Abstract
Importance Acute infectious conjunctivitis is a common ocular condition with major public health consequences. Objective To assess regional variations and microbial etiologies of acute infectious conjunctivitis to guide treatment. Design, Setting, and Participants In this cross-sectional study, patients with presumed acute infectious conjunctivitis were enrolled in the study at 5 sites (Honolulu, Hawaii; Los Angeles, San Francisco, and San Diego, California; and Petah-Tikva, Israel) from March 2021 to March 2023. Patients with allergic or toxic conjunctivitis were excluded. Main Outcomes and Measures Pathogens were identified by unbiased RNA deep sequencing. Results In all, 52 patients (mean [range] age, 48 [7-80] years; 31 females [60%]) were enrolled at 5 sites (6 patients from Honolulu, 9 from San Diego, 11 from Los Angeles, 13 from San Francisco, and 13 from Petah-Tikva). RNA deep sequencing detected human adenovirus species D in one-quarter of patients (13 of 52). A wide range of pathogens, including human coronavirus 229E, SARS-CoV-2, and herpes simplex virus type 1, was also identified, as well as several bacteria and fungi. Moreover, 62% (32 of 52) of patients presented with purulent discharge, while only 8% (4 of 52) of patients had confirmed bacterial pathogens. Conclusion and Relevance In this cross-sectional study, pathogens associated with acute infectious conjunctivitis varied between all 5 sites in the US and Israel. Purulent discharge was a common presenting sign in this study, with a low specificity for bacteria-associated conjunctivitis, suggesting that further diagnostic workup may be necessary to inform antibiotic stewardship. Additional research on cost-effectiveness of using RNA deep sequencing is needed to ascertain whether it is better to monitor patients clinically until resolution of disease.

Abstract
Viral conjunctivitis is one of the most common acute eye diseases. The fall and winter months are known to be the main season for viral infections which is also reflected in the ophthalmological outpatient clinics. Viral conjunctivitis is often accompanied by symptoms of the upper and lower respiratory tract, fever, chills, arthralgia or skin lesions. The spectrum of pathogens comprises DNA viruses such as Adeno-, Herpes simplex and Molluscum contagiosum as well as RNA viruses. Symptoms caused by pandemic pathogens such as SARS-CoV-2 and mpox viruses can also cause ocular manifestation. Viral conjunctivitis is often self-limiting leaving no residual symptoms, however an ophthalmologist should be consulted if there are inflammatory symptoms of the anterior eye accompanied by visual disturbance. It is particularly important to recognize the affection of corneal or even intraocular structures early to initiate an adequate and effective therapy. Affection of the cornea, vitreus or retina can result in temporary or permanent impairment of the field of vision and visual acuity. The diagnosis is usually made without further tests on the basis of the typical clinical presentation. Rapid tests or PCR diagnostics are also available for confirmation. In most patients the treatment is symptomatically with artificial tears and antibiotic eye drops in cases accompanied by secondary bacterial infections, not prophylactically. If the cornea or other ocular structures are affected by certain viruses, local as well as systemic virostatic therapy is initiated. The most important prophylactic measure is meticulous and consistent hygiene.

Abstract
Viruses account for 80% of all cases of acute conjunctivitis and adenovirus; enterovirus and herpes virus are the common causative agents. In general, viral conjunctivitis spreads easily. Therefore, to control the spread, it is crucial to quickly diagnose illnesses, strictly implement hand washing laws, and sanitize surfaces. Swelling of the lid margin and ciliary injection are subjective symptoms, and eye discharge is frequently serofibrinous. Preauricular lymph node swelling can occasionally occur. Approximately 80% of cases of viral conjunctivitis are caused by adenoviruses. Adenoviral conjunctivitis may become a big global concern and may cause a pandemic. Diagnosis of herpes simplex viral conjunctivitis is crucial for using corticosteroid eye solution as a treatment for adenovirus conjunctivitis. Although specific treatments are not always accessible, early diagnosis of viral conjunctivitis may help to alleviate short-term symptoms and avoid long-term consequences.

Abstract
Eye drops are the most accessible therapy for ocular diseases, while inevitably suffering from their lower bioavailability which highly restricts the treatment efficacy. The introduction of nanotechnology has attracted considerable interest as it has advantages over conventional ones such as prolonged ocular surface retention time and enhanced ocular barrier penetrating properties, and achieving higher bioavailability and improved treatment efficacy. This review describes various ocular diseases treated with eye drops as well as the physiological and anatomical ocular barriers faced with through drug administration. It also summarizes the recent advances regarding the utilization of nanotechnology in developing eye drops, and how to optimize the nanocarrier-based ocular drug delivery systems. The prospective future research directions for nano-based eye drops are also discussed here.

Abstract
65 consecutive patients with presumed microbial keratitis and negative culture tests for bacteria and fungi obtained by corneal curettage were evaluated. All patients had undergone local broad spectrum antibiotic therapy for at least 5 days with no clinical improvement. After 48–72 h of wash-out they underwent scraping of the superior tarsal conjunctiva for cytological examination of cellular morphology in Scanning Electron Microscopy (SEM). The presence of pathogenic microorganisms was detected with this method in 62 of these patients, towards which specific therapy was carried out. Clinical improvement and eradication of microorganisms previously detected by SEM examination were observed in all positive patients over a time between 10 and 49 days. In three patients, no microorganisms were detected, but the presence of inflammatory cells (eosinophils and mast cells) or dry eye findings. This method could be useful to detect the presence of non-isolated microorganisms at common culture tests. The resolution of the infectious keratitis and the eradication of the pathogens at the subsequent cytological examination of cellular morphology in Scanning Electron Microscopy support the validity of the proposed method.

Oman J Ophthalmol 2023; 16:69-74. [PMID: 37007229 PMCID: PMC10062074 DOI: 10.4103/ojo.ojo_180_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 09/03/2022] [Accepted: 12/03/2022] [Indexed: 02/25/2023] Open
Abstract
BACKGROUND Keratoconjunctivitis is one of the most common pathologies worldwide, caused by several infectious and noninfectious factors. This study aimed to determine the effect of povidone-iodine 2% eye drops in treating adenoviral keratoconjunctivitis. METHODS This analytic cross-sectional study was conducted on patients referred to Farabi Eye Hospital Records of patients with adenoviral keratoconjunctivitis, more than 12 years of age, and no allergy to iodine who were treated by povidone-iodine 2% eye drops four times a day were assessed. Data included demographic characteristics, family history of adenoviral keratoconjunctivitis, follicular conjunctivitis, petechial conjunctival hemorrhages, periauricular lymphadenopathy, and the presence of conjunctival pseudomembrane were collected from the records. Discharge decrease, injection decrease, swelling decrease, pseudomembrane formation, periauricular lymphadenopathy, and subepithelial infiltration on the 7thday of assessment by physical examination were reported. RESULTS Patients with a mean (±standard deviation) age of 33.77 (11.01) years were assessed. At the baseline, 95 (99.0%) follicular conjunctivitis, 94 (97.9%) petechial conjunctival hemorrhages, 29 (30.2%) periauricular lymphadenopathy, and 5 (5.2%) conjunctival pseudomembrane were recorded. On the 7thday of treatment, the discharge decreased in 92.7% of patients, and the injection decreased in 90.6%. The swelling decrease was also detected in 79.2% of patients. Subepithelial infiltration was only seen in 21.9% of the study population. Results showed that 2.1% of patients had periauricular lymphadenopathy, and only 13 out of 96 patients (13.5%) had pseudomembrane formation after 7 days. CONCLUSIONS Based on the safety, availability, and tolerability of povidone-iodine and its promising effects on patients with adenoviral keratoconjunctivitis, further clinical trials assessing the impact of this drug in a longer duration of follow-up can be recommended.

