Analysis of association of bandage contact lens with serious vision-threatening diseases and their management.

BACKGROUND: Bandage contact lenses are important aids for aftercare following ocular surgery and for a wide variety of ocular surface conditions. However, bandage contact lenses also bear the risk of fostering microbial infections of the cornea. We herein report the safety profile of bandage contact lenses from a comprehensive review of medical records in a tertiary care eye hospital in Germany. METHODS: We identified 638 consecutive patients who had been prescribed at least one bandage lens during the past 10 years. For these, we performed a computerized search for the following adverse events: (1) endophthalmitis, (2) emergency keratoplasty and (3) vision loss of at least 2 lines according to the Early Treatment Diabetic Retinopathy Study (ETDRS). We manually assessed the relatedness of each event to the bandage lens. Events later than 100 days following the bandage lens prescription were not considered to be related to bandage contact lenses. RESULTS: We observed 267 adverse events, with 120 occurring within 100 days after bandage lens prescription. This left a total of 18 endophthalmitis events, 21 penetrating keratoplasties and 81 eyes with vision loss of at least 2 ETDRS lines (for individual review of relatedness). Only two episodes of endophthalmitis could be linked to bandage lens wear. All other adverse events were due to causative conditions that had already been present prior to bandage contact lens insertion. CONCLUSIONS: Severe adverse events after bandage contact lens wear are not uncommon because lenses are used in patients suffering from preexisting ocular conditions. However, severe adverse events were almost never caused by the bandage contact lenses directly in our hands. We therefore conclude that bandage contact lenses are safe given proper ophthalmological supervision.

Clinical features, treatment and prognosis of patients with endogenous infectious endophthalmitis.

PURPOSE: To investigate whether the clinical characteristics, treatment and prognosis of endogenous infectious endophthalmitis (EIE) have changed over the past 5 years. METHODS: Retrospectively analyze all articles about EIE published in the PubMed, Web of Science, and Embase databases from 2017 to 2021. RESULTS: A total of 128 patients and 147 eyes (46 left and 60 right) were included in the study. The mean age at diagnosis was 51 ± 19 years. The most common risk factors were diabetes and intravenous drug use. From 2017 to 2021, Klebsiella was the most common pathogenic microorganism (22%), and vitreous culture had the highest positivity rate. The most common complaint was blurred vision. The mean visual acuity (logMAR) at onset was 2.84, and the clinical symptoms were vitreal inflammation and opacity (63%), ocular pain (37%), and conjunctival congestion (36%). The ocular inflammation could be reduced by intraocular antibiotics or vitrectomy. However, the visual prognosis, with a mean logMAR of 2.73; only 50% of the eyes reached a visual acuity level of finger count and above. Changes in diagnostics over the past 5 years have mainly manifested as more diverse microorganism culture methods. In addition to conventional culture methods, PCR, sputum culture and aqueous humour culture are also commonly used for the diagnosis of pathogenic bacteria, improving the positive culture rate and visual prognosis. CONCLUSION: The prognosis of EIE is poor. It is recommended to pay attention to the pathogenic bacteria culture results and accompanying systemic diseases and to diagnose and treat patients as soon as possible.

Clinical characteristics and management outcome of acute infectious endophthalmitis.

PURPOSE: This study aimed to investigate the demographics, clinical characteristics, and management outcomes of patients with acute infectious endophthalmitis (AIE). METHODS: This retrospective chart review was conducted on all patients admitted with the clinical diagnosis of infectious endophthalmitis from 2017 to 2022. Demographic data, patients' clinical characteristics, the type of acute infectious endophthalmitis (post-operative, post-traumatic, bleb-associated, and endogenous endophthalmitis), the type of surgical procedure in the post-operative cases, the microbiologic analysis results of vitreous samples, therapeutic measures, and visual outcomes of patients were recorded. RESULTS: In this study, 182 participants, including 122 male (67%) and 60 (33%) female, were involved. The mean age of patients was 54.56 ± 21 years, with a range of 1-88 years old. The most prevalent type of AIE was post-operative (59.9%), followed by endogenous (19.2%), post-traumatic (17%), and bleb-associated (3.8%). The most common type of intraocular surgery in the post-operative subgroups of AIE patients was phacoemulsification (57.8%). The median (interquartile range) of the primary and final BCVA of patients was 1.5 (1.35, 1.85) and 0.65 (0.35, 1.35), respectively. Vitreous haziness grade (OR, 2.89; 95% CI, 1.11-5.74; p = 0.009) and the primary VA (OR, 60.34; 95% CI, 2.87-126.8; p = 0.008) revealed statistical significance for final vision loss. CONCLUSION: AIE is a devastating condition with poor visual outcomes, which presents with acute inflammatory signs and symptoms regardless of its type. However, prompt and appropriate treatment leads to visual recovery to a functional level in many patients.

