Objective:To investigate the related factors and prognosis of invasive Klebsiella pneumoniae liver abscess syndrome (IKLAS). Methods:The in-patients diagnosed with Klebsiella pneumoniae liver abscess in the Department of Infectious Diseases, Huashan Hospital, Fudan University from January 2015 to February 2021 were retrospectively enrolled. The patients were divided into IKLAS group and non-IKLAS group according to whether they had IKLAS or not. The clinical data between the two groups were compared, including the prevalence of diabetes mellitus, the details of liver abscess, clinical symptoms such as fever and abdominal pain, as well as laboratory tests such as glycosylated hemoglobin and hemoglobin. Statistical analysis was performed using chi-square test or independent sample t test. Multivariate logistic regression analysis was used to analyze the factors influencing the occurrence of IKLAS. Results:A total of 75 patients with Klebsiella pneumoniae liver abscess were enrolled, including 55 patients (73.33%) in the IKLAS group and 20 patients (26.67%) in the non-IKLAS group. Fifty-two point seven three percent (29/55) of the patients had diabetes mellitus and 12.73%(7/55) of the patients had abdominal pain in the IKLAS group, which were 20.00%(4/20) and 45.00%(9/20) in the non-IKLAS group, respectively, and the differences were both statistically significant ( χ2=6.38 and 7.28, respectively, both P<0.05). Most of liver abscesses were single (50/75, 66.67%), and more likely to occur in the right liver (50/75, 66.67%). The maximum diameter of liver abscess in the IKLAS group was (4.58±2.04) cm, which was smaller than that in the non-IKLAS group ((6.49±3.11) cm), and the difference was statistically significant ( t=2.82, P=0.011). Compared with those in the non-IKLAS group, patients in the IKLAS group had higher glycosylated hemoglobin (8.69%±2.64% vs 6.18%±1.31%) and hemoglobin ((112.25±22.04) g/L vs (100.05±18.59) g/L), and the differences were both statistically significant ( t=-4.25 and -2.21, respectively, both P<0.05). The proportion of patients using antibiotics combined with abscess drainage in the IKLAS group was 38.18%(21/55), and that in the non-IKLAS group was 85.00%(17/20). The difference between the two groups was statistically significant ( χ2=12.86, P<0.001). A total of 16 patients (21 eyes) were diagnosed as endogenous Klebsiella pneumoniae endophthalmitis (EKPE), and all of them were IKLAS patients, and 14 patients underwent monocular/binocular eyeball injection and/or vitrectomy and silicone oil filling. The visual acuity of 13 patients decreased significantly. Multivariate logistic regression analysis showed that complicated with diabetes mellitus was an independent risk factor for IKLAS (odds ratio ( OR)=5.02, 95% confidence interval (95% CI) 1.01 to 25.03, P=0.049). The large diameter of liver abscess was a protective factor for IKLAS ( OR=0.64, 95% CI 0.47 to 0.86, P=0.003). Conclusions:The patients with IKLAS have less abdominal pain, and most of them complicate with diabetes mellitus. Diabetes mellitus is an independent risk factor for the occurrence of IKLAS, while the large diameter of liver abscess is a protective factor. EKPE is associated with poor visual prognosis.

ABSTRACT Endophthalmitis is a severe form of purulent inflammation caused by the infection of the intraocular tissues or fluids. This infection infrequently occurs through endogenous routes, which are often correlated with major risk factors. Escherichia coli, a gram-negative rod, can cause endophthalmitis through hematogenous spread. We here report a 59-year-old man who presented to our service with acute visual impairment in his left eye, preceded by floaters. He was taking sirolimus and azathioprine for a transplanted kidney, had undergone catheterization for bladder atresia, and had a history of recurrent E. coli urinary tract infections. On evaluation, the left eye exhibited visual acuity of hand motion, anterior chamber reaction (3+/4+), and intense vitritis (4+/4+) with white flake clusters, which prevented appropriate retinal evaluation. Pars plana vitrectomy was performed, and the culture yielded E. coli. The present case highlights the importance of identifying the signs and symptoms of infection early so that diagnosis and treatment of endophthalmitis can be promptly initiated.