Abstract
CLINICAL RELEVANCE This study identifies key signs and symptoms of acute conjunctivitis, that when combined with a point-of-care test, can improve clinician accuracy of diagnosing adenoviral conjunctivitis. BACKGROUND Adenoviral conjunctivitis is a common ocular infection with the potential for high economic impact due to widespread outbreaks and subsequent furloughs from work and school. In this report, we describe clinical signs and participant-reported symptoms that most accurately identify polymerase chain reaction (PCR)-confirmed adenoviral conjunctivitis. METHODS Adults with 'red eye' symptoms of four days or less were enrolled. Participants rated 10 ocular symptoms from 0 (not bothersome) to 10 (very bothersome), and indicated the presence or absence of systemic flu-like symptoms. Clinicians determined the presence or absence of swollen lymph nodes and rated the severity of eight ocular signs using a 5-point scale. An immunoassay targeting adenovirus antigen was utilised for the point-of-care test, and conjunctival swab samples were obtained for subsequent adenovirus detection by PCR analyses. Univariate and multivariate logistic regression models were used to identify symptoms and signs associated with PCR-confirmed adenoviral conjunctivitis. The diagnostic accuracy of these clinical findings, and the potential benefit of incorporating point-of-care test results, was assessed by calculating areas under the receiver operating characteristic curves (AUC). RESULTS Clinician-rated bulbar conjunctival redness, participant-rated eyelid swelling and overall ocular discomfort had the best predictive value in the multivariate logistic regression model with an AUC of 0.83. The addition of the point-of-care test results to these three clinical sign/symptom scores improved diagnostic accuracy, increasing the AUC to 0.94. CONCLUSIONS Conjunctival redness severity and participant-reported eyelid swelling and overall discomfort, along with adenoviral point-of-care test results, were highly predictive in identifying individuals with PCR-confirmed adenoviral conjunctivitis. Improved diagnostic accuracy by clinicians at the initial presenting visit could prevent unnecessary work furloughs and facilitate earlier treatment decisions.

Abstract
PURPOSE To summarize key findings from a Cochrane systematic review of the effectiveness and safety of topical pharmacologic interventions compared with active control or placebo for epidemic keratoconjunctivitis (EKC). DESIGN Systematic review. METHODS We included randomized controlled trials that compared antiseptic agents, virustatic agents, or immune-modulating topical therapies with placebo or an active control. We adhered to Cochrane methods for trial selection, data extraction, risk of bias evaluation, and data synthesis. RESULTS Ten randomized controlled trials with 892 participants with acute or chronic EKC were included. Eight trials compared interventions with artificial tears or saline (n = 4) or with steroids (n = 4); two 3-arm trials contributed data to both comparisons. Estimates suggested that compared with tears, after povidone-iodine (PVP-I) alone (2 studies, 409 participants) more participants with acute EKC had resolution of symptoms (risk ratio [RR] 1.15 [95% confidence interval {CI} 1.07-1.24]) and signs (RR 3.19 [95% CI 2.29-4.45]) within 10 days. In 2 trials comparing treatments with steroid alone or steroid with levofloxacin, fewer eyes treated with PVP-I or polyvinyl alcohol iodine (PVA-I) plus steroid developed subepithelial infiltrates within 21 days (RR 0.08 [95% CI 0.01-0.55]; 69 eyes). No treatment was shown to improve resolution of infiltrates. CONCLUSIONS Low- to very low-level certainty of evidence suggested that PVP-I or PVA-I with steroid may confer some benefit in acute EKC, but imprecision from small sample sizes, the potential risk of bias from inadequate reporting or trial design, and variability in participant selection, outcome measurement, and reporting limit the amount and quality of evidence.

Abstract
IMPORTANCE Acute infectious conjunctivitis is characterized by ocular redness and discharge, and is a common clinical entity. Evidence-based tools to aid the clinical diagnosis of viral vs bacterial conjunctivitis are lacking and may contribute to overprescribing of topical antibiotics. OBJECTIVE To determine the relative prevalence of viral vs bacterial conjunctivitis in adults and children, and to determine which symptoms or signs are suggestive of a viral vs bacterial etiology. DATA SOURCES A MEDLINE search (January 1946-March 2022) yielded 1891 articles. Included articles were rated using a quality score based on a modified Rational Clinical Examination grading system. Methodological quality levels 1 through 4 required a microbiological reference standard for diagnosis, whereas quality level 5 (the lowest quality) used a clinical reference standard for diagnosis. STUDY SELECTION Consecutive series of patients presenting with acute infectious conjunctivitis and case series of viral or bacterial conjunctivitis alone. Thirty-two studies were included in a meta-analysis to determine prevalence and diagnostic accuracy measures; 27 used a microbiological reference standard for diagnosis and 5 used a clinical reference standard for diagnosis. RESULTS In studies involving children (5 studies; 881 patients; mean age, 4.7 years [age range, 1 month-18 years]), the prevalence of bacterial conjunctivitis was higher than viral conjunctivitis (71% vs 16%, respectively, P = .01). In the only study of adults (n = 207 patients; mean age, 25.7 years), the prevalence of viral conjunctivitis was higher than bacterial conjunctivitis (78% vs 16%, respectively, P < .001). For the primary analysis of level 1 (n = 6) and level 2 (n = 5) studies (1725 patients total), the clinical findings that best distinguished a viral etiology for conjunctivitis from a bacterial etiology included pharyngitis (sensitivity range, 0.55-0.58; specificity range, 0.89-0.94; positive likelihood ratio [LR] range, 5.4-9.9), preauricular lymphadenopathy (sensitivity range, 0.17-0.31; specificity range, 0.93-0.94; positive LR range, 2.5-5.6), and contact with another person with red eye (sensitivity, 0.18 [95% CI, 0.14-0.22]; specificity, 0.93 [95% CI, 0.90-0.95]; positive LR, 2.5 [95% CI, 1.6-3.7]). Mucopurulent ocular discharge (sensitivity, 0.76 [95% CI, 0.60-0.87); specificity, 0.66 [95% CI, 0.58-0.73]; positive LR, 2.1 [95% CI, 1.7-2.6]) and otitis media (sensitivity, 0.24 [95% CI, 0.20-0.29]; specificity, 0.91 [95% CI, 0.85-0.94]; positive LR, 2.5 [95% CI, 1.5-4.4]) were associated with the presence of bacterial conjunctivitis. CONCLUSIONS AND RELEVANCE In this review, bacterial conjunctivitis was more common than viral conjunctivitis in children and viral conjunctivitis was more common than bacterial conjunctivitis in adults, although the prevalence estimates were based on limited evidence. Symptoms and signs associated with a higher likelihood of viral conjunctivitis in adults and children included concomitant pharyngitis, an enlarged preauricular node, and contact with another person with red eye, and signs associated with a higher likelihood of bacterial conjunctivitis included the presence of mucopurulent discharge and otitis media, but no single symptom or sign differentiated the 2 conditions with high certainty.

