Five oculoplastic specialists independently evaluated five STS of CAS using periocular photographs. Inter-observer agreement and concordance between photographically (P-STS) and clinically (C-STS) assessed STS, assessment consistency, were analyzed using Kappa statistics. Diagnostic accuracy of P-CAS was evaluated via receiver operating characteristic (ROC) curves with additional analysis incorporating demographic variables such as sex, age, and smoking dose.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Assessment consistency was moderately good for redness of eyelid and conjunctiva (Kappa\u2009=\u20090.418, 0.499). The diagnostic performance of P-CAS (area under the curve, AUC\u2009=\u20090.774) was lower than that of clinical CAS (C-CAS) (AUC\u2009=\u20090.818,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007), However, it significantly improved when demographic factors were added (AUC\u2009=\u20090.851).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Periocular photography provides a reproducible and clinically valuable adjunct for assessing TED activity. The redness-related items showed higher agreement than swelling-related ones, and integrating demographic variables enhances diagnostic performance. This approach may contribute to standardizing TED assessment and serve as a foundation for future automated or image-based evaluation tools.<\/jats:p>\n