ABSTRACT Purpose: To describe the implementation pro cess and the preliminary results of a surveillance system for healthcare-associated endophthalmitis. Methods: This is a case study of the implementation of a surveillance system for healthcare-associated endophthalmitis. The system for healthcare-associated endophthalmitis is a structured system that enables surveillance of cases of healthcare-associated endophthalmitis after intraocular procedures, developed and coordinated by the Division of Hospital Infection at the State Health Department, São Paulo, Brazil. The implementation process included a pilot phase, followed by a scaling-up phase. Data were reported monthly to the Division of Hospital Infection by participating healthcare facilities that performed intraocular procedures in the state of São Paulo, Brazil, from September 2017 to December 2019. Results: Among the 1,483 eligible healthcare facilities, 175 engaged in the study (participation rate of 11.8%), reporting 222,728 intraocular procedures performed, of which 164,207 were cataract surgery and 58,521 were intravitreal injections. The overall incidence rate of endophthalmitis was reported to be 0.05% (n=105; 80 cases after cataract surgery and 25 cases after intravitreal injections). The incidence rates for healthcare facilities ranged from 0.02% to 4.55%. Most cases were caused by gram-positive bacteria, mainly Staphylococcus spp. In 36 (46.2%) of the cases, there was no bacterial growth; no sample was collected in 28 (26.7%) cases. This system for healthcare-associated endophthalmitis enabled the identification of an outbreak of four cases of endophthalmitis after intravitreal injections. Conclusion: The system for healthcare-associated endophthalmitis proved to be operationally viable and efficient for monitoring cases of endophthalmitis at the state level.

Conclusão: O sistema de vigilância epidemiológica para endoftalmites mostrou-se operacionalmente viável e eficiente para o monitoramento de casos de endoftalmite em nível estadual.
摘要
ABSTRACT The objective of this case report was to share the successful management of severe endophthalmitis, aiming at ocular integrity and visual acuity. A 73-year-old man presented with visual acuity of 20/30 in the right eye and 20/200 in the left eye. On the 21st day postoperatively after phacoemulsification in the left eye, he developed symptoms of endophthalmitis, including ocular discomfort, blurred vision, and whitish discharge. Despite negative cultures, his condition worsened, resulting in corneal perforation on the 31st day. Conjunctival flap and penetrating keratoplasty were performed. Currently, the patient maintains a visual acuity of 20/40 in the left eye, with a healthy graft and no signs of failure. Despite the complications, careful follow-up and timely interventions successfully preserved his vision. The use of conjunctival flap during the inflammatory phase was crucial to maintaining ocular integrity. This underscores the importance of different approaches in complex ocular complications, including alternative strategies for ocular protection during active inflammation.
RESUMO O objetivo deste relato de caso foi compartilhar o manejo bem-sucedido de uma grave endoftalmite, visando à integridade ocular e à acuidade visual. Um homem de 73 anos apresentou acuidade visual de 20/30 no olho direito e 20/200 no olho esquerdo. No 21° dia pós-operatório de facoemulsificação em olho esquerdo, ele desenvolveu sintomas de endoftalmite, incluindo desconforto ocular, visão embaçada e secreção esbranquiçada. Apesar de culturas negativas, sua condição piorou, resultando em perfuração corneal no 31° dia. A cobertura conjuntival e a ceratoplastia penetrante foram realizadas. Atualmente, o paciente mantém acuidade visual de 20/40 no olho esquerdo, com enxerto saudável e sem sinais de falha. Apesar das complicações, o acompanhamento cuidadoso e as intervenções oportunas preservaram a visão com sucesso. O uso de cobertura conjuntival durante a fase inflamatória foi crucial para manter a integridade ocular. Isso destaca a importância de diferentes abordagens em complicações oculares complexas, incluindo estratégias alternativas para proteção ocular durante a inflamação ativa.

Purpose: To assess the current trends in use of perioperative antibiotic prophylaxis, especially intracameral antibiotics (ICAB), for cataract surgery in India. Methods: This was an E?survey using a previously validated questionnaire carried out by the All India Ophthalmological Society (AIOS) in August 2022. An E?mail invitation to complete an online 40?point survey was sent to all members of the AIOS using a digital E?mail service (Survey Monkey) and social media platforms. Results: Out of 1804 total respondents, 58% (n = 1022) reported using routine ICAB prophylaxis. Of those using ICAB, 89% (n = 909) reported using it for all cases, whereas the rest used it for specific indications such as post?PC rent (n = 43), one eyed patient (n = 19), and high?risk cases (n = 50). Commercially available moxifloxacin was by far the commonest agent used for ICAB (n = 686, 67%). Eighty respondents (8%) reported noticing occasional toxic reactions and nontoxic corneal edema (n = 64, 6%) with ICAB. Surgeons with >10 years� experience especially practicing in medical colleges used fewer ICAB (OR = 0.52, 95%CI = 0.38 � 0.72, P < 0,001) compared to younger surgeons (<5?year experience) in solo clinics. The commonest reason for nonadoption of IC antibiotics was 搖nconvinced of the need to use it in my setting� (n = 296, 52% of those who answered this question). Conclusion: IC antibiotic prophylaxis for cataract surgery has significantly increased in India from 40% in 2017 to 58% in 2022. Commercially available moxifloxacin was preferred by the majority users. Intraocular inflammation may occur occasionally and needs safer formulations to avoid this

ABSTRACT Purpose: To present the results of a retrospective study regarding the clinical and economic impact of intracameral cefuroxime administration to prevent endophthalmitis during cataract surgery in a referral hospital. Methods: This study included 16,902 eyes from patients who had undergone cataract surgery between 2013 and 2017. From May 2014 onwards, all patients received routine intracameral injections of 1 mg cefuroxime (10 mg/1 mL) after phacoemulsification. The prophylactic efficacy was evaluated using the relative risk ratio, whereas the economic impact was evaluated using number needed to treat to avoid endophthalmitis. Results: Before introducing cefuroxime, 3,407 cataract surgeries were performed using the phacoemulsification technique, and 7 post-operatory cases of endophthalmitis occurred (0.2% incidence). After introducing the cefuroxime protocol, 13,495 surgeries were performed, and 4 endophthalmitis cases were registered (0.03% incidence). Cefuroxime was identified as a protective factor against the development of endophthalmitis [risk ratio = 14%, p=0.002, 95% confidence interval (CI) 95%, 4%-49%], with an economic impact of number needed to treat = 568. The potential savings with cefuroxime was approximately US $2,334.36 for every 568 patients treated. Conclusion: The incidence of endophthalmitis decreased by 86% (risk ratio = 14%, p=0.002, 95% CI, 4%-49%) after introducing intracameral cefuroxime prophylaxis at the study hospital. The results presented herein provide strong evidence for the use of cefuroxime in endophthalmitis prophylaxis after phacoemulsification surgeries, outperforming the alternative by providing both economic and clinical benefits.
