PURPOSE: Intracameral cefuroxime (CXM) and antibiotic eye drops such as fluoroquinolone are widely used for preventing endophthalmitis after cataract surgery. However, few reports are available regarding their interactions. This study was conducted to examine the in vitro interaction of CXM and levofloxacin (LVFX) against bacterial isolates from the healthy conjunctival sac before cataract surgery and from endophthalmitis cases. METHODS: The activity of each drug was determined using a broth dilution method...

A man aged 77 years with postrenal transplant lymphoproliferative disease was admitted with high fever, elevated inflammatory markers and a heart murmur. Blood cultures grew Enterococcus faecalis and he was found to have mitral valve endocarditis on echocardiogram and subsequently started on appropriate antibiotics. 5 days into treatment, he developed ocular symptoms and 3 days later, he had irreversible monocular visual loss. He was seen by the ophthalmology team who diagnosed endogenous endopthalmitis secondary to bacteraemic spread from his endocarditis...

The purpose of this study was to investigate the spectrum of organisms causing endophthalmitis after cataract surgery in a tertiary medical center in Taiwan and the antibiotic susceptibilities. This was a retrospective case series study. Patients with endophthalmitis after cataract surgery from January 2004 to July 2015 were reviewed. The outcome measures included the identification of isolates, antibiotic susceptibilities, and final visual outcomes. Twenty-one organisms were isolated from 19 cases. The most common organisms were Enterococcus in 38...

PurposeTo investigate the relationship between the background of preoperative cataract patients and bacterial conjunctival flora.MethodsA total of 990 cataract patients who had completed preoperative examinations in 2007 and 2008 were included. Patients using topical antibiotics at the preoperative examination or having a history of intraocular surgery were excluded. Conjunctival cultures had been preoperatively obtained. Patient characteristics were investigated via medical records. Risk factors for conjunctival flora of seven typical bacteria were analyzed by univariate and multivariate analyses...

Catheter and/or arteriovenous (A-V) graft-related bacteremia is an important cause of morbidity and mortality among hemodialysis (HD) patients. Endocarditis, septic arthritis, epidural abscess, septic embolism, and osteomyelitis are the most common complications of catheter and/or A-V graft-related bacteremia; however, endogenous endophthalmitis is rarely seen. To the best of our knowledge, Enterococcus faecalis is the first case report in this population. We hereby report a case of endogenous endophthalmitis caused by E...

The aim of this study was to investigate the clinical features and treatment results of endophthalmitis after cataract surgery. Five patients with endophthalmitis after phacoemulsification with intraocular lens implantation were enrolled in this study. The pathogenesis, clinical manifestation, and surgical outcomes of 5 patients were compared. Three patients were surgically treated with anterior chamber irrigation and vitrectomy with intravitreal injection. The remaining two patients were medically treated with an intravitreal injection of vancomycin and ceftazidime...

PURPOSE: To evaluate the effects of different drug-delivery techniques for levofloxacin (LVFX) in ocular penetration and the prevention of endophthalmitis using an aphakic rabbit model with posterior capsule rupture (PCR). METHODS: LVFX was administered to aphakic rabbit eyes with or without PCR using eye drops (EDs), subconjunctival injection (SCI), or intracameral (IC) injection. The concentration of the drug in the vitreous and aqueous humors was estimated at 2 h after injection...

PURPOSE: To investigate the microorganisms in culture-proven endophthalmitis and their susceptibilities to antimicrobial agents commonly used in South Korea. METHODS: Medical records of consecutive patients with culture-proven endophthalmitis at eight institutions between 1 January 2004 and 31 July 31 2010 were reviewed. Four categories of endophthalmitis were studied: postoperative, posttraumatic, endogenous, and unspecified. Outcome measures were culture-proven infectious organisms, antimicrobial susceptibilities, and final visual acuity in the patients...

A three-year-old male neutered domestic shorthair cat was presented for loss of vision associated with hyperthermia, lethargy and anorexia. Ophthalmic examination revealed a bilateral panuveitis. Cytological examination of aqueous and vitreous humours was performed and revealed a suppurative inflammation associated with numerous cocci. Enterococcus faecalis was identified by bacterial culture from aqueous and vitreous humour. No primary infection site was identified. Active uveitis resolved after systemic antibiotic therapy, but the vision loss was permanent...

We report a case of a 74-year-old female, with a mitral heart valve, who presented with pain and blurred vision in the right eye for 2 days. Her visual acuity was light perception (LP) in the right eye and 20/40 in the left eye. Slit lamp examination showed corneal edema and hypopyon, and a view of the right fundus was impossible. Echography showed vitreous condensation. One day after presentation, the patient developed acute lung edema requiring hospitalization, so she was not submitted to vitreous tap and intravitreal treatment...

Enterococcus faecalis fsr quorum sensing (QS) involves an 11-residue cyclic peptide named gelatinase biosynthesis-activating pheromone (GBAP) that autoinduces two pathogenicity-related extracellular proteases in a cell density-dependent fashion. To identify anti-pathogenic agents that target fsr QS signaling, peptide antagonists of GBAP were created by our unique drug design approach based on reverse alanine scanning. First of all, a receptor-binding scaffold (RBS), [Ala(4,5,6,8,9,11)]Z-GBAP, was created, in which all amino acids within the ring region of GBAP, except for two essential aromatic residues, were substituted to alanine...

PURPOSE: The development of endophthalmitis after cataract surgery often results in significant vision loss. Inhibition of bacterial proliferation in the anterior chamber using antibiotic eye drops is important to prevent endophthalmitis after cataract surgery. We aimed to determine the sensitivity of fluoroquinolones against Enterococcus faecalis ocular isolates and the efficacy of fluoroquinolones to prevent E. faecalis-induced endophthalmitis in aphakic rabbits. METHODS: The minimum inhibitory concentrations (MICs) of moxifloxacin (MFLX) and levofloxacin (LVFX) used in ophthalmic solutions for 13 E...

PURPOSE: To report the occurrence of endophthalmitis after trabeculectomy for glaucoma that was treated by vitrectomy without bleb closure and recurred 3 times after an initial clinically inapparent period of about 2 years. METHODS: Interventional case report and short review of the pertinent literature. RESULTS: A 73-year-old Caucasian female underwent trabeculectomy (without mitomycin) for glaucoma. Four years after the trabeculectomy, an endophthalmitis with Staphylococcus epidermidis as the causative organism occurred and was treated with a pars plana vitrectomy (20-gauge) and a combined antibiotic and anti-inflammatory drug regimen...

PURPOSE: To assess the efficacy of vitrectomy combined with intravitreal injection in the treatment of endophthalmitis after phacoemulsification and IOL implantation. METHODS: Five patients (5 eyes), who had undergone conventional phacoemulsification combined with IOL implantation at another treatment facility, presented with endophthalmitis. The subjects ranged in age from 41 to 79 years (65.8 ± 0.5 years on average), and three were male. All five cases received bacterial culture susceptibility testing...
