5.3 Eye Care Evidence Document Process Flow
Evidence Documents belong to the family of Evidence Objects such as measurements,
post processing, images, presentation states, DICOM Structured Reports, etc. These
are objects 1455
generated as a result of creating eye care diagnostic information after the patient has
left the acquisition stage of the procedure.
As with other Evidence Objects, Evidence Documents are used in the process of
creating a Diagnostic Report, either by reviewing or interpreting the Evidence
Document contents, or by copying selected parts into the Report. Evidence
Documents represent the uninterrupted 1460 information that is primarily managed
and used inside an eye care department, although distribution outside the
department is not precluded.

5.4 Eye Care Evidence Documents Use Cases
This section describes the specific use cases defined for the Eye Care
Evidence Documents Profile.
5.4.1 Eye Care Evidence Documents Being Created by Acquisition
Modality
A typical use case for evidence documents include them being generated at the
Acquisition 1470 Modality. A technician performs the acquisition, and the
instrument performs implicit post-processing immediately following the acquisition.
This may be entirely automatic, or require limited user inputs. An example is
glaucoma progression analysis performed on visual field analyzers, or the RNFL
analysis performed on an OPT device. The instrument provides the evidence
document at the end of the acquisition cycle. The transaction diagram for this
use case is 1475 already in Eye Care Workflow Integration Profile. IHE Eye
Care Technical Framework, Volume.1 (EYECARE TF-1): Profiles
Note 2: The DICOM standard does not define use of a specific version of PDF when encapsulated
PDF is used. This may result in incorrect display of reports when using a different PDF version
of software from that which was used to create the files. Other issues arise when using only PDF
with pixel data as the files are large and have difficulties with display. IHE EYECARE defines
specific versions required for support see EYECARE TF-2: 4.2.