RESUMO Objetivo: Apresentar os resultados de um estudo retrospectivo sobre o impacto clínico e econômico da administração de cefuroxima intracameral para prevenir endoftalmite nas cirurgias de catarata em um hospital de referência. Métodos: Este estudo incluiu 16.902 olhos de pacientes submetidos à cirurgia de catarata entre 2013 e 2017. A partir de maio de 2014, todos os pacientes receberam rotineiramente uma injeção intracameral de 1mg de cefuroxima (10mg/1mL) ao final da cirurgia de facoemulsificação. A eficácia da profilaxia foi avaliada usando o risco relativo e o impacto econômico foi avaliado com o número necessário para tratar para se evitar um caso de endoftalmite. Resultados: Antes da introdução do protocolo da cefuroxima, foram realizadas 3.407 cirurgias de catarata por facoemulsificação e ocorreram 7 casos de endoftalmite pós-operatória (incidência de 0,2%). Após a introdução do protocolo da cefuroxima, foram realizadas 13.495 cirurgias e registrados 4 casos de endoftalmite (incidência de 0,03%). A cefuroxima foi um fator de proteção no desenvolvimento de endoftalmite (risco relativo = 14%, p=0,002, Intervalo de Confiança de 95% [IC 95%], 4% - 49%) e o impacto econômico do número necessário para tratar = 568. A economia potencial com a cefuroxima foi de aproximadamente US$ 2.334,36 para cada 568 pacientes tratados. Conclusão: A incidência de endoftalmite diminuiu 86% (risco relativo = 14%, p=0,002, IC 95% 4% - 49%) desde a introdução da profilaxia com cefuroxima intracameral no hospital do estudo. Os resultados apresentados mostram forte evidência para o uso da cefuroxima na profilaxia da endoftalmite após cirurgias de facoemulsificação, por proporcionar economia de custos e benefício clínico.
摘要
This case report describes three eyes of two patients, who were diagnosed to have endogenous fungal endophthalmitis post coronavirus disease 2019 (COVID-19) infection. Both patients underwent vitrectomy with intravitreal anti-fungal injection. Intra-ocular samples confirmed the fungal etiology by conventional microbiological investigations and polymerase chain reaction in both cases. The patients were treated with multiple intravitreal and oral anti-fungal agents; however, vision could not be salvaged.
摘要
ABSTRACT Staphylococcus hominis (S. hominis) is a coagulase-negative Staphylococci and an infrequent cause of endophthalmitis. Due to its ability to produce biofilm, especially in diabetic patients, strains may acquire antibiotic resistance. We present two cases of S. hominis endophthalmitis, one with acute endophthalmitis after intravitreal bevacizumab injection and one with chronic endophthalmitis following undiagnosed penetrating ocular trauma. Although there are only four published S. hominis endophthalmitis cases in the literature, to the best of our knowledge, there has been no previously published case after intravitreal bevacizumab.
RESUMO Staphylococcus hominis (S. hominis) é um estafilococo coagulase-negativo e uma causa pouco frequente de endoftalmite. Devido à sua capacidade de produzir biofilme, especialmente em pacientes diabéticos, cepas dessa bactéria podem adquirir resistência a antibióticos. Este relato apresenta dois casos de endoftalmite por S. hominis: um de endoftalmite aguda após injeção intravítrea de bevacizumabe e outro de endoftalmite crônica após trauma ocular penetrante não diagnosticado. Embora existam apenas quatro casos de endoftalmite por S. hominis publicados na literatura, até onde sabemos não houve nenhum caso publicado anteriormente após bevacizumabe intravítreo.
