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®). For retrospective data collection, patients were divided into similar surgery groups. Efficacy was analyzed using a binary subjective evaluation of the visualization of stained membranes during vitrectomy. The rate and severity of potential adverse events related to the study products were tracked, allowing both treatment groups to be compared with the corresponding control groups (ILM Blue and Membrane Blue Dual). RESULTS: Based on the results and findings, none of the comparisons (primary outcomes) were statistically significant, showing similar efficacy of the dyes used. The study products were found to be safe in this study since no serious adverse events were reported. CONCLUSIONS: The present findings indicate that the Monoblue ILM View and Monoblue DUAL View dyes can safely be used during vitrectomy to stain the ILM and/or epiretinal membrane (ERM) when removal is needed.

Efficacy and safety of the implantation of a single-piece angulated foldable IOL in the sulcus.

PURPOSE: To study the visual results and tolerance of a Zeiss CT Lucia 601P intraocular lens (IOL) implanted in the sulcus after complicated cataract surgery or during IOL exchange for clouded IOL. METHODS: In total, 64 patients who underwent sulcus implantation were recalled to the hospital to undergo subjective and objective refraction, best corrected visual acuity measurement, tonometry, optical coherence tomography, laser flare photometry, biometry, and wavefront aberrometry. RESULTS: In spite of a large variation in preoperative refraction, the target refraction was obtained within 1.5 diopters in approximately 97% of patients and within 0.5 diopter in 53% of patients. Average BCVA was high (Snellen 0.86) and related to concomitant (mostly retinal) pathologies in eyes with poorer visual performance. Wavefront aberrometry showed no evidence of IOL tilting or decentration after long-term implantation in the sulcus. Tonometry was not different from the fellow eye of the patient (p > 0.5). In 53 patients with bilateral pseudophakia, the laser flare photometry was not significantly different from the fellow eye (p < 0.05). CONCLUSION: This study demonstrates that this single-piece angulated foldable acrylic IOL can be considered for implantation in the sulcus. The visual results are favorable, and the IOL can be well-positioned and tolerated in the sulcus. Moreover, there were no safety issues found since there was no evidence of elevated IOP or chronic uveitis.

Patient satisfaction after EDOF intraocular lens implantation in vitrectomized eyes.

PURPOSE: To report patient satisfaction after unilateral/bilateral extended depth-of-focus (EDOF) intraocular lens (IOL) implantation in a young population after vitrectomy. METHODS: Patients that underwent phaco-vitrectomy or phaco following vitrectomy with an AT LARA EDOF IOL, aged between 18 and 75 years, were asked to fill out a questionnaire to assess overall visual quality, near vision quality, and visual disturbances. The questionnaire was based on the Catquest, NAVQ, and APPLES questionnaires. RESULTS: A total of 89 participants (average age 56.7 years) filled out the questionnaire of which 53.9% received a unilateral EDOF IOL. The most common indications for vitrectomy were retinal detachments (38.2%), floaters (36.0%), and epiretinal membranes (16.9%). The Catquest and NAVQ score respectively showed a good overall satisfaction (3.44/4.0), a good intermediate vision (3.55/4.0), and an average near vision (2.75/4.0). The APPLES score showed acceptable visual disturbances. There were no differences between the unilateral and bilateral group, except for a higher spectacle dependency in the unilateral group (40% vs. 10.6%). Participants that underwent vitrectomy in case of floaters reported lower satisfaction rates. Other variables, like the pre-operative refraction, had no impact on both satisfaction and visual disturbances. CONCLUSION: Both unilateral and bilateral implantation of the AT LARA EDOF IOL showed a high satisfaction with no differences between both groups, except for a lower spectacle use in the latter. Hence, The AT LARA seems to be a possible choice in patients undergoing vitrectomy at a younger age, even for unilateral use.

Efficacy and safety of abatacept to treat active birdshot uveitis: a prospective open label interventional proof-of-concept trial.

