Abstract
We aimed to assess the subfoveal choroidal thickness (SFChT) and the effect of treatment with anti-vascular endothelial growth factor (anti-VEGF) agents on the SFChT in age-related macular degeneration (AMD) subtypes. We enrolled 128 eyes of 107 patients with neovascular AMD (60 women; 47 men; mean age, 73.6 ± 8.9 years), and prospectively evaluated the best-corrected visual acuity (BCVA) and SFChT at baseline and at 3, 6, and 12 months after treatment with anti-VEGF agents. Patients were assigned to the typical AMD, polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP) subgroups. In total, 85 (66.4%), 31 (24.2%), and 12 (9.4%) eyes were assigned to the typical AMD, PCV, and RAP subgroups, respectively. The baseline mean BCVA was 0.75 ± 0.26, 0.72 ± 0.21, and 0.77 ± 0.24 logMAR in the typical AMD, PCV, and RAP subgroups, respectively (p = 0.774). The mean baseline SFChT was 203.20 ± 35.80, 271.80 ± 24.50, and 182.93 ± 31.31 µm, respectively (p < 0.001). Mean SFChT significantly decreased from baseline to 3, 6, and 12 months after treatment. The RAP subtype presented a significantly higher decrease in SFChT compared to the other subtypes (p = 0.01). The percentage reduction in SFChT was not signifi...Continue Reading
