Definition of the location and extent of retinal detachment. The location was subdivided into superior, nasal, inferior, or temporal quadrants based on the imaginary lines centered on the optic nerve head (dotted lines). The extent was defined as the angular distance between lines connecting the optic nerve head center and the margins of detached retina (blue solid lines, angle α).