摘要
Introducción: La endoftalmitis posquirúrgica es la complicación más temida de la cirugía de catarata. Resulta potencialmente devastadora, puede amenazar seriamente la visión y tiene una incidencia estimada de entre 0,02 y 0,71 por ciento. Objetivo: Determinar la incidencia de endoftalmitis poscirugía de catarata y su comportamiento clínico. Métodos: Se realizó un estudio observacional, descriptivo y de corte transversal. Se revisaron 13 850 cirugías consecutivas de catarata realizadas en el Centro Oftalmológico del Hospital Universitario Clínico Quirúrgico "Arnaldo Milián Castro" de Villa Clara, Cuba. Resultados: La incidencia de endoftalmitis poscirugía de catarata en esta serie fue de 0,17 por ciento (IC 95 por ciento: 0,10-0,24 por ciento); 0,18 por ciento (IC 95 por ciento 0,11-0,25 por ciento) para extracción extracapsular del cristalino y sin incidencia en la facoemulsificación. La forma de presentación aguda fue más frecuente que la crónica; 0,13 por ciento (IC 95 por ciento: 0,07-0,19 por ciento) y 0,04 por ciento (IC 95 por ciento: 0,01-0,07 por ciento), respectivamente. Los hombres fueron más afectados que las mujeres y la edad media fue de 71,8 años. La forma aguda se presentó con una media de 5,1 días entre la cirugía y el inicio de los síntomas y la crónica con una media de 21,2 semanas. El 39,1 por ciento de los pacientes tuvo agudeza visual de percepción luminosa al momento del diagnóstico. Se reportó un crecimiento bacteriano en el 44,7 por ciento de las muestras, con una positividad en humor acuoso y vítreo del 42,1 por ciento y 47,4 por ciento, respectivamente. El Staphylococcus coagulasa negativo fue el germen más frecuente. Los antibióticos intravítreos más vitrectomía plana precoz fue la conducta terapéutica más empleada. Conclusiones: La incidencia de endoftalmitis poscirugía de catarata en esta serie está en el rango de lo reportado a nivel mundial. Se presenta comúnmente de forma aguda y con pobre agudeza visual. El agente etiológico aislado con más frecuencia fue el Staphylococcus coagulasa negativa(AU)
Introduction: Postoperative endophthalmitis is the most feared complication of cataract surgery. It is potentially devastating, can seriously threaten vision and has an estimated incidence of between 0.02 and 0.71 percent. Objective: To determine the incidence of endophthalmitis after cataract surgery and its clinical behavior. Methods: An observational, descriptive, cross-sectional, descriptive study was performed. Thirteen 850 consecutive cataract surgeries performed at the Ophthalmologic Center of the Clinical Surgical University Hospital "Arnaldo Milián Castro" of Villa Clara were reviewed. Results: The incidence of endophthalmitis after cataract surgery in this series was 0.17 percent (95 percent CI: 0.10-0.24 percent); 0.18 percent (95 percent CI: 0.11-0.25 percent) for extracapsular extraction of the crystalline lens and no incidence in phacoemulsification. The acute form of presentation was more frequent than the chronic form; 0.13 percent (95 percent CI: 0.07-0.19 percent) and 0.04 percent (95 percent CI: 0.01-0.07 percent), respectively. Males were more affected than females and the mean age was 71.8 years. The acute form occurred with a mean of 5.1 days between surgery and symptom onset and the chronic form with a mean of 21.2 weeks. Thirty-nine.1 percent of patients had visual acuity of light perception at the time of diagnosis. Bacterial growth was reported in 44.7 percent of the specimens, with positivity in aqueous and vitreous humor of 42.1 percent and 47.4 percent, respectively. Coagulase-negative Staphylococcus was the most frequent germ. Intravitreal antibiotics plus remission for early flat vitrectomy was the most commonly employed therapeutic behavior. Conclusions: The incidence of post cataract surgery endophthalmitis in this series is in the range of that reported worldwide. It commonly presents acutely and with poor visual acuity. The most frequently isolated etiologic agent was coagulase-negative Staphylococcus(AU)

BACKGROUND: Endophthalmitis is a serious infectious complication of cataract surgery, which may lead to vision loss. Aim: To evaluate the effectiveness of intracameral moxifloxacin in reducing endophthalmitis after cataract surgery in Chilean patients. MATERIAL AND METHODS: We reviewed all phacoemulsification surgeries performed between 2012 and 2020 at a public hospital. The use of intraoperative intracameral moxifloxacin and possible surgical complications were recorded. In patients with postoperative endophthalmitis, we reviewed their risk factors and clinical characteristics. RESULTS: In the study, 22,869 phacoemulsification surgeries were registered, with an annual average of 2,541. The use of prophylactic intracameral moxifloxacin started progressively in 2014. In 2018 it was used in 88% of the surgeries. Fifteen eyes evolved with postoperative endophthalmitis, but none of these surgeries used intracameral moxifloxacin. Five and seven cases occurred in 2012 and 2013, respectively. There was a trend favoring moxifloxacin use, as a preventive measure for endophthalmitis, but the difference between groups was not significant (p = 0.56). In the group with endophthalmitis, 33.3% of the eyes were from patients with type 2 diabetes mellitus, in 13.3% there was rupture of the posterior capsule and 60% of the eyes corresponded to female patients. Since 2018 there is no record of endophthalmitis after cataract surgery performed in this center. Conclusions: Intracameral moxifloxacin showed a tendency to reduce the frequency of endophthalmitis after phacoemulsification surgery, but a longer observation period is required to reach statistical significance, due to the low frequency of this complication.

