Active clinical trials for "Glaucoma"

Glaucoma is the leading cause of irreversible blindness worldwide. The visual function of patients with advanced glaucoma is severely impaired, and the vision-related activities (e.g. movement, reading) are obviously restricted, which may have a negative impact on the patients' quality of life (QOL) and increase the burden on individuals and families. Low vision aids (LVAs) and other devices for vision rehabilitation (VR) are useful for patients with advanced glaucoma to maximize the function of residual vision and improve the QOL. OXSIGHT smart glasses are the latest LVAs eyeglasses that are expected to improve the QOL for patients with low vision (LV), such as those with glaucoma. Clinical data were collected to evaluate the efficacy and its influencing factors of OXSIGHT smart glasses in patients with advanced glaucoma, in providing theoretical basis for subsequent clinical studies.

The purpose of this study is to assess the long-term safety of the Glaukos® iStent® Trabecular Micro-Bypass Stent Model GTS100 in conjunction with cataract surgery vs. cataract surgery only, in subjects with mild to moderate open-angle glaucoma.

This is a prospective, observational, single-center study. Patients with at least 3 months of experience using topical medications for glaucoma and who state that they administer their own eye drops will be recruited. Subjects will be videotaped instilling a sterile artificial eye drop, will be identified at the time of a regularly scheduled exam. If the patient can get a drop onto the eye and also not touch their lids or ocular surface with the eye drop bottle, the subject will be thanked but not enrolled. All other patients who agree to participate will be enrolled. Upon completion of videotaped instillation of an eye drop, each enrolled patient will be shown a video demonstrating an instillation technique and will be given an instructional handout highlighting a proper drop instillation technique. If necessary, an instillation technique will be demonstrated to them by an investigator or trained personnel. A patient will be identified as properly instilling a drop if they satisfy the following criteia: They are able to instill one (and only one) drop to the ocular surface or lower fornix without allowing the bottle touch the adnexa, eyelid, eye lashes or eye. All patients routinely return between 3 and 6 months. At this regularly scheduled visit,the investigator or trained personnel would direct the patient to instill an eye drop into the study eye.Additionally, the short glaucoma self-efficacy questionnaire will be re-administered. All of the video-recordings of participants' eye drop instillation techniques will be reviewed and assessed using a standard checklist. Their ability to administer an eye drop after training will be compared to baseline.

The purpose of this study is to compare Selective laser trabeculoplasty (SLT) and topical medications for initial treatment of open-angle glaucoma /Ocular Hypertension based on intraocular pressure reduction, treatment side effects, quality of life measures and costs in South Indian Population.

Lasers are important therapy in glaucoma. They are a pivotal point in treatment between medical and surgical care. Over the last 10 years a new laser has emerged as the usual laser treatment: Selective laser trabeculoplasty (SLT). SLT works as well as the older laser used: argon laser trabeculoplasty (ALT). However SLT has many theoretical benefits over ALT including causing less damage to the tissue it affects. One of the potential patient centered benefits of this laser is that it may be repeatable. It is even possible that the old laser ALT may be useable after an SLT treatment. This study aims to uncover whether repeat laser is possible after SLT and if so which laser is more effective (ALT vs SLT). The potential of repeating laser therapies may delay surgical treatment and its complications. Also understanding which laser to use will help eye doctors know how to treat their patients at this point of the disease.

It is a comparative study of Safety and Efficacy of Canaloplasty and Non-penetrating Deep Sclerectomy Combined With Phacoemulsification to Treat Glaucoma and Cataract. It is a Randomised, Prospective Study.

The study has the purpose to evaluate the effectiveness and safety of the goniocurettage as a first choice of surgical treatment for primary open-angle glaucoma (POAG) in patients with good vision.

To prove that external contact micropulse diode laser trabeculoplasty (EMDLT) can significantly lower intraocular pressure in cases of advanced open angle glaucoma.

The investigators aim to demonstrate the efficacy and safety of subconjunctival injection of Avastin as an adjunctive therapy for Ahmed valve glaucoma implant in patients with refractory glaucoma.

Hypothesis: Studies suggest that patients with low diastolic velocity and high resistivity index in the ophthalmic artery had more progressive visual fields, the investigators hypothesize therefore that addition of Cosopt to Latanoprost could improve ocular diastolic perfusion pressure (ODPP). Objective: To evaluate the effects of Cosopt on ODPP in patients not adequately controlled with latanoprost alone.