CLINICAL PRESENTATIONS, MICROBIOLOGY, AND FACTORS AFFECTING MANAGEMENT OUTCOMES IN LENS ABSCESS WITH CONCURRENT ENDOPHTHALMITIS.

PURPOSE: To describe the clinical presentations, microbiology, and factors affecting management outcomes in lens abscess with concurrent endophthalmitis. MATERIALS: A retrospective, consecutive, noncomparative series including cases of endophthalmitis with concurrent lens abscess from January 2017 to May 2021. RESULTS: This study included 102 eyes, predominantly male (71.6%). All cases were posttrauma. The mean age noted was 30.47 ± 19.51 years. Presenting vision was logMAR 3.02 ± 0.74 (median 3.5, Snellen 20/63245). A favorable anatomical outcome was seen in 63 eyes (61.8%), while a final favorable functional outcome was seen in 51 eyes (50%). The mean follow-up duration was 10.04 ± 10.87 months (median 4.5). Final vision was logMAR 2.13 ± 1.32 (median 2.7, Snellen 20/10023) (P < 0.0001). The mean follow-up duration was 10.04 ± 10.87 months (median 4.5). Increasing age (OR 1.04, P = 0.02), female sex (OR 7.91, P = 0.007), initial intervention of vitrectomy instead of limited vitreous biopsy (OR 11.72, P = 0.009), and a negative vitreous culture (OR 14.28, P = 0.0004) predicted a favorable anatomical outcome. Absence of a corneal infiltrate (OR 11.11, P = 0.003) and initial intervention of vitrectomy instead of a limited vitreous biopsy (OR 21.96, P < 0.0001) predicted a favorable functional outcome. Culture positivity was seen in 56.9% of the cases. Gram-positive organisms were predominant (n = 41) followed by Gram-negative organisms (n = 12) and fungi (n = 10). CONCLUSION: Lens abscess can present concurrently with traumatic endophthalmitis. Management should involve the complete removal of the crystalline lens along with a pars plana vitrectomy for optimal outcomes.

CLINICAL CHARACTERISTICS AND VISUAL OUTCOMES IN ENDOPHTHALMITIS AFTER KERATOPROSTHESIS IMPLANTATION.

PURPOSE: To describe the presentation, microbiology, management, and prognosis of eyes with endophthalmitis after Boston keratoprosthesis implantation. METHODS: Retrospective case series with history, diagnostics, management, and outcomes data in endophthalmitis after keratoprosthesis implantation presenting to a tertiary center between 2009 and 2020. RESULTS: Of 137 keratoprosthesis-implanted eyes, 7 eyes of 7 patients (5%) developed endophthalmitis. On presentation, 6 (86%) reported decreased visual acuity, and only 1 (14%) reported pain. Peripheral corneal ulcers were present in 2 eyes (29%). Seidel testing was negative in all cases. Six eyes (86%) had retroprosthetic membranes. One (14%) underwent initial pars plana vitrectomy with mechanical vitreous biopsy, whereas 6 (86%) received a needle vitreous tap-half of which were dry. Organisms were isolated after vitreous tap in two eyes: Streptococcus intermedius and Mycobacterium abscessus. The mean visual acuity preendophthalmitis, at presentation, and at 6 months were 20/267, 20/5,944, and 20/734, respectively. The visual acuity improved 9.08 ± 11.78 Early Treatment Diabetic Retinopathy Study lines from presentation to 6 months. Six-month visual acuity was correlated with preendophthalmitis visual acuity (r = 0.92, P = 0.003) but not presenting visual acuity (P = 0.838). CONCLUSION: Visual acuity at 6 months is correlated with preendophthalmitis visual acuity, not presenting visual acuity. Endophthalmitis should be considered in the differential diagnosis of painless intraocular inflammation any time after keratoprosthesis implantation, even if Seidel negative.

