Synthetic teaching case
Case 3: SRAX-driven defer
Synthetic case in which signed I-S establishes ERSS inferior steepening while confirmed SRAX >20° independently creates a PS3 High factor.
Not real patient dataThis worked example was created to teach the current CER-AI v2.0 rules. It is not a clinical decision.
Source inputs
| Field | Value |
|---|---|
| Procedure | LASIK |
| Age / thinnest | 28 years / 530 µm |
| Signed I-S | +1.20 D |
| Measured SRAX | 25°; surgeon confirms >20° |
| Final BAD-D / NICE | 1.20 / 5 |
Pathway evaluation
| System | Calculation / finding | Result |
|---|---|---|
| ERSS | Signed I-S +1.20 D establishes inferior steepening = 3 | CAUTION |
| BAD-D | Normal | PASS |
| NICE | 5 | CAUTION |
| PS3 | SRAX High factor | STOP-DEFER |
| Tissue safety | No independent stop in this example | PASS |
Final CER-AI result
STOP-DEFER
Report summary
The report preserves the ERSS and NICE cautions and the exact PS3 High finding. PS3's procedure disposition becomes a stop driver, and STOP-DEFER overrides all reassuring or caution results.
Learning points
- Signed I-S from >+1.00 D to <+1.40 D is classified as inferior steepening in ERSS.
- Exactly 20.0° is negative; >20° is positive only under the signed-I-S and confirmation policy.
- A confirmed stop remains visible even when other pathways pass.