Purpose: This study was conducted to describe and validate a novel inflammatory score (IS) system in the management of infectious endophthalmitis. Methods: This was a prospective comparative non?interventional observational study. The study included the patients with clinical signs and symptoms of acute post?cataract surgery endophthalmitis (surgery within 6 weeks) with visual acuity from 6/18 to light perception. IS was scored by the clinical picture at two?levels of four ocular tissues on a scale of 0 (normal) to 4 (severe). Four masked graders of different levels of experience evaluated slit?lamp photographs. The concordance correlation coefficient was assessed between the slit?lamp clinical grading and photographic grading. We measured the concordance correlation coefficient, Pearson’s correlation (indicating precision), and the bias correction factor (indicating the accuracy). Results: The study included 43 eyes of 43 patients. The concordance correlation coefficient was 0.99 (95% CI 0.995 to 0.998). Both Pearson’s correlation coefficient and the bias correction were 0.99. The interclass correlation coefficient (ICC) was measured. The intra?rater ICC was 0.833 with good agreement (95% CI, 0.711 to 0.906; P < 0.001). Inter?rater ICC for consistency was 0.92 (95% CI 0.87 to 0.95). Inter?rater ICC for absolute agreement was 0.86 (95% CI 0.66 to 0.93). Conclusion: Currently used IS scoring in the study is a reliable, reproducible, and easy?to?apply scale to measure inflammation severity in endophthalmitis. We propose that it can have applications in decision?making for primary treatment and monitoring progression in acute infectious endophthalmitis

AIM: To analyze the clinical characteristics and antibiotic sensitivity of traumatic endophthalmitis caused by Bacillus cereus and discuss the early diagnosis and treatment measures.METHODS: The data of 15 patients(15 eyes)with Bacillus cereus endophthalmitis admitted to the Eye Trauma Center of Shaanxi Provincial Eye Hospital from January 2019 to December 2021 were collected. The injury time, injury condition, preoperative visual acuity, corrected visual acuity in the last follow-up, operation method, bacterial culture and drug sensitivity test results were recorded.RESULTS: Among the 15 patients(15 eyes), 5 eyes with simple corneal perforating wound were treated with wound debridement and suture combined with intraocular antibiotic injection. And another 10 eyes with penetrating injuries combined with traumatic cataract and intraocular foreign bodies were treated with debridement, cataract extraction, removal of intraocular foreign bodies, vitrectomy combined with silicone oil tamponade and intraocular antibiotic injection. Among the 15 patients, 11 patients(73%)were treated effectively and the eyeball was preserved, and 4 patients(27%)were treated ineffectively and ocular evisceration was performed. Among the 11 patients with eyeball retention, 1(9%)had decreased vision, 1(9%)had unchanged vision, 4(36%)had improved vision by 1 level, and 5(45%)had improved vision by 2 levels, and the postoperative visual acuity was significantly improved. Correlation analysis showed that the course of disease was negatively correlated with corrected visual acuity(rs=-0.762, P=0.001). The cultures of vitreous humor and aqueous humor samples of patients were all grown in Bacillus cereus, and susceptibility tests were sensitive to vancomycin.CONCLUSIONS: Vancomycin is an effective drug for the treatment of Bacillus cereus endophthalmitis. Vitrectomy combined with silicone oil tamponade and intravitreal injection of vancomycin are effective method for the treatment of Bacillus cereus endophthalmitis.

