Ophthalmology Product Deployment and Upgrade

Data Characteristics for This Category

Ophthalmology product and reagent data sources include drug inserts, medical device registration certificates, clinical trial reports, academic papers, and product technical manuals. These documents are typically in PDF, DOCX, or HTML format. Data updates are irregular due to new drug approvals, device iterations, clinical guideline revisions, or adverse event report updates, usually in batches quarterly or annually. Document structures, such as inserts and registration certificates, have fixed sections like [Indications], [Dosage and Administration], [Contraindications], and [Adverse Reactions]. Fields and units involve drug dosages (e.g., mg, ml), device dimensions (e.g., mm, µm), visual acuity metrics (e.g., LogMAR, Snellen fractions), and various optical parameters.

Constraints on Deployment and Upgrade from These Characteristics

Ophthalmology data characteristics impose specific constraints on FastGPT deployment and upgrade. Large volumes of PDF and DOCX documents, especially clinical trial reports with complex tables and charts, require the knowledge base's document parsing capabilities to support multiple file types and effectively extract key information. Irregular data updates mean the knowledge base needs to support incremental update mechanisms to avoid full rebuilds with each update. Due to the specialized nature of ophthalmology, knowledge base recall and semantic understanding need high precision, especially when processing specific disease names, drug mechanisms of action, and professional terminology. Numerical data fields like LogMAR values or IOP (intraocular pressure) must retain their numerical properties during vectorization and retrieval to ensure accurate question-answering results. Therefore, deployment requires adjusting document parsing, vectorization, and retrieval configurations for these data characteristics, and ensuring compatibility during upgrades.

Configuration Settings

Configuration Item	Suggested Value	Rationale for This Value
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Ophthalmology product inserts and clinical reports are often large files; this value ensures large files upload without issues.
`maxContext`	`3000 tokens`	Complex ophthalmological pathology descriptions and treatment plans require a longer context window for understanding.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Parsing PDFs with numerous charts and complex tables can take a long time.
`Chunk size`	`800-1200 characters`	Ensures each knowledge chunk contains sufficient information while avoiding excessive length that could lead to redundancy or comprehension difficulties.
`Recall count`	`Top 5`	Improves retrieval accuracy, reduces interference from irrelevant information, and focuses on core ophthalmology knowledge points.
`Similarity threshold`	`0.75`	Ophthalmology terms and concepts require high similarity; this threshold helps filter out low-relevance results.

Three Common Mistakes

After local deployment, workflow node code execution shows "no execution result." This is usually due to an incorrect PYTHON_PATH configuration or missing necessary Python dependency libraries, preventing the function from executing.
After Docker deployment, database and service passwords cannot be changed. This occurs because environment variables are not configured correctly or relevant configuration files are not mapped in docker-compose.yml, causing changes to be ineffective.
After proxying a URL with Nginx, the original knowledge base download link still points to the original address. This happens when proxy_pass in the Nginx configuration does not correctly handle Location header rewriting or does not override the download link's domain.

How to Verify Correct Configuration

Upload an ophthalmology clinical trial report PDF with complex tables and multiple pages. Check if it parses completely and generates retrievable knowledge chunks.
Ask questions about product inserts for specific ophthalmological diseases (e.g., glaucoma, cataracts). Verify if the question-answering results accurately cite the original knowledge base text and if the cited original links are accessible.
Call the knowledge base via API to simulate batch data updates. Verify if newly added or modified data can be retrieved by the model within a short period.
