Low intraocular pressure and hypotony secondary to overfiltration is a recognized complication after trabeculectomy, particularly when augmented with antimetabolites such as 5-fluorouracil and mitomycin C. The relatively recent introduction of minimally invasive glaucoma surgery such as the ab interno XEN 45 (Allergan, Ireland) subconjunctival gel implant has heralded a new era of glaucoma drainage surgery where postoperative complications may be less and surgical recovery quicker. However, any effective glaucoma filtering procedure will always carry the risk of inducing hypotony...

REVIEW
Jed Lusthaus, Ivan Goldberg
Glaucoma is an irreversible progressive optic neuropathy, for which the major proven treatment is to lower the intraocular pressure (IOP). Five groups of IOP-lowering eye drops have varying mechanisms of action. Some drops, such as β-blockers and α-2 agonists, have potentially serious systemic side effects. Acetazolamide is the only available oral agent; it is effective at lowering IOP, but significant side effects relegate its use usually to refractory glaucoma. Two new eye drops, netarsudil and latanoprostene bunod, have recently been approved by the United States Food and Drug Administration...

H Burkhard Dick, Tim Schultz, Ronald D Gerste
In the management of glaucoma, recent and upcoming innovations have the potential to contribute to both the efficacy of intraocular pressure (IOP) monitoring and the number of available treatment options. These new devices and procedures have two things in common: they are part of the trend in medicine towards miniaturization, and they require a limited surgical procedure to become effective. This review focuses on the Eyemate (Argos) intraocular sensor, which offers a new way to reliably measure 24 h IOP, and on intraocular sustained release systems for pharmacological glaucoma therapy...

The goal of all glaucoma surgery is to lower eye pressure to prevent or reduce damage to the optic nerve. Standard glaucoma surgeries - trabeculectomy, ExPRESS shunts and external tube-shunts like the Ahmed and Baerveldt valves - are major surgeries. While they are very often effective at lowering eye pressure and preventing progression of glaucoma, they have a long list of potential complications. Minimal invasive glaucoma surgery (MIGS) is a group of operations that have been developed in recent years to reduce some of the complications of most standard glaucoma surgeries...

A 78 old male with angle closure glaucoma and on treatment with oral anticoagulants, underwent phacoemulsification. An early acute suprachoroidal hemorrhage (SCH) occurred and the surgical wound was rapidly sutured without complete soft lens matter (SLM) removal, nor insertion of intraocular lens (IOL). The SCH was managed conservatively and it resolved in 5 weeks; the intraocular pressure was 35▒mm Hg despite maximal medical treatment. Secondary SLM removal followed by IOL implantation combined with XEN45 was then performed...

Minimally invasive glaucoma surgery for chronic open-angle glaucoma treatment tries to reduce the amount of chronic topical drug treatment, delaying invasive glaucoma surgery and diminishing the number of surgical complications. XEN45 uses subconjunctival drainage in order to reduce intraocular pressure. The report is presented of a patient following phacoemulsification, intraocular lens implantation and XEN45 implant. After four days acute malignant glaucoma was observed, with stage 3 athalamia requiring pars plana vitrectomy and secondary Ahmed valve implantation...

REVIEW

PURPOSE OF REVIEW: It is well known that glaucoma patients are not adherent to their therapeutic regimens. The issue of nonadherence is multifactorial and includes inadequate communication between doctors and patients, resulting in significant costs associated with enhanced disease progression. Therapeutic regimens are risk factors which often influences adherence rates. Thus, alternative treatment modalities, especially those risk factors that do not rely on patients' cooperation, may enable improvements in long-term outcomes of glaucoma in patient...

BACKGROUND: Glaucoma is a leading cause of irreversible blindness. Subconjunctival draining minimally-invasive glaucoma devices such as the Xen gelatin implant and InnFocus stent have been introduced as a treatment to prevent glaucoma progressing.These implants provide a channel to allow aqueous humour from the anterior chamber of the eye to drain into the subconjunctival space on the surface of the eye thus reducing intraocular pressure (IOP) and mimicking the mechanism of the most commonly undertaken glaucoma surgery, trabeculectomy...

INTRODUCTION: Primary congenital glaucoma is a rare ocular disorder that is responsible for 0.01%-0.04% of total blindness worldwide.1 The goal of congenital glaucoma management is to allow for proper development of the immature visual system by controlling intraocular pressure. Medical therapy usually provides a supportive role to temporarily reduce intraocular pressure, but patients typically require iridocorneal angle surgery to facilitate aqueous humor outflow. In this report, we describe the use of minimally invasive ab interno Kahook Dual Blade trabeculectomy for treatment of primary congenital glaucoma...

In recent years, minimally-invasive glaucoma surgery has emerged as a novel approach to lowering intraocular pressure (IOP). This technique, which is usually reserved for mild to moderate cases, is less invasive than classic filtration surgery and potentially offers a better safety profile. The XEN Gel Stent is implanted through a minimally-invasive, ab interno procedure to create a subconjunctival pathway. Conjunctival tissue disruption is minimal and flow is restricted to avoid hypotony. Data on the optimal approach to managing complications associated with this procedure are limited due to the relatively recent commercialization of this device...
