Characteristics of retracted articles in ophthalmology

The retraction of publications is a crucial aspect of scientific integrity; it aims to correct the literature and alert scholars and the general public by identifying and labelling articles that contain erroneous data, unreliable findings, or flawed conclusions. Identifying and characterizing retracted articles within the scientific literature is thus very important. The aims of this article were to characterize retracted articles in the ophthalmological literature. One hundred and fifty-one retracted articles published between 1966 and 2023 were retrieved. The number of retracted articles showed an upward trend from 2020 onwards. Ocular oncology (n = 37, 24.5 %) was the most frequently represented subspeciality in the retracted articles, despite retina and uveitis being the most published. The most frequent reason for retraction was fake data (n = 62, 38 %). The labelling of retracted articles on some websites was unsatisfactory, especially on the free-access illegal platform Sci-Hub. On the other hand, platforms such as Dimensions, Scite and Retraction Watch exhibit promising accuracy. Improving the labelling of retractions is needed to reduce the citation of articles after they have been retracted. Solutions to reach this goal are discussed in this article. •The number of retracted articles in ophthalmology showed an upward trend from 2020 onwards.•Unexpectedly, retracted articles continue to be cited.•The identification of retracted articles on most online databases is inadequate.
