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.8.25.9-1AUTOREFRACTION 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.
>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 'Cylinder Sequence Macro' Table C.8.25.6.1-1
>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.
>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 'Cylinder Sequence Macro' Table C.8.25.6.1-1
>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.
