Pinkeye is a highly contagious disease of goats with different aetiologies. Surveys in Lao PDR have identified eye lesions typical of pinkeye as a common condition, however, this has not been confirmed diagnostically, and the responsible pathogens have not been identified. A matched case-control study was implemented in 70 goat holdings from Savannakhet province, Lao PDR, to detect agents causing pinkeye and conduct phylogenetic analysis of the identified pathogens. Fifty eye swabs from goats with infected eyes (cases) and 50 paired samples from unaffected cohorts (controls) were collected from 25 holdings. Samples were tested using quantitative PCR assays targeting known pinkeye pathogens at the genus and species levels. The prevalence of pathogens in case and control goats was as follows: Mycoplasma conjunctivae (94% and 74% respectively, P = 0.006, OR = 5.5), Chlamydia pecorum (4%, 10%), Moraxella ovis (30%, 30%), Moraxella bovis (0%, 0%) and Moraxella bovoculi (0%, 0%). M. conjunctivae was present in a high proportion of goats in both groups revealing that Lao goats are carriers of M. conjunctivae. However, the mean log10 genome copy number/µL of DNA extract was significantly higher in case goats than control goats (P < 0.05). Thus, M. conjunctivae is likely the principal causative agent of pinkeye in Lao goats with carrier status converting to clinical infection following corneal damage or other causative factors. M. conjunctivae detected in samples from different goats and districts showed low genetic diversity. Identifying the causes of pinkeye in Lao goats will assist in designing appropriate treatment and control strategies.

BACKGROUND: This study investigates the incidence of ocular involvement in Kawasaki disease (KD) and evaluates the relationship between ocular manifestations, laboratory findings, echocardiographic findings, and intravenous immunoglobulin (IVIG) resistance. METHODS: We conducted a cross-sectional study with 58 KD patients from June 2021 to March 2023. For all patients, a complete ophthalmologic examination and echocardiography were performed in the acute phase before starting the treatment. We analyzed the age, sex, mean of white blood cell (WBC) count, platelet count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), echocardiographic findings and IVIG responses for all patients and compared the group with ocular involvement with the group without involvement. RESULTS: The incidence of bilateral acute conjunctivitis was 70.7%, while that of acute uveitis was 30%. Patients with uveitis had significantly higher rates of Coronary artery dilatation and IVIG resistance, as well as higher mean levels of WBC, platelet, and CRP compared to those without uveitis. (P < 0.05). Additionally, the age of patients with uveitis involvement was lower than those without involvement. No significant relationships existed between ESR, AST, or ALT values and uveitis (P > 0.05). Furthermore, no significant correlations existed between any examined items and acute bilateral conjunctivitis. CONCLUSION: Uveitis in KD is significantly associated with coronary artery dilatation, IVIG resistance, higher WBC count, platelet count, and CRP level.

Introduction: Conjunctivitis is a highly prevalent ocular disease that flares up every year. The humidity and high temperature favour the causative agents responsible for the epidemic. Acute infective conjunctivitis may be either viral or bacterial, a distinct type of condition with unique clinical features and treatment approaches. The aim of the study was to find out the prevalence of acute conjunctivitis among patients visiting the outpatient Department of Ophthalmology in a tertiary care centre. Methods: This descriptive cross-sectional study was conducted among the patients visiting the outpatient Department of Ophthalmology. Data of 30 August 2023 to 30 September 2023 was collected between 21 November 2023 to 24 November 2023. All patients presenting in the Ophthalmology Department having complete hospital record were included in the study. Patients having missing data on the medical records of the hospital were excluded. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 5,507 patients, acute conjunctivitis was seen in 1240 (22.52%) (21.42-23.62, 95% Confidence Interval). The majority were male 732 (59.03%) and adults 760 (61.29%) with a mean age of 32.56±18.74 years. Conclusions: The prevalence of conjunctivitis among patients visiting the outpatient Department of Opthalmology was found to be higher than other studies done in similar settings. Keywords: conjunctivitis; disease outbreaks; enterovirus.