Objective:To investigate the clinical settings, antibiotic susceptibilities, management and outcomes of streptococcal endophthalmitis.Methods:A retrospective observational case series study. Fifty six eyes of 56 patients diagnosed with streptococcal endophthalmitis in Eye & ENT Hospital, Fudan University from 2012 to 2022 were collected. The treatment followed the general principles of relevant guidelines, including pars plana vitrectomy (PPV), vitreous injection of antibiotics (IVI), vitreous injection of glucocorticoids and systemic application of antibiotics. The follow-up time was (11.9±17.0) months. Patients' clinical characteristics, pathogenic distribution and antibiotic susceptibilities, treatment and outcomes in their medical records were retrospectively collected and analyzed.Results:All 56 patients had monocular onset, including 39 (69.6%, 39/56) males and 17 (30.4%, 17/56) females, 26 (46.4%, 26/56) with left eyes involved and 30 (53.6%, 30/56) with right eyes involved. Their average age was (25.0±24.4) years. Ocular trauma was the leading cause of streptococcal endophthalmitis (73.2%, 41/56), followed by ophthalmic surgery (23.2%, 13/56) and endogenous infection (3.6%, 2/56). The streptococcal species included Streptococcus viridans (50.0%, 28/56), Streptococcus pneumoniae (18/56, 32.1%) and β-hemolytic Streptococcus (17.9%, 10/56). The susceptibility rates of Streptococcus to penicillin, cefatriaxone, vancomycin and levofloxacin were 66.0%, 57.1%, 94.1% and 92.4%, respectively. Patients received PPV+IVI and IVI as initial treatment were 49 eyes (87.5%, 49/56) and 7 eyes (12.5%, 7/56), respectively. Vitreous injection of glucocorticoids were performed in 17 eyes (30.4%, 17/56); and systemic antibiotics were applied in 52 cases (92.9%, 52/56). At the final follow-up, 47 eyes were recorded with visual acuity. Twenty (35.7%, 20/56) had best corrected visual acuity (BCVA)≥0.05 and 27 (48.2%, 27/56) had BCVA <0.05, of which 1 (1.8%, 1/56) had an eyeball enucleation. The etiology of endophthalmitis, streptococcal species, initial treatment with PPV, vitreous injection of glucocorticoids, and systemic antibiotics did not significantly affect patients' visual outcomes ( P>0.05). Timely visit to the hospital after the onset of symptoms (≤3 days) was significantly associated with achieving a final BCVA above 0.05 ( P=0.025). Conclusions:Ocular trauma was the primary cause of streptococcal endophthalmitis. Streptococcus viridans is the most common pathogenic bacterium. Streptococci had high susceptibility to vancomycin, but patients' visual outcomes were poor.

Purpose: To evaluate the clinical characteristics and visual acuity outcomes of patients who presented with endophthalmitis prior to and during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This multicenter retrospective case series with historical controls included consecutive patients presenting with any form of endophthalmitis from March 1, 2019 to September 1, 2019 (pre-COVID-19) and from March 1, 2020 to September 1, 2020 (COVID-19) at Mayo Clinic Rochester (MCR), Health System (MCHS), Arizona (MCA), and Florida (MCF) sites. Cases were divided into "pre-COVID-19" versus "COVID-19" groups depending on when they first presented with endophthalmitis. Results: Twenty-eight cases of endophthalmitis presented to all Mayo Clinic sites during the study period. Of these, 10 patients presented during the first six months of the COVID 19 pandemic. During the same six-month period the year prior, 18 patients presented with endophthalmitis. Endophthalmitis etiology (post-injection, post-cataract extraction, post glaucoma filtering surgery, post-pars plana vitrectomy, endogenous, and others) was similar between both groups (P = 0.34), as was post-injection endophthalmitis rate (P = 0.69), days to presentation (P = 0.07), initial management (P = 0.11), culture-positivity rate (P = 0.70), and need for subsequent pars plana vitrectomy (P = 1). Visual acuity outcomes were similar between both groups at six months, however, the mean LogMAR visual acuity at presentation was worse in the COVID-19 group compared to the pre-COVID-19 group (2.44 vs 1.82; P = 0.026). Conclusion: Clinical characteristics and the post-injection endophthalmitis rate were similar during both periods, however, patients presented with worse vision during the pandemic suggesting that the pandemic may have contributed to delayed presentation, regardless, outcomes are still poor

Despite the introduction of novel sutureless posterior chamber intraocular lens (IOL) fixation techniques, some conditions still require suture-assisted scleral fixation. If the scleral fixation suture knot is left directly under the conjunctiva, it may become exposed, resulting in an increased risk of endophthalmitis. To avoid this problem, we offer a new alternative, simple, and safe way for burying the end of the suture using knots in this report.

ABSTRACT Purpose: The study aimed to assess the anatomical and functional success rates of penetrating keratoplasty with temporary keratoprosthesis-assisted vitreoretinal surgery. Methods: This retrospective study included 15 eyes of 14 patients, recording demographic characteristics, pre-operative anterior and posterior segment pathologies, intraoperative complications, postoperative graft status, retinal attachment, and complications and evaluating anatomical and functional success rates. Results: The mean follow-up period was 29.8 ± 19.1(6-60) months. The most common pre-operative corneal pathology was graft abscess (7 eyes [46.7%]), and the most common diagnosis of the posterior segment was endophthalmitis (7 eyes [46.7%]). Five (33.3%) cases had visual acuity between 0.001-0.08. Pre-operative endophthalmitis was diagnosed in all five cases with anatomical failure.Conclusion: Temporary keratoprosthesis-assisted vitreoretinal surgery with penetrating keratoplasty is an effective method to treat acute/subacute pathologies of the concomitant anterior and posterior segment. However, results may vary on a case-by-case basis. Pre-operative endophthalmitis is a poor prognostic factor for long-term success.
