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

Abstract
Citrobacter koseri is a bacillus that causes infrequent endophthalmitis. 6% of cultures in endophthalmitis are Gram -, and as in these, C. koseri is associated with a poor visual prognosis. We present a 65-year-old man who works in an animal laboratory. He went to emergencies with loss of vision in his left eye due to a vitreous hemorrhage. A vitrectomy was performed and 3 days later, endophthalmitis was diagnosed. Vancomycin and Ceftazidime were applied in eye drops and in two intravitreal injections. 24 h later he returned with a lens extrusion. Due to the severity of the condition, an evisceration was performed. Subsequently, the samples confirm the microorganism. We assume that the entry point for the bacterium was the sclerotomies through the exposed suture material, after handling rodent feces.

Int J Retina Vitreous 2023; 9:58. [PMID: 37752604 PMCID: PMC10521422 DOI: 10.1186/s40942-023-00490-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 08/14/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND To describe the incidence of endophthalmitis and the treatment outcomes of acute bacterial endophthalmitis following intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections in a Brazilian hospital. The analysis was based on the timing of infection after intravitreal injection, culture results, visual acuity, and the presence of epiretinal membrane after a 1-year follow-up period, spanning nine years. METHODS This retrospective case series, conducted over a 9-year period, aimed to evaluate the treatment outcomes of acute endophthalmitis following intravitreal Bevacizumab injections. The inclusion criteria involved a chart review of 25 patients who presented clinical signs of acute endophthalmitis out of a total of 12,441 injections administered between January 2011 and December 2019. Negative culture results of vitreous samples or incomplete data were excluded. Ultimately, 23 patients were enrolled in the study. Eight patients were treated with intravitreal antibiotic injections (IVAI) using vancomycin 1.0 mg/0.05mL and ceftazidime 2.25 mg/0.05mL, while 15 patients underwent pars plana vitrectomy (PPV) followed by intravitreal antibiotic injections at the end of surgery (IVAIES). The main outcome measures were the efficacy of controlling the infection with IVAI as a standalone therapy compared to early PPV followed by IVAIES. Data collected included pre-infection and one-year post-treatment best corrected visual acuity (BCVA), optical coherence tomography (OCT) abnormalities, and enucleation/evisceration rates. To compare groups, Mann-Whitney and ANOVA tests were employed for statistical analysis. RESULTS The incidence rate of bacterial endophthalmitis was 0.185% (1/541 anti-VEGF injections), with the highest infection rates observed in 2014 and 2017. Patients presented clinical symptoms between 2 and 7 days after injection. The most common isolated organisms were coagulase-negative Staphylococci and Streptococci spp. Treatment outcomes showed that both IVAI and PPV + IVAIES effectively controlled the infection and prevented globe atrophy. After one year, the PPV group with BCVA better than Light Perception had a significantly better BCVA compared to the IVAI group (p 0.003). However, PPV group had higher incidence of epiretinal membranes formation compared to the IVAI group. (P 0.035) CONCLUSION: Anti-VEGF injections carry a risk of developing acute bacterial endophthalmitis. Isolated antibiotic therapy could be an effective treatment to control the infection, but performing PPV + IVAIES as a primary treatment showed promising results in terms of improving BCVA after one year, despite a higher rate of epiretinal membrane formation. Further studies are needed to confirm these findings.

Abstract
BACKGROUND Culture negative (CN) but presumed infectious endophthalmitis poses a huge diagnostic challenge in terms of clinical management. This article outlines the current state of knowledge of infectious endophthalmitis with negative cultures and summarizes the recommendations for the work up of this condition along with providing a simple algorithm, by putting into context the recent concerns about over-diagnosing endophthalmitis. METHODS We searched the PubMed and Scopus databases for large hospital based studies on diagnosis of endophthalmitis, with emphasis on culture-negative infections in October 2021. Only clinical studies written in English were included. Basic science studies, letters to the editor and case reports on endophthalmitis were excluded. RESULTS Twenty studies were included in this study. The prevalence of CN endophthalmitis ranged from 40% to 70%. Recent advances in PCR along with high throughput sequencing have helped identify the etiological agent in most cases but these technologies are not easily available, requires advanced bioinformatic analysis and are not cost effective. Role of other inflammatory and relatively low-cost biomarkers in diagnosing a presumed infection is yet to be validated clinically but hold promise in helping ophthalmologists identify the causative agent. CONCLUSIONS CN endophthalmitis is a relatively frequent finding and should not be labelled as sterile endophthalmitis. Recent advances provide a new perspective for ophthalmologist in diagnosis of presumed infectious endophthalmitis and further studies are needed to confirm their utility in clinical settings.

