Abstract
BACKGROUND: To evaluate the frequency and reason for retraction of ophthalmology publications. METHODS: Two independent reviewers retrieved data from PubMed and Medline using appropriate keywords. Statistical analysis was carried out using Mann-Whitney U test. A total of 83 articles were selected for the analysis between 1994 and 2019. Articles were retracted after a median of 1 year (IQR 4.0), and 55 (66.3%) articles were published in the year 2010 or after. RESULTS: Forty-eight (57.8%) articles were original articles. The most common subspecialties involved were basic science (51.8%), followed by vitreoretinal diseases (13.3%) and cornea and external diseases (7.1%). Fraudulent data were the cause of retraction in 22 (26.5%) articles, and 14 articles (16.87%) were retracted because of plagiarism. Thirteen articles (15.7%) were retracted due to errors in the data calculations, and ten (12.04%) were found to be duplicate submissions of previously published articles by the same author, while five articles (6.02%) had authorship disputes. Thirty-nine (46.9%) retracted articles were published in a journal with an impact factor greater than 2. The median number of citations received by the retracted articles was 2.0 (IQR 9.0). CONCLUSIONS: We conclude that the number of retractions in the ophthalmic literature have increased since 2010, though relatively limited information is available on the retracted articles. There is a need to strictly follow the current guidelines for providing the reasons for retraction and displaying retraction notices both in PubMed and on the journal websites.
