Abstract |
PURPOSE To compare the changes in subfoveal choroidal thickness between intravitreal aflibercept and ranibizumab injection in wet age-related macular degeneration (AMD). METHODS: Fifty patients with wet AMD patients who were treated with aflibercpet or ranibizumab were evaluated retrospectively. All patients were treated with pro re nata after 3 consecutive monthly injections and were followed up for at least 6 months. We measured subfoveal choroidal thickness (SFCT) using enhanced depth imaging spectral-domain optical coherence tomography before the first injection and 1, 2, 3, and 6 months after initial injection. RESULTS: The SFCT measures before initial injection and 1, 2, 3, and 6 months after initial injection were 244.94 ± 103.77 µm, 219.04 ± 95.89 µm, 208.74 ± 91.03 µm, 203.64 ± 91.35 µm, and 226.98 ± 96.79 µm in the aflibercept group (25 eyes) and 222.68 ± 102.04 µm, 210.23 ± 95.91 µm, 203.66 ± 99.39 µm, 197.27 ± 100.25 µm, and 210.32 ± 111.86 µm in the ranibizumab group (28 eyes). Mean change in SFCT was greater in the aflibercept group at 1 month, 2 months, and 3 months after initial injection (p < 0.05), but there was no significant difference in the mean change in SFCT between the two groups at 6 months after initial injection (p > 0.05). CONCLUSIONS: The decrease in SFCT was greater after aflibercept injection than ranibizumab injection in 3 consecutive months. However, at 6 months after initial injection, the difference in the change in SFCT was not significant. |
