简要总结
Tisseel fibrin adhesive has been used extensively in many forms of surgery. Its use in eye surgery has been relatively recent. A few studies recently showed it was effective in securing conjunctival grafts in pterygium surgery, and in securing wounds after glaucoma and squint surgery.
We sought to confirm its effectiveness in pterygium surgery, as well as prove its effectiveness in securing other material to the ocular surface such as amniotic membrane. Our hypothesis is that fibrin adhesive is effective in securing various types of material to the ocular surface for a sufficient length of time to allow adequate healing before it is absorbed and degraded.
详细描述
AIMS OF STUDY:
This project seeks to evaluate the efficacy of fibrin glue (Tisseel) as an alternative to conventional sutures in ocular surface reconstruction, including pterygium excision with conjunctival autografting and other forms of conjunctival and amniotic membrane surgery.
It aims to evaluate the safety and efficacy of fibrin glue in pterygium and other forms of ocular surface conjunctival and amniotic membrane surgery, as an alternative to conventional suturing. We will perform conjunctival autografting in 30 patients with primary or recurrent pterygium, and in addition, up to 20 patients undergoing either conjunctival or amniotic membrane ocular surface reconstruction for a variety of diverse ocular surface disorders including persistent epithelial defects, Stevens Johnson syndrome, chemical and thermal burns and other fornix shortening/symblepharon conditions. Efficacy endpoints will be the ability of fibrin glue to form stable adherence of the conjunctival/AM graft postoperatively, and in cases of pterygium, the percentage of pterygium recurrence at 6 months following surgery, and subjective indications of postoperative comfort/discomfort. Safety data will include the close monitoring of any potential side-effects including graft loss, infection, pain/discomfort, excessive ocular surface inflammation, epithelial breakdown, and any complications resulting in visual loss. Patients will not be charged for the fibrin glue.
If successful, the use of fibrin glue will be a useful adjunct in ocular surface reconstruction, reducing time of surgery and suture-related complications and discomfort. The cost-benefit ratio will need to be examined, but full-paying patients who can afford it may be offered fibrin glue in pterygium surgery as a surgical option.