Treatment of long-term endophthalmitis developing after intraocular lens implantation in children: a retrospective study.

BACKGROUND: To discussed the risk factor and the management of vitrectomy for long-term endophthalmitis developing after intraocular lens (IOL) implantation in children. METHODS: We retrospectively investigated the clinical characteristics and surgical outcomes of long-term endophthalmitis developing after IOL implantation in children. RESULTS: Four eyes of four children were included in the study. The mean time to endophthalmitis development after IOL implantation was 3.0 ± 0.8 years. The corneal or scleral sutures may have been caused the infection. All 4 patients underwent vitrectomy and received intravitreal antibiotics with or without IOL removal. At the last follow-up, the outcomes were satisfactory; the fundus was clear, the retina remained attached, the visual acuity improved, and there were no severe complications. CONCLUSIONS: The use of scleral sutures and the exposure of conceal sutures may induce the onset of long-term endophthalmitis after IOL implantation. Complete vitrectomy and appropriate use of antibiotics are effective in the treatment of long-term endophthalmitis developing after IOL implantation in children.

Case Report: Microsporidial Endophthalmitis after Penetrating Eye Trauma.

SIGNIFICANCE: In the recent past, there are increasing publications on microsporidia affecting the cornea in Asian population. However, microsporidia-causing endophthalmitis has been rarely reported. This report intends to draw the attention of eye care professionals to consider microsporidia as a differential diagnosis in cases of keratitis or endophthalmitis after ocular trauma. PURPOSE: The purpose of this study was to report a case of microsporidial endophthalmitis after corneal tear in an otherwise healthy patient. CASE REPORT: A 62-year-old healthy gentleman sustained injury to the left eye cornea with the tip of a soiled and wet screw driver. Two days after the corneal tear suturing, he complained of pain. On examination, circumcorneal congestion with hypopyon of 2 mm in height was present. Vitreous tap and intravitreal antibiotics were injected. Vitreous tap showed microsporidia. Pars plana vitrectomy was performed. His vision improved to 6/12. CONCLUSIONS: Microsporidia are an emerging cause of stromal keratitis. In the recent past, there has been an increase in microsporidial keratitis in both immunocompetent and immunocompromised individuals. History of trauma especially in rainy season and exposure to soil are reported risk factors. This is a case report on microsporidia-causing endophthalmitis after corneal tear repair. Ophthalmologists and optometrists should be aware of the possibility of microsporidia as a potential pathogen causing stromal keratitis or endophthalmitis in a setting of ocular trauma. Early treatment can result in good visual recovery.

[Ophthalmopathologic Aspects of Endophthalmitis]. / Endophthalmitis aus ophthalmopathologischer Sicht.

Endophthalmitis is one of the most severe ophthalmic emergencies. Most patients experience a permanent decrease in visual acuity after the event, but the eye can be preserved in most cases. However, when the eye is enucleated after endophthalmitis, ophthalmopathologic investigation of the globe with respect to the clinical history can provide valuable information regarding the ultimately frustrating course of the disease that can be helpful for the treatment of future patients. Often, valuable aspects also emerge with regard to the therapeutic approach. For example, in therapy-resistant fungal endophthalmitis the necessity of penetrating keratoplasty with a large graft diameter and possibly even removal of the lens including the capsular bag should be stressed. In the following, five enucleated eyes with a different spectrum of endophthalmitis, as well as different potential pathways of exogenous and endogenous endophthalmitis, are illustrated clinically and ophthalmopathologically. In summary, endophthalmitis requires urgent intervention; however, various differential diagnoses must be excluded. Histopathologic examination of enucleated eyes is helpful for understanding the course of the disease and may also have forensic significance.

[Chinese expert consensus on the diagnosis and management of infectious endophthalmitis after ophthalmic surgery (2022)].

Infectious endophthalmitis after ophthalmic surgery refers to postoperative endophthalmitis associated with pathogen infection. The incidence of infectious endophthalmitis after ophthalmic surgery has been reduced, but there are still many controversial issues in its diagnosis, treatment and prevention. The Chinese Vitreo-Retina Society of Chinese Medical Association, together with domestic experts in cataract, trauma and glaucoma, has synthesized all the current research evidences available at home and abroad and reached consensus opinions after careful discussion, in order to provide reference for preventing and managing infectious endophthalmitis after ophthalmic surgery safely and effectively, and thus to improve its cure rate and patients' visual function.

