Glaucoma is a progressive optic neuropathy characterized by retinal ganglion cell death and alterations of visual field. Elevated intraocular pressure (IOP) is considered the main risk factor of glaucoma, even though other factors cannot be ruled out, such as epigenetic mechanisms. An overview of the ultimate promising experimental drugs to manage glaucoma has been provided. In particular, we have focused on purinergic ligands, KATP channel activators, gases (nitric oxide, carbon monoxide and hydrogen sulfide), non-glucocorticoid steroidal compounds, neurotrophic factors, PI3K/Akt activators, citicoline, histone deacetylase inhibitors, cannabinoids, dopamine and serotonin receptors ligands, small interference RNA, and Rho kinase inhibitors...

AIM: To describe the surgical management of glaucoma in a patient with severe scleromalacia, and secondary angle closure. INTRODUCTION: The management of glaucoma with coexisting scleromalacia plus secondary angle closure is challenging as most commonly performed incisional glaucoma surgery as well as minimally invasive glaucoma surgery (MIGS), which targets the drainage angle are all contraindicated. CASE REPORT: Medically refractory glaucoma in a 60-year-old male with a 30-year history of granulomatosis with polyangiitis resulting in extensive severe scleromalacia, cicatricial lower lid retraction with significant conjunctival exposure, and widespread synechial angle closure from chronic anterior uveitis was managed with combined phacoemulsification cataract surgery, and endoscopic cyclophotocoagulation (ECP)...

Steroids are a group of anti-inflammatory drugs, commonly used to treat ocular and systemic conditions. Unmonitored use of steroids especially in eye drop formulations is common in situations when it is easily available over-the-counter, resulting in undesirable side effects. Among the ocular side effects, cataract and glaucoma are common. Steroid-induced ocular hypertension was reported in 1950, when long-term use of systemic steroid was shown to increase the intraocular pressure (IOP). Chronic administration of steroids in any form with raised IOP can cause optic neuropathy resulting in steroid-induced glaucoma...

The term optical coherence tomography angiography (OCTA) comprises different OCT-based technologies which all allow noninvasive assessment of retinal perfusion, based on moving red blood cells. The main areas where OCTA is currently used are investigation of perfusion and vascular structure of the macular retina (e.g., in macular degenerations and diabetic macular diseases) and the disk and peripapillary retina (in glaucoma and other optic disk diseases). The current editorial provides a brief overview on the potential of OCTA and its use to measure perfusion in the peripapillary retina in glaucoma...

Congenital aniridia is a rare panocular disease caused by fundamental disturbances in the development of the eye, characterized primarily by hypoplasia of the iris and the retinal fovea. Severe secondary complications such as keratopathy, cataract, and glaucoma are common and often lead to considerable visual impairment or blindness. Many complications in aniridia patients are difficult to treat and present a challenge for the ophthalmologist. Increasingly, associated non-ocular features of the disease are also being recognised...

Glaucoma is a well-known complication following corneal transplantation surgery. Traditional corneal transplantation surgery, specifically penetrating keratoplasty (PK), has been slowly replaced by the advent of new corneal transplantation procedures: primarily lamellar keratoplasties. There has also been an emergence of keratoprosthesis implants for eyes that are high risk of failure with PK. Consequently, there are different rates of glaucoma, pathogenesis, and potential treatment in the form of medical, laser or surgical therapy...

BACKGROUND: Surgeries are inevitable for treating primary congenital glaucoma (PCG) and risk factors of surgical failure play a key role in surgical decision making. The aim of this study was to investigate the influence of delay of surgery and preoperative speed of progression (SP) on the surgical outcomes in these patients. METHODS: Medical records of 83 eyes of 51 PCG patients with trabeculotomy within 3 years were retrospectively observed. Surgical outcomes, demographic and clinical data were compared after separating the eyes into two groups based on the interval (between onset of PCG and trabeculotomy) and SP index (SPI) respectively...

Zhidong Miao, Dake Liu, Chen Gong
Inductive wireless power transfer (IWPT) is a promising power technology for implantable biomedical devices, where the power consumption is low and the efficiency is the most important consideration. In this paper, we propose an optimization method of impedance matching networks (IMN) to maximize the IWPT efficiency. The IMN at the load side is designed to achieve the optimal load, and the IMN at the source side is designed to deliver the required amount of power (no-more-no-less) from the power source to the load...

Primary open-angle glaucoma (POAG) is often caused by elevated intraocular pressure (IOP), which arises due to increased resistance to aqueous humor outflow (AHO). Aqueous humor flows through Schlemm's canal (SC), a lymphatic-like vessel encircling the cornea, and via intercellular spaces of ciliary muscle cells. However, the mechanisms underlying increased AHO resistance are poorly understood. Here, we demonstrate that signaling between angiopoietin (Angpt) and the Angpt receptor Tie2, which is critical for SC formation, is also indispensable for maintaining SC integrity during adulthood...

Glaucoma is a leading cause of blindness, with an estimated world-wide prevalence of 3.5% in members of the population older than 40 years of age. Elevated intraocular pressure as the result of abnormal resistance to aqueous humor drainage is a major contributing, and the only preventable, factor in glaucoma development. Schlemm's canal (SC), a lymphatic-like vessel encircling the anterior portion of the eye, plays a key role in promoting aqueous humor outflow and maintenance of normal intraocular pressure...