PURPOSE: To report the clinical signs, symptoms, and viral clearance in individuals in the United States with adenoviral conjunctivitis (Ad-Cs). METHODS: Individuals ≥ 18 years presenting within 4 days of symptoms of Ad-Cs who met eligibility criteria and tested positive with both point-of-care immunoassay antigen and quantitative polymerase chain reaction (qPCR) testing were enrolled. Patient-reported symptoms, clinician-graded signs, and qPCR viral titers were collected at baseline, days 1-2, 4 (days 3-5), 7 (days 6-10), 14 (days 11-17) and 21 (days 18-21). RESULTS: There was no detectable viral titers by the day 14 visit in 6/8 patients. By day 21, there was no detectable viral titers in the 7 participants who completed the visit; however, signs and symptoms persisted including: blurry vision (5/7), discomfort (2/7) or redness (1/7). Masked clinicians also noted conjunctival redness (4/7), follicular conjunctivitis (4/7) and bulbar edema (3/7). CONCLUSION: Many patient-reported symptoms and clinical signs persist after viral titers are no longer detectable by qPCR. Using clinical signs and symptoms to determine quarantine duration may result in patients being furloughed longer than the time that the patient is infectious.

PURPOSE: To evaluate the incidence and risk factors for inflammatory conditions among patients with primary acquired nasolacrimal duct obstruction (PANDO). METHODS: A retrospective case-control study was conducted among patients of Clalit Health Services (CHS) in Israel from 2001 to 2022. For each case, three controls were matched among all CHS patients according to year of birth, sex, and ethnicity. Differences in demographic characteristics, ocular surface, eyelid, upper airway, and systemic diseases were assessed between the groups, and odds ratios (OR) were calculated. RESULTS: A total of 60,726 patients diagnosed with PANDO were included. The average age of PANDO patients was 63 ± 18 years, 63% were female. Significant associations were found between PANDO and various ocular surface and eyelid conditions, including chronic conjunctivitis (OR 2.96, 95% CI [2.73-3.20]), vernal keratoconjunctivitis (OR 2.89, 95% CI [2.45-3.29]), and blepharitis (OR 2.75, 95% CI [2.68-2.83]). There was a significant association with various upper airway conditions, including rhinitis (OR 1.62, 95% CI [1.58-1.66]), chronic sinusitis (OR 1.71, 95% CI [1.62-1.80]), and deviated nasal septum (OR 1.76, 95% CI [1.69-1.84]). Association was also observed with systemic conditions, including asthma (OR 1.34, 95% CI [1.27-1.41]) and atopic dermatitis (OR 1.36, 95% CI [1.32-1.41]). CONCLUSION: Ocular surface, eyelid, upper airway, and systemic inflammatory-related diseases were found to be associated with PANDO, supporting the theory that inflammation has a prominent role in the pathophysiology of PANDO.

PURPOSE: To explore the clinical features of COVID-19-associated conjunctivitis with the objective of preventing the spread of infection. STUDY DESIGN: Retrospective cohort study. METHODS: From March 2020 to March 2021, we retrospectively reviewed 26 (9.8%) consecutive COVID-19 patients with conjunctivitis among 282 COVID-19 cases admitted to our hospital. Clinical symptoms, onset date of conjunctivitis, time to patient recovery, and eye drop intervention were investigated. In addition, risk factors for developing conjunctivitis were statistically examined among 206 inpatients available for within 5 days of the onset. A multivariate analysis of conjunctivitis risk factors was performed. RESULTS: Among the 282 COVID-19 patients, 4 (1.4%) had conjunctival hyperemia as the primary symptom. The median time of onset was 4 days after the COVID-19 onset. Hyperemia was observed in all cases, but other ocular symptoms were rare. The median duration of hyperemia was 3 days. A multiple logistic regression analysis revealed that a young age (p=0.005) and current smoking habit (p=0.027) were independent risk factors for conjunctivitis after COVID-19. CONCLUSIONS: COVID-19-associated conjunctivitis is rare in the elderly and strongly associated with a history of smoking. It often occurs in the early stages of infection, and while hyperemia is recognized as a clinical symptom, other ocular symptoms are rare or non-existent. Many cases recover within a short time.

