Filter by:A pterygium is a fibrovascular growth originating from the conjunctiva that grows onto the surface of the cornea. Frequently, these pterygia will recur even after surgical resection. Bevacizumab is an inhibitor of angiogenesis, which is needed for recurrent growth. The use of bevacizumab is poorly understood in inhibiting pterygium growth. The objective of this study is to compare the effects of wound healing and recurrence rates in postoperative bevacizumab versus pterygium excision alone.
The aim of this study was to investigate the efficacy and safety of subconjunctival bevacizumab application as an adjuvant therapy for primary pterygium.
To compare the outcomes of limbal conjunctival autograft (LCAG) versus amniotic membrane graft (AMG) when combined with intraoperative 0.02% mitomycin C (MMC) after pterygium removal in patients with recurrent pterygium.
The purpose of this study is to determine whether bevacizumab eye drop is effective in the treatment of recurrent pterygium.
Hypothesis: Subconjunctival bevacizumab injection may potentially suppress neovascularization in pterygium, preventing or retarding the progression of recurrence.
The main problem of ocular surface reconstruction is the lack of viable conjunctival tissue. The use of a biocompatible latex biomembrane in ocular surface healing, like post pterygium surgery, could be an alternative therapeutic resource to this process.
The use of Fibrin glue to place conjunctival graft will be as effective as suturing the graft, but will require much less operative time and will be better tolerated by the patients.
This study will evaluate the efficacy and safety of the use of bevacizumab (Avastin) as an adjunctive medication during pterygium surgery in preventing pterygium recurrence. A pterygium is a white fleshy growth on the surface of the eye, which can be removed surgically. However, after surgical removal, pterygia can recur. One way of minimizing recurrence is by applying a medication called mitomycin C to the surface of the eye during pterygium surgery. However, mitomycin is associated with certain side effects, such as thinning of the eye wall and poor wound healing. Bevacizumab has a different mechanism of action and there is some evidence that it may be useful in preventing pterygium recurrence. In this study, the safety and efficacy of adjunctive intraoperative use of bevacizumab and mitomycin C for preventing pterygium recurrence will be directly compared.
This study will evaluate the safety and efficacy of Cyclosporine Ophthalmic Emulsion 0.05% (RESTASIS®) in patients with primary pterygium (abnormal growth on surface of eye).
To compare the efficacy of rotational narrow strip conjunctival graft to full conjunctival graft in primary pterygium excision. Risk analysis of factors that may affects the recurrence rate.
