is no global consensus and it appears unlikely that additional major clinical trials will conclusively define the optimal endophthalmitis prophylaxis techniques.

Abstract
PURPOSE By optimizing the protocol for intravitreal injections, the risk of endophthalmitis can be minimized. This study assesses the incidence of endophthalmitis and other complications after a consecutive series of intravitreal injections where all antibiotics were excluded. METHODS Injections were performed from August 1, 1997 to October 31, 2012 in outpatient examination rooms at the Retina Center of Minnesota by a single retinal surgeon, the lead author. Most injections were performed to treat exudative age-related macular degeneration. Other reasons included diabetic macular edema, cystoid macular edema because of retinal vein occlusions, cytomegalovirus retinitis, and severe uveitis. Injections were given with topical povidone-iodine, proparacaine, and tetracaine, a sterile eyelid speculum, and clean nonsterile gloves, but without any antibiotics. Data were retrospectively analyzed using billing codes from a computer database system. RESULTS A total of 18,839 injections were given. Of these, the following injections were administered: bevacizumab, 15,479 (82.16%); ranibizumab, 1,669 (8.86%); triamcinolone acetonide (Kenalog-40), 1,014 (5.38%); pegaptanib sodium, 370 (1.96%); aflibercept, 148 (0.79%); dexamethasone implant, 88 (0.47%); triamcinolone acetonide (Triesence), 32 (0.17%); dexamethasone, 29 (0.15%); and ganciclovir, 10 (0.05%). There was one case of postinjection endophthalmitis. The incidence of endophthalmitis per injection was 0.0053%. CONCLUSION A low incidence of endophthalmitis can be achieved when topical antibiotics are omitted.

Abstract
The purpose of this review is to report and summarize previously reported studies and assess many of the individual steps of the intravitreal injection procedure's possible effect on the prevention of endophthalmitis. The pooled endophthalmitis rate from 20 large retrospective case series of anti-VEGF injections was 144/510,396 (0.028%; 1/3,544). Injections may be performed in an office-based location or in an operating room (OR) and low rates of endophthalmitis can be achieved in either location with careful attention to asepsis. Pre- or post-injection topical antibiotics have not been shown to be effective, and could select for more virulent microorganisms. Povidone-iodine prior to injection is accepted as the gold-standard antiseptic agent, but aqueous chlorhexidine may be an alternative. Antisepsis before and after gel or subconjunctival anesthetic is suggested. The preponderance of Streptococcal infections after intravitreal injection is discussed, including the possible role of aerosolization, which can be minimized by using face masks or maintaining silence. As with other invasive procedures in medicine, the use of sterile gloves, following adequate hand antisepsis, may be considered. Control of the eyelashes and lid margin is required to avoid contamination of the needle, but this can be achieved with or without a speculum. Techniques to minimize vitreous reflux have not been shown to reduce the risk of endophthalmitis. Same day bilateral injections should be performed as two separate procedures, preferably using drug from different lots, especially when using compounded drugs.

Abstract
PURPOSE To report the incidence and characteristics of endophthalmitis after intravitreal injections of anti-vascular endothelial growth factor agents or corticosteroids and to describe the clinical and bacteriologic characteristics, management, and outcome of these eyes with acute endophthalmitis in France. DESIGN Retrospective, nationwide multicenter case series. METHODS From January 2, 2008 to June 30, 2013, a total of 316,576 intravitreal injections from 25 French ophthalmic centers were included. For each center, the number of intravitreal injections was determined using billing codes and the injection protocol was recorded. A registry and hospital records were reviewed to identify patients treated for endophthalmitis after injection during the same time period. The main outcome measures were the incidence of clinical endophthalmitis and visual acuity of endophthalmitis cases. RESULTS During the study period, 65 cases of presumed endophthalmitis were found, giving an overall incidence of 0.021% (2.1 in 10,000 injections) (95% confidence interval [CI], 0.016%-0.026%). The median number of days from injection to presentation was 4 [1-26] days. The most common symptom was vision loss. Bacterial identification was achieved in 43.4%. The most frequent pathogens were gram-positive bacteria (91.3%), including coagulase-negative Staphylococcus in 78.3%. Neither the interval between injection and presentation for endophthalmitis nor the clinical signs differentiated culture-positive from culture-negative cases. In multivariate analysis, the use of a disposable conjunctival mould assist device and the use of prophylaxis with an antibiotic or antiseptic were significantly associated with an increased incidence of endophthalmitis (P = .001). The majority of patients had worse visual acuity after 3 months of follow-up when compared with acuity before endophthalmitis. CONCLUSIONS The incidence of presumed endophthalmitis after intravitreal injections of anti-vascular endothelial growth factors or corticosteroids was low and the prognosis poor. Prevention and management remain challenging. It remains to be determined whether the findings of this study are relevant for other countries using different techniques for intravitreal injections.

