This prospective study involved 14 patients aged > 18 years with RCUs not responding to conventional treatment. All patients were treated with E-PRP drops (one drop), preservative-free artificial tears, antibiotic eye drop four times daily and systemic vitamin A once daily for one month. All patients were examined at 1, 2, 4, 6 and 8 weeks after the treatment initiation. In each visit, the following parameters were assessed: best corrected visual acuity (BCVA), anterior segment, corneal healing, condition of the conjunctiva, presence of abnormal discharge and symptoms reported.