Abstract
PURPOSE To determine the prevalence of adenoviral conjunctivitis in Turkish ophthalmologists, to provide an overview of the treatment and prophylaxis of adenoviral conjunctivitis, and to analyze the data in the context of evidence-based treatment recommendations. METHODS An online questionnaire consisting of 20 multiple-choice questions about the characteristics of the respondents, the individual adenoviral conjunctivitis history of the ophthalmologists, their practice's approaches, and prescription preferences were emailed to Turkish ophthalmologists. RESULTS The survey was emailed to 500 ophthalmologists; 45% of them returned the questionnaire. According to the responses, the history of adenoviral conjunctivitis infections was positive in 46.7% (n: 120), recurrent attack prevalence was 16.2% in ophthalmologists. Lubricants (67.6%) are the most preferred first-line treatment options for adenoviral conjunctivitis, followed by povidone-iodine (59.6%), topical antibiotics (51.1%), topical antivirals (29.3%), topical corticosteroids (26.7%), and topical nonsteroidal anti-inflammatory agents (19.6%). A total of 98.2% preferred to dismiss infected patients. The preferred prophylaxis options were frequent hand washing/use of gloves (97.8%), disinfection of medical devices (95.1%), isolation of infected patients (79.1%), hand hygiene with gemicides (58.7%). The percentage of single-dose eye drop selection was 46.2. CONCLUSIONS The findings of this survey showed that most Turkish ophthalmologists generally follow international guidelines for the treatment of adenoviral conjunctivitis. The treatment algorithm is still controversial, so ophthalmologists should be aware of treatment guideline updates in line with evidence-based recommendations. Having sufficient knowledge of the basic characteristics of viruses is important to control the spread of the disease.

Abstract
BACKGROUND Viruses cause about 80% of all cases of acute conjunctivitis. Human adenoviruses are believed to account for 65% to 90% of cases of viral conjunctivitis, or 20% to 75% of all causes of infectious keratoconjunctivitis worldwide. Epidemic keratoconjunctivitis (EKC) is a highly contagious subset of adenoviral conjunctivitis that has been associated with large outbreaks at military installations and at medical facilities. It is accompanied by severe conjunctival inflammation, watery discharge, and light sensitivity, and can lead to chronic complications such as corneal and conjunctival scarring with discomfort and poor quality of vision. Due to a lack of consensus on the efficacy of any pharmacotherapy to alter the clinical course of EKC, no standard of care exists, therefore many clinicians offer only supportive care. OBJECTIVES To assess the efficacy and safety of topical pharmacological therapies versus placebo, an active control, or no treatment for adults with EKC. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL, which contains the Cochrane Eyes and Vision Trials Register; 2021, Issue 4); Ovid MEDLINE; Ovid Embase; Latin American and Caribbean Health Sciences database (LILACS); ClinicalTrials.gov; and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), with no restrictions on language or year of publication. The date of the last search was 27 April 2021. SELECTION CRITERIA We included randomized controlled trials in which antiseptic agents, virustatic agents, or topical immune-modulating therapy was compared with placebo, an active control, or no treatment. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. MAIN RESULTS We identified 10 studies conducted in Asia, Europe, the Middle East, and North Africa with a total of 892 participants who were treated for 7 days to 6 months and followed for 7 days up to 1.5 years. Study characteristics and risk of bias In most studies participants were predominantly men (range: 44% to 90%), with an age range from 9 to 82 years. Three studies reported information on trial registration, but we found no published study protocol. The majority of trials had small sample sizes, ranging from 18 to 90 participants enrolled per study; the only exception was a trial that enrolled 350 participants. We judged most studies to be at high or unclear risk of bias across risk of bias domains. Findings We included 10 studies of 892 EKC participants and estimated combined intervention effects in analyses stratified by steroid-containing control treatment or artificial tears. Six trials contributed to the comparisons of topical interventions (povidone-iodine [PVP-I], trifluridine, ganciclovir, dexamethasone plus neomycin) with artificial tears (or saline). Very low certainty evidence from two trials comparing trifluridine or ganciclovir with artificial tears showed inconsistent effects on shortening the mean duration of cardinal symptoms or signs of EKC. Low certainty evidence based on two studies (409 participants) indicated that participants treated with PVP-I alone more often experienced resolution of symptoms (risk ratio (RR) 1.15, 95% confidence interval (CI) 1.07 to 1.24) and signs (RR 3.19, 95% CI 2.29 to 4.45) during the first week of treatment compared with those treated with artificial tears. Very low certainty evidence from two studies (77 participants) suggested that PVP-I or ganciclovir prevented the development of subepithelial infiltrates (SEI) when compared with artificial tears within 30 days of treatment (RR 0.24, 95% CI 0.10 to 0.56). Four studies compared topical interventions (tacrolimus, cyclosporin A [CsA], trifluridine, PVP-I + dexamethasone) with topical steroids, and one trial compared fluorometholone (FML) plus polyvinyl alcohol iodine (PVA-I) with FML plus levofloxacin. Evidence from one trial showed that more eyes receiving PVP-I 1.0% plus dexamethasone 0.1% had symptoms resolved by day seven compared with those receiving dexamethasone alone (RR 9.00, 95% CI 1.23 to 66.05; 52 eyes). In two trials, fewer eyes treated with PVP-I or PVA-I plus steroid developed SEI within 15 days of treatment compared with steroid alone or steroid plus levofloxacin (RR 0.08, 95% CI 0.01 to 0.55; 69 eyes). One study found that CsA was no more effective than steroid for resolving SEI within four weeks of treatment (RR 0.84, 95% CI 0.67 to 1.06; N = 88). The evidence from trials comparing topical interventions with steroids was overall of very low level certainty. Adverse effects Antiviral or antimicrobial agents plus steroid did not differ from artificial tears in terms of ocular discomfort upon instillation (RR 9.23, 95% CI 0.61 to 140.67; N = 19). CsA and tacrolimus eye drops were associated with more cases of severe ocular discomfort, and sometimes intolerance, when compared with steroids (RR 4.64, 95% CI 1.15 to 18.71; 2 studies; N = 141). Compared with steroids, tacrolimus did not increase the risk of elevated intraocular pressure (RR 0.07, 95% CI 0 to 1.13; 1 study; N = 80), while trifluridine conferred no additional risk compared to tear substitute (RR 5.50, 95% CI 0.31 to 96.49; 1 study; N = 97). Overall, bacterial superinfection was rare (one in 23 CsA users) and not associated with use of the intervention steroid (RR 3.63, 95% CI 0.15 to 84.98; N = 51). The evidence for all estimates was of low or very low certainty. AUTHORS' CONCLUSIONS The evidence for the seven specified outcomes was of low or very low certainty due to imprecision and high risk of bias. The evidence that antiviral agents shorten the duration of symptoms or signs when compared with artificial tears was inconclusive. Low certainty evidence suggests that PVP-I alone resolves signs and symptoms by seven days relative to artificial tears. PVP-I or PVA-I, alone or with steroid, is associated with lower risks of SEI development than artificial tears or steroid (very low certainty evidence). The currently available evidence is insufficient to determine whether any of the evaluated interventions confers an advantage over steroids or artificial tears with respect to virus eradication or its spread to initially uninvolved fellow eyes. Future updates of this review should provide evidence of high-level certainty from trials with larger sample sizes, enrollment of participants with similar durations of signs and symptoms, and validated methods to assess short- and long-term outcomes.