Abstract
PURPOSE To review evidence and provide updated guidelines on intravitreal (IVT) injection technique and monitoring. METHODS A review of the published literature on IVT injection from 2004 to 2014 formed the basis for round table deliberations by an expert panel of ophthalmologists. RESULTS The dramatic increase in the number of IVT injections has been accompanied by a comparable increase in evidence surrounding IVT practice patterns and techniques. The expert panel identified a number of areas that have evolved since publication of the original IVT injection guidelines in 2004, the most notable of which were a lack of evidence to support the routine use of pre-, peri-, and postinjection antibiotics to reduce the risk of endophthalmitis, and the role of aerosolized droplets containing oral contaminants from the patient and/or providers as a potential source of infection. The panel emphasized the continued importance of applying povidone-iodine to and avoiding eyelid contact with the intended injection site and needle. CONCLUSION Updated guidelines on IVT injection technique and monitoring are proposed based on a review of published literature and expert panel deliberations.

Abstract
PURPOSE The purpose of this study was to evaluate the effect of prophylactic topical antibiotics on bacterial resistance patterns in endophthalmitis following intravitreal injection of anti-vascular endothelial growth factor (VEGF) medications. METHODS In this retrospective case-control study, billing records and an infection log were used to identify all cases of endophthalmitis following intravitreal injection of ranibizumab, bevacizumab, or aflibercept between January 1, 2009 and September 30, 2013 at a single retina practice. A 28-month period when topical antibiotic drops were prescribed for use four times a day for 4 days following intravitreal injection was compared to a 21-month period when topical antibiotics were not prescribed. Patients treated during an 8-month transition period were excluded as prescription practices were changed. RESULTS During the study period, a total of 172,096 anti-VEGF injections were performed. During the period when antibiotics were prescribed, 28 cases of suspected infectious endophthalmitis occurred from a total of 57,654 injections, ten of which were culture-positive. During the period when antibiotics were not used, 24 cases of suspected endophthalmitis occurred from a total of 89,825 injections, six of which were culture-positive. During the antibiotic period, four of the ten (40 %) culture-positive cases grew bacteria resistant to the prescribed prophylactic antibiotics. In contrast, none of the six culture-positive cases grew bacteria resistant to those antibiotics during the period when antibiotics were not used (odds ratio = 9.0; 95 % confidence interval = 0.40-203.3; p = 0.17). CONCLUSIONS The use of prophylactic topical antibiotics following intravitreal injection may lead to higher rates of antibiotic-resistant bacteria in culture-positive endophthalmitis cases.

Abstract
Purpose To report on endophthalmitis occurrence and associated risk factors following the intravitreal injection of anti-VEGF agents based on a review of published literature. Materials and methods A Medline search was performed using the terms “bevacizumab” and “ranibizumab”. A total of 534 English-language articles of varying design and published from 2006 to November 2013 were analyzed for endophthalmitis occurrence and contributing perioperative factors. Results A total of 445,503 injections were counted. There were 103 cases of postinjection endophthalmitis in 176,124 injections (0.058%) with bevacizumab (Avastin) versus 79 cases in 269,379 injections (0.029%) with ranibizumab (Lucentis). This difference was due to a significantly higher occurrence of culture-negative endophthalmitis associated with bevacizumab injections. Culture-positive risk was not statistically different between the two drugs. The reported use of postinjection topical antibiotics increased the risk of culture-positive endophthalmitis. No association was found with the use of povidone iodine, a lid speculum, a mask, or an operating room. Streptococcus spp. were the most prevalent causative organism, accounting for nine of 54 (17%) of all culture-positive cases. Conclusion Reported postinjection endophthalmitis occurred significantly more in patients treated with bevacizumab than those treated with ranibizumab. However, culture-positive occurrence was similar. Despite the potential for contamination at the time of drug compounding, bevacizumab does not appear to confer a higher risk of culture-positive endophthalmitis than ranibizumab. This study also suggests antibiotic use may increase endophthalmitis occurrence.

