The position of this image on the retina (as defined by a specified nomenclature; the nomenclature is implicit in the code used).
Only a single Item is permitted in this Sequence.
Required if Ophthalmic Volumetric Properties Flag (0022,1622) is set to YES and Attributes Ophthalmic Anatomic Reference Point X-Coordinate (0022,1624) and Ophthalmic Anatomic Reference Point Y-Coordinate (0022,1626) do not contain a value. May be present otherwise.
Note
This Attribute is used to provide the user with a general reference point when viewing the image. If the implementation is able to identify a precise anatomic location, it will convey that information in Attributes Ophthalmic Anatomic Reference Point X-Coordinate (0022,1624) and Ophthalmic Anatomic Reference Point Y-Coordinate (0022,1626).
