Purpose: To describe uveitis cases after the BNT162b2 mRNA SARS-CoV-2 vaccination.Methods: This is a multicenter, retrospective study. Vaccine-related uveitis diagnosis was supported by the classification of the World Health Organization Adverse Drug Terminology and the Naranjo criteria.Results: Twenty-one patients (23 eyes) with a mean age of 51.3 years (23-78 years) were included. Eight of the 21 patients had a known history of uveitis. The median time from previous to current attack was 1 year (0.5-15 years). There were 21 anterior uveitis cases, two with bilateral inflammation. Eight cases occurred after the first vaccination and 13 after the second vaccination. All but three presented as mild to moderate disease. Two patients developed multiple evanescent white dot syndrome after the second vaccination. The mean time from vaccination to uveitis onset was 7.5 ± 7.3 days (1-30 days). At final follow-up, complete resolution was achieved in all but two eyes, which showed significant improvement. One case of severe anterior uveitis developed vitritis and macular edema after the second vaccination, which completely resolved after an intravitreal dexamethasone injection.Conclusion: Uveitis may develop after the administration of the BNT162b2 mRNA vaccine. The most common complication was mild to moderate anterior uveitis, while multiple evanescent white dot syndrome can also occur less frequently.
FHC and IAU are two forms of anterior uveitis which are localized to the eyes with no evidence of systemic involvement. However, FHC has distinct clinical features and differs from IAU in that the inflammation is low grade, steroid non-responsive, and has a less aggressive clinical course. To try to dissect the mechanism for this difference the phenotypes of the cells in the AH and blood (PB) and the cytokines present in the AH in patients with FHC and IAU were compared. Three-colour flow cytometry was performed on the cells isolated from the AH and PB. Percentage of cells bearing the following markers were determined: CD3, CD4, CD8, CD4/CD25, CD8/CD25, CD19 and CD14. The cytokines IL-4, IL-10, IL-12 and interferon-gamma (IFN-gamma) were assayed by ELISA. In both groups T cell numbers were higher in the AH than PB, although the distribution of T cell subsets in PB was similar. In the AH, CD8+ T cell numbers were higher in FHC than in IAU (P = 0.003), whilst CD4+ numbers were higher in IAU than FHC (P = 0.01). AH cytokine profiles were different in the two groups: IFN-gamma levels were higher and IL-12 levels lower in the FHC group than IAU (P = 0.02), whilst IL-10 levels tended to be higher in the FHC group (P = 0.5). We suggest that different local mechanisms governing the balance of T cell/cytokine-mediated inflammation in the anterior segment may underlie clinical differences such as chronicity and response to steroids in these disorders.
Behçet's disease (BD) is an important cause of visual morbidity throughout the world, but shows striking differences in racial predilection. Despite important advances in the therapeutic management of acute intraocular inflammation, the long-term impact of these new strategies on visual outcome of BD and their efficacy in different ethnic groups is unknown. A comparative study of patient characteristics, clinical ocular features and inflammatory score, and current therapy was undertaken on all patients fulfilling the International Study Group criteria for Behçet's disease and the Behçet's Disease Research Committee of Japan, who attended the Uveitis Clinics of Moorfields Eye Hospital (n=19) and Kurume University School of Medicine (KUS) (n=35) during a continuous consecutive four-week period. Japanese patients were significantly older (43.2+/-11.8 years) than the patients seen in London (35.4+/-8. 9 years). There was a predominance of male patients in both groups. All patients seen in KUS were Japanese, while the patients in London included 12 Caucasians, five Middle Eastern, one African, and one Asian. No significant differences were seen between the two populations in the duration of systemic disease or systems affected by the disease, such as mouth ulcers, genital ulcers, skin lesions including erythema nodosum, or arthritis. The duration of ocular disease was similar in both centres: around seven years. There was, however, a significant difference in the number of eyes with active anterior uveitis (59.7% KUS vs 18.4% London (chi-square: 5.4; p=0.006)) and/or posterior uveitis (31.3% KUS vs 18.4% London (chi-square: 5.42; p<0.02)). No significant differences were found in the number of eyes with optic disc swelling or optic atrophy and in each centre the number of eyes with vision greater than 6/9 or worse than 6/60 were the same. The treatment schedules were very different between the two centres. More patients were treated with topical steroids in Japan (68.7% KUS vs 10.5% London (chi-square: 30.5; p=0.001), but a similar number used concomitant intraocular pressure-lowering agents. More patients received systemic steroids in London (84.2% London vs 17% KUS (chi-square: 20.25; p<0.001)). Three patients received systemic steroids alone, five had prednisolone and cyclosporin, four had prednisolone and azathioprine, and four had triple therapy with prednisolone, cyclosporin, and azathioprine. Only one patient used colchicine. Cyclosporin use was similar in London and KUS (47.4% and 42.8%, respectively). In Japan, three patients used prednisolone alone and three tacrolimus (FK506). In addition, two patients, who were on steroids alone, took colchicine as well. More patients in Japan had undergone surgery for cataract and glaucoma (chi-square: 4.0; p=0.045). In KUS, seven of 67 eyes had cataract surgery. A further three eyes had visually significant cataract and two eyes had undergone glaucoma surgery. In contrast, no patients in London had undergone any surgery up to and including this period.
