Assessment of SARS-CoV-2 virus in the tear secretion of conjunctivitis patients during COVID-19 pandemic.

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.

Severe Acute Respiratory Syndrome Coronavirus 2-Associated Blepharoconjunctivitis and Erythema Multiforme-Like Rash in a Young Man.

PURPOSE: The aim of this study was to describe the diagnosis and management of bilateral blepharoconjunctivitis and erythema multiforme (EM)-like illness in an otherwise healthy young man who tested positive for severe acute respiratory syndrome coronavirus (SARS-CoV)-2. METHODS: This is a case report of a 27 year-old man with a positive result for SARS-CoV-2 testing who presented with fever, eye redness, oral ulcerations, cough, sore throat, and progressive rash suspicious for EM-like illness. RESULTS: A SARS-CoV-2-positive patient presented to the emergency room with a progressing skin rash, bilateral conjunctivitis, and oropharyngeal mucosal ulcers. On initial ophthalmic examination, visual acuity was 20/25 both eyes (OU), and slit lamp examination demonstrated erythema and ulceration of the eyelid margins with fluorescein uptake at the mucocutaneous junction OU. The patient was admitted for observation and supportive treatment. During and after his hospital stay, he was treated with systemic and topical steroids, topical cyclosporine ophthalmic drops, erythromycin ophthalmic ointment, and artificial tears. At his 1-week follow-up visit after hospital discharge, the patient had complete resolution of his skin findings and improvement of his ocular and oral mucosal findings. Laboratory workup and imaging studies searching for other potential autoimmune and infectious etiologies showed negative results. CONCLUSIONS: Topical antiinflammatory drops, artificial tears, erythromycin ointment, and systemic steroids were an effective treatment for this bilateral blepharoconjunctivitis and EM-like presentation of SARS-CoV-2.

Acquired Brown syndrome following COVID-19 infection in a child.

Coronavirus disease 2019 (COVID-19) is a highly virulent multisystem disease caused by the SARS-CoV-2 virus. Symptoms of COVID-19 infection commonly include fever, malaise, cough, and shortness of breath. Numerous manifestations affecting nearly every organ system have been described. Ophthalmic manifestations, though rare, have been reported, including, most commonly, conjunctivitis in both adults and children, which often occurs as part of a multisystem inflammatory syndrome in children. However, pediatric ocular findings of COVID-19 are poorly understood. We present a case of acquired Brown syndrome in a child following COVID-19 infection.

Clinical course, diagnosis, and management of bilateral COVID-19 associated conjunctivitis: A case study.

We present a rare case of COVID-19 associated conjunctivitis where patient presented with redness, foreign body sensation, watering, and pain. Symptoms started while patient was COVID-19 positive. On examination, severe conjunctival congestion was present along with follicles. Visual acuity was 6/6 in both eyes. The patient was started on topical antibiotics and showed improvement but again presented with aggravated symptoms. Conjunctival swab was sent for culture and sensitivity, which was negative for any organisms. The patient was then started on oral and topical steroid, which showed improvement. Even though COVID-19 associated conjunctivitis is self-limiting, here it showed a progressive course and resolved only after steroid.

[Viral conjunctivitis as the first sign of COVID-19 infection (clinical observation)]. / Virusnyi kon"yunktivit kak pervyi priznak koronavirusnoi infektsii COVID-19 (klinicheskoe nablyudenie).

The article presents a case of complicated viral conjunctivitis. Conjunctivitis was the initial sign of the new coronavirus infection (COVID-19) in the patient. The disease had a fairly long course and led to symmetrical scarring in the form of partial external symblepharon and dry eye syndrome. Ophthalmologists should be aware about this disease and its complications. Early treatment with corticosteroids in combination with symptomatic therapy can contribute to prevention of the development of conjunctival scarring. In addition to conjunctival scarring, this disease can possibly potentiate the development of keratitis, optic neuritis, and uveitis.

Association of Public Health Measures During the COVID-19 Pandemic With the Incidence of Infectious Conjunctivitis.