RESUMO Objetivo: Avaliar as taxas de sucesso anatômico e funcional da ceratoplastia penetrante associada à cirurgia vitreorretiniana assistida por ceratoprótese temporária. Métodos: Foram incluídos neste estudo retrospectivo 15 olhos de 14 pacientes. Registraram-se as características demográficas, as patologias pré-operatórias dos segmentos anteriores e posteriores, as complicações perioperatórias, a condição pós-operatória do implante e a fixação e as complicações da retina. Foram avaliadas as taxas de sucesso anatômico e funcional. Resultados: O período médio de acompanhamento foi de 29,8 ± 19,1(6-60) meses. A patologia corneana pós-operatória mais comum foi o abscesso do implante (7 olhos, 46,7%) e o diagnóstico mais comum no segmento posterior foi a endoftalmite (7 olhos, 46,7%). Cinco casos (33,3%) mostraram acuidade visual entre 0,001 e 0,08. Foi diagnosticada endoftalmite pré-operatória em todos os 5 casos com insucesso anatômico. Conclusão: A cirurgia vitreorretiniana assistida por ceratoprótese temporária associada à ceratoplastia penetrante é um método eficaz de tratamento de patologias agudas e subagudas concomitantes nos segmentos anterior e posterior. Porém, os resultados podem variar de caso a caso. A endoftalmite pré-operatória é um fator de pior prognóstico de sucesso de longo prazo.

Purpose: To assess the fluoroquinolone resistance pattern and trends among bacterial isolates from ocular infections over a 16?year period and explore alternative antibiotics in fluoroquinolone?resistant strains. Methods: In this retrospective, longitudinal study, the microbiology laboratory records of patients with different ocular infections diagnosed at an eye institute in central India from 2005–2020 were reviewed to determine the pattern of fluoroquinolone (ciprofloxacin, ofloxacin, gatifloxacin, and moxifloxacin) resistance. Antibiotic susceptibility testing was done using the Kirby–Bauer disc diffusion method. Results: In 725 Gram?positive bacteria, the resistance of ciprofloxacin, ofloxacin, gatifloxacin, and moxifloxacin was 55.9% (95% confidence interval [CI]: 52.2 – 59.6), 42.7% (95% CI: 39.0 – 46.4), 47.6% (95% CI: 43.9 – 51.3), and 45.6% (95% CI: 41.7–49.5), respectively. In 266 Gram?negative bacteria, the resistance of ciprofloxacin, ofloxacin, gatifloxacin, and moxifloxacin was 57.9% (95% CI: 51.9 – 63.9), 56.0% (95% CI: 49.7 – 62.1), 59.9% (95% CI: 53.8 – 66.0), and 74.3% (95% CI: 68.3 – 80.2), respectively. A declining trend in resistance to ciprofloxacin (P < 0.001), ofloxacin (P < 0.001), and moxifloxacin (P < 0.001) was seen in Gram?positive bacteria, whereas a reduction in resistance to only moxifloxacin (P = 0.04) was seen in Gram?negative bacteria. In fluoroquinolone?resistant Gram?positive bacteria, cefuroxime exhibited the highest susceptibility, whereas in fluoroquinolone?resistant Gram?negative bacteria, colistin exhibited the highest susceptibility. Conclusion: Fluoroquinolone resistance was high among bacteria from ocular infections in central India, but a declining trend in resistance to some of the fluoroquinolones was observed in recent times. Cefuroxime and colistin emerged as alternatives in fluoroquinolone?resistant Gram?positive and Gram?negative bacterial infections, respectively.
