This report delineates primary diagnosis, indications for treatment, adverse events, and visual and anatomic outcomes after intravitreal brolucizumab.Methods: A retrospective review of a consecutive clinical case series of 110 eyes treated with intravitreal brolucizumab between January 1st and March 1st. 2020. All patients were included if they received intravitreal brolucizumab in an off-label delivery and had ongoing macular edema in the setting of prior, multiple intravitreal anti-VEGF and/or intravitreal triamcinolone acetonide. All patients had spectral domain OCT documented before, at the time of, and in serial follow-up after intravitreal brolucizumab.Results: Ninety-eight of 98 patients had marked decrease in macular edema. Indications for treatment were assigned to the primary etiologic diagnosis leading to the macular edema secondary to radiation retinopathy, complex epiretinal membrane, or complex diabetic retinopathy. In this series, sdOCT central point thickness decreased by an average of 71.5 microns, subretinal fluid resolved, and visual acuity was improved in 40% (greater than two Snellen lines) and stable in 60% (within two Snellen lines). No patient experienced a severe adverse event to specifically include vitritis and/or vasculitis.Conclusion: In this series, brolucizumab intravitreal injection was associated with significant improvement in macular edema in each diagnostic category. No serious complications to treatment were found in this series. Brolucizumab, though associated with known intraocular inflammation and vasculitis, demonstrated marked benefit in these complex eyes previously unresponsive to aggressive intravitreal pharmacotherapy.Keywords: brolucizumab, off-label usage, retinal vasculitis, vitreous inflammation, intraocular inflammation, macular edema |
