Evaluation of Outcomes of Acute Cataract Surgery-Related Endophthalmitis Using a Novel Management Algorithm Based on Presenting Risk Factors.

PURPOSE: Develop treatment algorithm for acute endophthalmitis (AE) following cataract surgery. METHODS: Retrospective single-center, non-randomized interventional study involving patients with AE divided into cohorts according to our novel scoring system, the Acute Cataract surgery-related Endophthalmitis Severity (ACES) score. Total score ≥3 points indicated need for urgent pars plana vitrectomy (PPV; within 24 hours), whereas <3 points indicated urgent PPV was unnecessary. Patients were retrospectively evaluated for visual outcomes based on whether their clinical course followed with or deviated from ACES score recommendations. Main outcome was best-corrected visual acuity (BCVA) at 6-month or longer after treatment. RESULTS: Total of 150 patients were analyzed. Patients whose clinical course followed the ACES score recommendation for immediate surgery had significantly (P < 0.01) better final BCVA (median = 0.18 logMAR, 20/30 Snellen) compared to those that deviated (median = 0.70 logMAR, 20/100 Snellen). For those where the ACES score deemed urgent PPV was unnecessary, no significant (P = 0.19) difference was observed between patients that followed with (median = 0.18 logMAR, 20/30 Snellen) and those that deviated from (median = 0.10 logMAR, 20/25 Snellen) recommendation. CONCLUSIONS: The ACES score may potentially provide critical and updated management guidance at presentation for when to recommend urgent PPV for patients suffering from post-cataract surgery AE.

[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.

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.

Fungal Endophthalmitis: Analysis of 730 Consecutive Eyes from 7 Tertiary Eye Care Centers in India.

PURPOSE: To evaluate the clinical and microbiological features of a large cohort with culture-confirmed fungal endophthalmitis across India. DESIGN: Cross-sectional, hospital-based, retrospective medical record review. PARTICIPANTS: Seven large tertiary eye care centers from different regions of India. METHODS: Patient data were pooled from electronic or physical medical records of each participating center. Fellowship-trained vitreoretinal specialists clinically managed all patients, and in-house microbiology laboratories performed all microbiological workups. The clinical and microbiological procedures were broadly uniform across all participating centers. The essential treatment consisted of vitreous surgery as well as intravitreal and systemic therapies with antifungal agents. MAIN OUTCOME MEASURES: Clinical outcome of the causative event and causative fungus. RESULTS: In the period from 2005 to 2020, 7 centers treated 3830 cases of culture-proven endophthalmitis, and of these, 19.1% (n = 730) were cases of culture-confirmed fungal endophthalmitis. It included 46.9% cases of postoperative (87.4% postcataract surgery), 35.6% of traumatic, and 17.5% of endogenous endophthalmitis. The fungi included 39.0% of Aspergillus (high prevalence in central, east, and south zones), 15.1% of Candida (high prevalence in west zone), and 15.9% of Fusarium (high prevalence in north and west zones). The time to symptom development was between 1 week and 4 weeks in more than one third of the patients, except in patients with traumatic endophthalmitis. Less than half of the patients had hypopyon on presentation. The presenting visual acuity (PVA) in most patients was <20/400. Nearly all patients needed vitrectomy and an average of 2 intravitreal injections of antifungal agents. At least 10% of eyes needed therapeutic keratoplasty, and up to 7% of eyes were eviscerated. After treatment, the final (best corrected) visual acuity (FVA) was >20/400 in 30.5% (n = 222) of eyes and >20/40 in 7.9% (n = 58) of eyes, and 12% (n = 88) of eyes lost light perception. A post hoc analysis showed the male sex to be significantly more associated with traumatic endophthalmitis than with postoperative (P < 0.0001) and endogenous (P = 0.001) endophthalmitis, more isolation of Candida species in patients with endogenous endophthalmitis than in those with postoperative (P = 0.004) and traumatic (P < 0.0001) endophthalmitis, better PVA in eyes with Candida species infection (P < 0.0001), and poorer FVA in eyes with Aspergillus species infection. CONCLUSIONS: Fungal endophthalmitis is not uncommon in India. The inclusion of antifungal agents with antibiotics as the first empirical intravitreal therapy before microbiological confirmation should be considered when a fungal infection is suspected.

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.

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.

Endophthalmitis Post Pars Plana Vitrectomy Surgery: Incidence, Organisms' Profile, and Management Outcome in a Tertiary Eye Hospital in Saudi Arabia.