摘要
Objetivo: Determinar la incidencia de infecciones relacionadas a la bula de filtración en pacientes sometidos a trabeculectomía; así como su comportamiento clínico. Métodos: Se realizó un estudio descriptivo longitudinal y retrospectivo. El universo estuvo comprendido por 1320 ojos con trabeculectomía y muestra conformada por 7 ojos con diagnóstico de infección relacionada a la bula de filtración operados en el Centro Oftalmológico de Villa Clara desde enero del 2012 hasta diciembre del 2021. Resultados: La incidencia global de infección en la bula de filtración fue de 0,53 por ciento. La incidencia de blebitis y de blebitis-endoftalmitis fue 0,15 por ciento y 0,38 por ciento, respectivamente. Los hombres fueron los más afectados y la edad media fue de 64,7 años. En todos los casos, la infección se presentó de forma tardía con una media de 4,1 años. El 57,1 por ciento tuvo una agudeza visual mejor corregida al inicio de la infección de movimiento de manos. Se reportó crecimiento bacteriano en un 57,1 por ciento, el estafilococo coagulasa negativo fue el germen más frecuente. El control de la infección se logró en 6 pacientes mientras 2/3 de ellos no tuvo mejoría de la agudeza visual mejor corregida a la resolución de la infección, todos con blebitis-endoftalmitis. Conclusiones: Las infecciones relacionadas a la bula de filtración son poco comunes. Se presentan con frecuencia años después de la cirugía filtrante y con mala agudeza visual. Los ojos con blebitis-endoftalmitis tienen una pobre recuperación visual a pesar del tratamiento(AU)
Purpose: To determine the incidence of filtration bullae-related infections in patients undergoing trabeculectomy; as well as their clinical behavior. Methods: A longitudinal and retrospective descriptive study was performed. The universe was comprised of 1320 eyes with trabeculectomy and the sample consisted of 7 eyes with a diagnosis of infection related to the filtration bulla operated at the Villa Clara Ophthalmologic Center between January 2012 and December 2021. Results: The overall incidence of infection in the filtration bullae was 0.53 percent. The incidence of blebitis and blebitis-endophthalmitis was 0.15 percent and 0.38 percent, respectively. Males were the most affected and the average age was 64.7 years. In all cases, the infection presented late with a average age of 4.1 years. Fifty-seven point one percent had best corrected visual acuity at the onset of hand motion infection. Bacterial growth was reported in 57.1 percent, coagulase negative staphylococcus was the most frequent germ. Infection control was achieved in 6 patients while 2/3 of them had no improvement of best corrected visual acuity at resolution of infection, all with blebitis-endophthalmitis. Conclusions: Infections related to filtration bullae are uncommon. They occur frequently years after filtering surgery and with poor visual acuity. Eyes with blebitis-endophthalmitis have poor visual recovery despite treatment(AU)

Abstract Objective: Acknowledging the rates of endophthalmitis after cataract surgery is very important to understand the seriousness of the disease. Until now, there is no data of this situation in Argentina. The aim of this study was to estimate the incidence of postoperative endophthalmitis after cataract surgery at a tertiary hospital, a medical facility which provides a high degree of subspecialty expertise, in Buenos Aires, Argentina. Method: Retrospective cohort study of adult patients who underwent cataract phacoemulsification sur gery between 2006 and 2020 at Hospital Italiano de Buenos Aires, was performed. Patients with endophthalmitis diagnosis within the first 6 weeks after surgery were included. Those who underwent extracapsular surgery or combined surgeries were excluded. Results: A total of 29 326 cataract surgeries were performed in ten years. The annual incidence of acute postoperative endophthalmitis after cataract surgery was 0.102% (95% CI 0.069-0.146). Thirty cases of endophthalmitis were diagnosed. The main microorganism was Pseudomonas aeruginosa (45.4%). Final visual acuity was higher than 0.3 (LogMAR) in 46.6% of the patients. Conclusion: The incidence of endophthalmitis after cataract surgery in this hospital is within the range reported globally. Knowing the regional incidence contributes to decide if new prophylaxis measures are necessary.
Resumen Objetivo: Conocer las tasas de endoftalmitis después de la cirugía de cataratas es muy importante para comprender la gravedad de la enfermedad. Hasta el momento, no hay datos de su situación en Argentina. El objetivo de este estudio fue estimar la incidencia de endoftalmitis postoperatoria tras cirugía de catarata en un hospital de tercer nivel o alta complejidad de Buenos Aires, Argentina. Método: Se realizó un estudio de cohorte retrospectivo de pacientes adultos operados de facoemulsificación de cataratas entre 2006 y 2020 en el Hospital Italiano de Buenos Aires. Se incluyeron pacientes con diagnóstico de endoftalmitis dentro de las prime ras 6 semanas posteriores a la cirugía. Se excluyeron los pacientes que se sometieron a cirugía extracapsular o cirugías combinadas. Resultados: En diez años se realizaron un total de 29.326 operaciones de cataratas. La incidencia anual de endoftalmitis postoperatoria aguda después de la cirugía de cataratas fue del 0.102% (IC del 95%: 0.069-0.146). Treinta casos de endoftalmitis fueron identificados. El principal microorganismo fue Pseudomonas aeruginosa (45.4%). La agudeza visual final fue superior a 0.3 (LogMAR) en el 46.6% de los pacientes. Conclusión: La incidencia de endoftalmitis después de la cirugía de cataratas en este hospital está dentro del rango reportado a nivel mundial. Conocer la incidencia regional contribuye a decidir si son necesarias nuevas medidas de profilaxis.