Abstract
The authors report a singular case of post-operative exogenous fungal endophthalmitis caused by a non-pathogenic fungal agent: Aspergillus oryzae. A 75-year-old Caucasian woman with post-penetrating keratoplasty fungal endophthalmitis due to a nonpathogenic A. oryzae, resistant to the current azoles anti-fungal agents, was treated with subtotal vitrectomy, intravitreal injection, and systemic voriconazole therapy. Complete resolution of the endophthalmitis occurred after two subsequent intravitreal injections and a 2-month-long systemic delivery of voriconazole. The quick identification of the fungal agent allowed immediate and targeted therapy. In the article, the safety and efficacy of both systemic and intravitreal voriconazole treatments are discussed.

Abstract
Purpose To describe the etiology and spectrum of isolated pathogens in endophthalmitis over 10 years from an ophthalmic hospital in North China and report their antimicrobial susceptibilities. Patients and Methods The data covered the patients with endophthalmitis treated at Qingdao Eye Hospital from January 2011 to December 2020. Patients’ medical history, pathogenic factors, bacterial and fungal culture results of intraocular specimens, and in vitro drug sensitivity test results were assessed. Results A total of 524 cases were counted in this study. Exogenous endophthalmitis was the main component, accounting for 94.66%, of which 49.62% of eyes had a history of ophthalmic trauma, intraocular surgery in 26.72% and suppurative keratitis in 17.37%. By comparison, endogenous endophthalmitis was found in only 5.34% of eyes. Among the 292 strains of pathogenic organisms obtained by co-culture, gram-positive bacteria accounted for 64.04%, with Staphylococcus epidermidis as the predominant pathogen (29.45%). Gram-positive cocci were identified in 76.77% of eyes with traumatic endophthalmitis, while 53.70% of keratitis-associated endophthalmitis was caused by fungi. The high susceptibility of bacteria to vancomycin (77.78%~98.33%) supported its continued use as empirical treatment. Among the fluoroquinolones, gram-positive cocci showed a higher susceptibility to gatifloxacin (94.83%), while there was a significant decrease to levofloxacin (51.67%). Gram-negative bacteria were less sensitive to cephalosporins (45.95%~66.67%) than fluoroquinolones (68.42%~78.05%) and aminoglycosides (75.00%~78.05%). Fungal susceptibilities to voriconazole and amphotericin B were 90.16% and 70.31% respectively. More than half of the 11 antibiotics were observed to exhibit a trend of reduced susceptibility. Conclusion Ophthalmic trauma was the primary pathogenic factor of endophthalmitis. Gram-positive cocci were the most common pathogens of traumatic and postoperative endophthalmitis, while suppurative keratitis-associated endophthalmitis often resulted from fungal pathogens. Levofloxacin as the preferred antibiotic in the perioperative period and cephalosporin as the first-line drug for the treatment of empiric endophthalmitis need to be vigilant.

Abstract
Endophthalmitis is a severe form of ocular inflammation. The source of pathogens in endogenous endophthalmitis is located inside the body, and infection spreads hematogenously. Although rare, endogenous endophthalmitis is a very serious condition, as this type of inflammation is very devastating for ocular tissues. Prognosis is very poor, and the patients are often in a serious general condition, so they require special care and an individual approach in the treatment process. Thanks to the knowledge of the risks associated with infections of individual tissues and organs as well as potential pathogens and the clinical picture, it is possible to make a correct diagnosis faster and implement the correct treatment. In the case of endogenous endophthalmitis, reaction time is absolutely crucial for prognosis. In this review, we focus primarily on the importance of the primary source of infection for the course of the disease and prognosis.

Abstract
PURPOSE OF REVIEW Acute bilateral blindness has an extensive differential diagnosis that requires a careful history and physical examination to narrow down. In this article, we discuss the pathophysiology and radiographic findings of each possible diagnosis for acute bilateral blindness. RECENT FINDINGS Visual pathology with respect to bilateral blindness can be broadly broken down into 3 anatomic categories: media (i.e., the anterior and posterior chamber of the eye), retina, and neural visual pathway. Possible causes of rapid onset bilateral blindness include bilateral occipital infarcts, endogenous bacterial endophthalmitis, orbital cellulitis, orbital compartment syndrome, cavernous sinus thrombophlebitis, thyroid disease, and bilateral nonarteritic ischemic optic neuropathy. SUMMARY In this case, we present a patient with acute onset of bilateral blindness, in addition to bilateral ophthalmoplegia, proptosis, and orbital chemosis. We believe that this rare case of acute bilateral blindness is thought provoking and aids in the understanding of the differential diagnosis and underlying pathophysiology of visual loss.

