Peripapillary Scleral Deformation and Retinal Nerve Fiber Damage in High Myopia Assessed With Swept-Source Optical Coherence Tomography – Corrected Proof
Purpose: To study peripapillary morphologic changes in highly myopic eyes using swept-source optical coherence tomography at a longer wavelength.Design: Prospective cross-sectional study.Methods: Peripapillary regions of 196 eyes of 107 patients with high myopia (refractive error, 26.0 mm) were analyzed quantitatively and qualitatively with an swept-source optical coherence tomography prototype system that uses a tunable laser light source operated at a 100,000-Hz A-scan repetition rate in the 1-μm wavelength region. The visual field was evaluated by standard automated perimetry. Area of peripapillary atrophy β and presence of scleral protrusion temporal to the optic disc were assessed.Results: peripapillary atrophy β area, but not (Read more...)
