Purpose:

To assess the influence of intravitreal anti-vascular endothelial growth factor (anti-VEGF) administration on vitreomacular interface- and retinal morphology in eyes with neovascular age-related macular degeneration (AMD) and to identify morphological markers potentially influencing disease prognosis.

Methods:

43 patients (51 eyes) with treatment naïve neovascular AMD subsequently treated with Bevacizumab 1.25mg (in 0.05ml of solution) were monitored until month 12 of follow-up. Following a loading dose of 3 monthly intravitreal anti-VEGF injections, patients were treated as-needed [pro re nata (PRN)]. Functional and morphological changes were assessed using Spectral Domain Optical Coherence Tomography (SD-OCT).

This retrospective study included 43 treatment-naive patients (51 eyes) with neovascular AMD over the course of 12 months. Patients were treated with a loading dose of 3 initial monthly anti-VEGF injections (Bevacizumab 1.25mg in 0.05ml of solution-Avastin®) and were followed monthly until year 1. Re-treatment was performed if needed (pro re nata-PRN) as previously reported.

Inclusion Criteria:

- diagnosis of treatment-naive neovascular AMD

Exclusion Criteria:

• any treatment with other anti-VEGF agents than Bevacizumab in the follow-up period
• any other diseases leading to macular edema
• prior vitrectomy
• uveitis
• retinal or corneal laser surgery
• high myopia (>6dpt)
• preceding eye trauma
