title: Autologous fibrin membrane combined with solid platelet-rich plasma in the management of perforated corneal ulcers: a pilot study.
abstract: OBJECTIVE
  The combined use of autologous fibrin membrane and the eye platelet-rich plasma (E-PRP) clot could be considered as a new surgical alternative for the closure of corneal perforations.
  
  
  OBJECTIVE
  To evaluate the use of autologous solid platelet-rich plasma in combination with an autologous fibrin membrane as a surgical alternative for wound closure in perforated corneal ulcers.
  
  
  METHODS
  Both the fibrin membrane and the E-PRP clot were prepared with the patient's own blood just before the operation. Nylon stitches were used to fixate the fibrin membrane to the conjunctiva and then the E-PRP clot was placed over the corneal perforation, underneath the fibrin membrane. A temporal partial tarsorrhaphy was performed at the end of the procedure. We conducted postoperative monitoring for 3 months. SETTING Vissum Corporacion Oftalmologica, Alicante, Spain.
  
  
  METHODS
  Eleven patients with perforated corneal ulcers.
  
  
  METHODS
  Surgical alternative for the closure of corneal perforation.
  
  
  METHODS
  Corneal biomicroscopy, fluorescein test, digital tonometry.
  
  
  RESULTS
  In all cases the corneal perforation was sealed. The fibrin membrane was present over the corneal surface for the first 3 to 5 days and then gradually disappeared. No evidence of infection or inflammation was detected. Digital tonometry confirmed acceptable levels of ocular tonus in all cases from day 2 after the operation. No patients reported pain, discomfort, or other symptoms, and no complications were observed. After 3 months' follow-up, there was no evidence of relapses or perforations. Corneal grafting was eventually performed in 7 of the 11 cases.
  
  
  CONCLUSIONS
  The combined use of autologous fibrin membrane and E-PRP clot is a safe and effective surgical alternative for the closure of corneal perforations. This technique can be considered as a temporary measure until the condition of the cornea permits definite intervention.
