Spot the signs, save the sight: pediatric orbital cellulitis from rhinosinusitis

Orbital cellulitis is a potentially devastating condition characterized by acute infection of the orbital contents. While it can occur at any age, it is more prevalent in the pediatric population. Key red flag signs include conjunctival chemosis, proptosis, restricted ocular movements, and reduced visual acuity. Recognizing these signs is crucial for diagnosing post-septal cellulitis, which requires aggressive management involving surgical intervention and parenteral antibiotics to prevent serious complications. This case series presents 8 cases of orbital cellulitis encompassing 3 boys and 5 girls aged 3 to 15 years who were thoroughly assessed, investigated and followed up. Three patients who presented with pre-septal cellulitis were managed conservatively with antibiotics, antihistamines and nasal decongestants while the remaining five who presented with post-septal cellulitis underwent transnasal endoscopic orbital decompression surgery. Post-operative recovery was good. All patients are currently asymptomatic and are under follow-up.

Epidemiology of Orbital and Preseptal Cellulitis in the United States: A 13-Year Analysis

ABSTRACT Purpose: To determine the incidence rates, risk factors, and economic burden of orbital and preseptal cellulitis in the United States (US). Methods: This retrospective longitudinal study was completed using data from the US Nationwide Emergency Department Sample dataset. An estimated 732,105 emergency department (ED) visits with a primary or secondary diagnosis of orbital and preseptal cellulitis from 2006 to 2018 were included. Incidence rates, descriptive statistics, and risk factors were calculated using linear and multivariate logistic regression models. Results: The incidence rates of preseptal cellulitis increased from 6.2 in 2006 to 19.2 per 100,000 US population in 2018. In contrast, orbital cellulitis incidence rates have been decreasing from 6.1 to 2.8 per 100,000 US population from 2006 to 2018, respectively. Young adults (ages 21–44) comprise a majority of patients with either preseptal or orbital cellulitis (31.7%; 95% CI, 30.5–33.0%). Hypertension (11.8%, 12.9%), tobacco use (11.2%, 9.6%), and sinusitis (9.2%, 4.3%) were the most commonly associated diagnoses for orbital and preseptal cellulitis, respectively. Only 27.6% of patients with orbital cellulitis were admitted with 64.7% of patients routinely discharged. The inflation-adjusted ED charges for patients with orbital and preseptal cellulitis from 2006 to 2018 totalled over $997 million. Conclusion: Orbital and preseptal cellulitis are costly infections in the US with increasing incidence rates for preseptal cellulitis. High rates of routine discharge from the ED for orbital cellulitis may represent a knowledge gap amongst providers and an opportunity to improve care. Identifying individuals at risk for infection is key for diagnosis and appropriate triage of care.

Dentigerous Cyst masquerading as Lacrimal Sac Diverticulitis

Introduction: Dentigerous cysts (DCs) involving the orbit are extremely rare. The authors report a unique case of stand-alone orbital dentigerous cyst associated with ectopic canine tooth masquerading as a lacrimal sac diverticulitis with superadded preseptal cellulitis. Case presentation: A 21 – year – old lady presented with left inferomedial swelling, associated with pain and redness of 1-week-duration. A lacrimal sac diverticulitis with preseptal cellulitis was suspected and imaging was requested in view of progression. Computed Tomography (CT) scan of orbit revealed a well-defined heterogenous mass, with associated hyperdense lesion within the mass, prompting a possibility of a foreign body granuloma. Surgical exploration and excision confirmed the diagnosis of an ectopic canine tooth with associated DC along with excessive adhesion of the cyst to the lacrimal sac wall. Maxillary sinus did not show any abnormality. Lacrimal irrigation was patent with no recurrence noted at 6 – month followup. Conclusion: This report highlights the presentation of DC with associated ectopic canine tooth as an isolated orbital mass, initially manifesting as pre-septal cellulitis with lacrimal sac diverticulitis. Recurrent episodes of infection can lead to synechiae formation, rendering adjacent lacrimal sac more prone to injury. Cyst excision with meticulous dissection yields good outcome.

