Comparative Study between Stab Incision Glaucoma Surgery and Subscleral Trabeculectomy in Management of Primary Open Angle Glaucoma

Abstract
laucoma is a leading cause of permanent blindness worldwide, affecting about 2-3% of people above the age of 40, yet around half of them remain undetected.
Open angle glaucoma comprises a multifactorial disease characterized by loss of retinal ganglion cells that leads to a distinctive optic neuropathy and associated visual field loss. Elevated intraocular pressure (IOP) is considered the principal risk factor for the development and progression of glaucomatous neuropathy.
Reduction in intraocular pressure is the only treatable risk factor for glaucoma and may be achieved by either medical, laser or surgical intervention.
SST is the gold standard surgery for reducing IOP in patients with glaucoma, where after raising a conjunctival flap, a fistula is made between the anterior chamber and the subconjunctival space under a scleral flap leading to aqueous humor drainage and subsequent bleb formation
The rates of success and specific complications with trabeculectomy are widely known. A big disadvantage of trabeculectomy is the need for a conjunctival peritomy and subconjunctival dissection. Creation of either a limbal- or fornix-based conjunctival flap for any kind of procedure invariably induces sub-conjunctival fibrosis which can lead on to filtration failure secondary to scarring.
SIGS was developed by Dr. Soosan Jacob in 2014 in an effort to avoid many of the trabeculectomy disadvantages while simultaneously making filtration surgery easier, faster, less traumatic, & more likely to succeed. A 2.8-mm bevel-up keratome is used to fashion a sclero-corneal tunnel in a single step & then intentionally compromise the tunnel by punching the posterior corneal lip.
A major advantage of SIGS is complete elimination of subconjunctival dissection, thereby decreasing the risk of a failed filter from scarring.
The aim of this study was to compare between SIGS and SST in management of primary open angle glaucoma over a short term follow up period as regards IOP control, bleb morphology and occurrence of postoperative complications.
The present study was a single blinded prospective randomized clinical trial. It was conducted at the Ophthalmology department, Ain shams university hospitals, from May 2016 to June 2017. It included 20 eyes of patients who underwent glaucoma surgery for 1ry open angle glaucoma, with informed consent obtained from every patient.
Patients who met the inclusion criteria were subjected to history taking including ocular trauma, medications or surgeries, ophthalmological examination including visual