PURPOSE: To determine the incidence of endophthalmitis after pars plana vitrectomy (PPV), organisms' profile, and management outcomes at a tertiary eye hospital in a Middle East country. METHODS: In this single-arm cohort study conducted in 2020, medical records of patients who underwent PPV not accompanied by any other intraocular surgery were reviewed; those with a diagnosis of acute endophthalmitis in the immediate postoperative period (within 6 weeks) during the past 6 years were analyzed. RESULTS: A total of 8153 records of PPV surgeries were reviewed. Five cases had endophthalmitis post-PPV with an incidence of 0.061%. Three (0.037%) had positive cultures, all of them for Staphylococcus epidermidis. The interval between PPV and diagnosis of endophthalmitis ranged from 3 to 25 days (mean, 15.8 days). Final vision after treatment ranged from 20/400 to no light perception, and one eye was eviscerated. CONCLUSION: The incidence of endophthalmitis post PPV is low. Despite prompt diagnosis and standard management, visual prognosis seems to be poor. The infective agents for endophthalmitis were commensals from the ocular surface.

Endophthalmitis management study. Report #1. Protocol.

To date, the Endophthalmitis Vitrectomy Study (EVS) has remained the hallmark of evidence-based management of acute bacterial endophthalmitis after cataract surgery with an intraocular lens. In the last quarter-century since its publication, several studies have reported that the microbiological spectrum of endophthalmitis is not the same across the world; there is emerging antibiotic resistance of gram-negative microorganisms to the EVS recommended antibiotics; there are newer molecules that could cross the blood-retinal barrier; the advances in vitreous surgery have become safer than before, and there are newer methods of microbiological evaluation. One of the often-mentioned drawbacks of the EVS was not recruiting grossly infected eyes with poor visibility of the iris and vitreous. Keeping these factors in mind, a new prospective multi-centered randomized study, the Endophthalmitis Management Study (EMS), is designed. The EMS will recruit all post-cataract surgery endophthalmitis patients irrespective of severity (including suspected fungal infection); the EMS will use quantifiable inflammatory score instead of the presenting vision to allocate for surgery, randomize the eyes to two different combinations of intravitreal antibiotics and use the newer microbiological diagnostic techniques. We believe the EMS findings will complement the EVS recommendations.

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.

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.

Rare case of endogenous Klebsiella endophthalmitis associated with emphysematous prostatitis in a patient with diabetes, cirrhosis and COVID-19.

A 35-year-old Hispanic man presented with fever, chills, dysuria, diarrhoea, scleral icterus, tachycardia and tachypnea. He was found to be COVID-19 positive, CT of the pelvis revealed prostatic abscess, and urine culture grew Klebsiella pneumoniae Additionally, he was found to have diabetes and cirrhosis. During treatment, the patient developed vision loss, and was diagnosed with endogenous Klebsiella endophthalmitis. The patient was treated with intravenous antibiotics, pars plana vitrectomy, intravitreal antibiotics and cystoscopy/suprapubic catheter placement. On follow-up, the patient has had the suprapubic catheter removed, and successfully passed a voiding trial, but suffers permanent vision loss in both eyes.

Chronic endogenous fungal endophthalmitis: diagnostic and treatment challenges: A case report.

RATIONALE: Endogenous fungal endophthalmitis (EFE) is a sight-threatening complication of systemic fungemia. As the prevalence rises, treatment remains a challenge especially when there is a failure in first-line treatment or drug-resistant fungus. This case report studies a case of chronic EFE, focusing on the diagnostic procedures, treatment options, monitoring parameters and the treatment outcome. PATIENT CONCERNS: A 64-year-old man with underlying well controlled diabetes mellitus was treated with 2 weeks' course of intravenous antifungal fluconazole for pyelonephritis as his blood culture grew Candida albicans. Concurrently, he complained of 3 months of bilateral painless progressive blurring of vision. At presentation, his visual acuity (VA) was light perception both eyes. Ocular examination revealed non granulomatous inflammation with dense vitritis of both eyes. DIAGNOSIS: He was diagnosed with EFE but the condition responded poorly with the medications. INTERVENTIONS: He was treated with intravitreal (IVT) amphotericin B and fluconazole was continued. Vitrectomy was performed and intraoperative findings included bilateral fungal balls in the vitreous and retina with foveal traction in the left eye. Postoperatively, vision acuity was 6/24, N8 right eye and 2/60, N unable for left eye with extensive left macular scar and hole. Vitreous cultures were negative. He received multiple IVT amphotericin B and was started on topical steroid eye drops for persistent panuveitis with systemic fluconazole. Ocular improvement was seen after switching to IVT and topical voriconazole. Despite this, his ocular condition deteriorated and he developed neovascular glaucoma requiring 3 topical antiglaucoma agents. Panretinal photocoagulation was subsequently performed. OUTCOMES: At 3 months' follow-up, his vision acuity remained at 6/24 for right eye and 2/60 for the left eye. There was no recurrence of inflammation or infection in both eyes. LESSONS: Voriconazole could serve as a promising broad spectrum tri-azole agent in cases of failure in first-line treatment or drug-resistant fungus.

