Eye Care DomainEye Care Domain

Ophthalmology, Optometry

Market dominated by small clinics, group practices, and solo providers Lack IT infrastructure of hospital environment

Broad spectrum of modalities Digital fundus cameras, digital slit-lamp cameras Visual field analyzers OCT scanners, Scheimpflug cameras Ophthalmic ultrasound Corneal topographers Lensometers, auto-refractors, keratometers, other refractive devices Etc.

Rapid adoption of large-data-volume imaging modalities Spectral domain OCT: 3-D, 4-D imaging of retinal structures

Early adoption phase of PACS, DICOM, IHE Analogous to radiology in the 1990’s

IHE Eye CareIHE Eye Care

Roots in DICOM Working Group 9 (Ophthalmology)

AAO sponsorship; recent ASCRS support

Leadership by clinical committee members

Increasing vendor support (Modality, EMR, Image Management, Practice Management)

Initiative started in 2005; currently in 3rd year

Separate October Connectathons (at RSNA headquarters)

IHE Showcases at AAO meetings (typically in November)

Planning IHE Showcases also at ASCRS meetings (typically April)

Technical FrameworkTechnical Framework

4 Integration Profiles:

EYE CARE Workflow (EYECARE )

establishes the continuity and integrity of basic patient and procedure data in the context of an eye care clinic and/or an integrated hospital workflow scenario; derived from radiology scheduled workflow

Charge Posting (CHG)

specifies the exchange of information from department ordering systems to billing systems regarding charges associated with particular procedures

Eye Care Evidence Documents (ECED)

defines ways for evidence documents such as procedure observations and image measurements to be stored and displayed

Eye Care Displayable Reports (ECDR)

defines ways for display-ready eye care reports such as interpretation reports to be stored and displayed

Future PlansFuture Plans

2008 is catch-up year – little new Technical Framework development Constrain DICOM Enc PDF to PDF/A-1a

Current Mission: Significantly increase professional community awareness of

and participation in IHE Eye Care Develop a significantly more effective IHE Eye Care

showcase Broaden vendor participation in IHE Eye Care Foster real life IHE Eye Care implementations to meet

clinical needs Broaden participation of eye care organizations in the US

and internationally
