Non-penetrating glaucoma filtration surgery
Wishart PKCME Journal Ophthalmology 2001; 5: 3-7
Non-penetrating glaucoma filtration surgery, which includes deep sclerectomy and viscocanalostomy, describes an operation by which the intraocular pressure (IOP) of a glaucomatous eye is lowered by the creation of a thinned, permeable trabecular membrane at the limbus across which aqueous can leave the eye. Avoiding ocular penetration reduces the early complications of trabeculectomy which occur as a result of unrestricted bulk outflow of aqueous, shallow and flat anterior chambers, choroidal detachment, and hypotony. Lack of penetration is also associated with a reduced healing response and thus less postoperative iritis and conjunctival scarring than occurs with trabeculectomy. Prospective, medium term studies have demonstrated the safety and efficacy of non-penetrating glaucoma filtration surgery confirming good IOP control, lack of hypotony, reduced complications from thinned or cystic blebs, and a reduced rate of cataract formation.