Abstract
Endogenous Endophthalmitis (EE) is a rare cause of blindness in the pediatric age group and this may account for the paucity of management guidelines in the literature. In this report, we describe our experience with a 10-year-old immunocompetent female who developed EE and became blind because of rapidly progressive and destructive inflammatory changes in her eye in spite of seemingly timely treatment.

Abstract
OBJECTIVE To report the clinical features and management outcomes of mixed fungal and bacterial endophthalmitis. METHODS Retrospective, consecutive non-comparative case series. Fifteen eyes of 15 patients were included from January 2009 to December 2019 with culture proven mixed fungal and bacterial endophthalmitis. Demography, clinical presentations, interventions received, and final visual and anatomical outcomes were noted. A favorable anatomic outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit. RESULTS The mean age of patients in this series was 34.2 ± 19.6 years (range: 5-61 years). Male preponderance was found in 14 (93.3%). Eight (53.3%) eyes had open globe injury, 5(33.3%) had postoperative endophthalmitis and one (6.6%) each with endogenous endophthalmitis and post-keratitis. Pars plana vitrectomy was done in eight (53.3%) eyes whereas vitreous tap alone was done in seven (46.7%) eyes. Gram positive cocci (n = 11, 73.3%) were the commonest bacterial isolates (n = 7, 46.6%). Staphylococcus aureus (n = 3, 20%) was the most common bacterial isolate. The commonest fungi were filamentous hyaline fungi (n = 5, 33.3%). An unfavorable visual outcome (VA<20/400) was seen in all the eyes. The mean duration of follow-up was 13 ± 18.3 months. Globe salvage was possible only in five (33.3%) eyes. The bacterial isolates were highly sensitive to all of the tested antibiotics. CONCLUSION Mixed fungal and bacterial endophthalmitis occur commonly in a setting of open-globe trauma. The presence of fungus concurrently leads to a very poor management outcome even if the bacterial isolate sensitivity is good.

Abstract
Background Endophthalmitis is a sight-threatening disease characterized by marked progressive inflammation of the vitreous and/or aqueous humors. Limited information is currently available regarding endophthalmitis in the Philippines. This study aimed to provide long-term summary data on endophthalmitis cases seen at the largest tertiary referral hospital in the Philippines. Methods All endophthalmitis cases diagnosed at the Philippine General Hospital from January 1, 2007 to December 31, 2016 were retrieved and classified by etiology. Data pertaining to history, associated risk factors, isolated microorganisms, management, and final visual outcomes for each patient were reviewed. Results A total of 202 cases diagnosed within the audit period were included in the study. These were classified as post-traumatic (55.94%), endogenous (14.36%), acute post-operative (10.40%), keratitis-induced (6.93%), chronic post-operative (5.44%), bleb-associated (3.96%), and suture-associated (2.97%) endophthalmitis. Males comprised 71.29% of the population, while the largest age group affected was 0–10 years (24.75%). The culture-positive rate was 57.89%. The predominant etiology was Gram-positive bacteria (38.18%), followed by Gram-negative bacteria and mixed pathogens (21.82% each), and fungi (18.18%). The most common organisms were Streptococcus, Staphylococcus, Pseudomonas, Aspergillus, and Candida, accounting for 56.45% of isolates. Pars plana vitrectomy was done for 62.87% of patients, intravitreal and other antibiotic therapy in 23.27%, and primary enucleation/evisceration in 10.89%. The final outcomes and best corrected visual acuities were: anophthalmia 11.86%, no light perception/no dazzle 27.84%, light perception 8.76%, hand motions 24.23%, counting fingers 5.15%, 3/200 to 20/50 12.89%, and 20/40 to 20/20 9.28%. Conclusions There was a higher proportion of post-traumatic endophthalmitis cases compared to traditional estimates but consistent with studies from China and Thailand. The majority of these cases involved younger children as well as young to middle-aged males engaged in carpentry and construction work, implying a need for increased public health awareness and strengthening of childcare and workplace safety policies. Our microbiologic profile showed a lower proportion of Gram-positive infections and a higher proportion of mixed pathogen infections compared to other studies. There was also a higher proportion of fungi associated with post-operative and keratitis-induced endophthalmitis. The best outcomes were seen in acute post-operative and bleb-associated endophthalmitis, and the worst outcomes in endogenous and keratitis-induced endophthalmitis. Visual outcomes were poorer compared to other Western and Asian countries, with only 21.7% of patients improving from presentation.

