Shape of the Retinal Surface in Emmetropia and Myopia

purpose. To determine and compare the shapes of the retinas of emmetropic and myopic eyes. methods. Nonrotationally symmetrical ellipsoids were mathematically fitted to the retinal surfaces of 21 emmetropic and 66 myopic eyes (up to −12 D) of participants aged 18 to 36 years (mean, 25.5) using transverse axial and sagittal images derived from magnetic resonance imaging. results. The shapes of the ellipsoids varied considerably between subjects...
