Filter by:The neovascular glaucoma (NVG) is a refractory type of secondary glaucoma and often lead to frustrated treatment and blindness. It has been confirmed high levels of vascular endothelial growth factor (VEGF) in NVG. Conbercept is an anti-VEGF agent，its role in regression of other neovascular disorders such as wet-type age-related macular degeneration and diabetic retinopathy has been described. Investigators aim to evaluate the efficacy and safety of intracameral and intravitreal injection of conbercept for the treatment of NVG.
To evaluate the safety and efficacy of the XEN® Gel Stent in mild to moderate glaucoma patients undergoing glaucoma surgery.
The purpose of this study was to determine the incremental intraocular pressure (IOP) lowering that is achieved when Simbrinza is used adjunctively to Travatan in patients with normal tension glaucoma that may benefit from further IOP lowering.
Purpose: To report the follow-up data for patients who had XEN45 gel stent implantation, a new method of minimally invasive glaucoma surgery (MIGS). Material and Methods: Fifteen eyes of fifteen patients who had XEN45 gel stent implantation surgery were investigated in the study. All the patients were examined preoperatively and at the following postoperative time points: 1 day; 1 and 2 weeks; and 1, 2, 3, 6, and 12 months. Intraocular pressure (IOP) was measured by Goldmann applanation tonometry. Combined surgical procedures (XEN 45 + phacoemulsification + intraocular lens) were performed in the cases that had cataracts in addition to glaucoma.
The main objective of this research is to study the cognitive and cerebral mechanisms of the integration of central and peripheral visual information during normal and pathological aging (ophthalmological patients with AMD and glaucoma) through fMRI studies. To assess the effect of normal aging, research will be conducted on a group of young participants with normal vision and a group of elderly participants with normal vision. Each participant will be assessed once during an MRI (during which the brain activity and behavioral performance will be measured). In order to evaluate the effect of pathological aging, research will be conducted on AMD patients, glaucomatous patients, and age-matched controls (normal vision), evaluated only once during an MRI examination.
Safety and tolerability of three different concentrations (0.1%, 03%, 0.6%) of the investigational SHP639 eye drops will be evaluated in participants with high eye pressure or primary open-angle glaucoma.
Lowering of the pressure in the eye (intraocular pressure, IOP) is the only proven treatment for Primary Open-angle Glaucoma (POAG). However, even effective reduction of IOP by pharmacological or surgical means does not always change the course of the disease or prevent the onset of glaucoma. Some people with POAG also suffer from Obstructive Sleep Apnoea (OSA), an increasingly common sleep disorder which is known to affect heart and blood vessels, and may contribute to glaucoma progression. OSA is treated with Continuous Positive Airway Pressure (CPAP); however using this type of breathing support may raise IOP. This study aims to establish whether a short-term application of CPAP in awake subjects leads to an increase in IOP. Patients with treated POAG, patients with newly diagnosed untreated POAG and control subjects without glaucoma will be included. CPAP will be applied at several different pressure levels for a total of 2 hours during which IOP and ocular perfusion pressure (OPP) will be measured. If CPAP is shown to raise IOP or alter OPP it could be necessary to assess available alternative treatment options for OSA.
This study will compare the glaucoma day-ward patients' efficacy with inpatients by evaluating the glaucoma knowledge and psychology , and will analysis the reasons of the differences. Half of participants will receive treatment in day-ward, while the other half will receive treatment in hospital.
This study evaluates the results of all clinically relevant findings of glaucoma diagnostics 5 Years after stent-implantation concerning the safety and effectiveness of the cypass stent procedure. The comparison of Preoperative and long term postoperative results is the aim of this study to evaluate this young procedure of Glaucoma surgery
Glaucoma is the leading cause of irreversible blindness worldwide. It is caused by damage to the optic nerve between the back of the eye and the brain leading to progressive blindness. The cause is poorly understood but ageing, increased intraocular pressure (IOP) and genetics are all likely to play a role. There is no cure for glaucoma but treatments are available which slow progression. Because vision cannot be restored once lost, early detection, monitoring and early treatment are all essential to preserve visual function. The condition is diagnosed using a combination of the appearance of the optic nerve on clinical examination or photograph and visual field testing (perimetry). Measurement of IOP and measurement of the thickness of the retinal layers at the back of the eye complement diagnostic decisions. The Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA) study does not include perimetry in the series of tests carried out on all participants but does include photography of the optic nerve, measurement of IOP and measurement of retinal thickness. Therefore we propose to invite back participants of the NICOLA study who have abnormal optic discs and high eye pressure to return for perimetry to confirm a diagnosis of glaucoma. Calling back participants for perimetry is essential to make the diagnosis not only for estimating prevalence but also for identifying participant's ill-health. The primary aim of this study is to quantify the number of participants in the NICOLA study who have glaucoma and report its risk factors. This will allow an estimate of the number of people in the whole of NI with glaucoma. We will also perform a series of novel tests using state-of-the-art technologies to assess if they are better than current tests at diagnosing glaucoma. This may enable better informed decisions about policy decisions in eyecare.