BACKGROUND/AIMS: Birdshot uveitis (BU) is a chronic autoimmune posterior uveitis, mostly affecting middle-aged Caucasians. There is a strong association with HLA-A29 and T-cell activation. Safety and efficacy of abatacept, an inhibitor of T-cell costimulation, is tested in active BU. METHODS: Fifteen patients with active BU were treated with monotherapy of weekly subcutaneous injections of abatacept 125 mg/mL. Time-to-treatment failure was evaluated as a primary outcome. The secondary objective was to evaluate the utility of different outcome measures to monitor disease activity. Safety was evaluated by adverse event reporting and serial blood analyses. RESULTS: At the year-1 endpoint, there was significant improvement in vitreous haze grade (p=0.0014), central choroidal thickness (CCT) (p=0.0011), Fluorescein Angiography (FA) Score (p=0.0014), Indocyanine Green Angiography (ICGA) Score (p<0.001) and total dual FA-ICGA Score (p<0.001). Best corrected visual acuity (BCVA) (p=0.8354) and central retinal thickness (CRT) (p=0.3549) did not change significantly. There were no serious adverse events reported. In total, 4 out of 15 patients left the trial during year 1 of whom 2 experienced treatment failure. CONCLUSIONS: Abatacept is very efficacious to treat both retinal vasculitis and choroiditis in patients with BU and is well tolerated. BCVA and CRT are inadequate to monitor disease activity. On the other hand, CCT is a promising non-invasive tool to detect treatment response in early active BU and dual FA-ICGA Score is very helpful to evaluate retinal vasculitis and choroiditis quantitatively. TRIAL REGISTRATION NUMBER: NCT03871361.

A new small molecule DHODH-inhibitor [KIO-100 (PP-001)] targeting activated T cells for intraocular treatment of uveitis - A phase I clinical trial.

Uveitis is a T cell-mediated, intraocular inflammatory disease and one of the main causes of blindness in industrialized countries. There is a high unmet need for new immunomodulatory, steroid-sparing therapies, since only ciclosporin A and a single TNF-α-blocker are approved for non-infectious uveitis. A new small molecule inhibitor of dihydroorotate dehydrogenase (DHODH), an enzyme pivotal for de novo synthesis of pyrimidines, has a high potency for suppressing T and B cells and has already proven highly effective for treating uveitis in experimental rat models. Systemic and intraocular application of KIO-100 (PP-001) (previously called PP-001, now KIO-100) could efficiently suppress rat uveitis in a preventive as well as therapeutic mode. Here we describe the outcome of the first clinical phase 1 trial comparing three different doses of a single intraocular injection of KIO-100 (PP-001) in patients with non-infectious posterior segment uveitis. No toxic side effects on intraocular tissues or other adverse events were observed, while intraocular inflammation decreased, and visual acuity significantly improved. Macular edema, a sight-threatening complication in uveitis, showed regression 2 weeks after intraocular KIO-100 (PP-001) injection in some patients, indicating that this novel small molecule has a high potential as a new intraocular therapy for uveitis. Clinical trial registration: [https://www.clinicaltrials.gov/ct2/show/NCT03634475], identifier [NCT03634475].

Late-onset toxic anterior segment syndrome after possible aluminum-contaminated and silicon-contaminated intraocular lens implantation.

PURPOSE: To describe an outbreak of late-onset toxic anterior segment syndrome (TASS) after the implantation of a specific hydrophilic acrylic intraocular lens (IOL). SETTING: University Hospitals of Leuven, Belgium. DESIGN: Retrospective, single-center, observational study. METHODS: All eyes undergoing cataract surgery with a monofocal, toric, or enhanced depth-of-focus (EDoF) Synthesis (Cutting Edge) IOL between August 2019 and March 2020 were reviewed. Data were collected on the surgical procedure, postoperative course, time until onset of symptoms, clinical features, and additional treatments. A laboratory surface analysis of all 3 IOL subtypes was performed in the Intermountain Ocular Research Center at the University of Utah, USA. Furthermore, other possible causes of prolonged postoperative inflammation rather than the IOL itself were investigated. RESULTS: Among the 203 eyes included, 28 TASS cases were identified (13.8%), among which 25 received a monofocal IOL, and 3 received an EDoF IOL. The mean time until onset was 28.9 (±19.9) days. Patients presented with anterior chamber cells (92.9%), deposits on the IOL (57.1%), or fibrinous inflammation (35.7%). 4 eyes (14.3%) underwent a surgical intervention, whereas 24 eyes showed a resolution of inflammation with topical therapy alone. Laboratory analysis showed the presence of both aluminum and silicon particles on the monofocal IOL, silicon particles only on the EDoF IOL, and no particles on the toric IOL surface. CONCLUSIONS: This report describes an outbreak of atypical, late-onset TASS after cataract surgery, possibly correlated with aluminum and silicon contamination of the IOL surfaces.

