Daneshvar R, et al. - In this observational cohort study, researchers tested the assumption that baseline optical coherence tomography (OCT) measures predict the progression of the visual field (VF) in a cohort of patients with suspected or established glaucoma and compare their performance with semiquantitative optic disc measures. The study sample consisted of 171 eyes of 95 patients with good-quality baseline retinal nerve fiber layer (RNFL) and macular OCT images and disc photographs with >2 years of follow-up and ≥5 VFs. In comparison to semi-quantitative optic disc measures, the baseline structural OCT measures anticipated subsequent VF progression. In prognostic models of glaucomatous VF deterioration, OCT-based structural measures should be included.
