Posterior eye shape measurement with retinal OCT compared to MRI [PDF]

open access: yes, 2016
PURPOSE. Posterior eye shape assessment by magnetic resonance imaging (MRI) is used to study myopia. We tested the hypothesis that optical coherence tomography (OCT), as an alternative, could measure posterior eye shape similarly to MRI. METHODS. Macular
