Further study details as provided by Chulalongkorn University:

Primary Outcome Measures:
  • Pain and discomfort during and after surgery using visual analog scale [ Time Frame: during surgery and after surgery up to 30 days ]

Secondary Outcome Measures:
  • Surgical time [ Time Frame: start and to the end of surgery ]
  • Healing of epithelial defect on cornea and AMT [ Time Frame: until 30 days ]
  • Postoperative inflammation [ Time Frame: up to 30 days ]
  • Complications e.g. Recurrent, graft loss/dehiscent, re-operation [ Time Frame: until last follow up ]

Enrollment: 32
Study Start Date: April 2007
Study Completion Date: August 2007
Primary Completion Date: August 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1Fibrin glue
After pterygium excision, amniotic membrane was shaped and attached to bare scleral area using fibrin glue (Quixil®)
Procedure: Amniotic membrane transplantation using fibrin glue
After pterygium excision, amniotic membrane was shaped and attached to bare scleral area using fibrin glue (Quixil®) in 16 eyes of 16 patients of FG group and continuous suture with nylon 10-0 in 16 eyes of 16 patients of SU group.
Other Names:
  • Quixil®
  • Nylon 10-0
Active Comparator: 2 Suture
After pterygium excision, amniotic membrane was shaped and attached to bare scleral area using continuous suture with nylon 10-0

Detailed Description:

There are few studies about use of fibrin glue in pterygium surgery with conjunctival auto-graft with promising outcome. Less recurrent rate, less discomfort and halve surgical time were reported.

Up to our knowledge,there is no report of fibrin glue in pterygium excision with amniotic membrane transplantation(AMT). There is conventional technique to use AMT in King Chulalongkorn Memorial Hospital because some benefits over conjunctival auto-graft e.g.

  • Preserve healthy superior conjunctiva for future glaucoma filtering surgery
  • Can use in big or 2-headed pterygium
  • Not contract as conjunctival graft esp. in case of fibrin glue
  • Potential easier to use with fibrin glue
  • Available from Thai Red Cross Eye Bank Comparison(s): amniotic membrane transplantation using fibrin glue compare to suture after pterygium excision.
