ARCHETYPE IDopenEHR-EHR-OBSERVATION.exophthalmometry.v0
ConceptExophthalmometry
DescriptionMeasurement of eye globe position relative to the orbital rim to assess protrusion or retraction of the eyeball.
UseUse to record all measurements of eye globe position that include a measure of anterior-posterior position, regardless of the measurement method or device used.
MisuseNot to be used for measurements of orbital dimensions that do not relate to globe position relative to the orbital rim.
PurposeTo record measurements of eye globe position in relation to the orbital rim for assessment of exophthalmos or enophthalmos.

Provocative ManeuversProvocative Maneuvers:
  • Valsalva Maneuver [A maneuver by which exhalation is attempted against closed airways.]
Confounding FactorsConfounding Factors: Patient circumstances or actions which affect interpretation of the result. Often termed 'reliability' in opthalmological documentation. May include actions aiming improve the patient's ability to participate such as holding the lid open.
Examples: 'Patient was confused', "Lid held open by hand" "Excentric Fixation"
Choice of:
  •  Text
  •  Coded Text
    • Lid Swelling
    • Blepharospasm
    • Confusion
    • Excentric Fixation
    • Manually holding lid open
    • Uncooperative
    • Good cooperation
    • Lying in Bed
    • Lack of Fixation
data
ResultResult: The measurement of globe position in the anterior-posterior axis, the main measure of exomphthalmometry.
The landmarks compared along this axis may vary by method. For instance, in case of Hertel Exophthalmometry, it is the anterior-posterior distance between a line connecting the lateral orbital rims and the apex of the cornea. High values indicate Exophthalmus, low Values indicate Enophthalmus
Property: Length
Units: mm
Globe position in vertical axisGlobe position in vertical axis: A measure of the globe position in the vertical position.
The landmarks compared along this axis may vary by method, and it is not measured by all Exomphthalmometry devices. The most commonly used Exophthalmometer (Hertel) does not produce this value, but the Naugle Exophthalmometer does. Abnormal Values reflect hyper-ophthalmus or hypo-ophthalmus.
Eye examinedEye examined:
  • Right Eye [The right eye was examined.]

  • Left Eye [The left eye was examined.]

Comment
Interpretation
No test resultNo test result: No visual acuity test result is available for the test eye.
Record as True if the clinician was unable to record a result for the test eye.
Reason for no test resultReason for no test result: Reason why no visual acuity test result is available for the test eye.
For example, patient was not cooperative; patient was not capable; ran out of time.
protocol
Horizontal Base DistanceHorizontal Base Distance: The Horizontal distance between the reference points that are being compared to the globe position. In a Hertel exomphtalmometry, this refers to the distance between the lateral orbital rims.
Property: Length
Units: mm
Measurement Device TypeMeasurement Device Type:
  • Hertel [A measurement device positioned against both lateral orbital rims to measure the anterioposterior distance to the corneal apexes.]
  • Naugle [A measurement device positioned against the superior and inferior orbital rims to measure both the anterioposterior distance to the corneal apices and the vertial position of the globes.]
  • Luedde [A measurement device positioned against the orbital lateral rim of one orbit to measure the anterioposterior position of the globe.]
  • Mourits [A parallax-free exophthalmometry device, positioned similarly to the Hertel exophthalmometer.]
  • Computer Tomography [An imaging-based method to measure Globe position.]