Abordaje interdisciplinario de endoftalmitis endógena neonatal. Reporte de caso / Interdisciplinary approach to endogenous neonatal endophthalmitis. Case report

La endoftalmitis endógena neonatal es una patología poco frecuente que puede causar daño ocular grave. Puede manifestarse en pacientes con comorbilidades, como nacimiento pretérmino, bajo peso al nacer, complicaciones posquirúrgicas perinatales o sepsis.El presente reporte de caso documenta a una paciente pretérmino que fue sometida a múltiples cirugías abdominales. Durante su internación, desarrolló sepsis, meningitis y endoftalmitis endógena neonatal. La frecuencia extremadamente baja de la endoftalmitis endógena a esta edad, la importancia de preservar la salud visual del paciente y el abordaje interdisciplinario son puntos importantes de aprendizaje en este caso.

Neonatal endogenous endophthalmitis is a rare condition that can cause serious eye injuries. It can manifest in patients with comorbidities, such as preterm birth, low birth weight, post-surgical perinatal complications, or sepsis.This case report documents a preterm patient who underwent multiple abdominal surgeries. During her hospitalization, she developed sepsis, meningitis and neonatal endogenous endophthalmitis. The extremely low frequency of endogenous endophthalmitis at this age, the importance of preserving the patient's visual health, and the interdisciplinary approach are important learning points in this case.

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.

BILATERAL ENTEROCOCCUS FAECALIS ENDOPHTHALMITIS WITH MULTIPLE RECURRENCES.

PURPOSE: To describe the first case report of a bilateral recurrent Enterococcus faecalis endophthalmitis postcataract surgery. METHODS: Case report with a description of the timeline, diagnosis, and management of a patient with bilateral recurrent E. faecalis endophthalmitis. RESULTS: An 89-year-old man presented 6 weeks' postcataract surgery with pain, tearing, and blurred vision in the left eye. B-scan ultrasonography revealed vitritis and cultures postvitrectomy grew E. faecalis. There was gradual improvement in vision postintravitreal vancomycin administration. Four years later, the patient experienced another episode of E. faecalis endophthalmitis in the right eye postcataract extraction, followed by several additional episodes in both eyes posttreatment. CONCLUSION: Enterococcus faecalis is a rare but highly virulent cause of endophthalmitis that may remain sequestered in the capsular bag, despite aggressive treatment. Even after recurrent episodes, early vitrectomy and aggressive antibiotic therapy may prove to be effective in preventing vision loss.

Management Patterns and Visual Outcomes of Endophthalmitis After Glaucoma Drainage Device Placement: A Case Series.

PURPOSE: To describe clinical presentation, management, and outcomes of eyes with endophthalmitis related to glaucoma drainage device (GDD) placement. PATIENTS AND METHODS: Retrospective chart review of patients diagnosed with GDD-related endophthalmitis at Duke Eye Center from 2009 to 2018. RESULTS: Six eyes of 6 patients had endophthalmitis related to a GDD (2 Ahmed, 4 Baerveldt). The mean time from surgery to presentation was 22.7 months. Five of 6 cases (83%) had culture-proven infectious endophthalmitis. Eyes undergoing GDD explantation (n=2) had better visual acuity at 6 months compared with those without hardware removal (20/11,314 vs. 20/358). Visual acuity at 6 months was hand motion (20/8000) or worse in 3 of 6 cases (50%). CONCLUSIONS: GDD-related endophthalmitis often leads to poor visual outcomes. Hardware removal may lead to improved visual outcomes; a multicenter prospective study assessing the benefit of hardware removal may be warranted.

Endophthalmitis after Cataract Surgery: Changes in Management Based on Microbiologic Cultures.