Analysis of Vitreous Samples by the Cellient® Automated Cell Block System: A Six-year Review of Specimens in a Uveitis Population.

PURPOSE: To further evaluate the value of a standardized method to analyze vitreous samples using the Cellient® automated cell block system in the diagnosis of unsolved uveitis. METHODS: Six hundred sixty-four pure vitreous samples obtained from patients with unsolved uveitis between March 2012 and May 2018 at University Hospitals Leuven, fixed in PreservCyt® and processed by the Cellient tissue processor, were included in the study. RESULTS: n 86.3% of the cases, sufficient material was found for diagnosis. A diagnosis of acute inflammation was made in 20.2% of the cases. In 34.0% of the cases, the diagnosis was chronic active inflammation; in 26.5%, low-grade inflammation; and in 5.6%, a malignant process. CONCLUSION: Our standardized protocol can be used to diagnose endophthalmitis, lymphoma, granulomatous disease, inactive and storage disease, and metastatic infiltration. Cellient analysis of vitreous specimens had a diagnostic yield of 86.3% in unsolved uveitis cases.

Long-Term Safety and Efficacy of Adalimumab in Patients with Noninfectious Intermediate Uveitis, Posterior Uveitis, or Panuveitis.

PURPOSE: To evaluate long-term efficacy and safety of extended treatment with adalimumab in patients with noninfectious intermediate, posterior, or panuveitis. DESIGN: Open-label, multicenter, phase 3 extension study (VISUAL III). PARTICIPANTS: Adults who had completed a randomized, placebo-controlled phase 3 parent trial (VISUAL I or II) without treatment failure (inactive uveitis) or who discontinued the study after meeting treatment failure criteria (active uveitis). METHODS: Patients received subcutaneous adalimumab 40 mg every other week. Data were collected for ≤ 362 weeks. Adverse events (AEs) were recorded until 70 days after the last dose. MAIN OUTCOME MEASURES: Long-term safety and quiescence; other efficacy variables included inflammatory lesions, anterior chamber cell and vitreous haze grade, macular edema, visual acuity, and dose of uveitis-related systemic corticosteroids. RESULTS: At study entry, 67% of patients (283/424) showed active uveitis and 33% (141/424) showed inactive uveitis; 60 patients subsequently met exclusion criteria, and 364 were included in the intention-to-treat analysis. Efficacy variables were analyzed through week 150, when approximately 50% of patients (214/424) remained in the study. Patients showing quiescence increased from 34% (122/364) at week 0 to 85% (153/180) at week 150. Corticosteroid-free quiescence was achieved by 54% (66/123) and 89% (51/57) of patients with active or inactive uveitis at study entry. Mean daily dose of systemic corticosteroids was reduced from 9.4 ± 17.1 mg/day at week 0 (n = 359) to 1.5 ± 3.9 mg/day at week 150 (n = 181). The percentage of patients who achieved other efficacy variables increased over time for those with active uveitis at study entry and was maintained for those with inactive uveitis. The most frequently reported treatment-emergent AEs of special interest were infections (n = 275; 79 events/100 patient-years [PY]); AEs and serious AEs occurred at a rate of 396 events/100 PY and 15 events/100 PY, respectively. CONCLUSIONS: Long-term treatment with adalimumab led to quiescence and reduced corticosteroid use for patients who entered VISUAL III with active uveitis and led to maintenance of quiescence for those with inactive uveitis. AEs were comparable with those reported in the parent trials and consistent with the known safety profile of adalimumab.

