Prophylactic Intracameral Antibiotics and Endophthalmitis After Cataract Surgery.

Importance: Although the effectiveness of intracameral antibiotics to prevent postoperative endophthalmitis is described, selective use of antibiotics combined with 1% povidone iodine disinfection might be equally effective and could lead to cost reduction and avoidance of unnecessary use of antibiotics.

Objective: To compare the incidence of postoperative endophthalmitis when 1% povidone iodine disinfection is applied in combination with selective intracameral antibiotics with the incidence after routine use of intracameral antibiotics in combination with 5% povidone iodine.

Design, Setting, And Participant: This was a retrospective cohort study using incidence data from the ongoing endophthalmitis register of the Rotterdam Eye Hospital, a specialized hospital providing both secondary and tertiary ophthalmological care, when intracameral antibiotics were used only during cataract procedures with occurrence of a posterior capsular tear in comparison with results from cohorts described in the literature where routine antibiotics were used.

Pediatric Endophthalmitis Over the Last Five Decades: A Case Report and Systematic Review.

Introduction: Pediatric infectious endophthalmitis is a rare, severe ocular infection that can have devastating consequences. It may be exogenous or endogenous, with exogenous endophthalmitis being more common. Current data on the etiology, microbiology, antibiotic treatments and outcomes in pediatric cases is limited.

Intravitreal conbercept injection with panretinal photocoagulation for high-risk proliferative diabetic retinopathy with vitreous hemorrhage.

Aim: To assess the clinical efficacy and safety of combining panretinal photocoagulation (PRP) with intravitreal conbercept (IVC) injections for patients with high-risk proliferative diabetic retinopathy (HR-PDR) complicated by mild or moderate vitreous hemorrhage (VH), with or without diabetic macular edema (DME).

Methods: Patients diagnosed with VH with/without DME secondary to HR-PDR and received PRP combined with IVC injections were recruited in this retrospective study. Upon establishing the patient's diagnosis, an initial IVC was performed, followed by prompt administration of PRP.

Transfer learning predicts species-specific drug interactions in emerging pathogens.

Machine learning (ML) algorithms are necessary to efficiently identify potent drug combinations within a large candidate space to combat drug resistance. However, existing ML approaches cannot be applied to emerging and under-studied pathogens with limited training data. To address this, we developed a transfer learning and crowdsourcing framework (TACTIC) to train ML models on data from multiple bacteria.

A rare case of hypervirulent Klebsiella pneumoniae liver abscess and bacterial endophthalmitis associated with distal bile duct cancer.

We report a case of a patient with distal bile duct cancer who presented with ocular pain and eye redness due to a liver abscess. The patient developed a liver abscess while waiting for surgery. Since Klebsiella pneumoniae with high viscosity was identified and imaging studies showed systemic infection, a diagnosis of klebsiella invasive syndrome was made.

The incidence of severe complications in acanthamoeba keratitis: Qualitative and quantitative systematic assessment.

Acanthamoeba keratitis (AK) is a rare, sight-threating corneal infection. The disease is challenging to diagnose and treat, and the amoeba can rapidly encyst, persisting in the tissue and causing recurrences. Medical therapy is conventionally considered the first line treatment, but advanced cases could require more invasive treatments like a "chaud" corneal transplant.

Clinical and pathogenic characteristics of infectious endophthalmitis in children: A retrospective analysis.

Infective endophthalmitis is an ophthalmic infection that in severe cases can cause complete loss of vision. In children, the defense against infection is low and eye tissue is not fully developed, leading to increased vulnerability to endophthalmitis. Children may be unable to understand the symptoms; thus, developing a method for prevention and treatment of this disease in children is important.

Efficacy and safety evaluation of Monoblue Dual View and Monoblue ILM View vital stains during vitrectomy surgery.

Purpose: To compare the staining properties of Monoblue inner limiting membrane (ILM) View and Monoblue DUAL View (study products) vital stains during vitrectomy surgery to those of ILM Blue or Membrane Blue Dual (control products).

Methods: In this study, 105 patients were included in the Ophthalmic Clinic of the University Hospitals Leuven from September 2021 to April 2022. For prospective data collection in this study, patients were randomized between a control group (ILM Blue or Membrane Blue Dual, manufactured and commercialized by DORC®) and a study group (Monoblue ILM View or Monoblue DUAL View, manufactured and commercialized by Arcadophta®-BVI®).

Bacteraemia associated with multiple septic localizations caused by Klebsiella pneumoniae sequence type ST660.

We report a case of Klebsiella pneumoniae bacteraemia in an 80-year-old man in France with no history of travel to Asia, complicated by endogenous endophthalmitis, multiple cerebral microbleeds and hepatic microabscesses, associated with a Bentall endocarditis. Hypervirulence pathotype was suggested based on clinical picture, bacterial isolate genomic sequence and hypermucoidy. Interestingly, the isolate had the non-K1/K2-capsular serotype locus KL113-like, carried a KpVP-1-like virulence plasmid, and belonged to the emerging sublineage SL660 (comprising the sequence type ST660).

The analysis encompassed evaluating patient age, gender, laterality, risk factors, infection origins, presenting and final visual acuity, microbial results, treatment responses, and factors affecting final visual outcomes.

Endogenous Endophthalmitis Caused by in an Immunocompromised Patient with Lung Cancer.

A 78-year-old man with a history of lung cancer, chemotherapy, radiotherapy, and coronavirus disease 2019 infection experienced visual deterioration of two-weeks’ duration in his right eye. There was multifocal, yellowish-white retinitis foci, vascular engorgement, and scattered intraretinal hemorrhages extending from posterior pole to retinal periphery in the right eye, whereas the left eye was normal. Intravitreal vancomycin, ceftazidime, clindamycin, and dexamethasone were given for endogenous endophthalmitis initially.

Anti-vascular endothelial growth factor biosimilars for neovascular age-related macular degeneration.

Rationale: Neovascular age-related macular degeneration (AMD) is a progressive eye disease characterized by choroidal neovascularization (CNV) and is a leading cause of vision loss and disability worldwide. Although intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy is an effective treatment option that helps to prevent vision loss or to improve visual acuity in people with neovascular AMD, treatment imposes a significant financial burden on patients and healthcare systems. A biosimilar is a biological product that has been developed to be nearly identical to a previously approved biological product.

Risk of post-injection endophthalmitis peaks within the first three injections of anti-vascular endothelial growth factor therapy: A nationwide registry-based study.

Purpose: To report the incidence of post-injection endophthalmitis (PIE) and the cumulative risk associated with repeated injections of intravitreal anti-vascular endothelial growth factor (anti-VEGF).

Methods: We employed nationwide registries in Denmark to include all individuals aged ≥40 years who received at least one intravitreal anti-VEGF injection in 2007-2022. Our primary endpoint PIE was identified using specific diagnostic codes for endophthalmitis and procedure codes for vitreous biopsy within 10 days prior to and 120 days post-injection.
