This is an interventional treatment trial for Open Angle Glaucoma Read More

Inclusion Criteria:

• Patient must be 18 years of age or older.
• Patient shall suffer from primary open angle glaucoma, pseudo-exfoliative glaucoma, or refractory POAG or PEXG after previous failed filtering surgery, in the study eye. Diagnosis is based on glaucomatous optic neuropathy, Shaffer angle greater than 2 as seen on gonioscopy, and visual field defect attributed to glaucoma.
• Eye to be treated shall be phakic or pseudophakic with no other active ocular disease or disorder except for incipiens cataract. Prior ophthalmic surgery in the study eye shall have been performed more than 3 months before enrollment in this study.
• Patient condition is indicated for primary and secondary filtration surgery.
• Presence of elevated intraocular pressure defined as an intraocular corrected pressure (IOP) > 20 mmHg in the study eye, under maximally tolerated medications. The IOP level shall be obtained on 2 consecutive measurements (not taken on the same day) prior to surgery.
• Optic neuropathy is exclusively attributed to glaucoma.
• Patient agreed to sign the written inform consent prior to entering into the investigation.
• Patient is able and willing to complete post-operative follow-up requirements.

• History of previous intraocular surgery in the study eye referring to but not limited to extraocular muscles (strabismus), corneal transplant, retinal surgery.
• Proliferative or severe non-proliferative retinopathy in either eye.
• Congenital anomaly of the anterior chamber angle in the study eye.
• Optic neuropathy other than glaucoma in the study eye.
• Patient with retinal vein occlusion in the study eye.
• Patient with retinal artery occlusion in the study eye.
• Patient with corneal opacifications, endotheliopathy, or irregularities that may interfere with the optic nerve evaluation or the IOP measurements in the study eye.
• Patient with a history of severe eye trauma in the study eye.
• Patient with ocular malformations such as microphthalmia in the study eye.
• Patient with concurrent inflammatory/infective eye disorder in the study eye.
• Patient with severe systemic disease or disabling conditions such as chronic renal failure, post organ transplants.
• Patient participating in another clinical trial or having participated in another clinical trial less than 3 months prior to entering into the investigation.
