Visco-Circumferential-Suture-Trabeculotomy Versus Rigid Probe Viscotrabeculotomy in Primary Open Angle Glaucoma

Visco-Circumferential-Suture-Trabeculotomy versus Rigid probe Viscotrabeculotomy in Primary Open Angle Glaucoma.

Inclusion Criteria:- The diagnosis of OAG was based on the optic nerve head appearance typical to glaucoma (increased optic disc cupping, thinning of the neuro-retinal rim, focal notching, splinter haemorrhage), corresponding visual feld loss typical to glaucoma coupled with an elevated IOP above the statistical normal of 21 mmHg and a gonioscopically open angle in the absence of any known cause for glaucoma. IOP-lowering medications were initiated for all patients and only those patients in whom control of the disease failed (as evidenced by progressive optic nerve damage and/or visual feld deterioration) and the decision for surgical intervention to lower the IOP was taken were enrolled in the study. Adult patients (above 18 years of age) fulflling these criteria were enrolledExclusion Criteria:Other types of glaucomas and co-morbidities-
