Purpose: To analyze the trend of COVID-19-related and non-COVID-19-related articles published in the Indian Journal of Ophthalmology (IJO) during the COVID-19 pandemic. Methods: A retrospective analysis of all COVID-19 and non-COVID-19-related articles published in all the issues of IJO from January 2020 to March 2021 was performed. The data were obtained from the official website of IJO, Editor IJO monthly email, and PubMed. The monthly data were analyzed and a comparative analysis was done. The articles were segregated as Original, Review, Case Report/Series, Letter to the Editor/Commentary, Guest Editorial, Research methodology, Point-Counterpoint, Consensus Criteria, Ophthalmic Images, Photo Essay, Surgical Techniques, and AIOS Meeting Papers. Results: Out of 1343 articles published in IJO during the pandemic, 182 (13.55%) were COVID-19-related and 1161 (86.45%) were non-COVID-19-related articles. Among COVID-19 articles (182), majority were letter to the editors 66 (36.26%), followed by original articles 39 (21.42%), commentaries 24 (13.18%), editorials 18 (9.89%), and preferred practices 13 (7.14%). The least were case reports five (2.74%), current ophthalmology and innovation three (1.64%) each, and one (0.54%) each of consensus criteria, images, and photo assays. In the non-COVID-19-related articles (1161), maximum were original articles 276 (23.77%), followed by case reports 179 (15.41%), photo assays 157 (13.52%), and commentaries 141 (12.14%). The least were three (0.25%) consensus criteria and two (0.17%) each of current ophthalmology and innovations. The lockdown issue with 223 articles, postlockdown phase 1 had 267, postlockdown phase 2 had 321, and postlockdown phase 3 with 316 (1127 articles) articles in IJO showed a rising trend in a number of published articles compared with the prelockdown issues (216 articles). Conclusion: The quality and quantity of articles published in IJO increased and improved significantly. The results were seen with progressive improvement in citations and impact factors of the journal.

Purpose Previous studies have highlighted the effectiveness of slit lamp shields in reducing aerosol spread. Our study investigated the optimal size and design for such shields. Methods Two sets of shields were made; each set included five cardboards of the following dimensions: 1 (44 × 52 cm), 2 (44 × 44 cm), 3 (22 × 52 cm), 4 (22 × 33.5 cm), and 5 (44 × 22.5 cm). Cardboards in set 1 were kept flat whereas those in set 2 were curved using plastic frames. Aerosol was generated at the patient's position using a water spray bottle, and aerosol levels were measured at the face position of the examiner and on the slit lamp table using two GP2Y1014AU0F sensors. The measurements were recorded in particles/0.01f 3 and analyzed using a Mann Whitney U test. Results Mean background indoor aerosol was 559. After aerosol generation, the level increased to a mean of 571 in the absence of any kind of shield but to a mean of 567 when shields were in place ( P < 0.05). Flat shield 1 provided the best protection against inhaled aerosol. Flat shield 2, despite its shorter height compared to shield 1, provided the best protection against precipitated aerosol on the table. Curving shield 5 significantly improved its protective properties against both inhaled and precipitated aerosol while keeping the short height that allowed better access during examinations. Conclusions Shields reduced aerosol spread with curved shields being more effective while creating fewer physical restrictions. GP2Y1014AU0F particle sensors are effective tools for quantifying aerosol spread. Translational Relevance An understanding of optimal slit lamp shield design will provide protection for examiners while facilitating effective examination.
