Purpose: To investigate disorganization of retinal inner layers (DRIL) as a biomarker in eyes with diabetic macular oedema (DME) treated by intravitreal dexamethasone (DEX) implant.Methods: Multicentre, retrospective study including eyes with DME treated with DEX implant and follow‐up of 12 months after the first injection. OCT scans were evaluated for the presence of DRIL and other structural features. Best corrected visual acuity (BCVA) and central subfield thickness (CST) were recorded at baseline and at 2, 4, 6 and 12 months after treatment. Correlation between DRIL at baseline and outcomes after DEX treatment and the change in DRIL were analysed.Results: A total of 177 eyes (177 patients; naïve, n = 131; refractory, n = 46) were included. Patients without DRIL at baseline gained significantly more vision and enjoyed greater reduction in CST over 12 months (both p = 0.03). DRIL at the boundary between the ganglion cell‐inner plexiform complex and inner nuclear layer improved in 48/64 eyes (75%, p < 0.001), while DRIL between the inner nuclear layer and outer plexiform layer improved in 27/77 eyes (35%, p = 0.004).Conclusions: This is the first study to show that DEX implant has the potential to ameliorate DRIL. Patients without DRIL at baseline have a favourable outcome. DRIL may serve a robust biomarker in DME treated by DEX implant.

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.
