Article Abstract

Purpose: To assess how transitioning from an Aflibercept to a Faricimab intravitreal treatment impacts retinal structures and functional aspects in patients with neovascular age related macular degeneration (nAMD) in a real-life setting.

Patients And Methods: A retrospective clinical study including 49 patients (57 eyes) with nAMD at the Department of Ophthalmology and Optometry, Kepler University Hospital, Linz, Austria was performed. The patients, who had previously been receiving monthly Aflibercept injections with an unsatisfactory treatment response, were switched to intravitreal Faricimab and followed-up between 12/2022 and 12/2023.

Results: The mean treatment-interval before the fifth injection with Faricimab was 5.35 ± 1.49 weeks and was therefore significantly longer compared to the monthly interval with Aflibercept (. Mean baseline central retinal thickness (CRT) was 267.82 ± 76.00 µm and decreased significantly already at month 1 to 249.61 ± 65.35 µm (). After the fourth intravitreal injection, there was no significant change with a CRT of 252.95 ± 56.96 µm (.134). There was a significant reduction in the number of patients showing subretinal fluid (SRF) and intraretinal fluid (IRF). In eyes with fibrovascular pigment epithelium detachment (PED), an interval extension was not possible in more than half of the cases. Eyes with serous and drusenoid PED and a rather high amount of hyper-reflective foci (HRF), the majority showed a significant response after the switch.

Conclusion: An initial loading dose could be beneficial to elongate Faricimab's additional effect of reducing retinal swelling in eyes with nAMD and previous low-response to Aflibercept. Serous and drusenoid PEDs seem to benefit more than fibrovascular PEDs. A high amount of intraretinal HRF in patients with PED was a sign for good respondence to Faricimab.

Purpose: To describe the clinical and multimodal imaging features of a novel form of macular neovascularization (MNV), designated Type 4 MNV, defined by mixed Type 1 and Type 2 neovascularization (NV), extensive intraretinal anastomotic NV, and central posterior hyaloid fibrosis (CPHF).

Methods: This multicenter retrospective observational case series included patients with neovascular age-related macular degeneration (AMD) exhibiting both Type 1 and 2 MNV and an overlying anastomotic intraretinal NV network. This was confirmed with OCT and OCT angiography (OCTA).

Purpose: To evaluate visual, anatomical and safety outcomes of aflibercept 8 mg in previously treated patients with neovascular age-related macular degeneration (nAMD).

Methods: This retrospective study included nAMD patients switched to aflibercept 8 mg from prior anti-VEGF therapies at Sahlgrenska University Hospital between February 2024 and February 2025. Data on best-corrected visual acuity (BCVA), central retinal thickness (CRT), pigment epithelial detachment (PED) height, fluid status, treatment intervals, time to fluid recurrence and adverse events were collected.

Purpose: To identify predictors of the 2-year best-corrected visual acuity (BCVA) after subretinal tissue plasminogen activator (tPA) injection for massive submacular hemorrhage (SMH) complicating neovascular age-related macular degeneration (nAMD).

Study Design: A prospective, observational study.

Methods: This study included consecutive eyes with massive SMH and nAMD that underwent vitrectomy with subretinal tPA injection and follow-up for 2 years.

Unlabelled: Automated analysis of optical coherence tomography (OCT) biomarkers improves the prediction of results of loading anti-VEGF therapy of vascular pigment epithelial detachment (PED) associated with neovascular age-related macular degeneration (nAMD).

Objective: This study evaluated the effectiveness of OCT biomarker analysis algorithm in predicting the anatomical outcomes of loading anti-VEGF therapy for vascular PED in nAMD.

Material And Methods: OCT scans performed prior to loading anti-VEGF therapy were analyzed using the algorithm in 69 treatment-naïve nAMD patients (70 eyes) with vascular PED exceeding 200 µm in height.
