International audience. Purpose To describe the patient characteristics and clinical course of severe intraocular inflammation (IOI) following intravitreal injection (IVT) of faricimab. Design Retrospective case series. Methods Case series at a single French academic center (Dijon University Hospital) where 263 patients were treated with faricimab IVT between January 9, 2024 and May 7, 2024. Results Over the 4-month period, a total of 1659 eyes (1338 patients) received anti-vascular endothelial growth factor (anti-VEGF) IVTs for a total of 3510 IVTs, of which 343 eyes (263 patients) received faricimab IVTs for a total of 971 IVTs. Overall, six pretreated eyes with neovascular age-related macular degeneration that were switched to faricimab developed severe unilateral IOI following faricimab IVT (1/162 injections [0.62%]), including five patients presenting with a severe anterior and intermediate uveitis mimicking infectious endophthalmitis. All eyes were normotensive and presented with mild to moderate pain and predominantly moderate vitritis, associated with granulomatous keratic precipitates in two eyes and nonocclusive vasculitis in one eye. The clinical presentation, sterile vitreous sample culture, and rapid improvement with treatment made the diagnosis of infectious endophthalmitis unlikely. Four patients out of six did not recover their pre-IOI visual acuity, with an average visual loss of +0.2 logMAR. Two patients had positive antinuclear antibodies, including one with a history of cutaneous lupus. Conclusions In this case series, we reported six cases of severe IOI after intravitreal faricimab over 4 months in a single French center with an estimated incidence rate of 0.6% per injection. Future real-world data will contribute to a better evaluation of the epidemiology of this rare inflammatory adverse event related to intravitreal faricimab.
