C.8.25.9 Autorefraction Measurements Module

Table C.8.25.9-1 defines the Attributes used to represent the refractive measurements by an autorefractor of a patient's eyes. Usually both eyes are measured, but sometimes just one.

Table C.8.25.9-1. Autorefraction Measurements Module Attributes

Attribute Name	Tag	Type	Attribute Description
Autorefraction Right Eye Sequence	(0046,0050)	1C	A Sequence that specifies refractive measurements of a patient's right eye. Only a single Item shall be included in this Sequence. Required if the right eye is measured. Note If Autorefraction Right Eye Sequence (0046,0050) is present, Measurement Laterality (0024,0113), if present, will have a value of R or B as appropriate.
>Sphere Power	(0046,0146)	1	Refractive power of the eye that is the same in all meridians, measured at distance (optical infinity), in diopters.
>Include Table C.8.25.6.1-1 “Cylinder Sequence Macro Attributes”
>Pupil Size	(0046,0044)	3	The horizontal diameter measurement of the pupil, in mm.
>Corneal Size	(0046,0046)	3	The horizontal diameter measurement of the cornea, in mm.
Autorefraction Left Eye Sequence	(0046,0052)	1C	A Sequence that specifies refractive measurements of a patient's left eye. Only a single Item shall be included in this Sequence. Required if the left eye is measured. Note If Autorefraction Left Eye Sequence (0046,0052) is present, Measurement Laterality (0024,0113), if present, will have a value of L or B as appropriate.
>Sphere Power	(0046,0146)	1	Refractive power of the eye that is the same in all meridians, measured at distance (optical infinity), in diopters.
>Include Table C.8.25.6.1-1 “Cylinder Sequence Macro Attributes”
>Pupil Size	(0046,0044)	3	The horizontal diameter measurement of the pupil, in mm.
>Corneal Size	(0046,0046)	3	The horizontal diameter measurement of the cornea, in mm.
Distance Pupillary Distance	(0046,0060)	3	Distance in mm between the pupils when the patient's object of regard is in the distance, as measured by an autorefractor.
Near Pupillary Distance	(0046,0062)	3	Distance in mm between the pupils when the patient's object of regard is at near, as measured by an autorefractor.
