Patient adherence to therapy after switch to aflibercept from bevacizumab or ranibizumab for treatment-refractory neovascular age-related macular degeneration.

Purpose: Clinical trials have demonstrated that switching patients from intravitreal bevacizumab (IVB) or ranibizumab (IVR) to aflibercept (IVA) for treatment-refractory neovascular age-related macular degeneration (nAMD) can decrease the injection frequency. This study evaluated whether there was a difference in the rate of injections or nonadherent events after switching therapies.

Methods: The study comprised a retrospective, cross-sectional analysis of patients treated for nAMD from 2010 to 2018 who received ≥3 intravitreal injections of IVB/IVR prior to switching to IVA because of treatment-refractory nAMD.

Intraocular pressure decreases in eyes with glaucoma-related diagnoses after conversion to aflibercept for treatment-resistant age-related macular degeneration.

Objective: To understand intraocular pressure (IOP) response after switching from intravitreal bevacizumab (IVB) and/or ranibizumab (IVR) to intravitreal aflibercept (IVA) for treatment-resistant neovascular age-related macular degeneration (nAMD) in patients with and without coexisting glaucoma-related diagnoses.

Methods: Retrospective, cross-sectional comparative case series of 62 eyes of 58 patients treated with intravitreal injection for nAMD from March 2010 to April 2018. Patients with glaucoma-related diagnoses, defined here as open-angle glaucoma or suspicion of open-angle glaucoma, ocular hypertension, and/or narrow-angle glaucoma, were compared to those without glaucoma.