Abstract
PURPOSE Endophthalmitis is a potentially blinding intraocular infection that requires urgent intervention. Self-inflicted endophthalmitis is rare, difficult to diagnose, and requires a multidisciplinary approach for management. The purpose is to present a rare case of sequential self-inflicted acute endophthalmitis as a feature of Munchausen syndrome. METHODS This is a case report reviewing imaging and laboratory studies. RESULTS A 42-year-old female patient developed culture-proven acute endophthalmitis sequentially in both eyes with different bacterial strains. There was clear evidence of self-inflicted corneal puncture tracks in the right eye, and during the course of inpatient psychiatric evaluation, the patient admitted to self-inflicted ocular perforations. CONCLUSION Patients with Munchausen syndrome often injure themselves as a method of drawing attention, sympathy, or reassurance. Although ocular injuries due to psychiatric disease are known to occur, intraocular injection as a mode of self-injury is extremely rare. A high index of suspicion must be maintained when the reported history and clinical course are inconsistent.

Abstract
PURPOSE To evaluate and to compare the safety of intravitreal ranibizumab injections performed by physicians and nurses at a single large hospital clinic in Denmark during 5 years. DESIGN Retrospective, interventional, non-comparative study. METHODS SETTING All eyes that underwent a protocolized ranibizumab injection procedure performed in an operating room mainly by nurses and physicians in their first year of ophthalmology training. STUDY POPULATION A total of 4623 eyes in 3679 patients with subretinal neovascularization secondary to a variety of retinal diseases, mainly neovascular AMD treated with intravitreal therapy (IVT) at the Glostrup Hospital from January 1, 2007 to December 31, 2011 with a mean follow-up of 12.2 months (95% confidence interval: 11.9-12.6). MAIN OUTCOME MEASURES Frequency of endophthalmitis, traumatic cataract, intraocular haemorrhage and retinal detachment from 2007 to 2012. RESULTS Overall, 38,503 intravitreal ranibizumab injections were performed in 4623 eyes. Injections were performed by nurses (32.5%), ophthalmology residents (61.3%) and vitreoretinal surgeons (6.2%). Severe complications to treatment were observed in 17 eyes: Endophthalmitis (14 eyes, 0.36 ‰ of injections whereof seven cases were culture-positive), anterior uveitis (one eye, 0.026 ‰), traumatic cataract (one eye, 0.026 ‰) and rhegmatogenous retinal detachment (one eye, 0.026 ‰). Retinal pigment epithelial tears were registered in 14 eyes in 14 subjects within the first year of treatment with ranibizumab. Of the 14 cases of endophthalmitis, seven occurred within a period of 5 weeks in 2010 when occasionally abnormal needle outflow resistance prompted the needle replacement in the operating room. No drug-related adverse events were recorded. CONCLUSIONS Intravitreal ranibizumab injection performed by nurses and physicians without preinjection topical antibiotics was associated with a rate of injection-related adverse events of 0.44 ‰.

Abstract
OBJECTIVE To describe the incidence and outcomes of endophthalmitis after intravitreal injections of anti-vascular endothelial growth factor agents in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT) and to assess the effect of prophylactic topical antimicrobials on incidence. DESIGN Cohort study within a randomized clinical trial. PARTICIPANTS Patients enrolled in CATT. METHODS Patients with neovascular age-related macular degeneration received intravitreal injections of ranibizumab or bevacizumab under 1 of 3 dosing regimens. The study protocol specified preinjection preparation to include use of a sterile lid speculum and povidone iodine (5%). Use of preinjection and postinjection antibiotics was at the discretion of the treating ophthalmologist. Patients were followed up monthly for 2 years. MAIN OUTCOME MEASURES Development of endophthalmitis and visual acuity. RESULTS Endophthalmitis developed after 11 of 18 509 injections (1 per 1700 [0.06%]; 95% confidence interval, 0.03%-0.11%), and in 11 of 1185 patients (0.93%; 95% confidence interval, 0.52-1.66). Incidence of endophthalmitis was 0.15% among injections with no antibiotic use, 0.08% among injections with preinjection antibiotics only, 0.06% among injections with postinjection antibiotics only, and 0.04% among injections with preinjection and postinjection antibiotics (P = 0.20). All eyes were treated with intravitreal antibiotics and 4 underwent vitrectomy. Among the 11 affected eyes, the final study visual acuity was 20/40 or better in 4 eyes (36%), 20/50 to 20/80 in 2 eyes (18%), 20/100 to 20/160 in 3 eyes (27%), and worse than 20/800 in 2 eyes (18%). The final visual acuity was within 2 lines of the visual acuity before endophthalmitis in 5 eyes (45%). CONCLUSIONS Rates of endophthalmitis were low and similar to those in other large-scale studies. Use of topical antibiotics either before or after injection does not seem to reduce the risk for endophthalmitis.

