Artifacts Summary

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

Structures: Resource Profiles

These define constraints on FHIR resources for systems conforming to this implementation guide

OCT macula Diagnostic Report

The DiagnosticReport profile for an OCT macula

OCT RNFL Diagnostic Report

The DiagnosticReport profile for an OCT RNFL

OCT RFNL Observations

The Observations associated with the OCT RNFL DiagnosticReport (note: this valueset can also be used independently to describe specific findings/Observations captured by a OCT test, which may not necessarily be referenced by the DiagnosticReport.)

Intraocular Pressure (IOP)

A measurement of a patient’s intraocular (within the eyeball) pressure (in mmHg).

OCT macula Observations

The Observations associated with the OCT macula DiagnosticReport (note: this valueset can also be used independently to describe specific findings/Observations captured by a OCT test, which may not necessarily be referenced by the DiagnosticReport.)

Opththalmic Procedure

A profile indicating that an active ophthlmic intervention is or was performed on or for a patient. The ‘Ocular anatomical location’ profile should be used together with this profile.

Ocular anatomical location

The description of an ophthalmic anatomical site that is located within the following structures: the eyeball or the periocular or orbital regions (as opposed to non-ocular anatomical locations). This profile is used by combining the unique valueset (hyperlink) for relevant ophthalmic specific BodyStructure.locationQualifier (Body Site modifier) in combination with the base Observation BodyStructure.location (Body Site; descendants from SNOMED 371398005 (Eye Region Structure), each with a preferred binding in order to refine the accuracy of the location decription of occular structures. This unique qualifying element is important because these locations are routinely described either diffently and/or more granularly than other body parts. Of note - non occular (or surrounding) anatomical location references of Observations (eg - arm) do not need to use this modified specialty profile.

Visual Acuity (VA)

An assessment of a patients ability to see.

Ophthalmic diagnostic test report

Base profile specifically constrained for describing ophthalmic reports

Base ophthalmic Observation profile

Base profile specifically constrained for describing ophthalmic Observations

VF Diagnostic Report

The DiagnosticReport profile for a visual field DT

Ophthalmic Diagnoses

A profile to describe the formal past/present clinical diagnosis of a specific non-ophthalmic pathological Condition. As noted above, although the Condition Resource is also referenced in the non-ophthalmic findings profile, this profile is a modification of the base Condition Resource (as opposed to a base Obervation Resource modification, referencing Condition).

VF Observations

The Observations associated with the VF DiagnosticReport (note: this valueset can also be used independently to describe specific findings/Observations captured by a VF test, which may not necessarily be referenced by the DiagnosticReport.)

Other ophthalmic clinical Observation

Observations made during an ophthalmic clinical examination that relate to ocular structures (and hence should use the ““ocular anatomic location”” profile). Although the Condition resource is used in this profile (with the preferred binding of a specific ophthalmic valueset), this does not intend to indicate that a definitive clinical diagnosis has been made. Rather, that a certain finding has been observed. Observations made during a clinical examination which may or may not be related to the routine ophthalmic examination, but describes findings that are not necessarily related to the ocular, periocular or orbital anatomical location or pathology (and hence is unlikely to requre the use of the “ocular anatomic profile”).

Terminology: Value Sets

These define sets of codes used by systems conforming to this implementation guide

Ophthalmic anatomical location qualifiers

Describes whether a recorded observation is either final or amended

Ophthalmology Condition ICD10 and SNOMED codes ValueSet

Clinical findings for the eye region.

Observation Status

Describes whether a recorded observation is either final or amended

Intraocular pressure (IOP) method valueset

Describes the various methods of capturing IOP that relate to the IOP Observation profile

This ValueSet represents procedure codes for clinical and billing purposes.

Visual acuity chart valueset (SNOMED)

Describes the various charts that can be used to assess visual acuity where concept descends from 400912000 (Visual acuity test equipment (physical object))

Visual Field Observable Entities ValueSet

Visual field observation coding

Ophthalmology observations (SNOMED)

Concept descends from 363926002 - Eye/vision observable (observable entity)
