Imaging of the Macula Indicates Early Completion of Structural Deficit in Autosomal-Dominant Optic Atrophy – Corrected Proof

Purpose: Optical coherence tomography (OCT) enables 3-dimensional imaging of the retina, including the layer of ganglion cells that supplies the optic nerve with its axons. We tested OCT as means of diagnosing and phenotyping autosomal-dominant optic atrophy (ADOA).Design: Cross-sectional study.Participants: The study included 49 patients with OPA1 exon 28 (2826delT) ADOA (age, 8.6–71.5 years; best-corrected visual acuity [BCVA], 20/700–20/20) and 51 mutation-free first-degree relatives as healthy controls (BCVA 20/25–20/10).Methods: Participants underwent routine examination, including automated perimetry, and OCT with segmentation of the perifoveal retinal ganglion cell–inner plexiform layer (GC-IPL) and the peripapillary retinal nerve fiber layer (RNFL).Main Outcome Measures: Perifoveal (Read more...)
