Optometry image laterality and exam linkage data for AI
An optometry exam can contain measurements and images from both eyes.
NAICS 621320 · Offices of Optometrists
An optometry exam can contain measurements and images from both eyes. The National Eye Institute describes a dilated eye exam and the checks that may form part of it. A practice can create an original test for laterality and source matching using diagrams that contain no identifiable eye images. National Eye Institute eye exam overview
Draw two abstract target images and add mock right and left labels, capture times and an exam identifier. Assign one file an inconsistent header. Ask which image matches the stated eye and encounter, and require escalation when image and record disagree. Score linkage rather than clinical interpretation.
Use your own drawings and fabricated records. Exclude retinal scans, prescriptions, face images, device exports and patient measurements. Ask an optometrist to review the scoring key.
Describe a synthetic exam linkage sample
Original Fiund exercise
A file header and the diagram's laterality label must agree
Two original abstract target drawings stand in for exam images. They contain no eye photograph, prescription, device export or actual measurement.
| Record | Source | What it records |
|---|---|---|
| OE1 | Mock exam register | Exam E1 expects right-side target R1 and left-side target L1, captured day 2. |
| OE2 | Drawing A | Visible label RIGHT, header side RIGHT, exam E1, day 2. Exact register link R1 supplied. |
| OE3 | Drawing B | Visible label LEFT, header side RIGHT, exam E1, day 2. Filename says L1 but no reviewed correction or controlling label rule supplied. |
Question for the model
Which drawing has a consistent right-side linkage, and can B be silently assigned to an eye using its filename?
Show the reference answer and checks
OE1 and OE2 consistently match drawing A to E1's right-side R1 target. OE3 conflicts between its visible LEFT label and RIGHT header, while the filename alone supplies no authorized resolution. Flag B's exact laterality discrepancy for reviewer confirmation rather than silently changing a field or assigning it to the right or left eye. The fixture evaluates source linkage, not vision, diagnosis or clinical image content.
- Trusting a filename over conflicting image and header labels without a controlling source.
- Treating the correct exam date as sufficient when laterality disagrees.
Fields to preserve
- Exam and target reference
- Defines the expected pair.
- Visible versus header laterality
- Exposes conflicting evidence.
- Capture date and correction authority
- Supports reviewed resolution.
Test another case
Add a specialist-reviewed B correction explicitly assigning LEFT. Require the corrected field and original conflict to retain their provenance.
Use original diagrams reviewed by a qualified practitioner. Exclude retinal images, faces, prescriptions and patient measurements.
