Patients were followed-up weekly until epithelization was complete.The collected data included the grade of corneal lesion(Grade I: epithelial defect +superficial vascularization,Grade II: epithelial defect +stromal edema, Grade III:corneal ulcer +stromal melting), the size of epithelial defect(pretreatment, 7th, 14 thand 21stdays of treatment),and follow-up time was evaluated retrospectively.RESULTS:The mean size of epithelial defect on two perpendicular axes was 5.2×4.6-mm2(range: 2.5-8 mm×2.2-9 mm2). Mean duration of treatment was 8.3 ±5wk.CBS therapy was effective in 12 eyes(75%) and ineffective in 4 eyes(25%). The epithelial defects in 4ineffective eyes were healed with amniotic membrane transplantation and tarsorrhaphy. The rate of complete healing was 12.5% by 7d, 25% by 14 d, and 75% by 21 d.The healing time was prolonged in Grade III eyes in comparison to eyes in Grade I or Grade II.CONCLUSION:The results of the current study indicated the safety effectiveness of CBS drops in the management of PED. The grade of disease seems have a role on the healing time.展开更多
