Other reports showed that the patients of COVID-19 developed conjunctivitis later in their course of disease after hospitalization. Ointments may be used to treat follicular conjunctivitis. The risk factor for COVID conjunctivitis is direct contact with a person having COVID. For entry into the cell, the virus uses angiotensin-converting enzyme 2 receptor (ACE2). [11] Similar to lung tissue, cells in conjunctiva die either by viral-mediated lysis or by immune reactions. • Treatment similar as EKC 9. Lancet 2020;395:565-574. The pathophysiology of SARS-CoV2 related conjunctivitis is not completely understood. [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 highly infectious and care needs to be taken to prevent others from becoming infected, for example by not sharing towels. It can develop through exposure to the coughing or sneezing of someone with an upper respiratory tract infection. [13], COVID-19 conjunctivitis starts as unilateral redness of eye with follicular reaction (inferior palpebral) like any other viral conjunctivitis. [15] [16]It may also be associated with tender lymphadenopathy. ... 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. Emerg. Pharyngoconjunctival fever (PCF), caused by adenovirus strains 3, 4 and 7, most commonly affects children. [5]ACE2 receptors were found in conjunctiva and cornea, although the receptor density in ocular tissues was lower. Most viruses that cause conjunctivitis spread through hand-to-eye contact by hands or objects that are contaminated with the infectious virus. The term conjunctivitisrefers to inflammation of the conjunctiva; associated corneal involvement gives rise to keratoconjunctivitis and eyelid involvement suggests blepharoconjunctivitis.

This page was enrolled in the International Ophthalmologists contest. Viral conjunctivitis and allergic conjunctivitis often cause lids to be matted shut on waking, due to drying of tears and serous secretions. Different RNA gene targets are employed by different manufacturers. Use of PPE with eye protection when it is necessary to examine a patient with respiratory symptoms. COVID-19 conjunctivitis starts as unilateral redness of eye with follicular reaction (inferior palpebral) like any other viral conjunctivitis. [21] Both these studies suggest the positive role of antiviral therapy if given early in infection. A Review of Coronaviruses and Ocular Implications in Humans and Animals. Am J Ophthalmol 2004;137:773–4. A pneumonia outbreak associated with a new coronavirus of probable bat origin. If IgM and IgG are both positive, infection is recent and may or may not be active. The consequent non-specific acute follicular conjunctivitis is the most common type of viral conjunctivitis and usually results in mild ocular involvement with concurrent systemic findings, such as a sore throat or cold. It presents with a watery discharge, conjunctival redness, follicular reaction and a preauricular lymphadenopathy on the affected side. [19] It is recommended that two consecutive negative RT-PCR tests results are required before a patient can be considered safe.[20]. Microbiol Mol Biol Rev 2013;77:144–56.doi:10.1128/MMBR.00058-12.