Abstract
Purpose: The objective of our project is to use the National Inpatient Sample Database to identify risk factors for endophthalmitis in cases of open-globe injury (OGI). Methods: This is a cross-sectional observational study of 48 627 cases of OGI from the National Inpatient Sample Database. We performed regression analysis using IBM SPSS Statistics 23. Codes from the International Classification of Disease, Ninth Revision were used to identify ocular findings and conditions. Variables with P values less than .05 on univariate analysis were included in the multivariable regression model; Bonferroni correction was applied to these results. Results: Of the 48 627 cases of OGI, 37 440 (77.0%) occurred in the adult group (21 years and older). Overall, 1018 (2.1%) cases developed posttraumatic endophthalmitis, with 74.5% cases in the adult group. Endophthalmitis developed in 293 (4.5%) eyes with an intraocular foreign body (IOFB). Results of binary logistic regression showed the clinical findings of traumatic cataracts, hypopyon, vitreous inflammation, corneal ulcers, or IOFBs were associated with an increased risk of developing endophthalmitis after OGI. Conversely, orbital fractures, rupture-type injuries, and intraocular tissue prolapse were associated with a decreased likelihood of being diagnosed with endophthalmitis. Conclusions: Endophthalmitis developed in 2.4% of pediatric OGIs and 2.0% of adult OGIs. Traumatic cataract, hypopyon, vitreous inflammation, corneal ulcer, keratitis, retinal detachment, IOFB, and diabetes increased the risk of post-open-globe endophthalmitis.

Abstract
Primary care physicians are at the forefront of patient care and often are the first clinicians to triage and diagnose any eye-related complaints. They must be able to quickly identify vision-threatening pathologies, as delay in treatment of an ocular emergency can result in permanent vision loss. This concise review describes the definition, presentation, examination, and management of various ophthalmic emergencies including blunt ocular trauma, chemical ocular injury, orbital cellulitis, endophthalmitis, acute angle closure glaucoma, optic neuritis, giant cell arteritis, central retinal artery occlusion, retinal detachment, and homonymous hemianopia in a succinct manner.

Abstract
Purpose To analyze the pathogen spectrum of isolated pathogens and antibiotic susceptibility trends of infectious endophthalmitis over 9 years from a large referral eye center in southern China. Methods Data from all inpatients who were clinically diagnosed with infectious endophthalmitis and underwent microbiological evaluation at the Zhongshan Ophthalmic Center from January 2010 to December 2018 were collected retrospectively and analyzed according to different clinical etiologies. Results A total of 816 cases were collected in the study. Open-globe injuries had caused 473 (57.97%) cases, 70 (8.58%) cases presented endophthalmitis after infectious keratitis, 156 (19.12%) cases were postoperative, and endogenous causes accounted for 117 (14.34%) cases. Among the 309 culture-positive cases, the predominant pathogen for both postoperative and posttraumatic endophthalmitis was gram-positive cocci (59.52% and 49.72%, respectively). Regarding keratitis-related endophthalmitis, the main pathogens were filamentous fungi (57.58%) and gram-negative bacilli (30.30%). The pathogens of endogenous endophthalmitis were almost evenly distributed among gram-positive cocci, gram-negative bacilli, and fungi. Eighty-five (10.42%) cases underwent evisceration/enucleation, including 42 cases secondary to keratitis-related endophthalmitis. The incidence of evisceration/enucleation was much higher in keratitis-related endophthalmitis than the total endophthalmitis population (χ2 =123.61, P<0.001). Overall bacteria showed high susceptibility to fluoroquinolones (75.36–100.00%). Gram-positive cocci showed much higher sensitivity to cephalosporins compared to gram-negative bacilli (85.11–92.59% vs 25.42–35.72%). For the five first-line antibiotics analyzed for time trend of susceptibility, four exhibited a significant decrease of susceptibility from 2010–2014 to 2015–2018. Conclusion Between 2010 and 2018, posttraumatic endophthalmitis was the most common form of the treated endophthalmitis in Zhongshan Ophthalmic Center. The causative pathogens varied according to different clinical settings. Even though the overall antibiotic susceptibilities were fairly high, we observed a substantial decrease of susceptibility for most first-line antibiotics.