FEATURES AND OUTCOMES OF EYES THAT UNDERWENT SURGICAL REPAIR OF RHEGMATOGENOUS RETINAL DETACHMENTS AFTER BEING TREATED FOR ACUTE ENDOPHTHALMITIS.

PURPOSE: To evaluate the etiology, clinical course, and outcomes of eyes that suffered postendophthalmitis rhegmatogenous retinal detachments. METHODS: A retrospective, consecutive case series was conducted of patients managed at Associated Retinal Consultants P.C. from January 2013 to December 2019. Patients were identified as having had endophthalmitis by ICD-9/10 codes. Those with endophthalmitis and/or rhegmatogenous retinal detachment not managed at Associated Retinal Consultants from January were excluded. RESULTS: Charts of 413 patients were reviewed and 19 met inclusion criteria. Incidence of rhegmatogenous retinal detachment following infectious endophthalmitis was 4.6%. The most common inciting events for endophthalmitis was intravitreal injection (9 of 19) and cataract surgery (7 of 19). Fifteen of 19 patients were treated with an injection of intravitreal antibiotics and 4 underwent immediate vitrectomy with antibiotic injection. Biopsy cultures were obtained in 18 of 19 patients and yielded positive growth in 12 (66.7%). Seventeen of the 19 eyes were operable. Final retinal reattachment rate was 88.2% (15 of 17). Mean final logMAR visual acuity was 1.58 (Snellen 20/765). Factors associated with worse final visual acuity after surgical repair included preceding intravitreal injection (P = 0.001), streptococcus species (P = 0.024), presence of proliferative vitreoretinopathy (P = 0.015), and use of silicone oil during primary rhegmatogenous retinal detachment repair (P = 0.010). CONCLUSION: Rhegmatogenous retinal detachments following endophthalmitis occur infrequently. Although most eyes can be repaired surgically, visual outcomes are often poor, particularly in eyes that were infected with streptococcal species and had associated proliferative vitreoretinopathy.

TAP AND INJECT VERSUS PARS PLANA VITRECTOMY FOR POSTPROCEDURAL ENDOPHTHALMITIS: A Meta-analysis.

PURPOSE: To compare the visual outcomes after prompt pars plana vitrectomy (PPV) with tap biopsy and intravitreal antimicrobial injection to treat postinjection and postsurgery endophthalmitis. METHODS: The Cochrane Central Register of Controlled Trials, Ovid MEDLINE, and Ovid Embase databases were searched for articles published between January 2010 and November 2020. Two independent reviewers selected articles and extracted data. We analyzed data in RevMan 5.3 and assessed methodological quality using the Cochrane ROBINS-I tool. The mean improvement in visual outcome was compared between PPV and intravitreal antimicrobial injection as a relative risk of improving ≥2 lines and a mean logarithm of the minimal angle of resolution difference in improvement. RESULTS: Fifteen retrospective case series (1,355 eyes), of which 739 eyes (55%) received intravitreal antimicrobial injection and 616 (45%) received PPV as initial treatment, were included. The overall relative risk of improving 2 or more lines in PPV in comparison with intravitreal antimicrobial injection was 1.04 (95% CI 0.88-1.23; P = 0.61; I2 = 0%) with a mean difference of 0.04 (95% CI -0.18 to 0.27; P = 0.69; I2 = 0%). The results stayed robust when subgroup analysis based on causative procedure for endophthalmitis was performed. CONCLUSION: Intravitreal antimicrobial injection is noninferior to PPV for the treatment of postcataract operation, postinjection, and post-PPV endophthalmitis.

Analysis of retinal detachment resulted from post-operative endophthalmitis treated with 23G pars Plana Vitrectomy.