Endogenous Endophthalmitis Caused by Isolated Listeria Monocytogenes Infection.

Purpose: The purpose of this report is to present an extremely rare case of endogenous Listeria monocytogenes endophthalmitis.Methods: A 72-year-old woman was diagnosed with endogenous endophthalmitis. Listeria monocytogenes was identified by culture of aqueous humor. Multiple investigations could not reveal any source of infection. An overview of other published cases is presented and a standardized treatment protocol is suggested.Results: Treatment consisted of topical therapy with antibiotics, corticosteroids, cycloplegics, and intraocular pressure-lowering agents, four intravitreal injections of vancomycin, an anterior chamber washout, intravenous amoxicillin, and eventually a pars plana vitrectomy. The inflammation subsided and the patient was discharged with a best-corrected visual acuity of 20/40.Conclusion: Our study emphasizes the importance of adequate microbiological testing and initiating appropriate treatment early in the management of endogenous endophthalmitis.

How a Devastating Case of Acanthamoeba Sclerokeratitis Ended up with Serious Systemic Sequelae.

A 35-year old soft contact lens wearer with a proven bilateral Acanthamoeba keratitis developed a nodular scleritis. Based on the stepladder approach described by Iovieno et al. [Ophthalmology. 2014 Dec;121(12):2340-7], nonsteroidal anti-inflammatory drugs, methylprednisolone, and later azathioprine were added to the antiamoebic treatment. Unfortunately, there was further deterioration and an endophthalmitis developed. Unbearable pain and concerns of spread to the brain urged an enucleation. Histopathological examination confirmed Acanthamoeba cysts in the cornea, sclera, retina, choroid, and vitreous body. As a side effect of the immunosuppressive treatment, the patient developed myopathy, pulmonary aspergillosis, and an avascular necrosis of the hip. Scleritis is a devastating complication of Acanthamoeba keratitis with a poor prognosis and a high enucleation rate. Acanthamoeba sclerokeratitis is, due to cyst-free biopsies, mostly assigned to an immune-mediated mechanism, justifying the use of immunosuppressive treatment. Scleritis in our case contributed to the extracorneal spread of Acanthamoeba. Our case is the first documented extracorneal spread of Acanthamoeba without previous surgery. Extracorneal spread of Acanthamoeba should be considered, even in the case of false-negative biopsies. We strongly recommend serial sections of the retrieved scleral specimen in case of negative histopathological examination to exclude an infection. Even when an immune-mediated scleritis is suspected, systemic immunosuppressive treatment should always be used with the greatest caution. Awareness of the side effects and monitoring by an experienced physician is mandatory.

A Retrospective Case Series of Uveal Effusion Syndrome.

PURPOSE: This study aimed to describe the clinical findings and management of eyes affected by uveal effusion syndrome. METHODS: We retrospectively evaluated the charts of 13 eyes of 8 consecutive patients diagnosed with uveal effusion syndrome attending the Ophthalmology Unit of the University Hospitals Leuven, Belgium, between 2007 and 2018. The presenting features, investigations, management, and outcomes were analyzed for each case. RESULTS: Cataract surgery was the predisposing factor for uveal effusion in 6 eyes, 2 bilateral uveal effusions (4 eyes) were considered to be medication-induced, and in 3 eyes, the uveal effusion was described as idiopathic. Fundus examination of 5 of 13 eyes showed bullous choroidal detachment, treated with pars plana vitrectomy with superotemporal sclerectomy or transscleral punction. Fundoscopy showed uveal effusion without serous retinal detachment in 3 eyes. Serous retinal detachment accompanied by uveal swelling was observed in 3 eyes and the 2 remaining eyes presented with uveal swelling only. The 8 nonbullous choroidal detachments were treated in a conservative way. A rapid resolution of subretinal fluid and uveal effusion was observed in all cases. CONCLUSIONS: A conservative approach with acetazolamide treatment or just observation was used in our case series in choroidal detachment without substantial visual loss if, over time, slow improvement was documented. However, further studies are needed to verify the effectiveness of the reported therapy.

Primary vitreous cysts.

