Why is the visual field elliptical rather than circular?

Solution

Tthe visual field elliptical rather than circular because the magnitude of the misperception is significantly correlated with axial length,supporting anisotropic stretching models of myopic growth.Magnitude of the misperception is significantly correlated with axial length supporting anisotropic stretching models of myopic growth,the influence of retinal stretching on visual performance in myopic eyes depends critically on the nature of eye growth.

Finding dings in other studies have suggested that growth occurs primarily in an anisotropic manner, localized to the posterior pole. 411 12 13 Indeed, most pathologic funda Understanding the nature of ocular expansion has important implications for foveal and peripheral visual performance.