Preseptal cellulitis in an advanced case of Ludwig’s angina

Ludwig’s angina is known to be diffuse, life-threatening cellulitis that usually involves the submandibular, sublingual, and submental spaces. Prompt diagnosis and management can be a life-saving procedure. Nowadays, Ludwig’s angina is a fairly rare disease, as well as its ocular manifestations. We reported an advanced case of Ludwig’s angina due to a widespread from odontogenic bacterial infection, with one example of its clinical manifestations is periorbital cellulitis, which also known as preseptal cellulitis. A multidisciplinary approach to diagnosis and treatment was carried out in conjunction with the otolaryngology-head and neck surgery department as well as the thoracic cardiac and vascular surgery department. Unfortunately, this disease progresses so rapidly and eventually caused a mortality.

Factors Associated With Early Computed Tomography Imaging in Children Hospitalized With Severe Orbital Infections.

We identified factors associated with computed tomographic (CT) imaging within 24 hours of emergency department (ED) presentation in hospitalized children with severe orbital infections. A multicenter retrospective cohort study was conducted that included children aged 2 months to 18years between 2009 and 2018 who were admitted to the hospital with severe orbital infections, including periorbital and orbital cellulitis. Multivariable modified Poisson regression was used to identify possible factors associated with receiving a CT scan within 24 hours of ED presentation. Of 1144 children, 494 (43.2%) received a CT scan within 24 hours of ED presentation. Factors associated with receiving a CT scan within 24 hours included sex (male; adjusted relative risk [aRR], 1.18; 95% CI, 1.04-1.33), hospitalized at a children's hospital (aRR, 1.80; 95% CI, 1.32-2.45), consulted by both ophthalmology and otolaryngology (aRR, 3.12; 95% CI, 2.35-4.13) or either ophthalmology (aRR, 2.19; 95% CI, 1.66-2.90) or otolaryngology (aRR, 2.66; 95% CI, 1.84-3.86), and had proptosis (aRR, 1.39; 95% CI, 1.24-1.57) or eye swollen shut (aRR, 1.27; 95% CI, 1.13-1.43) as clinical signs upon ED presentation. Children aged younger than 5years were less likely to receive early CT imaging (aRR, 0.63; 95% CI, 0.53-0.74). There were no associations between time of ED triage, temperature greater than 38 °C, or inflammatory markers with early CT imaging. Although several patient and hospital factors associated with early CT imaging decisions in children with severe orbital infections are associated with more severe infections, newly identified risk factors, such as inflammatory markers, were not. These findings will help better the understanding of clinical management and indications for CT imaging.

The Neutrophil-Lymphocyte Ratio in Pediatric Preseptal and Orbital Infectious Cellulitis.

The neutrophil-lymphocyte ratio (NLR) is an important biomarker in a variety of systemic conditions, though its role in orbital disease remains unclear. We sought to investigate the utility of the NLR in distinguishing orbital cellulitis (OC) from preseptal cellulitis (PC) in a pediatric population. The earliest available NLRs of immunocompetent pediatric patients who presented to the emergency department with OC and PC were calculated from a single institution's database. Demographic and interventional data related to each encounter were also gathered. NLRs were compared via the Mann-Whitney test between OC and PC cases. Among patients with OC, the relationship between presenting NLR and requirement for surgical intervention and between presenting NLR and subperiosteal abscess was similarly examined. All statistical analyses were performed in GraphPad Prism 9 (Insight Partners, New York, NY, U.S.A.). Forty-three encounters of patients with OC and 23 encounters of patients with PC were identified. Median presenting NLR for the OC group was 4.18 (standard deviation: 5.44), whereas for the PC group, it was 1.96 (standard deviation: 2.38), representing a significant difference between the 2 groups (p < 0.001). The 26 patients with OC who required surgical intervention had significantly greater presenting NLR (median NLR: 6.53, standard deviation: 6.29) as compared to the 17 patients with OC who were managed medically (median NLR: 3.09, standard deviation: 2.37, p = 0.003). There was no statistically significant difference between 34 patients with OC who had a subperiosteal abscess (median NLR: 4.40, standard deviation: 5.91) and the 9 patients with OC who did not (median NLR: 3.84, standard deviation: 2.37, p = 0.401). An elevated NLR is a useful adjunct to the clinical examination in discerning OC from PC or in risk stratification for patients with OC who may need surgical treatment of their periocular infectious disease. In select cases, a reassuring NLR may allow the cost and radiation exposure associated with radiographic assessment to be avoided.