Abstract
PURPOSE To report the incidence, clinical features, microbiologic culture results, management and visual outcome of patients with endophthalmitis after intravitreal injections (IVTs). METHODS This retrospective chart review included all patients receiving IVTs between January 2005 and July 2012. Cases of suspected and confirmed endophthalmitis after IVT were identified and reviewed. RESULTS A total of 20,179 IVTs were perfomed during the study period. Six cases of supected endophthalmitis were identified clinically (0.03%), of which 3 were culture positive (0.015%). The risk of culture-positive post-IVT endophthalmitis was 2/8,882 (0.023%) in the 2005 to 2008 period and 1/11,297 (0.009%) in the period 2009 to 2012. Symptoms developed within the first 3 days after IVT in 4 of the 6 patients and visual acuity was reduced to hand motion in 4 of the 6 patients. Microbiologic specimens were positive on 3 of the 6 cases (coagulase-negative Staphylococcus, n = 2; Staphylococcus aureus, n = 1). Mean visual acuity before patients with endophthalmitis was 20/100, whereas mean final visual acuity at last follow-up was 20/200. CONCLUSION The incidence of endophthalmitis after IVT was low with no cases because of Streptococcus species in the present setting using povidone-iodine in the preoperative disinfection of the conjunctival sac. Therefore, adherence to standardized protocols including the use of povidone-iodine when performing IVTs is recommended.

Abstract
BACKGROUND Intravitreal injection has become a common procedure worldwide. A rare, but sight threatening, complication is bacterial endophthalmitis that has a poor visual prognosis. To identify practices that minimize the risk of endophthalmitis, the setting of a Danish University hospital is described. METHODS A review of the intravitreal injection database of the department. All injections were performed in a positive pressure ventilated operating room under sterile conditions. The treating physicians wore face mask, the conjunctiva was irrigated twice with 5% povidone-iodine preoperatively, and topical tobramycin was applied immediately after the injection. RESULTS The authors have performed a total of 20,293 injections were performed in 2,575 eyes. No cases of proven or suspected endophthalmitis were identified corresponding to a risk of 0% (95% confidence interval, 0-0.019) per injection and 0% (95% confidence interval, 0-0.15%) per patient. Approximately 7,000 injections, all in patients without diabetes, were treated without a course of topical antibiotics after the injection. CONCLUSION The department has had the lowest rate of endophthalmitis after intravitreal injections in the current literature. Several factors that could have contributed to the positive result are highlighted. Omitting a postoperative course of topical antibiotic appears safe in patients without diabetes.

Abstract
AIM To evaluate the effects of moxifloxacin exposure on the conjunctival flora and antibiotic resistance profile following repeated intravitreal injections. METHODS Seventy-two eyes of 36 patients [36 eyes in control group, 36 eyes in intravitreal injection (IVI) group] were enrolled in the study. All the eyes had at least one IVI and had diabetic macular edema (DME) or age-related macular degeneration (ARMD). Moxifloxacin was prescribed to all the patients four times a day for five days following injection. Conjunctival cultures were obtained from the lower fornix via standardized technique with every possible effort made to minimize contamination from the lids, lashes, or skin. Before the application of any ophthalmic medication, conjunctival cultures were obtained from both eyes using sterile cotton culture. An automated microbiology system was used to identify the growing bacteria and determine antibiotic sensitivity. RESULTS The bacterial cultures were isolated from 72 eyes of 36 patients, sixteen of whom patients (44.4%) were male and twenty (55.6%) were female. Average age was 68.4±9.0 (range 50-86). The average number of injections before taking cultures was 3.1+1.0. Forty-eight (66.7%) of 72 eyes had at least one significant organism. There was no bacterial growth in 8 (20.5%) of IVI eyes and in 16 (44.4%) of control eyes (P=0.03). Of the bacteria isolated from culture, 53.8% of coagulase negative staphylococci (CoNS) in IVI eyes and 47.2% CoNS in control eyes. This difference between IVI eyes and control eyes about bacteria isolated from culture was not statistically significant (P=0.2). Eleven of 25 bacteria (44.0%) isolated from IVI eyes and 11 (57.9%) of 19 bacteria isolated from control eyes were resistant to oxacillin. The difference in frequency of moxifloxacine resistance between two groups was not statistically significant (12.0% in IVI eyes and 21.1% in control eyes) (P=0.44). There were no cases of resistance to vancomycin, teicoplanin and linezolid. CONCLUSION There was no difference in species of bacteria isolated from cultures, or in the frequency of resistance to antibiotics between eyes that had recurrent IVI followed by moxifloxacin exposure compared with control eyes. However, the number of eyes that had bacterial growth was higher in IVI group than in the control group.

