Analysis of Short-Term Change in Subfoveal Choroidal Thickness in Eyes With Age-Related Macular Degeneration Using Optical Coherence Tomography

Abstract

BACKGROUND AND OBJECTIVE: To measure the subfoveal choroidal thickness in patients with age-related macular degeneration (AMD) over 6 months. PATIENTS AND METHODS: A retrospective, observational study of patients with AMD followed up for 6 months at the New England Eye Center. Baseline and 6-month follow-up subfoveal choroidal thickness was measured using spectral-domain OCT and compared. RESULTS: For the entire cohort, there was statistically significant thinning of the subfoveal choroidal thickness at 6 months compared to baseline that was driven by the cohort of patients with neovascular AMD (181.2 ± 75 μm to 173.4 ± 63 μm; P = .049). CONCLUSION: There was a statistically significant decrease in subfoveal choroidal thickness observed in this cohort of patients with AMD over 6 months, but it was driven by the subgroup of patients with neovascular age-related macular degeneration.