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

Abstract
Endophthalmitis is an inflammation of both the anterior and posterior chamber. It is diagnosed clinically and involvement of retina and choroid has been documented. (1) Endophthalmitis is classified into infectious and no-infectious categories. Furthermore, the infectious categoery is classified into endogenous and exogenous (Postoperative, Posttraumatic, Bleb associated) which can be caused by either bacterial or fungal infection. Blurry of vision and pain are main symptoms and coagulase negative organisms (gram positive) are main causative of exogenous endophthalmitis. (2) We report a rare case of delayed-onset postoperative endophthalmitis secondary to a rare causative pathogen.

Abstract
Cefuroxime is one of the widely used antibiotics. The objective of this study was to determine pharmacokinetics and disposition in various ocular tissues following topical (TOP), intracameral (IC) and intravitreal (IVT) administration of cefuroxime to rabbits.Following TOP, IC and IVT dosing plasma and various ocular tissues (aqueous humor (AH), vitreous humor (VH), conjunctiva, trabecular mesh (TM), lens and retina-choroid (RC)) were collected and analyzed to understand the disposition of cefuroxime. Postintravenous administration plasma samples were collected to determine the systemic pharmacokinetics.Post-TOP dosing cefuroxime concentrations were observed only in conjunctiva up to 48 h. IC administration showed cefuroxime concentrations in AH up to 8 h; in conjunctiva, TM and plasma, the concentration lasted up to 4 h and in RC and VH till 1 h. IVT administration of cefuroxime showed concentrations in all ocular tissues (up to 8 h) and lasted up to 48 h except in conjunctiva and RC.There was evidence that the mechanism(s) of cefuroxime entry into the eye by via IVT, IC and TOP routes is clearly different. The present ocular tissue data may aid clinicians for considering appropriate choice in the treatment of post-operative ocular complications due to bacterial infections including endophthalmitis.

JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2018; 23:98. [PMID: 30595706 PMCID: PMC6283000 DOI: 10.4103/jrms.jrms_384_18] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Revised: 06/13/2018] [Accepted: 08/03/2018] [Indexed: 01/03/2023]
Abstract
BACKGROUND Although posttraumatic endophthalmitis is an uncommon condition, it causes severe complications, so medical and pharmacological interventions for prevention of endophthalmitis after trauma are a major concern. The aim of this study was to evaluate the efficacy and clinical outcome of oral ciprofloxacin versus intravenous cefazolin/gentamicin for the prevention of endophthalmitis after penetrating ocular trauma. MATERIALS AND METHODS This was a retrospective, descriptive single-center study, including all cases of penetrating ocular trauma seen in the Feiz Hospital, a Tertiary Referral Eye Hospital in Isfahan, Iran, between 2011 and 2017. Data systemically recorded for each patient included clinical, ophthalmological, and demographic findings by a trained medical record abstractor or ophthalmologist reviewing patient records. RESULTS Six hundred and forty-five patients in cefazolin/gentamicin and 273 patients in oral ciprofloxacin groups were included in the study. Our study showed that the incidence of endophthalmitis was not significantly different between the two groups (P = 0.463). In patients with either sharp or blunt penetrating ocular trauma. CONCLUSION Oral ciprofloxacin as a prophylactic treatment could prevent posttraumatic endophthalmitis as effective as injectable cefazolin/gentamicin. Due to easier consumption of oral ciprofloxacin and lower systemic complications, in all patients with penetrating eye trauma, oral administration of ciprofloxacin is preferable to intravenous or intramuscular types of antibiotics to reduce the risk of posttraumatic endophthalmitis.

Abstract
PURPOSE: Intravitreal injection of medication is a rapid rising surgical intervention in modern ophthalmological care. With increasing numbers, the caseload of complications follows and the burden on daily clinical organization increases. This study focuses on developing a standardized treatment protocol to improve care and reduce hazard. METHODS: A standardized treatment protocol was designed and educated to the involved medical doctor and registered nurse. An independent observer used this protocol to evaluate the actions performed during the intravitreal injection. Data on the included patients and products injected were collected. RESULTS: In total, 180 injections of 134 patients were observed between 1 December 2011 and 18 October 2012, divided over 16 measurements. From the fifth measurement on, a 100% protocol adherence for the time out procedure was achieved and maintained over time, with a transient insignificant decrease. The performance of actions of the medical doctor and assisting registered nurse followed the same trend with a rapid increase and 100% protocol adherence. No microorganism caused development of endophthalmitis was recorded. CONCLUSION: The optimization of an intravitreal injection care pathway leads to a more standardized intervention process with no apparent reduction in clinical efficiency and safety.

