New glaucoma surgeries in and around Schlemm's canal / 眼科

ABSTRACT

Filtration surgeries,especially trabeculectomy,are the most common surgeries for glaucoma.Although trabeculectomy has excellent efficacy for reducing intraocular pressure(IOP),glaucoma filtering blebs have been frequently associated with various postoperative complications including filtering bleb failure and ocular surface dysfunctions.Surgical treatments of the natural aqueous outflow system,in and around Schlemm's canal,to restore normal function without penetration of the intraocular space has been considerable interest in recent years as glaucoma surgeons continue their quest for a procedure that reduces IOP without the risk related with filtering bleb.As a result,more blebless glaucoma surgeries have developed gradually in the past years.
