Corneal nerve sensation and tear secretion is restored after surgical injury with 44-mer PEDF+DHA. (A) Corneal sensitivity measured by Cochet Bonnet esthesiometer for each study group up to 7 weeks post injury. Higher sensitivity measurements is shown in PEDF+DHA (n = 6 rabbits) and 44-mer PEDF+DHA (n = 9 rabbits) groups than in 34-mer PEDF+ DHA (n = 9 rabbits) and vehicle (n = 6 rabbits) groups beginning at week 5. (B) Tear secretion measured by Schirmer's test showing results from week 4 to week 7 after injury for all treatment groups and control (nonsurgical) group. Higher Schirmer's scores and normal control levels are reached by week 7 with PEDF+DHA and 44-mer PEDF+DHA. *Statistically significant difference with respect to 34-mer PEDF+DHA- and vehicle-treated groups.