The COVID-19 pandemic notably influenced the transmission of infectious diseases across various age groups. In this study, we assessed its impact on pediatric acute conjunctivitis trends in southern Israel. We analyzed acute conjunctivitis diagnoses from 2017 to 2022, categorizing them into pre-lockdown, lockdown, and post-lockdown intervals. A control group of non-infectious dermatologic conditions was included. Time-series analysis, adjusted for seasonality, was employed. Pre-lockdown data indicated steady conjunctivitis diagnoses, primarily in winter. Post-lockdown interval exhibited an added summer peak before the regular winter surge. The lockdown saw a 56% decline in diagnoses, most pronounced in younger ages. Post-lockdown observed a 7% overall drop with age-specific variations. The acute conjunctivitis IRR was 0.44 (95% CI 0.39-0.49) during lockdowns and 0.93 (95% CI 0.86-1.02) post-lockdowns. Control group IRRs were 0.84 (95% CI 0.78-0.89) and 0.90 (95% CI 0.84-0.96), respectively, with the 0-5 age range demonstrating significant disparities. Pediatric acute conjunctivitis in southern Israel decreased significantly during the pandemic. Post-lockdown patterns varied by age group. An unusual summer peak in cases was observed post-lockdown; this peak may be influenced by a combination of altered behaviors in the summer and possibly increased susceptibility to infection.

INTRODUCTION: The time trends of the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy previously described in the ISAAC (International Study of Asthma and Allergies in Childhood) in 2002 are unknown; or if the geographical or age differences in Spain persist. OBJECTIVE: To describe the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy in different Spanish geographical areas and compare them with those of the ISAAC. METHODS: Cross-sectional study of the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy, carried out in 2016-2019 on 19943 adolescents aged 13-14 years and 17215 schoolchildren aged 6-7 years from six Spanish areas (Cartagena, Bilbao, Cantabria, La Coruña, Pamplona, and Salamanca), through a questionnaire based on the Global Asthma Network (GAN) protocol. RESULTS: The prevalences of recent rhinitis and rhinoconjunctivitis (last 12 months), and nasal allergy/hay fever were 35.1%, 17.6%, and 14.6% in the adolescents and 20%, 8.5%, and 8.9% in the schoolchildren, respectively, with rhinoconjunctivitis in adolescents varying from 20.9% in Bilbao to 13.4% in Cartagena; and in schoolchildren, from 9.8% in La Coruña to 6.4% in Pamplona. These prevalences of rhinoconjunctivitis and nasal allergy in adolescents were higher than those described in the ISAAC (16.3% and 13%) and similar in schoolchildren to the ISAAC (9% and 9.4%). CONCLUSIONS: There has been a stabilisation of rhinitis, rhinoconjunctivitis and nasal allergy in schoolchildren that slows the previous upward trend of ISAAC; and a slight non-significant increase in rhinoconjunctivitis and nasal allergy in adolescents. The variability found in adolescents would require local research to be better understood.

INTRODUCTION: Epidemiological data on the use of eye-related emergency services by children are limited. The objective of this study was to determine how COVID-19 affected the epidemiological trends of pediatric ocular emergencies. METHODS: We performed a retrospective chart review of children under the age of 18 years who visited our eye-related emergency department between March 17 and June 7, 2020 and between March 18 and June 9, 2019. This was a descriptive and comparative analysis of the two study periods based on the demographic characteristics of patients and the diagnosis reported by the ophthalmologist in the digital medical charts. One of the investigators performed a second reading of the files to homogenize the diagnosis classification based on the most frequently found items. RESULTS: In total, 754 children were seen in our eye-related emergency department during the 2020 study period versus 1399 in 2019, representing a 46% decrease. In 2019, the four main diagnoses were traumatic injury (30%), allergic conjunctivitis (15%), infectious conjunctivitis (12%), and chalazion/blepharitis (12%). In the 2020 study period there was a significant decrease in the proportion of patients presenting with traumatic injuries (p < 0.001), infectious conjunctivitis (p = 0.03), and chalazion/blepharitis (p < 0.001). Consultations for chalazion/blepharitis were the most affected by the pandemic, followed by traumatic injuries (-72% and -64%, respectively). The proportion of patients who required surgery after trauma was higher in 2020 than in 2019 (p < 0.01), but the absolute number of severe trauma cases remained stable. CONCLUSIONS: The COVID-19 pandemic was accompanied by a decrease in the overall use of a pediatric eye-related emergency services in Paris. Visits due to benign causes and ocular trauma also decreased, but visits for more severe pathologies were not affected. Longer-term epidemiological studies may confirm or refute a change in eye emergency department use habits.

