Occlusive Retinal Vasculitis Following Intravitreal Brolucizumab

Open access

Abstract

Purpose: To analyze a case series of retinal vasculitis reported to the American Society of Retina Specialists (ASRS) following Food and Drug Administration approval of brolucizumab for treatment of neovascular age-related macular degeneration. Methods: The ASRS Research and Safety in Therapeutics Committee analyzed clinical and imaging characteristics from submitted reports of retinal vasculitis after brolucizumab. Results: Retinal vasculitis was reported in 26 eyes of 25 patients (22 [88%] female) after treatment with brolucizumab. Imaging studies were available for 24 of 26 eyes. Most cases (92%) were associated with intraocular inflammation, which presented at a mean of 25 days (range, 3-63 days) after the most recent brolucizumab injection. Mean visual acuity (VA) was 20/52 (range, 20/25-4/200) before the adverse event, 20/151 (range, 20/25-hand motion) at presentation of the adverse event, and 20/243 (range, 20/30-light perception) at last follow-up. Twelve eyes (46%) had a greater than 3-line decrease in VA at final follow-up, and 12 eyes (46%) had a final VA of 20/200 or worse. Analysis of retinal imaging identified vasculopathy that involved retinal arteries (91%), retinal veins (79%), and choroidal vessels (48%). Occlusive disease was apparent on imaging in 83% of eyes. Treatment approaches were varied. Conclusions: Retinal vasculitis has been identified in a series of eyes following brolucizumab. Although a few eyes in this series were asymptomatic or minimally symptomatic, some eyes had significant vision loss. A careful examination for signs of active inflammation prior to brolucizumab injection is recommended. Once vasculopathy is suspected, angiographic imaging may help define the spectrum of involvement. Optimal treatment strategies remain unknown.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Average time to presentation was 53 days after the last brolucizumab injection (range 8-137 days).

    “Average time to presentation was 53 days after the last brolucizumab injection (range 8–137 days).”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [37]

    The Results (Demographics; page not provided) report a mean time to presentation of 26 days after the most recent brolucizumab injection (range 3–63 days). The 53-day mean and 8–137-day range appear in Results (Outcomes), but measure time from the last injection to the most recent follow-up visit, not to presentation. (LLM, conf=0.94)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • The largest study outside of the clinical trials to date evaluating retinal vasculitis after brolucizumab is a retrospective analysis of 26 eyes from 25 patients that were reported to the ASRS.

    “The largest study outside of the clinical trials to date evaluating retinal vasculitis after brolucizumab is a retrospective analysis of 26 eyes from 25 patients that were reported to the ASRS [37].”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [37]

    The Methods and Results > Demographics sections describe an analysis of ASRS reports covering 26 eyes from 25 patients after brolucizumab treatment. The Conclusions > Epidemiology section mentions other case reports and series being collected, but does not establish that this was the largest study outside clinical trials to date. Page numbers are unavailable in our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The average time to presentation in recent case series has ranged from 30 to 53 days after injection.

    “The average time to presentation in recent case series has ranged from 30 to 53 days after injection [37, 38].”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [37]

    The Results > Demographics section reports a mean time to presentation of 46 days from the first brolucizumab injection, which falls within the claimed range. But it reports 26 days from the most recent injection, below the claimed 30-day lower bound. The 53 days in Results > Outcomes measures time to the most recent follow-up visit, not time to presentation; page numbers were not provided in our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Female predominance in brolucizumab-associated retinal vasculitis may point towards an auto-immune response.

    “The female predominance of brolucizumab-associated retinal vasculitis reported by Witkin et al. (22 of 25 patients were female) may point towards an auto-immune response, although no definitive correlation to auto-immune disease has been made [37].”

    From Mechanisms of sterile inflammation after intravitreal injection of antiangiogenic drugs: a narrative review (2021) · cites this paper as [37]

    Results > Demographics reports that 22 of 25 patients were women. Conclusions > Etiology considers a possible immune-mediated mechanism, but Conclusions > Epidemiology says the apparent sex disparity could be due to chance and does not link it to an autoimmune response; it also finds no indication of an association with autoimmune disease. Page numbers are not available in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Anterior chamber cell was present in 65% of eyes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