Abstract
OBJECTIVE To report the incidence of endophthalmitis after the use of intravitreal injection for anti-vascular endothelial growth factor therapy. METHODS This was a single-centre retrospective study conducted at the Aga Khan University Hospital, Pakistan. A total of 11 128 injections were administered to 2054 patients between January 2013 and December 2015. All procedures were performed in an operating room setting, and postinjection antibiotics were prescribed. RESULTS Three cases of endophthalmitis occurred during the study period, with the per-injection risk of endophthalmitis being 0.027%. CONCLUSION The results highlight the benefit of administering intravitreal injections in a surgical setting in addition to enforcing quality protocols. We also recommend further investigation to scrutinize the role of antibiotics prescribed after deploying intravitreal injections so that unnecessary use of such may be curtailed.

Abstract
Purpose. To report a new technique for anterior placement of tubes for glaucoma drainage devices to reduce the risk of tube erosions. Methods. Retrospective review of select cases of Ahmed Valve surgery combined with the novel method of a limbal-based scleral flap covered by a scleral patch graft to cover the tube at the entrance through the limbus. Intraoperative and postoperative illustrations are shown to highlight the method of tube placement. Results. In this retrospective case series, 3 patients are presented illustrating the technique. Two had neovascular glaucoma and one had primary open-angle glaucoma (POAG). On average, intraocular pressure was reduced from 39 ± 14 mmHg to 15 ± 2 mmHg and the number of glaucoma medications was reduced from 4 ± 1 to 0. Preoperative and most recent visual acuities were hand-motion (HM) and HM, 20/60 and 20/50, and 20/70 and 20/30, respectively. Conclusion. The combination of a limbal-based scleral flap with scleral patch graft to cover the tube with glaucoma drainage devices may be an effective means to reduce erosion and protect against endophthalmitis.

Abstract
PURPOSE To report clinical and microbiological profile of patients with ocular candidiasis. MATERIALS AND METHODS Patients with ocular candidiasis were retrospectively identified from microbiology records. Significant isolates of Candida species were identified by Vitek 2 compact system. Minimum inhibitory concentration (MIC) of antifungal agents such as amphotericin B, itraconazole, voriconazole, fluconazole and caspofungin was determined by E test and of natamycin by microbroth dilution assay. Data on treatment and outcome were collected from medical records. RESULTS A total of 42 isolates of Candida were isolated from patients with keratitis-29, endophthalmitis-12 and orbital cellulitis-1. The most common species isolated was Candida albicans (12-keratitis, 4-endophthalmitis, 1-orbital cellulitis). All except one isolate were susceptible to amphotericin B. MIC of caspofungin was in the susceptible range in 28 (96.5%) corneal isolates while 12 out of 29 (41.3%) corneal isolates were sensitive to fluconazole. Resistance to voriconazole was seen in four corneal isolates. All isolates were susceptible to natamycin and all except two isolates were resistant or susceptible dose-dependent to itraconazole. Outcome of healed ulcer was achieved in 12/18 (66.6%) patients treated medically, while surgical intervention was required in 11 patients. Among the isolates from endophthalmitis patients, 11/12 were susceptible to amphotericin B, 6/12 to voriconazole and all to natamycin. Ten out of 11 patients (one patient required evisceration) with endophthalmitis were given intravitreal amphotericin B injection with variable outcome. CONCLUSIONS Ocular candidiasis needs early and specific treatment for optimal results. Candida species continue to be susceptible to most commonly available antifungals including amphotericin B, voriconazole and natamycin.