Abstract
Purpose To evaluate the ocular surface properties in epidemic keratoconjunctivitis (EKC) patients during healing process, and to detect the damage on conjunctival goblet cells. Methods Bilateral EKC patients confirmed with polymerase chain reaction (PCR) testing were included. Firstly (Group 1) and secondly (Group 2) affected eyes were compared. Ocular surface parameters were performed at the first visit and first month. Results The study included 34 eyes of 17 patients. The mean age was 44.54 ± 16.80 (21-70) years (FM/M 20/14). The ocular findings in Groups 1 and 2 were not significant. For Groups 1 and 2, OSDI was 53.53 ± 23.01 and 35.90 ± 22.19 (p 0.03), tear osmolarity was 309.12 ± 19.38 and 297.47 ± 8.27 mOsm/µL (p 0.029), OSSS was 1.00 ± 0.79 and 0.18 ± 0.39 (p 0.001), T-BUT was 3.59 ± 2.29 and 6.00 ± 1.83 s (p 0.002), and Schirmer's 1 test was 10.94 ± 8.42 and 16.76 ± 9.05 mm (p 0.061), respectively. In Groups 1 and 2, the IC was Grade (G) 0 in 23.5% and 17.6%, G1 in 35.3% and 41.2%, and G2 in 41.2% and 41.2%, respectively. The ocular surface properties were worse in Group 1 than Group 2, and the difference was significant except for Schirmer's 1 test and IC. Conclusions Dry eye disorder is a complication of EKC and may cause a significant decrease in quality of life.

Abstract
PURPOSE To evaluate the safety and efficacy of a single, in-office administration of 5% povidone-iodine (PVP-I) compared to artificial tears (AT) for adenoviral conjunctivitis (Ad-Cs). DESIGN Double-masked pilot randomized trial. METHODS Patients presenting with presumed adenoviral conjunctivitis were screened at 9 U.S. clinics. INCLUSION CRITERIA ≥18 years of age, symptoms ≤4 days, and a positive AdenoPlus test. EXCLUSION CRITERIA thyroid disease, iodine allergy, recent ocular surgery, and ocular findings inconsistent with early-stage Ad-Cs. Randomization was to a single administration of 5% PVP-I or AT in 1 eye and examinations on days 1-2, 4, 7, 14, and 21 with conjunctival swabs taken at each visit for quantitative polymerase chain reaction. Primary outcome was percent reduction from peak viral load. Secondary outcomes were improvement in clinical signs and symptoms. RESULTS Of 56 patients randomized, 28 had detectable viral titers at baseline. Day 4 posttreatment, viral titers in the 5% PVP-I and AT groups were 2.5% ± 2.7% and 14.4% ± 10.5% of peak, respectively (P = .020). Severity of participant-reported tearing, lid swelling, and redness as well as clinician-graded mucoid discharge, bulbar redness, and bulbar edema were lower in the 5% PVP-I group than AT group on day 4 (P < .05). After day 4, viral titers and severity of signs and symptoms decreased markedly in both groups and no differences between groups were detected. CONCLUSIONS Pilot data suggest a single, in-office administration of 5% PVP-I could reduce viral load and hasten improvement of clinical signs and symptoms in patients with Ad-Cs.

Abstract
Importance Adenoviral conjunctivitis is highly contagious, can be associated with systemic infections, and can cause chronic visual impairment. It accounts for a large proportion of acute conjunctivitis. Outbreaks of epidemic keratoconjunctivitis (EKC) are costly in terms of productivity loss from work furloughs and spread to patients and have resulted in clinic and departmental closures. Objective To examine the institutional cost savings of a policy to diagnose adenoviral conjunctivitis and triage and furlough medical center employees with this condition to prevent outbreaks. Design, Setting, and Participants This quality improvement study assessed Johns Hopkins Medicine employees with red eye from November 1, 2011, through October 31, 2018, who were triaged at the occupational health clinic whose conditions were diagnosed using polymerase chain reaction (PCR) validated for adenoviral conjunctivitis. Interventions Only employees with positive PCR test results were furloughed, with furlough length tailored to subtype (a minimum of 2 weeks for EKC and 1 week otherwise). Main Outcomes and Measures Total number of furloughs avoided and cost savings associated with reducing unnecessary furloughs. Results Of 2142 employees with red eye, 1520 (71.0%) underwent PCR testing; 130 (8.6%) had positive adenoviral PCR test results, of whom 41 (31.5%) had EKC. Furloughing 130 employees with positive PCR test results vs furloughing all 1520 employees clinically suspected of having adenoviral conjunctivitis represented an estimated annual savings of $442 073, or $3 094 511 during 7 years. The cost of performing PCR on employees suspected of having adenoviral conjunctivitis was 5.0% of the cost associated with furloughing all employees with red eye. No outbreaks occurred. Conclusions and Relevance In this quality improvement study, this policy, notable for development and use of PCR for adenoviral conjunctivitis on a large scale, resulted in substantial cost savings from fewer work furloughs compared with the number of employees who would have been furloughed based on clinical diagnosis. These results may provide impetus for policy adoption by other institutions and for development of a rapid, sensitive, and specific diagnostic test for adenoviral conjunctivitis.

