Pharyngoconjunctival fever (PCF), caused by adenovirus strains 3, 4 and 7, most commonly affects children. There are reports in which conjunctivitis was the only sign of COVID-19. The term conjunctivitisrefers to inflammation of the conjunctiva; associated corneal involvement gives rise to keratoconjunctivitis and eyelid involvement suggests blepharoconjunctivitis. [19] It is recommended that two consecutive negative RT-PCR tests results are required before a patient can be considered safe.[20]. Ann Intern Med 2020;172(9):577-582, Santarpia JL, Rivera DN, Herrera V, Morwitzer MJ, Creager H, Santarpia GW, et al. Lu R, Zhao X, Li J, et al. [12], Conjunctivitis and keratitis are the only reported ocular signs of COVID-19 to date. It is an enveloped single-stranded RNA virus, which is closely related to the severe acute respiratory syndrome coronavirus. However, the following complications may occur; punctate keratitis with subepithelial infiltrates, bacterial superinfection, conjunctival scarring and symblepharon, severe dry eye, irregular astigmatism, corneal ulceration, and corneal scarring. • Treatment similar as EKC 9. Patients with red-eye must be inquired about recent traveling, cough, flu-like symptoms, fever, and history of similar symptoms in close contacts or recent contact with COVID-19 suspected or diagnosed cases. Zhou F, Yu T, Du R, Fan G, Liu Y, Liu Z, et al. However, important causes from a never-ending list of red-eye include; Adenoviral, Bacterial, Allergic conjunctivitis, Herpes simplex virus keratitis, Anterior uveitis, Foreign body, Corneal abrasion, Dry eye syndrome, Exposure keratopathy, and Chemosis. The pathophysiology of SARS-CoV2 related conjunctivitis is not completely understood. Several vaccines are in progress as well. [13], COVID-19 conjunctivitis starts as unilateral redness of eye with follicular reaction (inferior palpebral) like any other viral conjunctivitis. Red Eye Gone (Adeno) Viral When you see follicular conjunctivitis, adenovirus should be near the top of your diagnosis list. Lymphopenia, elevated aminotransaminase levels, elevated lactate dehydrogenase levels and elevated inflammatory markers (eg, ferritin, C-reactive protein, and erythrocyte sedimentation rate) have been reported in hospitalized patients with COVID-19. Patients with COVID-19 can have symptoms of watering, foreign body sensation, and red-eye, or they may be asymptomatic. After 10 or 15 days the communicability is almost zero.2 The incubation period of the virus is 5-12 days and people suffering from it can have a fever for up to ten days. [14]It may resolve by itself or progress to involve coarse epithelial keratitis, pseudomembranous conjunctivitis and bilateral hemorrhagic, pseudomembranous conjunctivitis or pseudodendritic keratitis. Having contact with infectious tears, eye discharge, fecal matter, … Viral conjunctivitis is an infection of the eye in which one or both eyes become red and uncomfortable. Minimum examination protocol that can help in diagnosis and management and avoiding additional clinical tests and investigations unless necessary. It is preferable to use disposable devices. Use of proper slit lamp shields and their regular disinfection after every patient. Conjunctivitis can be classified as infectious or non-infectious, and as acute, chronic, or recurrent. doi:10.1080/09273948.2020.1738501. 2020;28(3):391‐395. Approximately 97% of patients develop symptoms within 11.5 days of exposure. Conclusion: SARS-CoV-2 may cause ocular manifestations such as viral conjunctivitis. Wölfel  R, Corman  VM, Guggemos  W,  et al. Most cases resolve spontaneously. Infection is self-limited, but severe cases sometimes require topical corticosteroids. Chronic irritation may be caused by dust, pollens, or allergens etc. Although fever is a common symptom there are reports of afebrile COVID patients as well. It is not yet confirmed whether the disease started from bats or not. [5]ACE2 receptors were found in conjunctiva and cornea, although the receptor density in ocular tissues was lower. Currently, data to propose or oppose a therapy is insufficient. Because viral shedding can be prolonged (up to 37 days in one study), repeat testing (RT-PCR performed on a nasopharyngeal swab) is recommended for patients prior to treatment if less than 6 weeks from COVID-19 diagnosis, except in emergent circumstances. False-negative results are common because of the timing of sampling. Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study. Positive clinical findings on physical examination of the patients with COVID-19 include; fever, cough, shortness of breath, myalgias, sore throat, headache, rhinorrhea, new-onset loss of taste or smell and chest pain. On rare occasions, a Chlamydia infection is responsible for follicular conjunctivitis, especially in neonatal practice, when a baby gets it while passing through the … Viral follicular conjunctivitis: Multiple pale swellings in the lower fornix due to follicles which represent clusters of lymphocytes and plasma cells. Neisseria infection should be suspected when severe, bilateral, purulent conjunctivitis is present in a se… In terms of treatment, antibiotics are ineffective against viruses and there is no effective anti-viral drug. Herpes simplex infection can also cause keratitis, blepharitis, and iritis. Tonometer should be sterilized using a 10% diluted sodium hypochlorite solution. The affected child generally presents with red, profusely watery eyes and a palpable preauricular lymph node. When small blood vessels in the conjunctiva become inflamed, they're more visible. 3.Pharyngoconjunctival Fever (PCF) • adenoviral infection commonly associated with subtypes 3 & 7. The most common type of viral conjunctivitis is adenoviral conjunctivitis (see Figs. Virological assessment of hospitalized patients with COVID-2019. Doi:10.1056/NEJMoa2002032. Follicular conjunctivitis is one of those topics that always seems to pop up on exams. Hui KPY, et al. Phylogenetic analysis showed that there are more than 100 strains of SARS-CoV-2 with two different types; type L and type S. The receptor-binding region of SARS-CoV-2 is also similar to SARS-CoV. Symptoms: hyperemia, chemosis, watery discharge, photophobia and periorbital pain. Diagnosis is clinical; sometimes viral cultures or immunodiagnostic testing is indicated. Systemic complications include; acute respiratory distress syndrome, pneumonia, stroke, acute cardiac injury, cardiomyopathy, renal failure, and encephalopathy. Use of topical anesthesia may also alter the results.[18]. Cheema M, Aghazadeh H, Nazarali S, et al. Zhou P, Yang XL, Wang XG, et al. It can develop through exposure to the coughing or sneezing of someone with an upper respiratory tract infection. Pre-appointment screening of the patient. As the follicles become more and more enlarged, the raised follicles themselves can cause further irritation to the eye, creating a … COVID conjunctivitis resolves by itself without any morbidity if systemic complications do not occur. For systemic investigations, nasopharyngeal, throat, upper respiratory, and saliva swabs are taken for RT-PCR. 2020; 581:465–469.Doi:10.1038/s41586-020-2196-x. Animal studies have shown anterior uveitis, retinitis, vasculitis, and optic neuritis, as well.[17]. The conjunctiva is a fine, transparent layer of tissue that borders the inner eyelid surface and spans the sclera, or the white ocular surface. 10 COVID-19 conjunctivitis starts as unilateral redness of eye with follicular reaction (inferior palpebral) like any other viral conjunctivitis. Implementation of telemedicine wherever possible. Kids attending summer camps often pass it around, and it is especially rampant during the spring and fall seasons in schools. Another recent study showed that patients with COVID-19 who were treated with a combination of lopinavir, ritonavir, ribavirin, and interferon-beta-1b became PCR negative more quickly than those treated with lopinavir and ritonavir (control group). [10]Conjunctival infection can be due to direct inoculation of the ocular tissues from droplets of an infected patient, from nasopharynx by nasolacrimal duct or from the lacrimal glands. It is often spread by kids swi… It may resolve by itself or progress to involve coarse epithelial keratitis, pseudomembranous conjunctivitis and bilateral hemorrhagic, pseudomembranous conjunctivitis or pseudodendritic keratitis. Acute follicular conjunctivitis is usually associated with viral (epidemic keratoconjunctivitis, Herpes zoster keratoconjunctivitis, infectious mononucleosis, Epstein-Barr virus infection) or chlamydial infections (Inclusion conjunctivitis), while chronic disease may be caused by chronic chlamydial infection (trachoma, lymphogranuloma venereum) or as a toxic or reactive inflammaytroy response to topical medications and molluscum contagiosum infection. This page was last modified on August 4, 2020, at 13:29. Genomic characterization and epidemiology of 2019 novel coronavirus: implications for virus origins and receptor binding.

