About this study

Official title: Randomized Controlled Trial to Compare Fibrin Glue and Suture in Primary Pterygium Excision With Amniotic Membrane Transplantation

The purpose of this study is to compared between conventional pterygium excision and AMT transplantation with suture and with fibrin glue.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Amniotic membrane transplantation using fibrin glueProcedure or surgery

    Also called Quixil®, Nylon 10-0

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain and discomfort during and after surgery using visual analog scale

    Measured: during surgery and after surgery up to 30 days

Secondary outcomes (4)
  1. Surgical time

    Measured: start and to the end of surgery

  2. Healing of epithelial defect on cornea and AMT

    Measured: until 30 days

  3. Postoperative inflammation

    Measured: up to 30 days

  4. Complications e.g. Recurrent, graft loss/dehiscent, re-operation

    Measured: until last follow up

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Amniotic membrane transplantation using fibrin glue in people with Pterygium, run by Chulalongkorn University at 1 site in Thailand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Feb 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain and discomfort during and after surgery using visual analog scale (time frame: during surgery and after surgery up to 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2008.