Identifying opportunities to reduce imaging overuse in hospitalized children.

Radiologic imaging is routinely performed to aid in diagnosis for hospitalized children. Identifying and reducing variability in imaging practices can improve care while reducing harms and costs. To identify common inpatient pediatric conditions with high prevalence of imaging and variation in imaging practices and imaging-related costs across hospitals. We conducted a cross-sectional study of children 0-18 years old admitted to 50 children's hospitals in the Pediatric Health Information Systems database between 2017 and 2019. We excluded patients with complex chronic conditions, pregnancy, newborn, or neonatal intensive care charges, and those who died or who were discharged to hospice or rehabilitation facilities. Conditions with at least 2500 discharges and in which ≥30% of patients received imaging were included. Outcomes included imaging frequency, standardized imaging-related costs (including all modalities across all encounters), and hospital-level variation in imaging costs using the intraclass correlation coefficient (ICC). Of the 56 included conditions, imaging was most frequently conducted in patients with pectus excavatum (97.8%), scoliosis (96.2%), and intestinal obstruction (96%). Fracture ($21.4 million), trauma ($15.7 million), and appendicitis ($8.6 million) had the highest total imaging-related costs. Conditions with the highest geometric mean standardized imaging costs were nervous system disorders ($507), osteomyelitis ($494), vesicoureteral reflux/hydronephrosis ($468). Scoliosis (ICC = 0.49) and preseptal cellulitis (ICC = 0.48) had the highest variation in imaging-related costs. To reduce imaging overuse in hospitalized children, conditions with frequent imaging, high imaging-related costs, and high hospital-level variation in imaging practices should serve as priorities for future evidence generation, guideline development, and/or improvement initiatives.

Diagnosis and treatment of periorbital and orbital cellulitis in children.

Diagnosis and treatment of periorbital and orbital cellulitis in children.

Dog Bites With Resultant Periorbital Cellulitis.

This case study examines the delayed presentation of a facial dog bite, an uncommon occurrence in the periorbital area. Initially perceived as a minor injury, the wound was disregarded in its early stages. However, as the infection progressed, prompting urgent evaluation in the emergency department (ED) as the severity became evident. The patient was diagnosed with an acute facial infection carrying the potential for periorbital cellulitis and abscess formation, necessitating immediate imaging. Prompt evaluation of penetrating animal bites, particularly dog bites, is crucial due to their high infection risk. As emphasized by Hamed-Assam et al., immediate attention and prophylactic antibiotics are advised for such cases, preferably broad-spectrum antibiotics with anaerobic coverage. The patient underwent treatment in the ED approximately a day after the incident, receiving antibiotics and subsequently discharged following advanced diagnostic imaging. This case underscores the importance of recognizing and promptly addressing delayed dog bites, emphasizing the significance of immediate medical intervention post-penetrating animal bites.

Impact of the COVID-19 Pandemic on Microbial Profiles and Clinical Outcomes in Orbital and Preseptal Cellulitis.

