•CMJAH eye clinic adult patients (18 years of age or older)
•Bilateral open angle glaucoma (primary open-angle glaucoma (POAG), exfoliation glaucoma (XFG) or pigment dispersion syndrome (PDS)) requiring surgery to both eyes:
•oGLAUCOMA DIAGNOSIS will be based on the appearance of the optic nerve head, open angles on gonioscopy, optical coherence tomography (OCT) structural assessments and humphrey visual field changes
•oREQUIREMENTS FOR SURGERY:
•?IOP greater than 18mmHg despite maximal tolerated medical therapy
•?Progression of optic nerve cupping, thinning of the retinal nerve fibre layer or progression of visual field defects despite maximal tolerated medical therapy

•Post-traumatic and angle-recession glaucoma
•Neovascular glaucoma
•Uveitic glaucoma
•Occludable angles on gonioscopy
•Previous intra-ocular surgery other than uncomplicated cataract surgery
•Prior conjunctival surgery or pathology
•Active inflammation (blepharitis, conjunctivitis, keratitis, uveitis)
•Impaired episcleral venous pressure (for example Sturge-Weber syndrome, nanophthalmos or thyroid eye diseases
