Mechanisms of Cataract Formation in the Human Lens

Abstract

<h3>Background</h3> Brolucizumab has recently been approved in Europe as a novel treatment for patients with neovascular age-related macular degeneration (nAMD). We report on early experiences with real-world outcomes of switch to brolucizumab therapy in previously anti-vascular endothelial growth factor (anti-VEGF)-treated patients. <h3>Methods</h3> Patients with recalcitrant nAMD were switched to brolucizumab therapy. Functional and structural parameters 4 weeks after first brolucizumab injection were evaluated including best-corrected visual acuity (BCVA (logMAR)), foveal centre point (FCP (µm)), central subfield retinal thickness (CSRT (µm)) and macular volume (mm³). <h3>Results</h3> Sixty-three eyes of 57 patients with nAMD (52.6% females) with a mean (±SD) age of 79.5±6.7 years were included. Mean change of BCVA was −0.02±0.13 logMAR (p=0.322). Significant reductions were recorded for FCP with a mean (±SD) change of −66.79±72.64 µm, −66.76±60.71 µm for CSRT and −0.27±0.24 mm³ for macular volume (all p&lt;0.001). Intraocular inflammation was observed in seven eyes of seven patients, including one case of retinal vasculitis without occlusion. <h3>Conclusions</h3> The results of the SHIFT study indicate that switch to brolucizumab may represent a treatment option in patients with nAMD poorly responsive to other anti-VEGF agents. Further long-term analyses appear prudent to assess efficacy and safety of brolucizumab in a routine clinical setting.
