Device Story
Desktop retinal imaging device combining ultra-widefield scanning laser ophthalmoscopy (SLO) and spectral domain optical coherence tomography (OCT). SLO uses red/green lasers for reflectance and autofluorescence imaging; OCT uses near-infrared super-luminescent diode (SLD) for axial cross-sectional/3D imaging. Device uses ellipsoidal mirrors and galvanometric scanners to capture retinal data. Operated by ophthalmic/optometry professionals in clinical settings. System includes scan head, touchscreen, hand controller, and image server for storage/EMR integration. Software automatically segments retinal layers and compares metrics (Full Retinal Thickness, GCC, RNFL, ONH) against a built-in reference database of 860 healthy subjects. Clinicians review images/annotations on connected PCs to assess retinal health, monitor disease progression, and document findings. Benefits include high-resolution, wide-field visualization and quantitative comparison to normative data to aid clinical decision-making.

## 4. Device Description
The P200TE is a desktop retinal imaging device that can perform ultra-widefield scanning laser ophthalmoscopy and optical coherence tomography. Ultra-widefield images can be captured in less than half a second. The device is intended to be used by ophthalmic and optometry health care professionals.
The P200TE delivers images in the following image modes:
- . Scanning Laser Ophthalmoscopy
- . Reflectance imaging
- . Autofluorescence imaging
- . Optical Coherence Tomography
The P200TE instrument uses red and green laser illumination for reflectance imaging, enabling it to image pathology throughout the layers of the retina, from the sensory retina and nerve fiber layer, through the retinal pigment epithelium (RPE) and down to the choroid. The image can be separated to present the distinct retinal sub-structures associated with the individual imaging wavelengths.
The P200TE instrument uses green laser illumination to excite autofluorescence (AF) emission from the naturally occurring lipofuscin in the fundus.
The P200TE instrument uses a broadband near-infrared (N-IR) super-luminescent diode (SLD) light source for optical coherence tomography allowing a depth profile of the reflectance of the fundus to be recorded. The P200TE instrument uses N-IR laser illumination for reflectance imaging simultaneously with OCT imaging. Reflectance images are used to track eye position during OCT imaging and are not available to the user.
The P200TE images the eye via two ellipsoidal mirrors arranged so that a focal point of one of the mirrors coincides with a focal point of the other mirror; a mirrored scanner is also located at this common focal point. The pupil of the subject's eye is placed at one of the other focal points. A second mirrored scanner is located at the remaining focal point; a laser or SLD reflected off this scanner is relayed onto the second scanner by the first ellipsoidal mirror and from there is reflected through the pupil and into the eve by the second ellipsoidal mirror. The second scanning element is different for OCT and SLO imaging. The energy reflected back from the retina, or emitted by fluorophores, returns through the same path to the detectors; the images are generated from the captured detector data.
P200TE OCT images are automatically segmented to identify and annotate retinal layers and structures, enabling practitioners to efficiently assess retinal structures in support of detecting, monitoring and documentation. A Reference Database enables the automatic annotation of OCT segmentation results to provide comparison to a known healthy population. Segmentation outcomes are recorded as annotations and support adjustment as deemed necessary by the clinician.
{6}------------------------------------------------
Image /page/6/Picture/1 description: The image shows the Optos logo. The logo consists of a stylized eye symbol on the left and the word "optos" in blue, sans-serif font on the right. The eye symbol is a combination of light and dark blue shades, creating a sense of depth. The word "optos" is in a bold font, and there is a registered trademark symbol next to the "s".
P200TE automatic seqmentation provides comprehensive retinal and optic nerve head information, including:
- . Full Retinal Thickness (FRT)
- . Ganglion Cell Complex Thickness (GCC)
- ONH Analysis
- ONH Nerve Fiber Layer Thickness
The P200TE refers to the scan head component of the system. together with touchscreen and hand controller. The device is supported by an image server which delivers patient management and image storage, as well as interfacing with the business systems and Electronic Medical Record systems.
The images are captured by the scan head under operator control and then automatically saved to the image server that uses a database structure to hold the images and patient information. For subsequent image review, a number of viewing PCs are connected remotely or via a local area network to the image server. The patient records and images are then accessible in a distributed format suited to the physical layout of the eye-care practice.
Images can be reviewed through OptosAdvance review software (K162039) either on the image server, or on individual review stations, or other compatible PACS viewers.
### 5. Indications for Use

## 6. Substantial Equivalence to Predicate
Both P200TE and iVue are Spectral Domain optical coherence tomographers intended for in-vivo digital imaging of posterior ocular structures, with retinal laver boundary analysis, optic nerve head analysis and thickness maps. Both devices provide a reference database to allow comparison of measurements against a database of known subjects.
The updated P200TE has all the same indications for use as P200TE and alongside this introduces the opportunity for comparison to a reference database, present in the primary predicate device, iVue. In other words, the P200TE has the same intended use as its predicate devices, and thus satisfies the first criterion for a finding of substantial equivalence.
The Optos Reference Database (RDB) enables the automatic annotation of OCT segmentation results to provide comparison to a known healthy population cohort of 860 subjects across an age range 22-84 years, with an average age of 51. This is shown in terms of percentiles. Cut-off values of 1%, 5%, 95%, and 99% (determined with a nonparametric method) are used to color-code results to indicate where they fall in relation to database distribution. This is similar to iVue, which uses color-coded percentile categories to denote 'within normal', 'borderline', or 'outside normal' based on cut-off levels of 5% for 'borderline' and 1% for 'outside normal'.
The Optos RDB is partitioned into three strata, based on optic disc size as the prioritized covariate for RNFL and ONH RDB comparisons. It is non-parametric, with an age profile intended to mirror disease prevalence. These covariates are selected in line with the parameters used in the predicate iVue database.
Technological implementation of SLO and OCT imaging is identical between the cleared P200TE and this submission of the P200TE with RDB. No technological updates are included in this submission.
P200TE with segmentation and RDB is substantially equivalent to the previously cleared P200TE (K231673), and RDB functionality is also substantially equivalent to the Optovue iVue (K121739). Minor differences in RDB implementation do not present different questions of safety or effectiveness than the predicate device because there are no novel technological principles or applications introduced.

Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