Abstract
PURPOSE To review the microbiological spectrum and antibiotic sensitivities of the pathogens that cause culture-proven endophthalmitis and to understand the status and trends of antibiotic susceptibility at a public hospital over a 10-year period. METHODS The data of 577 culture-proven endophthalmitis isolates collected between April 2004 and April 2014 were reviewed retrospectively. The antibiotic sensitivities were determined according to the criteria of the Clinical and Laboratory Standards Institute. The changes in antibiotic susceptibility over the 10 years were subjected to χ2 tests for trends. RESULTS Among these isolates, 65% were gram-positive organisms (375), 16.6% were gram-negative organisms (96), and 18.4% were fungi (106). The predominant pathogens were Staphylococcal species (Staphylococcus epidermidis in 175, other coagulase-negative Staphylococci in 41, and Staphylococcus aureus in 54 cases), followed by Bacillus cereus isolates. The Aspergillus species was the most frequently isolated fungus, and Pseudomonas aeruginosa was the most frequently isolated gram-negative bacteria. The antibiotic susceptibilities of gram-positive bacteria were as follows: vancomycin, 97.6%; levofloxacin, 85.1%; gentamicin, 78.7%; rifampin, 77.2%; ofloxacin, 77.2%; chloramphenicol, 76.4%; and ciprofloxacin, 73.7%. The antibiotic susceptibilities of gram-negative isolates were as follows: ceftazidime, 50.5%; ciprofloxacin, 82.2%; amikacin, 81.3%; tobramycin, 80.2%; imipenem, 79.7%; and gentamicin, 78%. Over the 10-year study, there were significant changes in the antibiotic susceptibilities to the following five antibiotics: vancomycin, imipenem, penicillin G, amikacin, and trimethoprim-sulfamethoxazole (TMP-SMX). CONCLUSIONS Vancomycin remains the most appropriate empirical antibiotic for gram-positive bacteria. The susceptibilities of the gram-negative organisms to ciprofloxacin and amikacin were greater than that to ceftazidime. Trends toward increases in the susceptibilities to the following five antibiotics were observed: vancomycin, imipenem, penicillin G, amikacin, and TMP-SMX.

Abstract
Pain involving the eye has numerous etiologies and is a feared challenge of many clinicians. Between a fear of the patient losing vision and a lack of familiarity with the ophthalmic equipment necessary to diagnose the problem, working up eye pain can be a daunting task. While the ophthalmologist can be indispensable in challenging cases of eye pain, this article will help clarify the unique clinical features of each etiology that can help clinicians narrow down the differential and arrive at a diagnosis.

Outcome and Prognostic Factors for Traumatic Endophthalmitis over a 5-Year Period. J Ophthalmol 2014; 2014:747015. [PMID: 25302113 PMCID: PMC4181772 DOI: 10.1155/2014/747015] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2014] [Accepted: 08/11/2014] [Indexed: 11/17/2022] Open
Abstract
Purpose. To evaluate the outcome and identify the prognostic factors of traumatic endophthalmitis over a 5-year period. Methods. We reviewed the medical records of all the traumatic endophthalmities that we treated in our department over the last 5 years (2009–2013). We extracted the following parameters: age, gender, wound anatomy, associated ocular lesions, treatment, and initial and final visual acuities. We used the program SPSS version 20.0.0. for the statistical analysis of our data. Results. During the last 5 years, we treated 14 traumatic endophthalmities, representing 46.66% of all types of endophthalmities. The infection rate in open globe injuries was 8.13% and 34.78%, if an intraocular foreign body (IOFB) was associated. All the patients were males with the median age of 37 years. Initial visual acuities varied between light perception and 0.4 and the timing of treatment from a few hours to 10 days. We administered antibiotic and anti-inflammatory drugs, systemically and intravitreally, in all cases. We performed pars plana vitrectomy in 64.28% of cases. In 57.14% of cases, the final visual acuity was 0.1 or more. Conclusions. IOFBs increased significantly the risk for endophthalmitis. The worse prognostic factors were retinal detachment at presentation and delayed treatment. This trial is registered with IRCT2014082918966N1.

Abstract
We present a rare case of endogenous endophthalmitis caused by Citrobacter koseri. A 69-year-old woman with a history of poorly controlled diabetes and a protracted urinary tract infection (UTI) presented with a painful swollen left eye. There was no history of eye surgery or trauma. Imaging revealed an abscess in the right kidney. Although endophthalmitis is very rare in healthy patient, it is more common in the immunocompromised. In this patient, several multiple system illnesses including poorly controlled diabetes appear to have worked synergistically to make endophthalmitis a realistic complication of an otherwise isolated and remote source of infection, in this case pyelonephritis. Endophthalmitis, in the absence of an obvious exogenous cause, should be investigated thoroughly to exclude metastatic microbial spread. In addition, chronic features of UTI in a patient with poorly controlled diabetes or who is otherwise immunosuppressed warrant the exclusion of an underlying renal abscess.