Following the "hygiene hypothesis" and the increase in the prevalence of atopic diseases such as allergic rhinitis, a plethora of studies have investigated the role of sibship composition as a protective factor, but findings are conflicting. The aim of this study was to synthesize the global literature linking birth order and sibship size (number of siblings) to the risk of allergic rhinitis. Fifteen databases were systematically searched, with no restrictions on publication date or language. Observational studies with defined sibship composition (birth order or sibship size) as exposure and allergic rhinitis or allergic rhinoconjunctivitis (self-reported or clinically diagnosed) as outcome were eligible. Study selection, data extraction, and quality assessment were performed independently in pairs. Relevant data were summarized in tables. Comparable numerical data were analyzed using meta-analysis with robust variance estimation (RVE). Seventy-six reports with >2 million subjects were identified. Being second- or later-born child was associated with protection against both current (pooled risk ratio [RR] 0.79, 95% CI 0.73-0.86) and ever (RR 0.77, 95% CI 0.68-0.88) allergic rhinitis. Having siblings, regardless of birth order, was associated with a decreased risk of current allergic rhinitis (RR 0.89, 95% CI 0.83-0.95) and allergic rhinoconjunctivitis (RR 0.92, 95% CI 0.86-0.98). These effects were unchanged across age, time period, and geographical regions. Our findings thus indicate that primarily, a higher birth order, and to a lesser extent the number of siblings, is associated with a lower risk of developing allergic rhinitis.

BACKGROUND: Adenovirus (ADV) outbreaks in neonatal intensive care units (NICU) can lead to durable transmission and serious adverse outcomes. This study describes the investigation and control of an ADV-D8 outbreak in an NICU, associated with ophthalmologic equipment used during retinopathy of prematurity (ROP) screening. Cases were observed in neonates, parents and nurses. METHODS: The outbreak investigation was performed including sampling patients, parents and health care workers as well as the environment for molecular detection of ADV DNA. The investigation was also conducted in the guest house where some parents were temporary residents. A retrospective cohort study focused on neonates hospitalized during the epidemic period to assess the risk associated with ROP examination. RESULTS: Fifteen cases were identified in neonates; all but one presented with conjunctivitis. Two healthcare workers and 18 parents acquired conjunctivitis. ADV DNA was identified on the RetCam and on the freezer shared by parents. All ADV-positive samples were typed as ADV-D8. ADV infections occurred more frequently in neonates who had ROP examinations (37.8% (14/37) vs (0.9% (1/110); P<0.001) (relative risk 41.6; (5.7-305.8)). The RetCam was disinfected between two examinations using a disinfectant that was virucidal on ADV after a 30-min contact. CONCLUSION: This outbreak was significantly associated with ROP examination with a RetCam that had a disinfection protocol ill-adapted to rapid patient turnover. In addition, nosocomial transmission via the parents to neonates and parent-to-parent transmission is likely to have played a role in the dissemination of cases. No further cases were observed after the new disinfection procedure was enforced.

As one of the most common eye conditions being presented at clinics, acute conjunctivitis puts substantial strain on primary health resources. To reduce this public health burden, it is important to forecast and provide forward guidance to policymakers by estimating conjunctivitis trends, taking into account factors which influence transmission. Using a high-dimensional set of ambient air pollution and meteorological data, this study describes new approaches to point and probabilistic forecasting of conjunctivitis burden which can be readily translated to other infectious diseases. Over the period of 2012 - 2022, we show that simple models without environmental data provided better point forecasts but the more complex models which optimized predictive accuracy and combined multiple predictors demonstrated superior density forecast performance. These results were shown to be consistent over periods with and without structural breaks in transmission. Furthermore, ecological analysis using post-selection inference showed that increases in SO2, O3 surface concentration and total precipitation were associated to increased conjunctivitis attendance. The methods proposed can provide rich and informative forward guidance for outbreak preparedness and help guide healthcare resource planning in both stable periods of transmission and periods where structural breaks in data occur.

