Background: Inflammatory adverse events following COVID-19 vaccination are being reported amidst the growing concerns regarding vaccine's immunogenicity and safety, especially in patients with pre-existing inflammatory conditions. Methods: Multinational case series of patients diagnosed with an ocular inflammatory event within 14 days following COVID-19 vaccination collected from 40 centres over a 3 month period in 2021. Results: Seventy patients presented with ocular inflammatory events within 14 days following COVID-19 vaccination. The mean age was 51 years (range, 19–84 years). The most common events were anterior uveitis (n = 41, 58.6%), followed by posterior uveitis (n = 9, 12.9%) and scleritis (n = 7, 10.0%). The mean time to event was 5 days and 6 days (range, 1–14 days) after the first and second dose of vaccine, respectively. Among all patients, 36 (54.1%) had a previous history of ocular inflammatory event. Most patients (n = 48, 68.6%) were managed with topical corticosteroids. Final vision was not affected in 65 (92.9%), whereas 2 (2.9%) and 3 (4.3%) had reduction in visual acuity reduced by ≤3 lines and > 3 lines, respectively. Reported complications included nummular corneal lesions (n = 1, 1.4%), cystoid macular oedema (n = 2, 2.9%) and macular scarring (n = 2, 2.9%). Conclusion: Ocular inflammatory events may occur after COVID-19 vaccination. The findings are based on a temporal association that does not prove causality. Even in the possibility of a causal association, most of the events were mild and had a good visual outcome. [ABSTRACT FROM AUTHOR]

Abstract Background  Etanercept is a tumor necrosis factor (TNF) inhibitor that has been licensed in the United States for the treatment of adult and juvenile rheumatoid arthritis as well as psoriatic arthritis. Reactivation of tuberculosis is a complication of its use. We report the first case of tuberculous uveitis due to etanercept. Methods  We performed a clinical chart review. Case  A 58-year-old Caucasian woman was referred to our hospital for chronic unilateral granulomatous panuveitis of the right eye (RE). She was on etanercept and methotrexate for rheumatoid arthritis. Since the patient was immunosuppressed with etanercept and since the uveitis was granulomatous we considered tuberculosis as a possible etiology. An aqueous humor tap was performed and sent for polymerase chain reaction analyses of Herpes simplex, Herpes zoster, and Mycobacterium tuberculosis (MT). This last test was positive. Another aqueous humor sample was taken and sent for microscopic examination of sputum for acid-fast bacilli and culture, both of which were positive for MT. A diagnosis of tuberculous uveitis was established; the patient was treated with rifampin, isoniazid pyrazinamide, and ethambutol and etanercept was stopped. Four months later there were no cells in the anterior chamber and the vitreous was clear. Discussion  To our knowledge this is the first reported case of tuberculous uveitis following treatment with etanercept. This etiology has to be considered in patients taking this drug who present with intraocular inflammation. [ABSTRACT FROM AUTHOR]