Abstract
PURPOSE We determined the profiles of sphingomyelin, sphingoid base, sphingoid base-1-phosphate, and ceramide, and their quantitative differences between control and glaucomatous trabecular meshwork (TM) derived from human donors. METHODS Control and primary open angle glaucoma (POAG) TM samples were collected from cadaver donors. In addition, POAG TM surgical specimens also were procured. Lipid extraction was performed using suitable modifications of the Bligh and Dyer method. Protein concentrations were determined using Bradford's method. Lipids, identified using standardized class-specific lipid mass spectrometry, were quantified using a two-step ratiometric process. Gomori methenamine silver (GMS) staining was performed for detection of presence of Fusarium in the anterior eye tissue sections. PCR analyses were performed for detection of Fusarium species in the donor TM samples. RESULTS Several species of sphingomyelin, sphingoid base, sphingoid base-1-phosphate, and ceramide were common between control and POAG TM. Only a subset of species in some of these classes were identified uniquely either in controls or in POAG TM. Several lipid species of fungal origin (many from Fungi imperfecti, Fusarium species) were found to be common between control and POAG TM. The GMS staining and PCR analyses showed presence of DNA belonging to Fusarium species suggesting latent commensalism. CONCLUSIONS Most sphingolipids and ceramides (except a few unique to a specific donor TM group) were found to be common in the control and POAG TM. Latent commensalism by Fusarium was suggested by identification of Fusarium-specific lipids, which was supported further by PCR amplification and sequencing of DNA.

Abstract
Endophthalmitis is a potential vision-threatening complication following surgical procedures (postoperative endophthalmitis [POE]), trauma (posttraumatic endophthalmitis [PTE]), and bacteremic seeding of the eye from a distant infection site (endogenous endophthalmitis [EE]). Several studies have revealed the polybacterial characteristics of endophthalmitis, which make the administration of antibiotics to treat the disease challenging. However, until now, the polybacterial communities of POE, PTE, and EE have not been precisely studied. Hence, the present study was designed to identify the bacterial community of endophthalmitis through 16S rRNA gene libraries. Of the 40 intraocular samples tested, 30 libraries were constructed with bacterial nested-PCR-positive samples. The obtained recombinant clones were screened through amplified rRNA gene restriction analysis (ARDRA) to identify unique clones. The multiple types of ARDRA patterns (P=0.345) and diverse bacterial sequences (P=0.277) within the libraries revealed the polybacterial nature of infection in POE, PTE, and EE. Moreover, to the best of our knowledge, this is the first report on polybacterial infection in EE. Gram-positive bacteria, including Bacillus spp. (n=19), Streptococcus spp. (n=18), Staphylococcus spp. (n=6), Exiguobacterium spp. (n=3), Gemella spp. (n=2), Enterococcus spp. (n=2), a Lysinibacillus sp. (n=1), a Clostridium sp. (n=1), and a Nocardia sp. (n=1), and Gram-negative bacteria, including Serratia spp. (n=18), Pseudomonas spp. (n=10), Enterobacter spp. (n=8), Acinetobacter spp. (n=3), Pantoea spp. (n=3), a Haemophilus sp. (n=1), and a Massilia sp. (n=1), were identified. Interestingly, among them, 10 bacterial species were not previously reported to be associated with endophthalmitis or other ocular infections. Besides, the presence of 4 unidentifiable clones suggests the possibility of novel organisms that might cause eye infections. Therefore, it is recommended that, in addition to the polybacterial nature of POE, PTE, and EE infections, the spectrum of the pathogenic bacterial community identified in this work should be considered while administering antibiotic therapy in suspected endophthalmitis cases.

Abstract
A correct diagnosis of uveitis is often challenging, given the wide range of possible underlying conditions and the lack of typical phenotypes. Management decisions may be difficult in view of the risk of visual loss with either inappropriate or delayed therapy. Analysis of the vitreous may therefore be used to provide the clinician with valuable information. In this paper, we describe the main clinical situations in which vitreous sampling is indicated and provide some guidance to clinicians for tailoring their requests. These situations include suspected intraocular infection and suspected intraocular malignancy. We describe the principal tests carried out on vitreous samples, including cultures, polymerase chain reaction-based testing, and cytokine analysis. Limitations of the tests used are likely to become less as more advanced testing methods are introduced. The importance of selecting the appropriate investigations to support a clinical suspicion is emphasised, as is the interpretation of test results within a clinical context.
