Glaucoma is a blinding optic neuropathy that affects 60 million people worldwide. Of all the types of existing glaucoma, primary open-angle glaucoma is the most common etiology. The therapeutic arsenal today includes drug lowering treatments, lasers and surgery. The most frequent glaucoma surgeries are, in France, trabeculectomy and non-perforating deep sclerectomy (NPDS). These are two filtering surgeries whose principle is to lower the intra ocular pressure (IOP) by creating an evacuation path of the aqueous humor from the anterior chamber (AC) of the eye to the space subconjunctival creating a filtration bubble (FB). These two procedures are currently considered the gold standard. They can be performed alone or at the same time as cataract surgery. The short-term complications encountered with these techniques are early hypotonia and its attendant complications (choroidal detachment, hypotonic maculopathy, hemorrhages, etc.), the most common cause of which is conjunctival leakage from the bubble. In the medium term, increases in blood pressure with deep AC testify to a scleral flap that is too tight which may require suture lysis. Finally, the problems of excessive conjunctival-Tenon healing concern 25 to 30% of those operated on and are responsible for the majority of late blood pressure increases. In the longer term, the most common complication is cataracts; the rarest, but most serious complication is infection of BF, which occurs more readily when the walls of the FB are ischemic or even perforated. It can be complicated by an extremely serious endophthalmitis. A new minimally invasive therapeutic option has been developed limiting per- and post-operative complications. Unlike traditional techniques which present an ab externo approach, the ab interno approach of the new technique proposed consists of the implantation of a tube of collagen 6 mm in length and 45 µm of light called Xen® through the AC .

This single-center, prospective study will assess safety and effectiveness of 360 degree viscodilation followed by up to 360 degree trabeculotomy used in patients with early or moderate open-angle glaucoma in a real-world setting either as a standalone procedure in pseudophakic patients (or phakic) or combined with phacoemulsification cataract procedures. Medication usage, IOP and secondary surgical procedures necessary for IOP control will be analyzed during the follow-up period.

Laser endoscopic cyclophotocoagulation (ECP) has been in use for the treatment of glaucoma for over 20 years and is usually used in conjunction with cataract surgery. In the US it is one of the most commonly performed cataract 'plus' surgeries. The take-up of ECP laser has been much lower in the UK and Europe. This is partly due to the lack of robust clinical evidence from randomised controlled trials to justify its use in routine practice. More recently the advent of minimally invasive glaucoma surgery techniques (MIGS) has increased the options available for cataract 'plus' surgery. Without any randomised controlled trial data for the use of ECP laser in this context the increasingly popular use of MIGS devices, such as iStent (the current market leader) may further marginalise the use of ECP laser for cataract 'plus' surgery in patients with Primary Open Angle Glaucoma (POAG) and visually significant cataract. To further evaluate the use of ECP laser for the treatment of glaucoma in patients with glaucoma and cataract, investigators plan to conduct a randomised controlled trial comparing cataract surgery alone versus cataract surgery plus ECP laser surgery. Investigators will compare the efficacy of these interventions for the treatment of glaucoma based on clinical outcomes and also undertake a cost-benefit analysis, taking into account the cost of surgery, any reduction in clinical time allocation for procedures, the frequency of intra- and post-operative complications, and any reduction in the need for topical glaucoma treatments post-surgery, as well as the frequency with which further glaucoma filtering surgery is needed for patients in each group. Investigators anticipate that a total number of 160 patients (80 in each arm) will be adequate to detect whether there is any difference in efficacy between cataract surgery + ECP versus cataract surgery alone. Recruitment is expected to take around 9-12 months. Participants will undergo treatment wash-out (28 days minimum) of any eye drops they use for their glaucoma prior to data collection at baseline (before surgery) and prior to data collection at one-year and at two-years post-surgery. Results will be reviewed during an interim analysis at 6 months once 50 patients have reached that time point.

Primary Open Angle Glaucoma (POAG) is an eye disease that causes optic nerve damage, visual field defect, and blindness caused by increased intraocular pressure. In recent years, many studies have shown that ginkgo biloba extract has a protective effect on the visual function of glaucoma patients. Studies have shown that Ginkgo biloba capsules can improve the visual field damage of glaucoma controlled by intraocular pressure;Ginkgo biloba capsule can promote the recovery of visual evoked potential of glaucoma controlled by intraocular pressure; the improvement of visual field has a certain correlation with visual electrophysiological recovery. The mechanism may be achieved by suppressing the influx of calcium ions and thereby inhibiting the apoptosis of cells. Therefore, in this clinical study, effect of Ginkgo biloba capsule on visual function of primary open-angle glaucoma with blood stasis syndrome was evaluated by placebo as control.

Glaucoma is the second leading cause of blindness and the first leading cause of irreversible vision loss worldwide. The intraocular pressure (IOP) is the only modifiable risk factor for all the spectrum of glaucoma. Reducing IOP in glaucoma increases the likelihood of preventing progression of the disease and preserving the quality of life of the patient. Although prostaglandin analogs (PGAs) and prostamides (PMs) are de facto first-line treatment options for managing glaucoma, it is a common clinical experience to see their treatment effects plateau to a level beyond which no clinically significant IOP reduction is likely. It is also common to find minimal IOP treatment effects in the following conditions: patients with normal tension glaucoma (NTG), patients with thicker central corneal thickness (CCT), and patients with higher levels of corneal hysteresis (CH). CH is a possible proxy for the ability of the scleral tissue around the optic nerve to dissipate energy away from the optic nerve fibers. Netarsudil, a rho-kinase inhibitor was recently approved by the FDA for the treatment of glaucoma and ocular hypertension. There is a paucity of research on the efficacy of netarsudil in patients with NTG, thicker CCT, and higher levels of CH. This study aims to investigate the above issues by evaluating the efficacy of netarsudil and bimatoprost in subjects with NTG, thicker corneas, and higher levels of CH. Hypotheses Netarsudil will have non-inferior efficacy compared to Bimatoprost in treating NTG. Corneal thickness and corneal hysteresis will reduce the efficacy of netarsudil similar to bimatoprost in NTG. Netarsudil will change corneal thickness and corneal hysteresis similar to bimatoprost in NTG.
