PURPOSE: To investigate the efficacy of umbilical cord serum eyedrops for the treatment of severe @entity936 . METHODS: Fifty-five eyes of 31 @entity1 with severe @entity936 were treated with umbilical cord serum eyedrops. Symptom scoring, tear film break-up time (BUT), Schirmer test, corneal sensitivity test, and corneal @entity941 staining were performed before and 1 and 2 months after treatment, and conjunctival impression cytology was performed before and 2 months after treatment. The concentrations of @entity4179 ( @entity4179 ), @entity904 , and transforming growth factor-beta (TGF-beta) in umbilical cord serum and normal peripheral blood serum were measured. RESULTS: Two months after treatment, significant improvement was observed in symptom score (from 3.07 +/- 0.54 to 0.96 +/- 0. 58), BUT (from 3.96 +/- 1.56 to 5.45 +/- 2.54 seconds), and keratoepitheliopathy score (from 4.87 +/- 3.22 to 1.71 +/- 1.84) (P < 0.01). There was no statistically significant change in Schirmer and corneal sensitivity tests. In impression cytology, the grade of @entity1544 (from 2.35 +/- 0.72 to 1.44 +/- 0.69) and goblet cell density (from 80.91 +/- 31.53 to 154.68 +/- 43.06 cell/mm) improved significantly (P < 0.01). The mean concentrations of @entity4179 , TGF-beta, and @entity904 were 0.48 +/- 0.09, 57.14 +/- 18.98, and 230.85 +/- 13.39 ng/mL in umbilical cord serum and 0.14 +/- 0.03, 31.30 +/- 12.86, and 372.34 +/- 22.32 ng/mL in peripheral blood serum, respectively. CONCLUSION: Umbilical cord serum contains essential tear components, and umbilical cord serum eyedrops are effective and safe for the treatment of severe @entity936 .