PURPOSE: The purpose of this study was to pool the prevalence rate of monkeypox-associated eye manifestations and/or complications during the current and previous outbreaks. DESIGN: A systematic review and meta-analysis. MATERIALS AND METHODS: On August 7, 2022, PubMed, Scopus, Web of Science, EMBASE, and Google Scholar were searched for relevant articles. We included all studies that reported the involvement of the eye (either as a manifestation or a complication) among patients with monkeypox. The primary outcome included pooling the effect size (ES) of reported manifestations and complications, and the secondary outcome included the conduct of a subgroup analysis based on the timing of the monkeypox outbreak (before vs. during 2022). RESULTS: Eleven studies reporting 3179 monkeypox-confirmed cases were included. Eye manifestations included conjunctivitis, corneal, conjunctival, and eyelid lesions, photophobia, and eye pain. Compared with previous monkeypox outbreaks, the current outbreak revealed much lower rates of ocular involvement in terms of conjunctivitis (ES=1%; 95% CI: 0%-1% vs. ES=17%; 95% CI: 11%-22%), corneal and conjunctival lesions (ES=1%; 95% CI: 0%-2% vs. ES=13%; 95% CI: 4%-22%), and eyelid lesions (ES=1%; 95% CI: 0%-4% vs. ES=13%; 95% CI: 5%-28%). Monkeypox-associated eye complications were reported only in the previous outbreaks which included keratitis (ES=4%; 95% CI: 3%-6%), corneal ulceration (ES=4%; 95% CI: 2%-5%), unilateral (ES=3%; 95% CI: 1%-4%) and bilateral blindness (ES=0%; 95% CI: 0%-2%), and impaired vision (ES=4%; 95% CI: 1%-8%). CONCLUSIONS: Ophthalmic manifestations and complications are common among monkeypox-confirmed cases. Although these data are mainly related to previous outbreaks, health care workers should familiarize themselves with these signs to provide better care for monkeypox patients.

BACKGROUND: Although ocular adverse events are frequent in AD patients treated with dupilumab, their characterization remains limited due to a lack of prospective studies with a systematic ophthalmological examination. OBJECTIVE: To examine the incidence, characteristics and risk factors of dupilumab-induced ocular adverse events. METHODS: A prospective, multicenter, and real-life study in adult AD patients treated with dupilumab. RESULTS: At baseline, 27 out of 181 patients (14.9%) had conjunctivitis. At week 16 (W16), 25 out of 27 had improved their conjunctivitis and 2 remained stable and 34 out of 181 patients (18.7%) had dupilumab-induced blepharoconjunctivitis: either de novo (n = 32) or worsening of underlying blepharoconjunctivitis (n = 2). Most events (27/34; 79.4%) were moderate. A multivariate analysis showed that head and neck AD (OR = 7.254; 95%CI [1.938-30.07]; p = 0.004), erythroderma (OR = 5.635; 95%CI [1.635-21.50]; p = 0.007) and the presence of dry eye syndrome at baseline (OR = 3.51; 95%CI [3.158-13.90]; p = 0.031) were independent factors associated with dupilumab-induced blepharoconjunctivitis. LIMITATIONS: Our follow-up period was 16 weeks and some late-onset time effects may still occur. CONCLUSION: This study showed that most dupilumab-induced blepharoconjunctivitis cases are de novo. AD severity and conjunctivitis at baseline were not found to be associated risk factors in this study.

Purpose: : To determine the presence of SARS-CoV-2 virus in the tear secretion of conjunctivitis patients during the COVID-19 pandemic. Methods: This observational, cross-sectional study was conducted in clinically diagnosed patients with conjunctivitis attending the outpatient services of our institute from July 2021 to December 2021. The tear samples were collected from patients using Schirmer's strips or capillary tubes to detect the presence of SARS-CoV-2 by real-time PCR assay. COVID-19 vaccination and infection status, visual acuity, and clinical features were documented in all cases. Results: A total of 111 patients with symptoms of conjunctivitis were included during the study period. The mean age was 41.1 ± 13.1 years, and the mean duration of symptoms was 7.1 ± 4.4 days, with 74% males. Conjunctival congestion was mild in 69 (62.1%) patients, moderate in 30 (27%) patients, and severe in 12 (10.8%) patients. All except four had superficial punctate keratitis (SPK). Five (4.3%) patients were positive for SARS-CoV-2 RNA in their tear samples. All had mild-moderate conjunctival congestions with variable papiliofollicular reaction and SPKs, superficial hemorrhages were seen in three and pseudomembrane in one patient. They were followed up with telemedicine and three of them developed mild COVID-19-related symptoms and recovered after in-home quarantine. None of them had a previous history of COVID-19 infection and all had received COVID-19 vaccination within 2 weeks to 2 months. Conclusion: SARS-CoV-2 transmission through ocular secretion of conjunctivitis patients cannot be ignored and appropriate COVID-19-preventive behavior should be followed in ocular settings.

