Ophthalmic Axial Length Measurements Length Summation Sequence Attribute

TypeConditionally Required (1C)
Value Multiplicity1
Value RepresentationSequence (SQ)

Axial length of a patient's eye, in mm, when it is calculated by summation of multiple segmental axial length measurements.

One or more Items shall be included in this Sequence.

Required if Ophthalmic Axial Length Measurements Type (0022,1010) is LENGTH SUMMATION.

See Section C. for further explanation.

Section C.

C. Ophthalmic Axial Length Measurements Segment Name Code Sequence

When the acquisition device type is ultrasound, the Ophthalmic Axial Length (0022,1019) may represent distance calculated using a single time value and an average presumed velocity for the entire eye. Alternatively it may represent the sum of multiple segmental axial length measurements with each distance value calculated using a different time value and a presumed velocity specific to that segment of the eye.

When the acquisition device type is optical, the whole length can be measured instead of measuring and summing up different segments of the eye. Nevertheless, optical axial measurement devices can also measure segments of the eye independently(e.g., the Anterior Chamber depth).

Each segment of the eye that is measured shall be identified by the Ophthalmic Axial Length Measurements Segment Name Code Sequence (0022,1101).