Objective: To report two cases of vitreous cysts with discussion of their pathophysiology and management. Methods: Clinical examination with fundus photography, ultrasound and optical coherence tomography. Histopathology was performed in the first case. Results: The first case illustrates a pigmented, free-floating cyst, which was removed during a 27-gauge vitrectomy. The histopathology shows a single layer of pigmented epithelium and confirms the previously reported presence of a PAS-positive basement membrane. The second case shows a sessile, non-pigmented cyst associated with significant anisometropia. Conclusion: Primary vitreous cysts are rare and can have a wide range in their clinical aspect. This likely reflects whether they originate either from the pigment epithelium or the primary hyaloidal system. The management of vitreous cysts is mostly conservative, but pars plana vitrectomy can be used safely if the symptoms are debilitating.

Co-occurrence of bilateral nodular anterior scleritis and large-vessel arteritis in a patient with TINU syndrome.

We present a case of tubulointerstitial nephritis and uveitis (TINU) with nodular anterior scleritis and large-vessel arteritis. A 67-year-old patient was admitted to the hospital with high fever, thoracic pain, and weakness. Bilateral anterior uveitis was seen at that time. Laboratory examination showed acute renal failure. A renal biopsy was performed and showed pathognomonic signs of tubulointerstitial nephritis (TIN). Six months later, she developed ocular inflammation suggestive of nodular scleritis. One year after hospital admission, she presented with large-vessel arteritis. We describe a case of TINU with co-occurrence of scleritis and large-vessel arteritis.

Uveal Melanoma: A European Network to Face the Many Challenges of a Rare Cancer.

Uveal melanoma (UM) is the most frequent primary ocular cancer in adults, accounting for 5% of all melanomas. Despite effective treatments for the primary tumour, up to 50% of UM patients will develop metastasis, leading to a very poor prognosis and a median overall survival of 6 to 12 months, with no major improvements in the last 30 years. There is no standard oncological treatment available for metastatic UM patients, and BRAF/MEK and immune checkpoint inhibitors show disappointing results when compared to cutaneous melanoma (CM). Recent advances in biology, however, identified specific gene and chromosome alterations, potentially permitting an actively tailored surveillance strategy, and dedicated clinical studies. Being a rare cancer, UM patients have to overcome issues such as identifying referral centres, having access to information, and partnering with oncologists for specific management strategies and research priorities. Here, we describe how the EUropean Rare Adult solid CAacer Network (EURACAN) will help in addressing these challenges and accelerating international collaborations to enhance the development of innovative treatments in UM.

Standardized care by redesign of an intravitreal injection pathway.

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.

Efficacy of Multiple Dexamethasone Intravitreal Implants for Refractory Retinal Vein Occlusion-Related Macular Edema and Effect of Prior Vitrectomy.

Purpose: To evaluate the efficacy of dexamethasone intravitreal implants (DEX implant) in patients with treatment-resistant macular edema (ME) owing to branch and central retinal vein occlusion (BRVO/CRVO), and the influence of prior vitrectomy on this treatment. Methods: Multicenter retrospective chart review was performed on 40 CRVO and 32 BRVO eyes with persistent ME despite intravitreal anti-vascular endothelial growth factor agents and/or intravitreal triamcinolone, and/or laser therapy. Each patient received ≥1 dexamethasone 700 µg implant between March 2011 and December 2015. Thirteen patients underwent prior vitrectomy. Data were collected on best-corrected visual acuity (BCVA), central macular thickness (CMT), time to relapse, and adverse events. Results: At the end of follow-up, BRVO eyes had a lesser CMT reduction from baseline compared to CRVO eyes (-122.50 ± 152.47 µm and -202.26 ± 194.09 µm, respectively). Neither BRVO nor CRVO eyes had a sustained BCVA benefit (P = 0.7041 and P = 0.7027, respectively). Vitrectomized and nonvitrectomized eyes overall had a sustained significant CMT reduction throughout the study with -192.46 ± 172.62 µm and -164.02 ± 180.36 µm, respectively, at final follow-up. Similar time to relapse of 24.4 ± 6.5 and 23.3 ± 13.5 weeks, respectively, was observed. By the end of follow-up, BCVA had only improved in vitrectomized eyes. However, multivariable regression analyses showed no significant association between vitrectomy status and CMT or BCVA change after the first and last injection. Cataract formation and ocular hypertension occurred in 25% and 17%, respectively. Conclusions: Multiple DEX implant are effective in reducing CMT in patients resistant to previous treatments and appear to be similarly effective in vitrectomized and nonvitrectomized eyes.

