Purpose:
To discuss the ocular manifestations provoked by novel coronavirus 2019 (COVID-19) disease in humans, the natural history of the disease in the eye, and its treatment.
Methods:
We designed a narrative review of the ocular manifestations of COVID-19 based on the literature published till July 30, 2020. The databases were PubMed, Scopus, Cochrane Library, Google Scholar, and ScienceDirect. The inclusion criteria were (1) all types of clinical studies and (2) the topic was COVID-19 and its association to the eye regarding the current guidelines.
Results:
From 168 abstracts screened, 61 papers fully filled the inclusion criteria after the full-text screening. The 61 records include 13 case reports, 17 prospective (case series or cross-sectional) studies, 8 retrospective studies, 12 literature reviews (one systematic review), and 11 letters to the editor. The majority of the papers agreed that ophthalmic manifestations due to COVID-19 were few and rarely encountered. The main ocular pathology seemed to be conjunctivitis, where the viral polymerase chain reaction also happened to be most detectable. Posterior segment or neuro-ophthalmic manifestations were scarce. Viral genome detection in the eye as well as viral portal of entry to the globe is still vague.
Conclusion:
The exact incidence of ocular manifestations in COVID-19 disease is uncertain. Conjunctivitis is the most prevalent ocular manifestation. It is still a debate whether the eye is a portal of entry for infection.
Insights
Ocular manifestations of coronavirus disease 2019 (COVID-19) are uncommon, with conjunctivitis being the most frequent. The eye
Area of Science:
- Ophthalmology
- Infectious Diseases
- Virology
Background:
- The novel coronavirus 2019 (COVID-19) pandemic has raised concerns about potential ocular involvement.
- Understanding the spectrum of eye conditions associated with COVID-19 is crucial for clinical management.
Purpose of the Study:
- To review the ocular manifestations of COVID-19.
- To discuss the natural history and treatment of ocular COVID-19.
- To explore the eye as a potential route of viral entry.
Main Methods:
- A narrative review of literature published up to July 30, 2020.
- Searches conducted across PubMed, Scopus, Cochrane Library, Google Scholar, and ScienceDirect.
- Inclusion of all clinical study types associating COVID-19 with ocular findings.
Main Results:
- 61 papers met inclusion criteria from 168 screened abstracts.
- Ocular manifestations of COVID-19 are generally infrequent.
- Conjunctivitis was the most common ocular finding, with detectable viral RNA.
- Posterior segment and neuro-ophthalmic issues were rare.
Conclusions:
- The precise incidence of ocular symptoms in COVID-19 remains uncertain.
- Conjunctivitis is the most frequently reported ocular manifestation.
- The role of the eye as a portal of entry for SARS-CoV-2 is still under investigation.
