Indications for Use
The Retina Workplace is a FORUM® application intended for processing and displaying image and optical coherence tomography data. It is also intended for generating reports that contain results from optical coherence tomography and fundus photography. The Retina Workplace uses CIRRUS™ algorithms and normative databases as quantitative tool for the comparison of macular thickness data to a database of normal subjects. The Retina Workplace is intended to aid trained healthcare professionals in the detection, monitoring and management of ocular diseases including, but not limited to, macular holes, cystoid macular edema, diabetic retinopathy and age-related macular degeneration.
Device Story
Retina Workplace is a software application client for the FORUM PACS server; processes/displays OCT data and fundus images. Inputs: OCT exam data and fundus images from CIRRUS HD-OCT/Photo systems. Processing: utilizes previously cleared CIRRUS algorithms/normative databases for macular thickness analysis (MTA), macular change analysis (MCA), and 5-line raster analysis; performs automatic/manual image registration (Fovea Finder/AutoCenter). Outputs: processed images, quantitative analysis results, and clinical reports. Used in clinical settings by ophthalmologists/optometrists to review patient records. Output aids clinicians in detecting/monitoring ocular diseases by comparing patient data against age-matched normative populations. Benefits: facilitates efficient clinical workflow, standardized reporting, and longitudinal monitoring of retinal conditions.
Clinical Evidence
Bench testing only. Verification included unit, system integration, and system testing against product requirements. Direct comparison testing confirmed that reports generated by Retina Workplace were equivalent to those from CIRRUS HD-OCT and CIRRUS Photo using identical test data. Non-clinical validation involved ophthalmologists using production-equivalent systems with representative clinical data to confirm workflow functionality.

# INDICATIONS FOR USE (21 CFR §807.92(a)(5))
The Retina Workplace is a FORUM® application intended for processing and displaying image and optical coherence tomography data. It is also intended for generating reports that contain results from optical coherence tomography and fundus photography.
The Retina Workplace uses CIRRUS™ algorithms and normative databases as quantitative tool for the comparison of macular thickness data to a database of normal subjects.
The Retina Workplace is intended to aid trained healthcare professionals in the detection, monitoring and management of ocular diseases including, but not limited to, macular holes, cystoid macular edema, diabetic retinopathy and age-related macular degeneration.
# DEVICE DESCRIPTION(21 CFR §807.92(a)(4))
The Retina Workplace is a software application to a Class II medical device regulated under 21 CFR §892.2050 and therefore is a Class II medical device. As a software application of the FORUM PACs system (server), the Retina Workplace client is designed to process and display CIRRUSTM HD optical coherence tomography (OCT) data and images provided by Fundus photography.
More specifically, the Retina Workplace processes the retrieved OCT exam data from CIRRUS HD-OCT and CIRRUS Photo images from the FORUM server to display the results of macular thickness analysis (MTA), macular change analysis (MCA), and 5 line raster analysis. The results may be compared against an age-matched population of normal subjects. Analysis and databases comparison is performed by using algorithms and normative databases previously cleared in CIRRUS HD-OCT (K111157) and CIRRUS Photo (K112184) predicate devices. The reports generated by the Retina
{6}------------------------------------------------
# 510(K) SUMMARY
Workplace can be displayed, printed, and the patient record can be stored back on the FORUM server database.
In addition, Retina Workplace can automatically register images generated by Fundus photography with the OCT cube image when provided in a valid DICOM format, including the necessary pixel spacing. Additionally, the user has the option to register the fundus / OCT images manually. The automatic/manual image registration features (Fovea Finder™ and AutoCenter™) are currently cleared on the CIRRUS™ HD-OCT system (K111157) and CIRRUSTM Photo (K112184) devices.
The Retina Workplace provides the same overlays as included in the currently cleared CIRRUS HD-OCT system such as:
- Fundus image overlay with another fundus image. (Fundus to Fundus registration)
- ILM-RPE overlay on the fundus image. (Inner limiting membrane / retinal ● pigment epithelium)
- ETDRS overlay on the fundus image. (Early Treatment of Diabetic Retinopathy ● Study)
# RISK MANAGEMENT AND GENERAL SAFETY AND EFFECTIVENESS
The device labeling contains instructions for use and any necessary cautions and warnings, to provide for safe and effective use of the device.