PURPOSE: To assess the utility of microbiologic culture data for the management of endophthalmitis after cataract surgery. DESIGN: Retrospective, single-center, cohort study. PARTICIPANTS: All patients treated for endophthalmitis after cataract surgery between January 1, 2014, and December 31, 2017, at a single institution. METHODS: Endophthalmitis cases were determined from billing records and confirmed with chart review. A change in clinical management was defined as additional intravitreal antibiotic injections or pars plana vitrectomy. MAIN OUTCOME MEASURES: A change in clinical management within 2 weeks of initial endophthalmitis culture and treatment; visual acuity (VA). RESULTS: A total of 111 eyes of 111 patients were treated for endophthalmitis after cataract surgery, of which 57 (51%) were culture-positive. After initial treatment of endophthalmitis, a change in clinical management after vitreous culture occurred in 9 of 111 eyes (8%), including 6 of 57 (11%) culture-positive eyes compared with 3 of 54 (6%) culture-negative eyes (P = 0.49). Change in clinical management for culture-positive eyes was based on declining vision (3 eyes), worsening clinical examination results (2 eyes), and retinal detachment (1 case). Change in clinical management for culture-negative endophthalmitis eyes was based on worsening clinical examination results (2 eyes) and declining vision (1 eye). No additional interventions were initiated on the basis of positive culture results. At final follow-up, mean logarithm of the minimum angle of resolution (logMAR) VA was 1.09 (∼20/250) for the culture-positive eyes compared with 0.59 (∼20/80) for culture-negative eyes (adjusted difference, 0.394; 95% confidence interval, 0.02-0.77, P = 0.03). Rhegmatogenous retinal detachments (RRDs) or retinal tears occurred in 19 of 111 eyes (17%) after developing endophthalmitis, and culture-positive eyes developed a secondary RRD in 11 of 57 eyes (19%) compared with 3 of 54 (6%) culture-negative eyes (P = 0.03). CONCLUSIONS: After endophthalmitis related to cataract surgery, vitreous cultures may have prognostic value for final visual outcomes but have a limited effect on clinical management.

Clinical Course and Characteristics of Eyes with Recurrent Episodes of Endophthalmitis.

PURPOSE: Infectious endophthalmitis is a devastating, yet rare, complication after intraocular surgery, trauma, and systemic illness. Given its rare incidence, few patients would be expected to experience more than 1 episode of infectious endophthalmitis in their lifetime. We reviewed our patients who were diagnosed with and treated for at least 2 separate episodes of endophthalmitis. DESIGN: A retrospective, consecutive case series was conducted of patients managed at Associated Retinal Consultants PC (Royal Oak, Michigan) from January 2013 through December 2019. PARTICIPANTS: Patients were identified with the diagnosis of endophthalmitis by International Classification of Diseases, Ninth and Tenth Editions, codes. METHODS: Those diagnosed and then treated either with a vitreous tap and intravitreal injection of antibiotics or with pars plana vitrectomy at least twice were included. Those treated multiple times for the same episode of endophthalmitis were excluded. MAIN OUTCOME MEASURES: Cause and risk factors for recurrent endophthalmitis. RESULTS: Charts of 535 patients were reviewed, and 12 patients met inclusion criteria. The median age at initial presentation was 72.5 years, and 33.3% were men. Eight of the 12 patients (66%) experienced recurrent endophthalmitis in the same eye, and 4 of the 12 patients (33%) experienced separate episodes in different eyes. The average time between episodes was 604 days (range, 90-2366 days). The average follow-up from the second episode was 492 days (range, 119-1185 days). The most common cause for both the first and second episodes was recent intravitreal injection (50% and 58.3%, respectively) followed by surgery associated (41.6% and 33.3%, respectively). The cause was the same for the first and second episodes of 8 patients (75%). Of the 24 recorded episodes of endophthalmitis, culture results were positive in 41.6%, with coagulase-negative Staphylococcus being the most common bacteria identified. CONCLUSIONS: Recurrent endophthalmitis is rare and seen most commonly after intravitreal injections. Most patients in this series showed culture-negative results. Each successive episode of endophthalmitis was associated with a worse final visual outcome. The cumulative number of intravitreal injections may be an independent risk factor for recurrent postinjection endophthalmitis.

Ocular Phaeohyphomycosis Caused by Veronaea botryose: A Novel Fungal Infection in Human Beings.

PURPOSE: To describe an aggressive, refractory case of Veronaea botryosa-associated mycokeratitis progressing to endophthalmitis. METHODS: Observational case report and review of relevant literature. RESULTS: An 80-year-old man with a history of lung cancer and diabetes mellitus type 2 presented as an emergent referral to the corneal service with a corneal ulcer and associated endothelial plaque that responded initially to topical steroid and antiviral therapy but subsequently progressed to fungal endophthalmitis. The patient underwent an emergent penetrating keratoplasty and pars plana vitrectomy. Despite multiple negative Grocott methenamine silver smears, gram stains, eye cultures (aerobic, anaerobic, and fungal), and inconclusive confocal microscopy, the host corneal tissue pathology revealed melanin-containing fungi (phaeohyphomycosis). Further speciation of the pathology specimen revealed mold and phenotypic characterization and DNA sequencing confirmed V. botryose. CONCLUSIONS: Veronaea botryose is a rare fungal infection with previously reported human cutaneous, subcutaneous, and submucosal infections. This is the first documented case of phaeohyphomycosis caused by V. botryosa infection in human ocular tissue.