Orbital cellulitis and severe preseptal cellulitis are critical periocular infections with potential vision- and life-threatening implications. The COVID-19 pandemic is hypothesized to have had an influence on their presentation and pathogenesis; however, the real impact remains unclear. In this retrospective multicenter cohort study from January 2017 to December 2022, we analyzed 1285 cases with preseptal or orbital cellulitis in pre-pandemic (2017-2019) and pandemic (2020-2022) cohorts. A notable decrease in hospitalized cases during the pandemic period was observed (97 patients in the pre-pandemic group vs. 54 in the pandemic group, p = 0.004), particularly among individuals aged 30-39 (p = 0.028). Sinusitis remained the leading cause, but odontogenic cases increased (p = 0.025). In addition, microbial diversity decreased during the pandemic, with the effective number of species decreasing from 17.07 to 8.87, accompanied by a rise in antibiotic resistance, notably against erythromycin, oxacillin, penicillin, and metronidazole. While visual outcomes appeared worse in the pandemic group, statistical significance was not reached. These findings suggest that the characteristics, etiology, microbial profiles, resistance patterns, and visual outcomes of orbital and preseptal cellulitis have undergone alterations post-COVID-19 pandemic. Vigilance in clinical management and public health measures is crucial, with further research needed to optimize treatment strategies.

Evaluation of Clinical and Laboratory Findings of Sinusitis Complications in Children

Abstract Objective This retrospective study evaluates the demographic characteristics, clinical symptoms, laboratory results, treatment approaches, and outcomes of children with complications arising from bacterial sinusitis. Methods Fifty-four pediatric inpatients with sinusitis complications admitted between September 2013 and October 2022 were included in the study. These patients were categorized into two groups: those with preseptal cellulitis (group 1) and those with orbital–intracranial complications (group 2). Results The median age of the patients was 10.8 years, and 61.1% were males. Maxillary sinusitis (n = 40.74%) was the most common type of sinus involvement. Half of the patients exhibited preseptal cellulitis. The median age of our patients with intracranial complications was 13.7 years, while the median age of patients with orbital complications was 8 years. The predominant orbital–intracranial complication was meningitis, which accounted for 41% of the cases. All patients with a subdural abscess (n = 6) presented with frontal sinusitis, while all cases of cavernous sinus thrombosis (n = 3) involved the sphenoidal sinus. Surgical intervention was undertaken in 37% of cases. Streptococcus pneumoniae was the most frequently isolated microorganism. The median duration of hospital stay was 14 days, with a total median treatment duration of 21 days. There were no fatalities, although neurological sequelae were observed in 7.4% of patients (n = 4). Conclusion Preseptal cellulitis and meningitis remain the most common complications of sinusitis in children. Adolescents with sinusitis should be monitored closely for intracranial complications. The prevalence of S. pneumoniae as the most frequently detected pathogen underscores the importance of vaccination.

Transorbital Endoscopic Approach for Managing Challenging Frontal Sinus Lesions: Results and Operative Technique Description

Abstract Objective The aim of this study was to describe our experience using the transorbital endoscopic approach (TEA) in the frontal sinus and the step-by-step technique used. Materials and Methods We reviewed the charts from adult patients who underwent management of frontal sinus lesions with TEA performed from 2017 to 2022. Results Seven patients underwent eight surgeries for frontal sinus lesions using TEA in combination with the endoscopic transnasal approach (ETA), with the majority on the left side (5/8, 62.5%). The average age was 53.9 years, with six male patients and one female patient. Gross total resection (GTR) was achieved in all cases. The most common symptoms leading to surgery were headaches or a sensation of pressure in the forehead (5/8, 62.5%), followed by a decreased sense of smell (3/8, 37.5%), diplopia (3/8, 37.5%), proptosis (2/8, 20%), periorbital cellulitis (2/8, 20%), and decreased visual acuity (1/8, 12.5%). The most common etiology in this case series was mucocele (5/8, 62.5%), followed by osteoid osteoma (2/8, 20%), and inverted papilloma (1/8, 12.5%). The length of stay in all cases was 1 day. The most common complication was mild and transitory V1 numbness, which fully recovered after 6 months (5/8, 62.5%). The average follow-up period was 24.6 months (range of 3–48 months). Conclusion Transoral Endoscopic Approach (TEA) demonstrated being a valuable complement to ETA approaches for treating frontal sinus lesions, especially in challenging regions. The transorbital approach is feasible and can safely achieve GTR for a variety of pathologies while effectively controlling symptoms and resulting in a 1-day hospital stay.

