Abstract

Purpose To compare choroidal thickness in patients with intermediate or advanced age-related macular degeneration (AMD) and control subjects using enhanced-depth imaging optical coherence tomography (EDI-OCT). Design Retrospective cross-sectional study of 325 eyes from 164 subjects who underwent EDI-OCT for the Age-Related Eye Disease Study (AREDS) 2 Ancillary Spectral Domain OCT study. Methods Choroidal thickness was measured by semi-automated segmentation of EDI-OCT images from 1.5 mm nasal to 1.5 mm temporal to the fovea. Multivariate linear regression was used to evaluate the association of subfoveal choroidal thickness or average choroidal thickness across the central 3-mm segment with systemic and ocular variables. Choroidal thickness measurements were compared between eyes with no AMD (n = 154) (ie, controls), intermediate AMD (n = 109), and advanced AMD (n = 62). Results Both subfoveal and average choroidal thicknesses were associated with age (P <.001) and refractive error (P <.001), but not other variables tested. Mean average choroidal thickness was significantly reduced in advanced AMD as compared with control eyes (P =.008), with no significant difference between advanced and intermediate AMD eyes (P =.152) or between intermediate AMD and control eyes (P =.098). Choroidal thinning was also noted from 1.5 mm nasal to 1.5 mm temporal to the fovea when comparing advanced AMD with control eyes (P <.05 at all 0.5 mm interval locations). After adjustment for age and refractive error, however, there was no significant difference in subfoveal (P =.675) or average choroidal thickness (P =.746) across all 3 groups. Conclusions When adjusted for age and refractive error, central choroidal thickness may not be significantly influenced by AMD status based on AREDS categorization.
