Eye shape and retinal shape, and their relation to peripheral refraction [PDF]
, 2012 Purpose: We provide an account of the relationships between eye shape, retinal shape and peripheral refraction. Recent findings: We discuss how eye and retinal shapes may be described as conicoids, and we describe an axis and section reference system for