Safety and Efficacy of Adalimumab in Patients with Noninfectious Uveitis in an Ongoing Open-Label Study: VISUAL III.

PURPOSE: To evaluate safety and efficacy of adalimumab in patients with noninfectious intermediate, posterior, or panuveitis. DESIGN: Phase 3, open-label, multicenter clinical trial extension (VISUAL III). PARTICIPANTS: Adults meeting treatment failure (TF) criteria or who completed VISUAL I or II (phase 3, randomized, double-masked, placebo-controlled) without TF. METHODS: Patients received adalimumab 40 mg every other week. Interim follow-up data were described from VISUAL III weeks 0 through 78. MAIN OUTCOME MEASURES: Disease quiescence, steroid-free quiescence, active inflammatory chorioretinal/retinal vascular lesions, anterior chamber cell grade, vitreous haze grade, best-corrected visual acuity (BCVA), and corticosteroid dose. Binary data were reported using nonresponder imputation (NRI), continuous data using last observation carried forward and as-observed analysis, and corticosteroid dose using observed-case analysis. Adverse events (AEs) were reported from first adalimumab dose in VISUAL III through interim cutoff. RESULTS: Of 424 patients enrolled, 371 were included in intent-to-treat analysis. At study entry, 242 of 371 (65%) patients had active uveitis; 60% (145/242, NRI) achieved quiescence at week 78, and 66% (95/143, as-observed) of those were corticosteroid free. At study entry, 129 of 371 (35%) patients had inactive uveitis; 74% (96/129, NRI) achieved quiescence at week 78, and 93% (89/96, as-observed) of those were corticosteroid free. Inflammatory lesions, anterior chamber grade, and vitreous haze grade showed initial improvement followed by decline in patients with active uveitis and remained stable in patients with inactive uveitis. BCVA improved in patients with active uveitis from weeks 0 to 78 (0.27 to 0.14 logMAR; left and right eyes; as-observed) and remained stable in patients with inactive uveitis. Mean corticosteroid dose decreased from 13.6 mg/day (week 0) to 2.6 mg/day (week 78) in patients with active uveitis and remained stable in those with inactive uveitis (1.5-1.2 mg/day). AEs (424 events/100 patient-years) and serious AEs (16.5 events/100 patient-years) were comparable with previous VISUAL trials. CONCLUSIONS: Patients with active uveitis at study entry who received adalimumab therapy were likely to achieve quiescence, improve visual acuity, and reduce their daily uveitis-related systemic corticosteroid use. Most patients with inactive uveitis at study entry sustained quiescence without a systemic corticosteroid dose increase. No new safety signals were identified.

More Than Meets the Eye: Klebsiella pneumoniae Invasive Liver Abscess Syndrome Presenting with Endophthalmitis.

BACKGROUND: Endophthalmitis is a feared complication of pyogenic liver abscesses caused by hypervirulent Klebsiella pneumoniae strains. First described in East Asia in the 1980s, this invasive syndrome is only recently emerging in Europe and America. CASE REPORT: We describe an 84-year-old man who presented to the emergency department with fever, orbital cellulitis, and bilateral visual loss. Although the patient had no overt abdominal symptoms, computed tomography scan revealed a pyogenic liver abscess. Blood cultures were positive for K. pneumoniae. Initial treatment consisted of intravenous ceftriaxone and intravitreal ceftazidime. A unilateral vitrectomy was performed. The patient survived with severe visual sequelae. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: K. pneumoniae pyogenic liver abscess with metastatic endophthalmitis is a relatively new syndrome that should be considered in patients presenting with acute vision loss who appear septic, with or without abdominal complaints. Early recognition prohibits delays in lifesaving treatment.