Abstract
BACKGROUND Intravitreal injections are the fastest growing cause of endophthalmitis and can result in severe vision loss. The prevention, diagnosis and management of such infections remain unclear and at times controversial. METHODS We searched Pubmed for keywords "prophylaxis," "endophthalmitis," "intravitreal injection." We focused on studies published in the last 2 years as well as other recent studies with particular attention to data on the incidence, microbiology, prevention, and treatment of injection-related endophthalmitis. RESULTS Over 20 relevant studies were found. With povidone-iodine preparation, the per-injection endophthalmitis rate is low at about 0.03%. Antibiotics do not appear to be beneficial for prevention of post-injection endophthalmitis. The best timing of vitrectomy is unclear. CONCLUSIONS Antibiotic prophylaxis is probably not needed when giving intravitreal injections. More data is needed to help determine the proper treatment for post-injection endophthalmitis.

Abstract
PURPOSE To report on the occurrence of endophthalmitis after intravitreal injections (IVI) in two different settings: office-based and operating room. METHODS Consecutive case series. Retrospective review of all patients who underwent IVI by 2 physicians between January 2009 and December 2011. Group A underwent IVI in the examination room in office-based setting and Group B underwent IVI in the operating room. RESULTS A total of 11,710 IVIs were performed during the study period. Group A: A total of 8,647 IVIs performed including 2,041 ranibizumab, 6,169 bevacizumab, and 437 triamcinolone acetonide. The diagnosis included neovascular age-related macular degeneration (5,376), diabetic macular edema (1,587), retinal vein occlusion (1,068), and miscellaneous diagnosis (616). Group B: A total of 3,063 IVIs performed including 683 ranibizumab, 2,364 bevacizumab, and 16 triamcinolone acetonide. The diagnosis included neovascular age-related macular degeneration (1,836), diabetic macular edema (771), retinal vein occlusion (189), and miscellaneous diagnosis (267). A total of 5 cases (0.043%) of clinically suspected endophthalmitis occurred in 11,710 injections. Three cases (0.035%) occurred in Group A, and 2 cases (0.065%) occurred in Group B. CONCLUSION The rate of clinically suspected endophthalmitis after IVIs is low whether the procedure is performed in the office or operating room setting. The findings have implications in terms of the patient convenience, efficiency, and cost of administrating these treatments.

Abstract
INTRODUCTION Endophthalmitis is the most dreaded complication after intravitreal injection. With the rise of antiangiogenics their rate is getting higher each year. The use of antibioprophylaxis is controversial. We tried to evaluate the impact of antibioprophylaxis on intravitreal injection endophthalmitis incidence. METHODS All patients who received intravitreal injections between January 2007 and October 2012 were included in this retrospective study. Until June 2012 all patients had antibiotics the days following the injection. From July 2012 the antibiotic was replaced by an antiseptic immediately after the injection. RESULTS An overall number of 11,450 injections were performed. The overall rate of endophthalmitis was 6/11,450 (0.052%). The incidence of endophthalmitis in the group with antibiotics was 3/10,144 injections (0.03%), 2 were culture proven (0.02%). The incidence in the group without antibiotics was 3/1306 (0.23%). The difference was significant (P=0.024). CONCLUSION The incidence of endophthalmitis post-intravitreal injections seems to be lower when using antibiotics. However, a prospective study is mandatory to draw more robust conclusions.

