Glaucoma is a chronic neurodegenerative optic nerve disease. Treatment is intended to prevent the development and progression of optic nerve damage by lowering intraocular pressure (IOP). Current therapy options include topical/systemic drugs that increase aqueous humor outflow or decrease its production, laser therapy that targets the trabecular meshwork and ciliary body, and incisional surgery. Trabeculectomy as well as glaucoma drainage devices are often performed, given their high efficacy in lowering IOP...

Glaucoma following penetrating keratoplasty (PKP) remains the leading cause of blindness following PKP. Patients with post-PKP glaucoma can be managed medically and surgically. Evidence studying glaucoma surgical techniques following PKP is limited, but suggests the possibility for high risk complications, including graft failure. Minimally invasive glaucoma surgeries (MIGS) offer an alternative. We report the first case of post-PKP glaucoma managed with GATT. The patient was a 33-year-old male with a history of keratoconus who underwent PKP in his right eye...

Surgical and laser procedures traditionally used in the management of exfoliation glaucoma (XFG) include laser trabeculoplasty, trabeculectomy, and glaucoma drainage implant surgery. Having demonstrated similar safety and efficacy in XFG compared with primary open-angle glaucoma, trabeculectomy remains the most commonly performed surgery in XFG. Recent trends in practice patterns in developed nations demonstrate a shift towards glaucoma drainage implant surgery, which is currently the procedure of choice in XFG for many, particularly in developed nations...

Steroid-induced ocular hypertension (SIOH) is a challenging entity in paediatric age, with many being refractory to medical therapy. Literature is scarce about surgical options in these cases. A 14-year-old girl with bilateral uveitis and macular oedema had received an intravitreal and subconjunctival triamcinolone injection in the right (OD) and left (OS) eye, respectively. While the steroid was effective in resolving the oedema, intraocular pressure (IOP) increased to about 40 mm Hg OD and 34 mm Hg OS, despite being under maximal IOP-lowering therapy...

Surgical treatment for glaucoma has undergone a dramatic change over the last decade. Trabeculectomy has been the main surgical procedure worldwide for almost 50 years. However, there is a growth in development of new novel devices and surgical techniques designed to lower intraocular pressure in a less invasive fashion. The term minimally invasive glaucoma surgery (MIGS) has been coined and is the subject of investment, debate and, increasingly, research. The position of MIGS in the glaucoma treatment paradigm is yet to be clearly defined and its ability to replace conventional filtration surgery remains debatable...

The recent development of new devices that are significantly less invasive, collectively termed minimally invasive glaucoma surgery, offers new perspective of intraocular pressure reduction with less risk, short operating times, and rapid recovery. The aim of this work is to provide a panoramic review of the currently published clinical data to assess the potential role of XEN gel stent (Allergan PLC, Irvine, CA, USA) in the management of glaucoma, which is the only filtering minimally invasive glaucoma surgery device that allows the subconjunctival filtration...

INTRODUCTION: Primary open-angle glaucoma is estimated to affect 3% of the population aged 40-80 years. Trabeculectomy is considered the gold standard in surgical management of glaucoma; however, it is a technically complex procedure that may result in a range of adverse outcomes. Device-augmented, minimally invasive procedures (micro-invasive glaucoma surgeries, MIGS) have been developed aiming for safer and less invasive intraocular pressure (IOP) reduction compared with traditional surgery...

Positive vitreous pressure due to misdirection of aqueous or choroidal effusion leads to shallowing of the anterior chamber (AC) before or during anterior segment surgeries. This shallow AC if not addressed makes surgery difficult and increases the risk of surgical complications. Methods to prevent and manage this condition described in literature are not without problems. We describe a minimally invasive technique of passing a 30G needle through the pars-plana to aspirate misdirected fluid from vitreous cavity either as a prophylaxis just before surgery or during it, thereby decreasing positive vitreous pressure...

BACKGROUND: The recent advancement in the management of chronic renal failure (CRF) has significantly increased the longevity of the patients, which increase the incidence of severe vitreoretinopathy. The vitrectomy is highly risky in this particular group of patients due to their systemic comorbidity. The timing surgical intervention is usually delayed because of the systemic conditions. This study is to evaluate the safety and effectiveness of 25-guage vitrectomy for severe vitreoretinopathy in the CRF patients...

Noncompliance is a problem affecting glaucoma patients. Approaches to improve adherence include the use of drug-delivery systems and safer forms of surgery. Minimally invasive glaucoma surgery (MIGS) has reduced complications, particularly in combination with cataract surgery, and with its good intraocular pressure (IOP) reduction may reduce or eliminate glaucoma medications.Glaucoma is a progressive disease and a leading cause of irreversible blindness. Elevated IOP is the most important risk factor, but effective medical management is dependent on patient adherence...

Trabeculotomy (LOT) is performed to reduce the intraocular pressure in patients with glaucoma, both in children and adults. It relieves the resistance to aqueous flow by cleaving the trabecular meshwork and the inner walls of Schlemm's canal. Microhook ab interno LOT (µLOT), a novel minimally invasive glaucoma surgery, incises trabecular meshwork using small hooks that are inserted through corneal side ports. An initial case series reported that both µLOT alone and combination of µLOT and cataract surgery normalize the intraocular pressure during the early postoperative period in Japanese patients with glaucoma...
