Novel thermal imaging analysis technique for detecting inflammation in thyroid eye disease

Area of Science:

• Ophthalmology
• Medical Imaging
• Therapeutics

Background:

• Thyroid eye disease (TED) phase assessment relies on clinical evaluation and the clinical activity score (CAS), the current standard.
• An objective tool would enhance the accuracy of disease phase determination in TED.

Purpose of the Study:

• To evaluate the clinical utility of a new thermal imaging analysis technique for objectively quantifying eye and peri-orbital thermal characteristics.
• To determine the disease phase in TED using thermal imaging parameters.

Main Methods:

• A cross-sectional study involving 30 TED patients (17 active, 13 inactive) was conducted.
• Standard ophthalmological assessments and thermal imaging were performed.
• Five novel thermal eye parameters (TEP) were developed to quantify inflammation and temperature variability.

Main Results:

• All five thermal eye parameters (TEP) were elevated in active TED compared to inactive TED.
• TEP1 achieved 77% accuracy in differentiating active from inactive TED.
• A statistical model combining all five TEPs improved diagnostic accuracy to 93%.

Conclusions:

• The novel thermal imaging analysis technique demonstrates potential for objectively assessing TED disease phase.
• Further research with larger patient cohorts is needed to validate these findings.