BACKGROUND: To evaluate the rate, risk factors, functional outcome and prognosis in eyes with retinal detachment after post-operative endophthalmitis treated with 23G Pars Plana Vitrectomy. METHODS: Electronic patient files from 2009 until 2018 were screened for the presence of an endophthalmitis. Included were 116 eyes of 116 patients. This population was evaluated for the rate of retinal detachment after 23G Pars Plana Vitrectomy for endophthalmitis following cataract surgery or intravitreal injection. The main outcome measures were retinal detachment and visual acuity. RESULTS: The reasons for endophthalmitis were previous cataract surgery in 78 patients and following intravitreal injection in 38 patients. The first clinical evidence of endophthalmitis was present in median 5 days after the triggering intervention. Twenty-five eyes (21.55%) developed a retinal detachment an average of 25 days after endophthalmitis. RD is significantly associated with preoperative visual acuity (p = 0.001). CONCLUSIONS: We emphasize the prognostic role of preoperative visual acuity in RD development of the endophthalmitis treated with 23G Pars Plana Vitrectomy.

Treatment outcomes of acute poptoperative infectious endophthalmitis.

BACKGROUND: Acute postoperative endophthalmitis is one of the most severe complications of modern ophthalmic procedures including cataract surgeries, vitrectomy and intravitreal injection (IVI). We evaluated the treatment outcomes of acute postoperative infectious endophthalmitis. METHODS: In this retrospective study, we collected data from 82 patients with acute infectious endophthalmitis within 6 weeks after intraocular surgeries, including cataract surgeries, vitreoretinal surgeries, and IVI, from January 2010 to December 2019. We analyzed the pre-treatment, treatment-related and post-treatment factors that affected visual outcomes. RESULTS: The mean age was 67.65 ± 9.52 years, the proportion of male patients was 56.1%. The mean baseline vision was 1.92 (Snellen Equivalent SE], counting finger [CF]) ± 0.54 logarithm of the minimum angle of resolution (log MAR) and the mean final vision was 0.71 (SE, 39/200) ± 0.80 logMAR. Visual improvement was significant (P < 0.001). The pre-treatment factors affecting final visual outcomes were diabetes, hemodialysis, baseline vision, signs of vitreous opacity, and different surgeries before endophthalmitis; the treatment-related factors affecting visual outcomes were the choice factors between IVI of antibiotics alone and vitrectomy combined with IVI of antibiotics, and the injection numbers of antibiotics; post-treatment factors affecting visual outcomes were complications such as retinal detachment (RD), glaucoma and macular pucker. Furthermore, prior cataract surgery was associated with a better mean final vision of 0.57 (SE, 54/200) ± 0.67 logMAR while prior vitrectomy resulted in the worst mean final vision of 1.38 (SE, 21/500) ± 0.75 logMAR. CONCLUSIONS: The important factors that affected the final visual prognosis, included diabetes, hemodialysis, baseline vision, severity of vitritis, treatment strategies and complications. The treatment outcomes revealed better final vision in prior cataract surgery than vitrectomy.

An 18-Year Overview of Serratia marcescens Ocular Infection.

PURPOSE: Serratia marcescens is a frequent ocular bacterial pathogen implicated in keratitis, endophthalmitis, and conjunctivitis. We evaluated the risk factors and treatment outcomes of ocular infections due to S. marcescens. METHODS: In this retrospective observational study, all S. marcescens-positive cases between February 2002 and February 2020 were reviewed for ocular risk factors that included log of minimal angle of resolution visual acuity (VA), medical management, and time to epithelial defect closure. RESULTS: Fifty-one patients were identified (72.5% females, 46.8±23.3 years). Forty-six patients had complete medical records, and 5 had microbiology data available. The most prevalent ocular risk factors were, contact lens (CL) use (68.6%), corneal disease (52.9%), and history of ocular surgery (41.2%). Mean presenting VA was 1.3±1.0. About half of the patients presented with a central ulcer (49%, 25), large infiltrate (20.4±31.8 mm2 mean), and hypopyon (43.1%, 22). All cases were reported to be susceptible to ciprofloxacin. Defect closure occurred in 52.3±117.1 days and final VA was 0.86±0.88. Adjunctive treatments were required in 14 cases (27.5%). One patient underwent surgical intervention. Features associated with poor VA outcomes included, history of glaucoma (P=0.038), older age at presentation (P<0.001), presence of hypopyon (0.045), poor VA at presentation (0.0086), time to epithelial defect closure (0.0196), and large infiltrate size (P=0.0345). CONCLUSIONS: S. marcescens keratitis and conjunctivitis is associated with CL use and history of ocular surface disease. Worse outcomes were associated with older age, infiltrate size, presence of hypopyon, worse initial VA, longer time to epithelial defect closure, and history of glaucoma.

