Research hot spots of ophthalmology-related coronavirus disease 2019 / 中华眼底病杂志

ABSTRACT

Objective:To study the research hot spots of ophthalmology-related coronavirus disease 2019 (COVID-19).Methods:PubMed database as the data source, the literatures of ophthalmology-related COVID-19 published on January 1, 2020 to February 22, 2022 were collected, limited to Medline included, the language type was limited to English and Chinese, and 1 592 literatures were included. By reading the titles and abstracts, the literatures of meeting notice, editor's note, etc. and the literature that was not quite relevant with ophthalmology-related COVID-19 were removed, and finally 1 547 literatures were included. Bibliographic Items Co-occurrence Matrix Builder (BICOMB 2.02 software) was used to collect the frequency of major Mesh terms/subheadings and the frequency of major Mesh terms after removing the subheadings, and the number of included articles published in the top 10 journals by the number of ophthalmology-related COVID-19 articles was recorded. VosViewer 1.6.18 software was used for cluster analysis of collaborator network and major Mesh terms, and the publication status and country or region distribution of active authors of ophthalmology-related COVID-19 were recorded.Results:Of the 1 547 literatures, the active authors were mainly from India, Italy, Singapore, Spain, and Hong Kong, China, and so on; the top 10 journals published 617 articles in total (39.88%, 617/1 547). The high frequency major Mesh terms/subheadings included COVID-19, viral pneumonia, coronavirus infection, eye diseases/epidemiology, complications, prevention & control, diagnosis, virology, and Severe acute respiratory syndrome coronavirus 2, betacoronavirus/isolation & purification, ophthalmology/education, organization & administration, telemedicine, delivery of health care/organization & administration, and mucormycosis/diagnosis, etc. After taking out the subheadings, the high frequency of major Mesh terms also included conjunctivitis, orbital disease, retinal diseases, neuromyelitis optica, retinal vein occlusion, myopia and other eye diseases, eye diseases-related systemic diseases, such as multiple sclerosis and Miller Fisher syndrome, therapy and prevention-related drugs, such as hydroxyl chloroquine, angiogenesis inhibitors, and vaccination.Conclusions:Ophthalmology-related COVID-19 researches have received extensive attention worldwide, COVID-19 is associated with multiple ocular diseases of anterior and posterior segments. COVID-19-related mucormycosis, hydroxychloroquine and possible retinal toxicity, and possible ocular adverse effects associated with vaccination are also noteworthy.