Abstract
PURPOSE To evaluate long-term visual and refractive outcomes of corneal wavefront-guided transepithelial photorefractive keratectomy (t-PRK) with mitomycin C for the treatment of corneal opacities secondary to adenoviral epidemic keratoconjunctivitis. METHODS Records of patients who underwent corneal wavefront-guided t-PRK with excimer laser from January 2012 to December 2018 were retrospectively reviewed. Preoperative and postoperative uncorrected visual acuity, best-spectacle corrected visual acuity, slit-lamp biomicroscopic examination findings, manifest refraction, and corneal aberrations and fundus examination findings were evaluated. RESULTS Twenty-two eyes of 22 patients comprising 12 male (55%) and 10 female (45%) were treated. The mean age was 34.5 ± 10.8 years (range 19-55). The mean follow-up time was 34.4 ± 17.50 months (range 13-61 months). There was a statistically significant improvement in UCVA and BSCVA (p < 0.001 and p = 0.02), and there was a significant decrease in total higher-order aberrations, spherical, coma and trefoil aberration at postoperative first year (p < 0.001 in each). In two eyes of two patients, minimal haze formation was observed after the procedure, and both eyes were treated with topical steroid. No recurrence was observed in subepithelial infiltrates in any patient during long-term follow-up. CONCLUSION In long-term clinical follow-up, corneal wavefront-guided t-PRK treatment is an effective and reliable treatment method for rehabilitation of visual impairment due to corneal scars following adenoviral infections, in properly selected patients.

Abstract
Conjunctivitis is a commonly encountered condition in ophthalmology clinics throughout the world. In the management of suspected cases of conjunctivitis, alarming signs for more serious intraocular conditions, such as severe pain, decreased vision, and painful pupillary reaction, must be considered. Additionally, a thorough medical and ophthalmic history should be obtained and a thorough physical examination should be done in patients with atypical findings and chronic course. Concurrent physical exam findings with relevant history may reveal the presence of a systemic condition with involvement of the conjunctiva. Viral conjunctivitis remains to be the most common overall cause of conjunctivitis. Bacterial conjunctivitis is encountered less frequently and it is the second most common cause of infectious conjunctivitis. Allergic conjunctivitis is encountered in nearly half of the population and the findings include itching, mucoid discharge, chemosis, and eyelid edema. Long-term usage of eye drops with preservatives in a patient with conjunctival irritation and discharge points to the toxic conjunctivitis as the underlying etiology. Effective management of conjunctivitis includes timely diagnosis, appropriate differentiation of the various etiologies, and appropriate treatment.

Abstract
Purpose To determine whether topical tobramycin 0.3%/dexamethasone 0.1% plus ozonized oil eye drops reduces clinical signs and infectious viral titers of presumed viral conjunctivitis more than tobramycin/dexamethasone eye drops alone. Methods Prospective, single-blind, randomized, parallel-groups trial. Eighty patients with a clinical diagnosis of presumed viral conjunctivitis were randomizedly divided into two treatment groups: a study group and a control group, 40 for each group. Patients in the study group received topical tobramycin 0.3%/dexamethasone 0.1% eye drops, plus ozonized oil eye drops, both four times daily; patients in the control group received only topical tobramycin 0.3%/dexamethasone eye drops four times daily. The treatment was for seven days in both groups. Swabs were taken from the conjunctival fornix for adenovirus PCR analysis on the day of recruitment and at seven days follow-up. Clinical signs were also recorded on the day of recruitment and at follow-up examination: the main outcomes were conjunctival injection and conjunctival chemosis, graded on a 4-point clinical scale, presence or absence of superficial punctate keratitis and subepithelial corneal infiltrates. Results No statistically significant difference was reached in adenoviral infection negativization between the two groups, although the study group showed a higher number of PCR negative results at seven days follow-up. PCR real time detected adenoviral infection in 17 of 24 patients on the day of recruitment and it was positive in 4 patients on the seventh day (viral positivity reduction of 76%). In the control group PCR was positive for adenovirus in 18 of 24 patients on the day of recruitment and in 7 patients at seven days follow-up (reduction of 61%). There was statistically significant difference on conjunctival clinical signs between the study and control groups. Significant difference was also found on superficial punctate keratitis resolution between the study and the control group. In the former superficial punctate keratitis was detected in 14 eyes on the first day and in 5 eyes after seven days while in the latter superficial punctate keratitis was found in 124 eyes on the first day and in 6 eyes on the seventh day. No difference was found in subepithelial corneal infiltrates appearance between the two groups. Conclusions The use of ozonized-oil containing eye drops in combination with topical tobramycin 0.3%/dexamethasone 0.1% eye drops four times daily seems to reduce the signs of conjunctivitis, and the duration of viral infection, although it does not affect the subepithelial corneal infiltrates appearance.

Abstract
A pandemic outbreak of a viral respiratory infection (COVID-19) caused by a coronavirus (SARS-CoV-2) prompted a multitude of research focused on various aspects of this disease. One of the interesting aspects of the clinical manifestation of the infection is an accompanying ocular surface viral infection, viral conjunctivitis. Although occasional reports of viral conjunctivitis caused by this and the related SARS-CoV virus (causing the SARS outbreak in the early 2000s) are available, the prevalence of this complication among infected people appears low (~1%). This is surprising, considering the recent discovery of the presence of viral receptors (ACE2 and TMPRSS2) in ocular surface tissue. The discrepancy between the theoretically expected high rate of concurrence of viral ocular surface inflammation and the observed relatively low occurrence can be explained by several factors. In this work, we discuss the significance of natural protective factors related to anatomical and physiological properties of the eyes and preventing the deposition of large number of virus-loaded particles on the ocular surface. Specifically, we advance the hypothesis that the standing potential of the eye plays an important role in repelling aerosol particles (microdroplets) from the surface of the eye and discuss factors associated with this hypothesis, possible ways to test it and its implications in terms of prevention of ocular infections.

Abstract
Although current studies suggested that conjunctivitis is not a common presentation of coronavirus disease 2019 (COVID-19), several studies have reported the presence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in ocular secretions. Coronavirus had not yet been successfully cultured from tears or conjunctival swabs in humans, neither SARS-CoV-2 nor SARS-CoV. However, live feline coronavirus has been isolated from conjunctival swabs. In addition, infection of COVID-19 through unprotected eye exposure had been suspected in several articles. Reports of ophthalmologists and otolaryngologists died of COVID-19 also raised concern on ocular transmission. As a result, we strongly suggest that personal protective equipment (PPE) should cover the mouth, nose, and eyes of ophthalmologists, especially when conjunctivitis caused by SARS-CoV-2 is clinically indistinguishable from other viral follicular conjunctivitis.