Case Report of Benign Diffuse Anterior Scleritis Associated with SARS-CoV-2

COVID-19 is an emerging infectious disease classified as a zoonotic illness caused by the SARS-CoV-2 strain of coronavirus. This enveloped, positive-sense, non-segmented RNA virus belongs to the order Nidovirales and the family Coronaviridae. Its primary mode of transmission is human-to-human through respiratory droplets. Ophthalmologists worldwide have reported various ocular manifestations associated with the infection. Recent studies have shown that SARS-CoV-2 binds to the cellular receptor for angiotensin-converting enzyme 2 (ACE2) and interacts with the transmembrane serine protease 2 (TMPRSS2), both of which are known to be expressed in the human cornea, retina, and conjunctival epithelium [1, 2]. The aim of this work is to present a case of a patient who developed diffuse viral scleritis related to COVID-19, detailing the diagnostic and therapeutic approaches as well as the patient's progression. We report the case of a 63-year-old man with a history of high triglycerides who developed flu-like symptoms and severe tiredness for over a week. A COVID-19 test came back positive. Ten days later, he had a painful, red right eye but no change in vision. An eye exam showed some redness in the conjunctiva, a clear cornea, and normal pressure in the eye. The fellow eye looked normal as well. He was treated with topical steroids and artificial tears, which helped initially. However, after finishing treatment, his symptoms worsened with more redness and pain, and now both eyes were affected. Further examination of the right eye showed swelling of the eyelid (preseptal cellulitis) and widespread redness in the conjunctiva. The Neosynephrine test was negative, and there was pain when moving the eye. The cornea was clear but had some superficial punctate keratitis, and the anterior chamber looked normal. The left eye also showed redness but was otherwise normal. A full lab workup (including blood tests and serologies for HSV1-2) came back normal. Considering his previous C

Evaluation of moderate periorbital cellulitis and home-based therapy in children (EPOCH study, Part 2): A prospective single centre cohort study.

Paediatric periorbital cellulitis, a common eye condition, typically requires inpatient admission for intravenous antibiotics due to concerns about orbital spread. This study aimed to assess the safety and effectiveness of ambulatory management for children with moderate periorbital cellulitis. Over a 24-month period, we prospectively enrolled 84 children aged 1 to 16 years who presented with moderate periorbital cellulitis to the emergency department. Demographic and clinical data were collected. Following a guideline-based decision tree, eligible children received intravenous antibiotics and were discharged with a peripheral cannula for follow-up in ambulatory care and ophthalmology clinics. Descriptive statistics were used for data presentation. Among the 84 children, 62 (73.8%) were managed through the ambulatory care model. Within the category of moderate POC, those who were admitted to the hospital did not have higher CRP or White Cell counts and received IV antibiotics for the same length of time. The ambulatory care clinic provided a total of 132 daily doses of intravenous antibiotics. Two children treated on this pathway required inpatient admission due to clinical deterioration, one of whom required ophthalmic surgical intervention. There was no mortality or sight-threatening complications in this study. Implementing a directed ambulatory care pathway for children with moderate periorbital cellulitis proved to be an effective and safe management strategy. This approach reduces the strain on hospital bed occupancy while promoting community-based patient care.