Importance: Infectious conjunctivitis is highly transmissible and a public health concern. While mitigation strategies have been successful on a local level, population-wide decreases in spread are rare. Objective: To evaluate whether internet search interest and emergency department visits for infectious conjunctivitis were associated with public health interventions adopted during the COVID-19 pandemic. Design, Setting, and Participants: Internet search data from the US and emergency department data from a single academic center in the US were used in this study. Publicly available smartphone mobility data were temporally aligned to quantify social distancing. Internet search term trends for nonallergic conjunctivitis, corneal abrasions, and posterior vitreous detachments were obtained. Additionally, all patients who presented to a single emergency department from February 2015 to February 2021 were included in a review. Physician notes for emergency department visits at a single academic center with the same diagnoses were extracted. Causal inference was performed using a bayesian structural time-series model. Data were compared from before and after April 2020, when the US Centers for Disease Control and Prevention recommended members of the public wear masks, stay at least 6 feet from others who did not reside in the same home, avoid crowds, and quarantine if experiencing flulike symptoms or exposure to persons with COVID-19 symptoms. Exposures: Symptoms of or interest in conjunctivitis in the context of the COVID-19 pandemic. Main Outcome and Measures: The hypothesis was that there would be a decrease in internet search interest and emergency department visits for infectious conjunctivitis after the adaptation of public health measures targeted to curb COVID-19. Results: A total of 1156 emergency department encounters with a diagnosis of conjunctivitis were noted from January 2015 to February 2021. Emergency department encounters for nonallergic conjunctivitis decreased by 37.3% (95% CI, -12.9% to -60.6%; P < .001). In contrast, encounters for corneal abrasion (1.1% [95% CI, -29.3% to 29.1%]; P = .47) and posterior vitreous detachments (7.9% [95% CI, -46.9% to 66.6%]; P = .39) remained stable after adjusting for total emergency department encounters. Search interest in conjunctivitis decreased by 34.2% (95% CI, -30.6% to -37.6%; P < .001) after widespread implementation of public health interventions to mitigate COVID-19. Conclusions and Relevance: Public health interventions, such as social distancing, increased emphasis on hygiene, and travel restrictions during the COVID-19 pandemic, were associated with decreased search interest in nonallergic conjunctivitis and conjunctivitis-associated emergency department encounters. Mobility data may provide novel metrics of social distancing. These data provide evidence of a sustained population-wide decrease in infectious conjunctivitis.

[COVID-19: is transmission through eye contact possible?] / COVID-19: vozmozhen li put' peredachi cherez glaza?

The article reviews international and Russian scientific papers concerning the possibility of transmitting coronavirus infections, particularly the COVID-19, through eye surface. According to the studied literature, the incidence of ocular symptoms in COVID-19 is around 0.8-31.6%, with conjunctivitis being the most frequent manifestation. The review summarizes data on virus detection in conjunctival discharge of COVID-19 patients. Across six studies, the total number of patients is 252, among which were 8 cases (3.17%) of virus detection in the conjunctival cavity. The review discusses the reasons for infrequent detection of the virus in the lacrimal fluid. The analyzed data shows that COVID-19 associated conjunctivitis can be the first symptom, the primary manifestation, or sometimes be detected in the lacrimal fluid of patients without any concomitant signs of eye surface inflammation. The article also presents two clinical cases of patients with keratoconjunctivitis and conjunctivitis associated with COVID-19, as well as the results of experimental transconjunctival and respiratory exposure of Rhesus macaques to SARS-CoV-2 with conclusion of possibility of this type of transmission. Additionally, the review contains the opinion of researchers concerning the influence of several factors on the possibility of virus detection in the lacrimal fluid. The conclusion was made that there is possibility of COVID-19 transmission through the eye surface. While it is not being considered a major transmission route, it should not be ignored. Conjunctival cavity of COVID-19 patients can be the source of infection. Eye protection measures should be undertaken when working with potentially infected patients.

Ocular Involvement in COVID-19: Conjunctivitis and More. / Okuläre Mitbeteiligung bei COVID-19: Konjunktivitis und mehr.

Since the beginning of 2020, SARS-CoV-2, the pathogen of COVID-19, has led to a global pandemic that also affects ophthalmology. Ophthalmologists can be confronted at any time with potentially COVID-19 associated ocular symptoms or manifestations in patients and also become infected through close patient contact. Even without systemic infection, the ocular surface can come into direct contact with aerosols or liquids containing SARS-CoV-2 particles. A smear infection through hand-to-eye contact is also possible. A purely isolated ocular infection has not yet been shown. Rather, it seems that ocular complications occur in the context of a systemic infection. However, ocular symptoms can also be the first symptom of COVID-19. The most common ocular complication of COVID-19 is mild follicular conjunctivitis. Haemorrhagic conjunctivitis, dry eye disease, episcleritis, or retinal involvement can also occur less frequently. There are currently no evidence-based therapy recommendations for COVID-19 associated diseases of the ocular surface. Artificial tears might be helpful for symptom relief. There is no evidence for antiviral, antibiotic, or anti-inflammatory therapies, but these medications might be used in individual cases. Potential intraocular complications include retinal artery occlusions and haemorrhages, as well as cotton wool spots caused by complement-mediated thrombotic angiopathy. Neuro-ophthalmological complications including Miller-Fisher syndrome or infarct-related central blindness can also occur in very rare cases. Knowledge of potential transmission routes and personal protective equipment is just as essential for each ophthalmologist as a basic knowledge of potential ocular symptoms and complications.