Br J Ophthalmol 2020; 105:614-618. [PMID: 32563992 DOI: 10.1136/bjophthalmol-2020-316196] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 05/11/2020] [Accepted: 06/01/2020] [Indexed: 11/03/2022]
Abstract
PURPOSE Investigation of the efficacy and safety of 12 months of topical tacrolimus 0.03% ointment treatment against the subepithelial infiltrates (SEIs) due to adenoviral keratoconjunctivitis (AKC) resisting at least 2 years was aimed. METHODS This case series included consecutive patients with SEIs secondary to AKC who were resistant to topical steroid and ciclosporin-A (CSA) treatment and treated with topical 0.03% tacrolimus (Protopic; Fujisawa Healthcare, Teva, Deerfield, Illinois, USA) for 12 months, at least 2 years after AKC. For the evaluation of treatment efficacy, best-corrected visual acuity (BCVA), Fantes score, corneal subepithelial infiltrate score (CSIS), Oxford score, Schirmer and tear breakup time results were evaluated. Intraocular pressure and complaints of the patients were followed for evaluating the safety profile of the treatment. The patients were followed after the baseline visit at the 1st, 3rd, 6th and 12th month. RESULTS 15 eyes of 11 patients with SEIs and 16 eyes of 16 healthy controls were included in this study. 1 patient (9.1%) could not tolerate the treatment. Significant improvements in BCVA, CSIS, Fantes score and Schirmer results were observed in the study group starting from the 3rd-month visit, and the improvements persisted until the end of 12 months of treatment. CONCLUSION Topical 0.03% tacrolimus might show efficacy against the SEIs persisting at least 2 years despite corticosteroid and/or CSA treatment without any prominent side effect. While at least a period of 3 months was necessary for a significant improvement in the BCVA, SEIs and Schirmer results, a period of 6 months was necessary for a decrease in Oxford score.

Abstract
COVID-19 has been declared a pandemic by the World Health Organization on March 11, and since then, more than 3 million cases and a quarter million deaths have occurred due to it. Lately, there is a growing evidence for an ophthalmologic symptom (conjunctivitis) to be connected with the disease. This seems to happen in early stages of the infection by SARS-CoV-2, and thus, it is of major importance to understand the mechanism through which the virus can facilitate such a symptom. Here, we are proposing a molecular mechanism through which the novel coronavirus could act in order to affect the eye and use it as another, secondary but alternative, point of entry to the host organism.

Abstract
The diagnosis of acute infectious conjunctivitis can be difficult. Clinical ambiguity exists between the acute viral and bacterial as well as the allergic forms, which can confound diagnosis. Also, discrimination between viral or bacterial origins of infectious conjunctivitis based on historical, nonspecific, clinical signs and symptoms contributes to a high rate of misdiagnosis and overuse of antibiotic treatment. Therefore, in order to effectively treat acute infectious conjunctivitis, physicians must be aware of the clinical signs and symptoms and available diagnostic tests that can provide a more accurate differential diagnosis.

Abstract
PURPOSE: The purpose of the study was to assess the treatment protocol of topical 2.5% Povidone-Iodine (PovI) and 0.1% fluorometholone (FluM) for Adenoviral Epidemic keratoconjunctivitis (EKC) in reducing the duration and severity of the disease as compared to conventional treatment. This was a retrospective case–control study. MATERIALS AND METHODS: Cases were defined as patients with EKC receiving the treatment protocol and conjunctival swab taken for polymerase chain reaction. Controls were defined as similar patients receiving conventional treatment protocol. Forty-one cases and 35 controls were identified for analysis. Cases were treated with a protocol using 2.5% povidone-iodine eye drops and 0.1% FluM eye drops. Controls received conventional treatment until resolution of signs and symptoms. Both the groups were followed up for 1 month. Data collected were analyzed for effect of the two treatment protocols on the duration of EKC, rate of recovery, and incidence of complications. RESULTS: The treatment protocol was significantly better than conventional treatment protocol in achieving cure (P = 0.002) with large effect size. The proportion of cases achieving cure was significantly higher with treatment protocol (64% vs. 11% at 5 days, P < 0.001) by 5 days. There was a significant reduction of the subepithelial infiltrates (SEI) incidence group (10% vs. 57%, P < 0.001). There were no SEI at 1 month in the treatment group (0% vs. 31%). CONCLUSION: Treatment protocol used in our study can significantly reduce the severity and duration of EKC. It can prevent chronic keratitis in majority of cases. Since povidone-iodine is nonspecific and virucidal for adenovirus, this therapy can be used for other types of adenoviral conjunctivitis.

Abstract
Human adenovirus infection of the ocular surface is associated with severe keratoconjunctivitis and the formation of subepithelial corneal infiltrates, which may persist and impair vision for months to years following infection. Long term pathology persists well beyond the resolution of viral replication, indicating that the prolonged immune response is not virus-mediated. However, it is not clear how these responses are sustained or even initiated following infection. This review discusses recent work from our laboratory and others which demonstrates different entry pathways specific to both adenovirus and cell type. These findings suggest that adenoviruses may stimulate specific pattern recognition receptors in an entry/trafficking-dependent manner, leading to distinct immune responses dependent on the virus/cell type combination. Additional work is needed to understand the specific connections between adenoviral entry and the stimulation of innate immune responses by the various cell types present on the ocular surface.

Abstract
PURPOSE Conjunctivitis, or inflammation of the conjunctiva, is a common condition that can be caused by infectious (eg, bacterial or viral infections) and noninfectious (eg, allergy) etiologies. Treatment involves diagnosis of the underlying cause and use of appropriate therapies. A broad-spectrum therapy that can address multiple etiologies, and also the accompanying inflammation, would be very useful. In this review, we discuss the usefulness of topical ophthalmic corticosteroids and ophthalmic formulations that combine corticosteroids with anti-infectives/antibiotics for treating acute infectious conjunctivitis. METHODS A review of the published literature and relevant treatment guidelines. RESULTS Topical corticosteroids are useful in treating ocular inflammation, but most treatment guidelines recommend steroid use generally in severe cases of conjunctivitis. This is partly due to risks associated with steroid use. These risks include potential for prolonging adenoviral infections and potentiating/worsening herpes simplex virus infections, increased intraocular pressure, glaucoma, and cataracts. Most of these perceived risks are not, however, supported by high-quality clinical data. They are also associated with long-term steroid uses that are dissimilar to applications for infectious conjunctivitis. Clinical data show that ophthalmic formulations that combine corticosteroids with broad-spectrum anti-infectives could be effective and well tolerated when used for short-term treatment (≤2 weeks). CONCLUSIONS Corticosteroids, in combination with anti-infectives, could be a promising treatment option for acute conjunctivitis subject to development of further evidence on their effectiveness and safety in conjunctivitis treatment.

