Abstract: The present invention relates to treatment of dry eye syndrome using a tanfanercept-containing ophthalmic composition. According to the present invention, as a result of clinical trial on dry eye syndrome, the tanfanercept-containing ophthalmic composition demonstrated excellent effects with regard to improvement of a central corneal staining score (CCSS) and a total corneal staining score (TCSS), which is clinically important. Further, such improvement of a central corneal staining score (CCSS) and a total corneal staining score (TCSS) was more significantly demonstrated in the patients with moderate-to-severe severity of dry eye. In addition, the patients with higher ocular discomfort score or higher eye dryness score, which are subjective symptoms, also showed greater improvement. Even though the same dose of tanfanercept was used, the tanfanercept-containing ophthalmic composition showed superior efficacy in the patient having more serious or severe baseline sign or symptom scores.