A follicular reaction can occur in other causes of conjunctivitis including chlamydia, molluscum contagiosum and topical drug toxicity. Nature 2020; 579:270. Lancet Respiratory Med, published on line May 7, 2020. https://doi.org/10.1016/S2213-2600(20)30193-4.Accessed May 8, 2020. Keratoconjunctivitis is a group of inflammatory eye conditions involving the cornea and the conjunctiva. [6], Old age, living in a congested area, chronic lung diseases, comorbidities including immuno-compromised states, diabetes, obesity, chronic renal, and liver diseases are the risk factors for severe systemic disease. Viral conjunctivitis may be due to systemic or localised infection. In those cases, a chronic follicular conjunctivitis is commonly seen, presumably related to the toxic effect of viral particles spilling onto the conjunctiva. Teoh, D. L., & Reynolds, S. (2003). COVID-19 started in December 2019 in Wuhan city of China and within no time evolved into the deadliest Pandemic of the present times. [1] [2] [3] However, there are reports of conjunctivitis associated with COVID-19.

The prevalence of conjunctivitis varies according to the underlying cause, which may be infl… Differential diagnosis of COVID conjunctivitis includes all causes of red-eye as there are cases of COVID conjunctivitis, which were otherwise systemically asymptomatic. Remedisivir is currently approved by the FDA for the treatment of suspected or laboratory-confirmed COVID-19 in adults and children hospitalized with severe disease. In children pharyngoconjunctival fever (PCF) due to HAdV types 3, 4, and 7 results in acute follicular conjunctivitis with fever, pharyngitis, periauricular lymphadenopathy. WHAT SHOULD BE DONE? However, in some cases, viral conjunctivitis can take 2 to 3 weeks or more to clear up. [reference needed]. This page has been accessed 12,257 times. [published online ahead of print, 2020 Apr 2]. Belser JA, Rota PA, Tumpey TM. However, the current wild spread is due to human-to-human transmission through droplets and direct contact with the mucous membranes including eyes, nose, or mouth. Ointments may be used to treat follicular conjunctivitis. Most viruses that cause conjunctivitis spread through hand-to-eye contact by hands or objects that are contaminated with the infectious virus. 2020;S0008-4182(20)30305-7. doi:10.1016/j.jcjo.2020.03.003. Conjunctivitis refers to any inflammatory condition of the membrane that lines the eyelids and covers the exposed surface of the sclera. Li Wenliang, the whistleblower of the disease, contracted this virus from an asymptomatic glaucoma patient. Keratoconjunctivitis as the initial medical presentation of the novel coronavirus disease 2019 (COVID-19). Can J Ophthalmol. Because questions can be asked about the pathology and differential diagnosis, this is a topic that probably should be very familiar to you. It's not uncommon for a viral illnesses to show up in the eyes. Viral Conjunctivitis Most cases of viral conjunctivitis are mild. Allergies, viruses, and bacteria are among the causes. Ocular tropism of respiratory viruses. Viral conjunctivitis and allergic conjunctivitis often cause lids to be matted shut on waking, due to drying of tears and serous secretions. It is highly infectious and care needs to be taken to prevent others from becoming infected, for example by not sharing towels.