Abstract
PURPOSE The etiology of conjunctivitis is often misdiagnosed. An ideal diagnostic test would identify all possible infectious causes. In this study, we apply unbiased metagenomic RNA deep sequencing (MDS) to identify pathogens causing conjunctivitis. DESIGN Molecular study of prospectively collected conjunctival swabs from patients with presumed infectious conjunctivitis. PARTICIPANTS Patients with presumed acute infectious conjunctivitis. METHODS Conjunctival swabs were collected from patients presenting with acute conjunctivitis. Swabs were processed for MDS. Pathogens were identified using a rapid computational pipeline to analyze the nonhost sequences obtained from MDS. Differential gene expression analysis was performed to evaluate for host transcriptome signatures for infectious types. Clinical samples were deidentified, and laboratory personnel handling the samples and interpreting the data were masked. MAIN OUTCOME MEASURES Pathogens and differential transcripts identified by MDS. RESULTS Metagenomic RNA deep sequencing detected pathogens in 86% (12/14) of the patients tested. Swabs from 10 of 14 patients were positive for human adenovirus (HAdV) while swabs from 2 of 14 patients were positive for Vittaforma corneae (a parasitic fungal species of the microsporidia group). Samples positive for HAdV by RNA-seq were independently verified in a CLIA-certified laboratory. Pathogen-directed polymerase chain reaction confirmed the presence of V. corneae genome in the samples positive by RNA-seq. Local host transcriptome analysis identified 12 differentially expressed genes that provided distinct expression signatures for patients infected with HAdV compared with V. corneae. CONCLUSIONS Metagenomic RNA deep sequencing can reliably detect and quantify common and rare pathogens causing conjunctivitis, and identify strains. The unbiased nature of metagenomic RNA deep sequencing allowed an expanded scope of pathogen detection, including fungal species not commonly associated with acute conjunctivitis. In addition, the identification of infection type-specific local host transcriptome signatures may allow for pathogen detection even when the pathogen load is too low for direct identification.

Abstract
Purpose To evaluate the clinical safety and efficacy of povidone-iodine (PVP-I) 0.6%/dexamethasone (DEX) 0.1% ophthalmic suspension vs vehicle in patients with clinically suspected acute viral conjunctivitis. Patients and methods This was a randomized, double-masked, parallel-group, vehicle-controlled study. Adults with a clinical diagnosis of suspected acute viral conjunctivitis were randomized 1:1 to PVP-I/DEX ophthalmic suspension or vehicle bilaterally four times daily for 5 days (Days 1–5). Evaluation was on Days 1, 3 (+1-day window), and 6 (+1). Patients with signs of acute viral conjunctivitis at the Day 6 visit received open-label PVP-I/DEX for five additional days and were evaluated on Day 11–14. The primary efficacy endpoint was clinical resolution of acute viral conjunctivitis in the study eye at the Day 6 visit. Results Overall, 132 patients were randomized and received treatment (PVP-I/DEX, n=66; vehicle, n=66); 38 patients continued into the open-label portion of the study. Not enough patients with confirmed adenoviral conjunctivitis (n=32/132) were enrolled to assess the primary endpoint, although there were some efficacy trends in the PVP-I/DEX group for global clinical score (sum of watery conjunctival discharge and bulbar conjunctival redness). There were no serious treatment-emergent adverse events (TEAEs) and no patients discontinued due to a TEAE. In the masked phase, 56.1% of patients receiving PVP-I/DEX experienced at least one TEAE vs 43.9% in the vehicle group; 78.9% of patients in the open-label phase experienced at least one TEAE. Most TEAEs were mild in severity. Conclusion PVP-I/DEX ophthalmic suspension administered for ≤14 days had a favorable safety profile and was generally well tolerated.

Abstract
Adenoviral conjunctivitis comprises a large number of physician office visits in the United States and places a great financial burden on health care. It is estimated that the incidence of adenovirus infection to be as high as 20 million cases per year in the United States. There are multiple adenovirus serotypes, each associated with different types and severity of infection. Ocular manifestations of adenovirus include epidemic keratoconjunctivitis, pharyngoconjunctival fever, and nonspecific conjunctivitis. Adenoviral conjunctivitis is primarily a clinical diagnosis. Laboratory diagnosis is available although until recently rarely used. At present, there is no established or approved specific effective drug against adenovirus. Treatment is primarily supportive and includes artificial tears and cool compresses. Topical antibiotics are only indicated if a bacterial coinfection is suspected or in high-risk patients such as children. Prevention against this extremely contagious disease is of utmost importance. Although most cases are self-limited and have a relatively benign course, permanent visual disability can occur. For this reason, it is imperative that all eye care providers are capable of diagnosing and effectively treating these patients, and also preventing the spread of this contagious disease to others.

Abstract
ObjectiveTo describe the 5-year findings after a policy to screen for, diagnose, and isolate medical center employees with adenoviral conjunctivitis was implemented.DesignObservational report with a retrospective evaluation of a current quality improvement initiative.SettingJohns Hopkins Medicine, Baltimore, Maryland.ParticipantsJohns Hopkins Medicine employees.MethodsData were retrieved from records maintained for this initiative, in which employees with suspected adenoviral conjunctivitis were evaluated in the Occupational Health Clinic and swabbed for polymerase chain reaction (PCR) testing for adenoviral conjunctivitis. Signs, symptoms, work area, diagnoses, and disposition of employees with eye complaints as well as PCR result and adenoviral type were recorded. Five-year data were reviewed.ResultsFrom 2011 to 2016, of 10,000 full-time equivalent employees, 1,059 employees visited the Occupational Health Clinic with suspicion of adenoviral conjunctivitis. Of these, 104 (10%) were PCR positive for adenovirus. Of these PCR-positive employees, 26 (25%) had the worst clinical presentation, epidemic keratoconjunctivitis (EKC). The Outpatient Pharmacy had the highest number of adenoviral conjunctivitis cases (n=9). The proportion of red-eye employees having PCR-positive adenoviral conjunctivitis increased over 5 years (P<.005, Cochrane-Armitage test for trend) as did the proportion of employees with EKC (P<.05). The proportion of employees with EKC caused by type 37 also increased (P<.05).ConclusionsAdenoviral conjunctivitis represents 10% of employee cases clinically suspected of this infection. Employees in patient-care areas should be screened even if they have no direct patient contact. Despite increases in the proportions of adenoviral conjunctivitis and of EKC over 5 years, no outbreaks occurred. This policy helps identify incipient EKC outbreaks and guides infection control efforts.

Abstract
Human adenovirus (HAdV) is a major cause of viral conjunctivitis. The various serotypes implicated in the causation are 3, 4, 8, 19 and 37. The present study aimed to know the circulating types of HAdV causing acute conjunctivitis in North India. A total of 23 conjunctival swabs were collected from patients with clinically suspected acute viral conjunctivitis during 2014-2015. The HAdV was implicated in the etiology in 65.2% of cases. The sequencing of representative samples using hexon gene suggests the presence of serotype 8 and 4. The serotype eight sequences showed 99%-100% similarity with other Indian strains. The phylogenetic analysis showed that the current circulating serotypes, responsible for conjunctivitis, belonged to epidemic keratoconjunctivitis strains.

