View clinical trials related to Bleb Vascularity.
Filter by:Trabeculectomy is an ocular surgery intended to reduce intra-ocular pressure the surgery creates a sub-conjunctival filtering bleb which filters aqueous humor fluid out. A rather common adverse event of the surgery is increasing vascularity of the conjunctiva overlying the bleb. This leads to adherence of the conjunctiva to the sclera and fibrosis and finally failure of the bleb (and of the surgery) this study intends to demonstrate that post operative subconjunctival bevacizumab injection will reduce incidence of bleb vascularity and ultimately, bleb failure.
The occurrence of conjunctival scarring finally leads to the obstruction of the fistula tract created by the filtering surgery. Vascular endothelial growth factor is thought to be a key role in the formation of conjunctival scar, which play a pivotal role in the wound-healing process. So it seems that the recombinant human anti-VEGF antibody could inhibit angiogenesis, and reduce the conjunctival vascular formation in the wound-healing process after glaucoma filtering surgery.