For entry into the cell, the virus uses angiotensin-converting enzyme 2 receptor (ACE2). Plasma from recovered patients is also in the trial. Follicular reactions can be described as multiple, slightly ele- vated lesions with the appearance of rice grains and most evi- dent in the fornices (see Figure 1). Usual care involves the control of symptoms using cool compresses applied to the closed eyes, couple… Algorithm for the Evaluation of the Red Eye 6. ... All cause a follicular conjunctivitis but there are two distinct types of presentation: Pharyngoconjunctival fever: this is the more common form and tends to be mild. Once the diagnosis is made, the patient should be quarantined and closely followed for the development of complications. Different causes may give rise to the eye conduction, including viruses, atypical bacteria, and toxins. However, if we consider SARS-CoV model, the disease occurs in three stages; viral replication followed by immune hyperactivity and then tissue destruction. Clinical diagnosis is through a high level of suspicion, The tear sample collection varies from the use of Schirmer strips to conjunctival swabs. Definitive treatment is removal of the offending lesion (s), either by excision or curettage. However, a positive IgG test alone does not mean the patient is no longer contagious or is immune. Wearing of masks all the time by the patients, attendants, and the health care personnel. This supported the 14-day quarantine recommendations. Nalla  AK, Casto  AM, Huang  MW,  et al. Infect. It has an acute onset, initially unilateral with the second eye becoming involved in a week. Acute follicular conjunctivitis is usually associated with viral (epidemic keratoconjunctivitis, Herpes zoster keratoconjunctivitis, infectious mononucleosis, Epstein-Barr virus infection) or chlamydial infections (Inclusion conjunctivitis), while chronic disease may be caused by chronic chlamydial infection (trachoma, lymphogranuloma venereum) or as a toxic or reactive inflammaytroy response to topical … Earlier diseases related to Coronavirus were severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Serology and RT-PCR are the most common laboratory tests being performed. A condition caused by a virus, pharyngoconjunctival fever is highly contagious, especially during the first few days. Yuen KSC, Chan W-M, Fan DSP, et al. The condition is not normally serious and in most cases clears up without treatment. Immune stimulation causes the lymphoid follicles on the eye to become enlarged. Ocular screening in severe acute respiratory syndrome. Lancet 2020;395(10229): 1054-1062. Hung IF, Lung K, Tso EY, Liu R, Chung TW, Chu M, et al. Children between the ages of 5 and 18 are most susceptible to the condition. Avoiding air puff tonometer as it poses a danger of aerosol spread. This suggested that transmission of the virus may occur through the eyes. Viral conjunctivitis is a highly contagious acute conjunctival infection usually caused by adenovirus. Lancet 2020;395:565-574. Triple combination of interferon beta-1b, lopinavir–ritonavir, and ribavirin in the treatment of patients admitted to hospital with COVID-19: an open-label, randomised, phase 2 trial. [15] [16]It may also be associated with tender lymphadenopathy. Follicular conjunctivitis does not necessarily indicate an infectious process but in some cases it is secondary to bacterial or viral infections. There was initial data regarding the use of hydroxychloroquine, which later proved ineffective for COVID. The types of non-infectious conjunctivitis are allergic, mechanical/irritative/toxic, immune-medi… [7], The incubation period of COVID-19 is within 14 days with maximum numbers occurring within 4 to 5 days of exposure. 2. Marinho PM, Marcos AAA, Romano AC, Nascimento H, Belfort R. Jr. Retinal findings in patients with COVID-19. Doi: 10.1016/j.ajoc.2020.100735. Follicular conjunctivitis refers to the swelling or inflammation of the conjunctiva in the eye. Use of PPE with eye protection when it is necessary to examine a patient with respiratory symptoms. [9][9], Recently, viral RNA was detected in the samples collected from the rooms of COVID-19 patients admitted in the hospital, which further confirmed spread through direct contact with the surfaces contaminated with virus particles. Pink eye (conjunctivitis) is an inflammation or infection of the transparent membrane (conjunctiva) that lines your eyelid and covers the white part of your eyeball. Follicular conjunctivitis is the mildest form of a viral conjunctival infection. Ocul Immunol Inflamm. Emerg. Cell death results in the release of the virus into tears. Inflammation or infection of the conjunctiva is known as conjunctivitis and is characterized by dilatation of the conjunctival vessels, resulting in hyperemia and edema of the conjunctiva, typically with associated discharge. This article covers the diagnosis of the differing types of conjunctivitis. Comparative performance of SARS-CoV-2 detection assays using seven different primer/probe sets and one assay kit. If a patient is IgM positive and IgG negative, the patient is actively infected. The median time of virus shedding is 20 days with a maximum recorded time period of 37 days. Early after acquiring infection, antibodies to SARS-CoV-2 are detected in serum. Other reports showed that the patients of COVID-19 developed conjunctivitis later in their course of disease after hospitalization. [8][8] According to another study, the mean incubation period for SARS-CoV-2 was 5 to 7 days, and patients were typically infectious for several days prior to symptom onset. This page was enrolled in the International Ophthalmologists contest. 2020;395(10237):1610. doi: 10.1016/S0140-6736(20)31014-X.