[PMID: 29558885 PMCID: PMC5859447 DOI: 10.1186/s12879-018-3014-z] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Accepted: 02/28/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Human adenovirus (HAdV)-associated acute conjunctivitis is a common infectious disease and causes significant morbidity among residents in Beijing, China. However, little is known about the epidemiology and type distribution of acute adenoviral conjunctivitis in Beijing. METHODS Acute conjunctivitis surveillance was conducted in 18 hospitals in Beijing from July through October during 2011-2013. HAdVs were detected by PCR from eye swab and types were determined by partial hexon and fiber gene sequencing. Risk factors associated with adenoviral conjunctivitis were analyzed. RESULTS Of 876 conjunctivitis cases, 349 (39.8%) were HAdV positive. HAdV detection was most common in conjunctivitis patients aged 18-40 years; patients with contact history with a conjunctivitis case; patients with specimen collected on days 4-6 post symptom onset and patients who worked in food service as catering attendants. Fifteen types were identified among adenoviral conjunctivitis cases. Five HAdV types (HAdV-4, - 37, - 53, - 64 and - 8) accounted for 81.1% of all adenoviral conjunctivitis cases. HAdV-37, - 4 and - 53 were the most common types associated with adenoviral conjunctivitis in 2011, 2012 and 2013, respectively. CONCLUSION Multiple HAdV types were associated with acute conjunctivitis in Beijing. Predominant types associated with adenoviral conjunctivitis circulating in Beijing varied from year to year.

Abstract
OBJECTIVE Non-interventional, observational, epidemiology study to assess clinical characteristics and frequency of adenovirus conjunctivitis diagnosed by AdenoPlus® in patients who presented with signs and symptoms of acute conjunctivitis. Safety aspects during use of the test were analyzed as well. METHOD This analysis presents the data obtained from the 386 patients enrolled in Spain. Patients had to present with acute signs and symptoms of conjunctivitis ≤7days. The minimum age was 1year old. Patients who had already used local antiviral therapies, topical steroids or immuno-modulators were not allowed to enter the study. A standardized questionnaire was used to collect patient's ocular history and test results. RESULTS A total of 386 patients were recruited in 22 sites, being analyzed 329 patients. Among them, the percentage of "AdenoPlus® positive" was 36,2% (119/329). Before the test was performed, in 84,1% of the cases, investigators believed that the conjunctivitis was of viral origin but only 50,3% of the investigators had their clinical assessment confirmed by the test. Patients who tested positive for adenoviral conjunctivitis presented higher percentages of signs and symptoms than the rest of the patients. CONCLUSIONS None of the signs or symptoms could be qualified as pathognomonic of the disease, being difficult for the clinicians to perform an accurate diagnosis. AdenoPlus® test is an antigen based immunoassay test that detects the presence of adenovirus directly from tears, and it can be an useful tool to help early differential diagnosis in patients with conjunctivitis signs and symptoms lasting for less than or equal to 7days.

Abstract
OBJECTIVE To determine the sensitivity and specificity of the AdenoPlus test compared with real-time polymerase chain reaction (PCR) and to determine whether there was a reduction in antibiotic prescriptions with the use of AdenoPlus compared with the previous year. PATIENTS AND METHODS A total of 125 patients with suspected infectious conjunctivitis were accrued from June 4, 2015, through September 27, 2015. Forty-six participants from the prospective cohort completed both AdenoPlus and PCR testing. Two hundred fifty age-matched individuals were in the retrospective cohort. RESULTS There was a significant reduction in the percentage of patients who received an antibiotic ophthalmic prescription in the prospective cohort vs the retrospective cohort (32% vs 45%; χ2P=.01). AdenoPlus test sensitivity was 50% (5 of 10) and specificity was 92% (33 of 36) compared with real-time PCR testing. CONCLUSION The AdenoPlus test has high specificity for diagnosing adenoviral conjunctivitis but lower sensitivity than has been previously published. These data suggest that negative AdenoPlus results should be confirmed by real-time PCR owing to the low overall sensitivity of AdenoPlus observed.

Abstract
Background Viral conjunctivitis are the most frequent infections in ophthalmology clinics. The diagnosis is usually relying on clinical findings and medical history. However, topical antibiotics are often used unnecessarily addition to symptomatic treatment because of unsure agents. We aimed to detect the Adenovirus, Coxsackievirus and Enterovirus from conjunctiva and pharyngeal samples of patients. Methods The conjunctiva and pharyngeal samples of the patients with conjunctivitis were taken by Virocult transport media and kept at −80 ̊C up to study day. Adenovirus spp, Enterovirus 70 and Enterovirus 71, Coxsackie A24 and Coxsackie A16 were detected by real-time PCR. Samples from healthy health care workers of ophthalmology clinic were used for control group. Results A total of 176 samples (conjunctival and pharyngeal samples of 62 patient and 26 healthy subjects) were included. The mean age of 34 (55.7%) male and 27 (44.3%) female patients was 34 ± 17. Twenty five (40.3%) of the patients were receiving antibiotic drops at first visit. The main etiologic agent in conjunctival samples was found to be Adenovirus (46/62, 74.2%) followed by Enterovirus 70 (4/62, 6.4%) and Enterovirus 71 (4/62, 6.4%). Coxsackievirus 16 and 24 were also found in 2 patients (1/62 each, 1.6%). Pharyngeal samples were also positive for Adenovirus (20/62, 32.3%), Enterovirus 70 and 71 (7/62, 11.3% and 5/62, 8.1% respectively), Coxsackievirus 16 and 24 (2/62, 3.2% and 1/61, 1.6%). Conclusions It is very difficult in viral conjunctivitis to make clinical differentiation caused by different agents because of common clinical signs and symptoms. In routine clinical work, the viral conjunctivitis usually related with Adenovirus. But almost one fourth of the patients’ conjunctivitis were not related to Adenovirus, which shows the importance of the laboratory diagnostics. True diagnosis plays an important role on prevention of contamination and unnecessary use of antibiotics in viral conjunctivitis.

Abstract
"Red eye" is used as a general term to describe irritated or bloodshot eyes. It is a recognizable sign of an acute/chronic, localized/systemic underlying inflammatory condition. Conjunctival injection is most commonly caused by dryness, allergy, visual fatigue, contact lens overwear, and local infections. In some instances, red eye can represent a true ocular emergency that should be treated by an ophthalmologist. A comprehensive assessment of red eye conditions is required to preserve the patients visual function. Severe ocular pain, significant photophobia, decreased vision, and history of ocular trauma are warning signs demanding immediate ophthalmological consultation.

Abstract
PURPOSE To study the epidemiological and clinical aspects of acute enteroviral and adenoviral conjunctivitis. PATIENTS AND METHODS A prospective study was conducted between January 1st and October 31st, 2015, jointly between two Ophthalmology services and a virology laboratory, which identified 51 patients. Were included all patients who presented a painful red eye without loss of visual acuity associated with secretions,evolving for less than 4weeks RESULTS: The mean age was 32 years, and the sex ratio 1:1. Over half of our patients (61%) came from populous districts. A history of the virus "going around" was reported by 30 patients (59% of cases). Virological testing was positive in 35 patients (68.7% of cases). Over 90% of samples collected during the first week of clinical signs were positive. CONCLUSION Viral conjunctivitis is a contagious condition, the spread of which is favored by promiscuity. Adenovirus and enterovirus are the main causative agents. They are present on an endemic scale in Senegal; thus, the need for better epidemiological surveillance in order to limit spread.