INTRODUCTION: In a guinea pig herd with 26 breeding animals, several individuals of all age categories died (16/26) after three animals had been newly introduced from another herd. Furthermore, the population suffered of apathy, anorexia, severe weight loss and conjunctivitis, as well as abortions and stillbirths. At the same time, the owner experienced a SARS-CoV-2 infection with pneumonia, which was confirmed by taking a PCR test. Chlamydia caviae was detected from the conjunctiva and vagina/uterus in one juvenile animal together with an intestinal Cryptosporidium wrairi infection. Oocysts were found histologically in the small intestine, which was confirmed by PCR. C. wairi is a parasite adapted to guinea pigs with zoonotic potential, which causes diarrhoea with frequent deaths in larger guinea pig herds. C. caviae is also a zoonotic pathogen and often the cause of conjunctivitis, pneumonia and abortions in guinea pigs and can lead to upper respiratory tract disease, conjunctivitis but also severe pneumonia in humans. The increased death cases and the clinical signs could be traced back to an infection with Cryptosporidium wrairi, complicated by a co-infection of C. caviae. We suspect that the abortions were caused by C. caviae, but since the population was treated with various antibiotics effective against chlamydial infections, it was no longer possible to verify this by PCR testing. Unfortunately, more animals succumbed and finally only two animals of the originally 26 were left. With this case report, we would like to point out to veterinarians that guinea pigs can be an important source of zoonotic infections for various pathogens, especially since they are popular pets and often come into close contact with children where hygiene might not always be strictly followed.
INTRODUCTION: Dans un groupe de cobayes de 26 animaux reproducteurs, plusieurs individus de toutes les catégories d'âge sont morts (16/26) après l'introduction de trois animaux provenant d'un autre groupe. En outre, la population a souffert d'apathie, d'anorexie, de perte de poids sévère et de conjonctivite ainsi que d'avortements et de mortinatalité. La présence de Chlamydia caviae a pu être détectée dans la conjonctive et le vagin/utérus d'un animal juvénile, ainsi qu'une infection intestinale à Cryptosporidium wrairi. Des oocystes ont été trouvés histologiquement dans l'intestin grêle, ce qui a été confirmé par PCR. C. wairi est un parasite adapté aux cobayes avec un potentiel zoonotique, qui provoque des diarrhées avec des morts fréquentes dans les grands groupes de cobayes. C. caviae est également un agent pathogène zoonotique et est souvent à l'origine de conjonctivites, de pneumonies et d'avortements chez les cobayes ; il peut entraîner des maladies des voies respiratoires supérieures, des conjonctivites mais aussi des pneumonies graves chez l'homme. L'augmentation des cas de décès et les signes cliniques pourraient être attribués à une infection par Cryptosporidium wrairi, compliquée par une co-infection par C. caviae. Nous soupçonnons que les avortements ont été causés par C. caviae, mais comme la population a été traitée avec divers antibiotiques efficaces contre les infections à chlamydia, il n'était plus possible de le vérifier par des tests PCR. Malheureusement, d'autres animaux ont succombé et il ne restait finalement que deux animaux sur les 26 d'origine. Avec ce rapport de cas, nous aimerions attirer l'attention des vétérinaires sur le fait que les cochons d'Inde peuvent être une source importante d'infections zoonotiques pour divers pathogènes, d'autant plus qu'il s'agit d'animaux de compagnie populaires qui sont souvent en contact étroit avec des enfants avec lesquels l'hygiène n'est pas toujours strictement respectée.