Endophthalmitis after Cataract Surgery in the United States: A Report from the Intelligent Research in Sight Registry, 2013-2017.

PURPOSE: To determine recent incidence and visual outcomes for acute-onset endophthalmitis after cataract surgery performed in the United States. DESIGN: Retrospective cohort study. PARTICIPANTS: United States cataract surgery patients, 2013-2017 (5 401 686 patients). METHODS: Cases of acute-onset postoperative endophthalmitis occurring within 30 days after cataract surgery were identified using diagnosis codes in the American Academy of Ophthalmology IRIS (Intelligent Research in Sight) Registry database, drawn from electronic health records in ophthalmology practices across the nation. Annual and aggregate 5-year incidences were determined for all cataract surgeries and specifically for standalone procedures versus those combined with other ophthalmic surgeries. Patient characteristics were compared. Mean and median visual acuity was determined at 1 month preoperative as well as 1 week, 1 month, and 3 months postoperative among patients with and without endophthalmitis. MAIN OUTCOME MEASURES: Incidence of acute-onset postoperative endophthalmitis after cataract surgery. RESULTS: A total of 8 542 838 eyes underwent cataract surgery, 3629 of which developed acute-onset endophthalmitis (0.04%; 95% confidence interval, 0.04%-0.04%). Endophthalmitis incidence was highest among patients aged 0 to 17 years (0.37% over 5 years), followed by patients aged 18 to 44 years (0.18% over 5 years; P < 0.0001). Endophthalmitis occurred 4 times more often after combined cases (cataract with other ophthalmic procedures) than after standalone cataract surgeries (0.20% vs. 0.04% of cases), and occurred in 0.35% of patients receiving anterior vitrectomy. Mean 3-month postoperative visual acuity was 20/100 (median, 20/50) among endophthalmitis patients, versus a mean of approximately 20/40 (median, 20/30) among patients without endophthalmitis. However, 4% of endophthalmitis patients still achieved 20/20 or better visual acuity, and 44% achieved 20/40 or better visual acuity at 3 months. CONCLUSIONS: Acute-onset endophthalmitis occurred in 0.04% of 8 542 838 cataract surgeries performed in the United States between 2013 and 2017. Risk factors may include younger age, cataract surgery combined with other ophthalmic surgeries, and anterior vitrectomy. Visual acuity outcomes vary; however, patients can recover excellent vision after surgery. Big data from clinical registries like the IRIS Registry has great potential for evaluating rare conditions such as endophthalmitis, including developing benchmarks, longer-term time trend investigation, and comprehensive analysis of risk factors and prophylaxis.

CLINICAL PRESENTATIONS, DIAGNOSIS, AND MANAGEMENT OUTCOMES OF CURVULARIA ENDOPHTHALMITIS AND A REVIEW OF LITERATURE.

PURPOSE: To describe the clinical presentation and management of Curvularia endophthalmitis and compare with previous published literature. METHODS: Retrospective interventional comparative case series and literature review. Eight cases with culture-proven Curvularia endophthalmitis from January 2000 to March 2018 underwent vitrectomy/vitreous biopsy, intravitreal antibiotic with or without additional procedures as appropriate. The undiluted vitreous biopsy was subjected to microbiologic evaluation. Pre-existing literature was reviewed, and the current outcomes were compared with them. The mean age at presentation, etiology, number of interventions, interval between inciting event and presentation, type of intravitreal antifungal used, anatomical, and the functional outcomes were reported and compared with pre-existing literature. A favorable anatomical outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit. RESULTS: In the current series, there were 4 men and 4 women. Mean age at presentation was 34.5 ± 13.51 years (median 30 years). Inciting event was open-globe injury in five cases and cataract surgery, trabeculectomy, and endogenous cause in one case each. Presenting visual acuity was ≥20/400 in 3 cases at presentation and 5 cases at the last visit. One case with staphyloma and endophthalmitis underwent evisceration for a painful blind eye. The patients in the current series were much younger than those described previously. CONCLUSION: Presentation and diagnosis of Curvularia can be delayed especially in postoperative cases. Early and appropriate management with multiple interventions can result in an acceptable visual and anatomical outcome.

Endogenous endophthalmitis secondary to septic arthritis caused by group A Streptococcus infection: A case report and literature review.