Abstract
PURPOSE To report conjunctival bacterial flora antibiotic resistance patterns after serial intravitreal injections performed using a povidone-iodine preparation without the use of preinjection or postinjection topical antibiotics. DESIGN Prospective, interventional case series. METHODS SETTING Single-center clinical practice in Pennsylvania. STUDY POPULATION Thirteen eyes of 13 treatment-naïve patients undergoing serial intravitreal anti-vascular endothelial growth factor (VEGF) injections for exudative age-related macular degeneration or macular edema attributable to retinal vein occlusion. INTERVENTION Conjunctival cultures from the treatment eye were performed prior to each injection preparation. A minimum of 3 monthly conjunctival cultures were obtained per eye over the course of the study. Ocular surface preparation consisted of topical anesthetic and povidone-iodine 5% without the use of preinjection or postinjection topical antibiotics. MAIN OUTCOME MEASURES Conjunctival flora growth patterns and antibiotic resistance patterns to several common antibiotics tested over the course of the study. RESULTS A total of 48 cultures were performed with a 77% culture positivity rate. Over the course of the serial conjunctival cultures in each patient, there was no evidence for emergence of resistant bacteria to any of the tested antibiotics (including fluoroquinolones and azithromycin) or significant alteration from baseline conjunctival flora. Of the 47 bacterial isolates, the most commonly isolated organism was coagulase-negative Staphylococcus both at baseline (73%) and following serial intravitreal injections (78%, P = .73). CONCLUSIONS Ocular surface preparation for intravitreal injection using povidone-iodine 5% alone in the absence of postinjection topical antibiotics does not appear to promote bacterial resistance or a discernible change in conjunctival flora.

Abstract
OBJECTIVE To compare the incidence of endophthalmitis after intravitreal injection with and without topical postinjection antibiotic prophylaxis. DESIGN Retrospective case-control study. PARTICIPANTS All patients treated with intravitreal injection of ranibizumab, bevacizumab, or aflibercept for a variety of retinal vascular diseases at a single, large retina practice between January 1, 2009, and October 1, 2012, were included. METHODS The total numbers of patients and injections were determined from a review of billing code and practice management records. Endophthalmitis cases were determined from billing records and from an infection log. All cases of endophthalmitis were confirmed with chart review. A 28-month period when topical antibiotics were prescribed after intravitreal injection was compared with a 9-month period when topical antibiotics were not prescribed. Patients treated during an 8-month transition period were excluded to allow for the conversion of antibiotic prescription practices. MAIN OUTCOME MEASURES Incidence of endophthalmitis, visual acuity outcomes, and microbial spectrum. RESULTS During the study period, a total of 117 171 intravitreal injections were performed (57 654 injections during the topical antibiotic period, 24 617 during the transition period, and 34 900 during the no-antibiotic period), with a total of 44 cases of suspected endophthalmitis (0.038%; 1 in 2663 injections), 17 of which showed culture-positive results (0.015%; 1 in 6892 injections). During the 28-month topical antibiotic period, there were 28 cases of suspected endophthalmitis (0.049%; 1 in 2059 injections), 10 of which showed culture-positive results (0.017%; 1 in 5765 injections). During the 9-month no-antibiotic period, there were 11 cases of suspected endophthalmitis (0.032%; 1 in 3173 injections), 4 of which showed culture-positive results (0.011%; 1 in 8725 injections). Topical antibiotic use was associated with a trend toward increased risk of suspected endophthalmitis (odds ratio [OR], 1.54; 95% confidence interval [CI], 0.77-3.10) and culture-positive endophthalmitis (OR, 1.51; 95% CI, 0.47-4.83). CONCLUSIONS The incidence of endophthalmitis after intravitreal injection is low. Using postinjection topical antibiotic drops does not reduce the risk of endophthalmitis developing and is associated with a trend toward higher incidence of endophthalmitis.

Abstract
PURPOSE To assess the rate of infectious endophthalmitis in a single clinical center in Iran and to compare the rate of endophthalmitis in patients receiving postinjection antibiotics with those who did not. METHODS A retrospective chart review of patients who received intravitreal injections of bevacizumab was undertaken. Cases of clinical diagnoses of endophthalmitis were reviewed. Bevacizumab was obtained at the time of injection from a commercially available vial after aseptic cleansing of the rubber cover. RESULTS Five patients (six eyes) developed clinical endophthalmitis after the intravitreal bevacizumab injection. The risk per injection was 0.10% (6/5,901). One culture-positive case was found overall. Postinjection antibiotic drops were prescribed for 68% of eyes. All endophthalmitis cases were among those who received postoperative antibiotic eye drops. The difference in the rates of endophthalmitis between those receiving postinjection antibiotics and those who did not was not statistically significant (P = 0.18). CONCLUSION A low risk of endophthalmitis consistent with the range of previous studies was observed notwithstanding the usage of multiple use of a single vial. Postinjection antibiotic drops may not be necessary.