An Update on COVID-19 Related Ophthalmic Manifestations.

Purpose: To summarize ophthalmic manifestations of coronavirus disease (COVID-19) reported in the literature thus far.Methods: The PubMed database was systematically searched through October 24, 2020, to identify relevant articles using the following search terms: ("COVID-19" OR "SARS-CoV-2") AND ("eye" OR "ophthalmology" OR "retina" OR "retinal findings" OR "cornea" OR "conjunctiva"). Only articles published in English were included in this review.Results: The reported prevalence of ophthalmic manifestations is generally low, but correlates positively with the severity of the disease. Most commonly reported ocular manifestations are conjunctivitis, conjunctival hyperemia and chemosis. Retinal findings include microhemorrhages and flame-shaped hemorrhages, cotton wool spots, dilated veins, and tortuous vessels.Conclusion: Considering the COVID-19 cases have reached pandemic dimensions and are surging, yet again, it is of utmost importance to determine its ophthalmic manifestations and prevent their vision threatening complications. Further studies are warranted to establish whether the retinal findings appear due to the COVID-19 or are an incidental finding in patients with a preexisting diabetic or hypertensive retinopathy.

Evaluation of Nasopharyngeal and Conjunctival Swab Samples of Hospitalised Patients with Confirmed COVID-19.

PURPOSE: To evaluate the results of conjunctival and nasopharyngeal swab tests in patients with confirmed COVID-19. METHODS: This prospective study included 45 patients who were hospitalized for confirmed COVID-19. Nasopharyngeal swab samples were obtained from the patients before hospitalization. Only one eye of each patient was randomly selected for-conjunctival sampling. All participants underwent a complete slit-lamp examination. Conjunctival and nasopharyngeal swab samples were analyzed by reversetranscriptase-polymerase-chain reaction (RT-PCR). RESULTS: Twenty seven (60%) of the patients were male and 18 (40%) were female. Conjunctival swab was positive in only one (2.22%) patient. None of the COVID-19 patients showed ocular changes and symptoms. There were no abnormalities of the ocular surface, anterior chamber or posterior segment at slit-lamp examination. CONCLUSIONS: The RT-PCR was not high positive in the conjunctiva as in nasopharyngeal swabs. Ocular changes were not common in COVID-19 patients.

Covid-19 and acute conjunctivitis: Controversial data from a tertiary refferral Italian center.

PURPOSE: Although acute conjunctivitis has been listed from the beginning as a possible sign of COVID-19, the likelihood of this association remains unclear. The aim of this study was to investigate the relationship between COVID-19 and conjunctivitis. METHODS: In this retrospective, observational study, we recruited all patients with signs and symptoms of acute conjunctivitis seen at the Eye Emergency Department (ED), Turin Eye Hospital, between 01/01/2020 and 12/05/2020 and cross-checked our data with the Piedmont Region online COVID-19 registry in the same period. RESULTS: Among 10,065 patients seen at our ED during the timespan considered, 88 underwent a nasopharyngeal swab (NS) for SARS-CoV-2 detection within 4 weeks before/after our examination. On average, NS was performed -0.72 ± 1.8 weeks before/after eye examination. Of the 77 patients with a negative NS, 26 (33.8%) had a diagnosis of acute conjunctivitis, whereas the remaining 51 (66.2%) had other eye disorders. Among the 11 patients with COVID-19, 7 (63,6%) had a diagnosis of acute conjunctivitis. We found a non-statistically significant increase in NS positivity rate (21.2%) among cases examined at our ED for acute conjunctivitis, compared to the NS positivity rate (7.3%) in patients examined for all other eye conditions (p = 0.092). The Odds Ratio of having a positive NS in patients with acute conjunctivitis was 3.43 (95% I.C. = 0.9-12.8, p = 0.06). Considering online-registry data of Turin population during the same time-span, among 2441 positive NS cases only 27 (1.1%) presented with acute conjunctivitis. CONCLUSION: Our results do not reveal a statistically significant correlation between COVID-19 and acute conjunctivitis. SYNOPSIS: The present study analyzes retrospectively data from a tertiary eye referral center to investigate the relationship between COVID-19 infection and conjunctivitis.