Streptococcus pyogenes is a rare pathogen that causes endogenous endophthalmitis (EE). A healthy 58-year-old woman was diagnosed with EE secondary to septic arthritis caused by S. pyogenes. She underwent enucleation after hospitalization for 14 days with appropriate antibiotic cover. A literature search for outcomes of this condition revealed reports on only 10 eyes among 8 cases identified: 8 eyes (80%) developed poor visual outcome and 5 eyes (50%) underwent enucleation. There were no cases with immunocompromise. Our case report and literature review suggest the importance of awareness of the occurrence of S. pyogenes infection in immunocompetent hosts, and thus early diagnosis and aggressive treatment may be required to improve visual outcome.

Clinical analysis and predictive factors associated with improved visual acuity of infectious endophthalmitis.

BACKGROUND: To describe the clinical characteristics and analyze the predictive factors associated with improved visual acuity of 359 patients with infectious endophthalmitis. METHODS: This study retrospectively analyzed 359 eyes of 359 patients with infectious endophthalmitis from January 2014 to December 2018. The findings summarized some epidemiological characteristics of these patients, including age, sex, occupation, patient visit time, etiology, causative organisms, therapy, and best-corrected visual acuity. Multivariate logistic regression was performed to predict the relative factors of improved visual acuity (VA). RESULTS: Overall, 283 (78.83%) patients were male. The mean age was 48.0 ± 18.27 years. Ocular trauma, especially open globe injuries (246, 68.5%) was the most common etiology of infectious endophthalmitis in this study. The etiologies of infectious endophthalmitis were open globe injuries (68.5%), intraocular surgery (22.6%), and corneal ulcer-associated (6.7%) and endogenous causes (2.2%). In the etiology classification and visual acuity improvement group, had statistically significant differences in factors such as age, sex, patient visit time, pre-therapy visual acuity, etc. The average Logarithm of the Minimum Angle of Resolution (logMAR) best-corrected visual acuity on pre-therapy was 2.28 ± 0.60, and it had significantly improved to 1.67 ± 0.83 post-therapy (P < 0.05). Logistic regression analysis showed that visit time > 7 day (P = 0.034, OR = 0.522, 95% CI: 0.286-0.953), pre-therapy VA ≦logMAR 2.3 (P = 0.032, OR = 1.809, 95% CI: 1.052-3.110), post-surgical (vs. posttraumatic; P = 0.023, OR = 2.100, 95% CI: 1.109-3.974), and corneal ulcer-associated etiologies (vs. posttraumatic; P = 0.005, OR = 0.202, 95%CI: 0.066-0.621) were significantly associated with improved visual acuity after adjusting for possible confounding factors. CONCLUSIONS: Among the patients with infectious endophthalmitis, middle-aged male, especially farmers and workers, accounted for a large proportion. Open globe injuries were the main cause and the gram-positive bacteria were the major causative organisms. The final visual outcomes seemed to vary according to the type of endophthalmitis, but early treatment and good initial visual acuity were important factors for visual acuity improvement.

A case report of fulminant endophthalmitis caused by Streptococcus dysgalactiae in a patient with traumatic corneal laceration.

BACKGROUND: To report a case of enucleation caused by Streptococcus dysgalactiae endophthalmitis after traumatic corneal laceration. CASE PRESENTATION: A 69-year-old man with history of retinal detachment treated with vitrectomy and subsequent cataract surgery presented with traumatic corneal laceration while cutting grass. Appropriate repair of corneal laceration and intravitreal antibiotics (vancomycin, ceftazidime) injection was performed. S. dysgalactiae which was sensitive to the conventional antibiotics (Ampicillin, Ceftriaxone, Levofloxacin, etc.) detected by aqueous culture. One day following primary closure, the patient developed a complete hypopyon and vitreous membranes. Despite vigorous systemic and intravitreal antibiotics administration with vitrectomy, endophthalmitis was not controlled and patient's ocular pain was increased. The vitreous culture was also positive for S. dysgalactiae. Finally, total enucleation was performed 9 days after trauma due to fulminant endophthalmitis with severe scleritis. CONCLUSION: Progression of traumatic endophthalmitis associated with S. dysgalactiae can be fulminant. Sufficient warning to patient about enucleation and intensive care is needed in the case of this infection.