A NOVEL TREATMENT FOR PTOSIS COMPLICATION AFTER PRESEPTAL CELLULITIS IN DIABETIC PATIENT (CASE REPORT

Background: Preseptal cellulitis (PC) is an inflammation of the eyelid and surrounding soft tissues covering the anterior portion of the orbital septum (palpebral fascia) characterized by eyelids unilateral swelling, can develop to orbital cellulitis and be fatal for diabetics after complication. Two main mechanisms of the PC development are distinguished. One of them is based on a spread of local infection on the eyelid. The second group of PC causes include eye surgery, trauma or insect bites. In most cases, serious complications are rare, but sometimes sight-threatening infections behind the orbital septum may develop. It is important to be able to distinguish periorbital cellulitis from orbital cellulitis, and treat according to the diagnosis. In this paper, we discuss a case of PC and successful recovery after medical intervention even though due to late presentation to the Clinic, patient developed ptosis. A clinical case of PC developed to complete ptosis, treatment and successful elimination of all residual symptoms in diabetic patient with is described. We used a novel approach to PC treatment and ptosis after PC. Results: We achieved complete recovery from ptosis after PS in a diabetic patient thanks to novel approach to treatment Findings: 1. The use of nepafenac instead of diclofenac helps to enhance the effectiveness of treatment and prevent the spread of infection to nearby tissues during PС. 2. For the treatment PC complication, ptosis, we suggest the simultaneous, not separated in time use of proserin in combination with glycine.

A Case of Orbital Abscess Caused by Prevotella baroniae Infection

Purpose: We report a case in which &lt;i&gt;Prevotella baroniae&lt;/i&gt;, an oral pathogen, was transmitted to the orbit, leading to the development of orbital abscess.Case summary: A 56-year-old female presented with persistent ocular pain, eye movement limitation, periorbital swelling and erythema on the left eyelid. The patient had a history of aplastic anemia and had undergone sequestrectomy surgery for maxillary osteomyelitis and exposed sinus bone on the left side of the face in the past. Orbit magnetic resonance imaging revealed irregular enhancement and disruption of the left orbital floor, indicative of cellulitis. The patient was thus diagnosed with periorbital cellulitis and orbital abscess. Debridement was performed, and purulent discharge was observed and a culture was performed. The culture identified &lt;i&gt;P. baroniae&lt;/i&gt;, suggesting a spread of infection from oral, dontogenic infection to the orbit. The patient showed improvement after intensive antibiotic treatment.Conclusions: Orbital abscesses should be treated with appropriate necrotic tissue debridement, drainage, and intensive and effective antibiotics. This is the first report of an orbital abscess caused by orbital transmission of &lt;i&gt;P. baronii&lt;/i&gt;, an oral infection, in Korea.

Improving Antibiotic Use in Pediatric Preseptal Cellulitis Using a Clinical Practice Guideline.

The purpose of this study was to evaluate the impact of a clinical practice guideline (CPG) on antibiotic use and resource utilization for pediatric preseptal cellulitis. This retrospective quasiexperimental study included patients between the age of 2 months and 17 years admitted for preseptal cellulitis between January 2013 and December 2023. The preseptal cellulitis CPG was implemented in December 2020 using a multifaceted strategy that included buy-in from key stakeholders, education of frontline providers, the official CPG launch, and stakeholder check-ins. The primary outcome was the use of broad-spectrum antibiotics, including dual/triple therapy and methicillin-resistant Staphylococcus aureus (MRSA) active antibiotics. The secondary outcome was resource utilization including blood testing and imaging. Outcomes were compared pre- and post-CPG implementation using the Fisher exact test and logistic regressions. Of 236 patients meeting inclusion criteria, 175 and 61 patients composed the pre- and post-CPG cohorts, respectively. Median age (interquartile range) was 4.0 (1.8-8.3) years and 46% of the population were female. Post-CPG implementation changes in empirical antibiotic use included decreases in broad-spectrum use from 100% to 66% (P < .001), dual/triple therapy from 47% to 16% (P < .001), and MRSA active agents from 86% to 26% (P < .001). There was a decrease in complete blood count and blood culture orders from 75% to 57% (P = .014) and 32% to 18% (P = .047), respectively. Use of broad-spectrum antibiotics, including dual/triple therapy and MRSA active antibiotics for the treatment of pediatric preseptal cellulitis, decreased after CPG implementation.