Risk management is ensured via a risk analysis, which is used to identify potential hazards and mitigations. These potential hazards are controlled by software means, user instructions, verification of requirements, and validation of the clinical workflow to ensure that the product meets its intended uses. ZEISS adheres to recognized and established industry practice and relevant international standards where indicated.
Refer to Sections 16 and 21 for the Risk Management documentation.
# TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE (21 CFR §807.92(a) (6)):
The Substantial Equivalence comparison chart (Section 12) demonstrates the comparison of the technological characteristics of the Retina Workplace to the currently cleared predicate devices. The reference predicate, FORUM Glaucoma Workplace is the first clinically focused client accessory to the FORUM PACS server. The design of the FORUM PACS server is to support clinically focused client workplaces to aid the optometric and ophthalmology clinicians with the processing, display, review, management, and storage of digital data contained in patient records.
The Retina Workplace is substantially equivalent to the predicate devices with regard to the indications for use statement and is functionally equivalent to the predicate devices as follows:
Carl Zeiss Meditec AG
{7}------------------------------------------------
- . The Retina Workplace and the predicate device. FORUM (K122938), supports the generation of reports which contain the results from optical coherence tomography data and Fundus photography and a variety of overlays.
- . The Retina Workplace and the predicate device FORUM (K122938) are software devices, whereas the predicate devices, CIRRUS HD-OCT (K111157) and CIRRUS Photo (K112184) are ophthalmic devices which have both software and hardware functionalities. The primary software functionalities to support clinically focused analysis of the retina in the predicate devices are implemented in the Retina Workplace.
- . The Retina Workplace and the predicate devices, CIRRUS HD-OCT [with Retinal Nerve Fiber Layer (RNFL), Macular, Optic Nerve Head and Ganglion Cell Normative Databases (K111157)] and CIRRUS photo (K112184), process OCT exam results and display these results in relation to a normative database.
Note: The Retina Workplace, Release 1, supports the currently cleared macular thickness analysis (MTA), macular change analysis (MCA), and 5 line raster analysis only. The results may be compared against an age-matched normative population database of normal subjects which has been previously cleared in the CIRRUS HD-OCT system (K111157) and the CIRRUS Photo (K112184) devices. The MTA, MCA, and 5 line raster analysis software applications and normative databases remain unchanged from the currently cleared versions in the CIRRUS HD-OCT and CIRRUS Photo products.
- The Retina Workplace and the reference FORUM Glaucoma Workplace ● (K141297) are similar workplaces in design as they are both clients of the FORUM server, each a clinically focused workplace to support the work flow of the optometric and ophthalmic clinicians and their staff.
## PERFORMANCE DATA & SUMMARY OF VERIFICATION AND VALIDATION ACTIVITY (21 CFR §807.92(B)):
## Bench Testing (21 CFR §807.92(b) (1))
Performance testing, in the form of software bench testing, was conducted on the Retina Workplace in the form of Unit. System Integration, and System testing against the documented product requirements. Verification and validation testing was performed to evaluate the performance and functionality of the software and the device has been found to perform as intended. Each function and/or feature was tested by means of an appropriate test case for the test specification. The verification testing demonstrates that the device performance complies with specifications and requirements identified for the Retina Workplace.
{8}------------------------------------------------
# 510(K) SUMMARY
The software verification activities were divided into three phases:
- Tests accompanying development (including code inspections)
- . Module and integration test phase - stabilization phase
- . System verification
As part of the verification testing, in a direct comparison test, the original OCT test reports generated on the CIRRUS HD-OCT and CIRRUS photo were compared to the reports generated by the Retina Workplace using the same test data, to verify that the results contained in both reports were equivalent.
The software verification and regression testing has been performed successfully to meet their previously determined acceptance criteria as stated in the Test Plan.
## Testing Environment:
The client and server operating systems were also evaluated during verification. The results determined that client, the Retina Workplace, is suitable for the same operating systems for which the respective server, FORUM, is released and that it is suitable under the following operating systems:

Part 1 — Search, results, and everyday workflows 16 min
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.
