Cross-Sectional Study for an Ocular Imaging-Based Predictive Model of Inflammatory Skin Diseases Grounded in Traditional Chinese Medicine
Source: ClinicalTrials.gov · Last updated 25 Feb 2026
Brief summary (registry, in English)
This study is a cross-sectional, observational investigation designed to develop and validate a noninvasive ocular imaging-based predictive model for major inflammatory skin diseases, including psoriasis, atopic dermatitis, and urticaria. Grounded in Traditional Chinese Medicine (TCM) ocular diagnostic theory and integrated with advanced computer vision techniques, the study aims to establish objective, quantifiable biomarkers derived from scleral and bulbar conjunctival images. Approximately 950 participants (patients with psoriasis, atopic dermatitis, urticaria, and healthy controls) will be recruited from a tertiary academic hospital. Standardized high-resolution ocular images will be collected alongside comprehensive clinical, demographic, and comorbidity data. Disease severity will be assessed using validated clinical scoring systems (e.g., PASI, EASI, UAS7, DLQI). Image analysis will combine traditional radiomics feature extraction with deep learning architectures, including a Vision State-Space (VMamba) module for global-local feature representation and a Multi-Gate Mixture-of-Experts (MMoE) framework for multi-task learning. The model is designed to simultaneously perform disease classification and predict comorbidity risks (such as metabolic syndrome, hepatic insulin resistance, and recurrence risk). Primary outcomes include characterization of ocular feature patterns associated with inflammatory skin diseases. Secondary outcomes include correlations between ocular image-derived features and clinical severity indices. Model performance will be evaluated using ROC curves, AUC, calibration analysis, and decision curve analysis. This study aims to provide an objective, digitalized, and clinically applicable ocular biomarker framework to support early diagnosis, risk stratification, and comorbidity screening in inflammatory skin diseases.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Participation in other clinical trials within the previous 3 months or concurrent participation in other interventional studies.
- Healthy control - exclusion criteria
- Exclude any subject meeting any of the following:
- Presence of other skin diseases that could affect study assessments (e.g., atopic dermatitis, urticaria, scabies).
- Refusal to undergo examinations.
- Acute/active infectious ocular disease (e.g., viral keratoconjunctivitis).
- Corneal perforation or high-risk perforation that causes severe photophobia, eye pain, inability to keep eyes open or fixate during contact procedures.
- Nystagmus or other reasons preventing fixation.
- Pupillary non-dilation (e.g., posterior synechiae) that prevents fundus imaging.
- Participation in other clinical studies within the previous 3 months or currently participating in other clinical trials.
Other illness
- For patients with inflammatory skin disease:
- Presence of acute/active infectious ocular disease (e.g., viral keratoconjunctivitis).
- Corneal perforation or high-risk perforation where contact procedures cause severe photophobia, eye pain, inability to keep eyes open or fixate.
- Nystagmus or other conditions that prevent fixation.
Other
- Exclude any subject meeting any of the following:
- Refusal to undergo examinations.
- Pupillary non-dilation (e.g., posterior synechiae) that precludes fundus imaging.
- Severe eyelid lesions (e.g., marked swelling, ectropion, entropion) that prevent globe exposure.