Differentiation of bacterial orbital cellulitis and diffuse non-specific orbital inflammation on magnetic resonance imaging.

To examine the radiological differences between bacterial orbital cellulitis (OC) and diffuse non-specific orbital inflammation (DNSOI) on magnetic resonance imaging (MRI). Retrospective study of patients with OC and DNSOI with an MRI orbital scan. Localised orbital inflammation (e.g., idiopathic dacryoadenitis and myositis), quiescent orbital inflammation and pre-septal cellulitis were excluded. Thirty-two patients presenting between 2008 and 2023, including twenty-one OC patients (mean age: 42.5 ± 24.9 years old, male: 6), and eleven DNSOI patients (mean age: 52.3 ± 17.8 years old, male: 16). Both OC and DNSOI demonstrate orbital fat contrast-enhancement. However, whilst OC demonstrated a hyperintense T2 signal (P < 0.001), variable signal was observed in DNSOI, with a hypointense T2 signal more suggestive of DNSOI (P = 0.012). When the lacrimal glands were involved, indistinct margins were more likely in OC (P < 0.001), whilst gross enlargement and contrast-enhancement was observed in DNSOI (P = 0.032 and 0.017, respectively). Peripheral contrast-enhancement of the extraocular muscle (EOM) (P = 0.002) was more common in OC, whilst DNSOI demonstrated variable contrast-enhancement throughout the affected EOM (P < 0.001). The presence of contralateral abnormalities, such as lacrimal gland enlargement and EOM involvement, are more suggestive of DNSOI. Several MRI features, beyond overt sinogenic disease, may help to differentiate OC from DNSOI, including the orbital fat signal intensity, EOM and/or lacrimal gland involvement, and contralateral orbital abnormalities. However, these features may not be specific, and thus highlights the ongoing radiological dilemma clinicians are faced when tasked with differentiating between infectious and non-infectious orbital inflammatory disease.

Pre-septal and Orbital Cellulitis: A Retrospective Analysis of Manifestations and Outcomes of a Tertiary Center in Kuwait.

Introduction Orbital cellulitis is an infectious condition that presents a gap in the literature in regard to its manifestations in the Middle East. A retrospective investigation was undertaken at one tertiary care facility in Kuwait, aiming to augment regional insights into the etiological factors and subsequent outcomes associated with this condition. Methods A retrospective review collected data from 92 patients in a tertiary care center in Kuwait for patients admitted with pre-septal and orbital cellulitis between January 2013 and June 2023. Primary outcomes assessed the resolution of symptoms, categorized as "completely resolved" and "resolved with complications". Secondary outcome measures included patients' ages, microbiology, laboratory, and radiological findings. Gender, predisposing conditions, surgical status, and orbital involvement were additionally extracted and analyzed descriptively. Results Data of n=92 (56 males and 36 females) were extracted. Ages ranged from 20 days to 18 years, the mean being seven years. Additionally, 52.2% (n=48) were diagnosed with orbital cellulitis, and 42.4% (n=39) were diagnosed with pre-septal cellulitis on admission. Cultures were available for n=60. Specifically, 52.1% (n=48) received CT scans; 6.5% (n=6) MRI scans; and 98.9% (n=91) received antibiotics (microbiology investigated: n=83). Ceftriaxone was used in 82.6% (n=76); 20.6% (n=19) received surgical interventions, and incision and drainage (I&D) were done on 15.2% (n=14). Visual acuity was assessed in 59.7% (n=55) patients. Five (5.43%) reported visual deterioration, and 87 (94.6%) of the outcomes were classified as "completely resolved". Conclusion Upper respiratory tract infections were the most common documented predisposing risk factor in the development of pre-septal and orbital cellulitis. Adverse outcomes in vision were documented in 5.43% of patients. A paucity of regional data highlights the importance of conducting further studies locally.
