Filter by:Current methods of detecting glaucoma and monitoring its progression over time involve visual assessment of the optic nerve, thickness measurements of nerve tissue in the eye (using optical coherence tomography, OCT) as well as functional tests which measure peripheral, or side, vision. The objective of this study is to determine if a new technique of measuring blood flow in the eye, using OCT, can be used to better detect and/or monitor changes in glaucoma patients and suspects than these methods.
Evidence of a relationship between age at discovery of congenital glaucoma and visual acuity at 4 years of age. The delay in diagnosis is a factor of poor visual acuity. Will justify the implementation of information programs with health and education professionals in order to improve the functional prognosis of patients with congenital glaucoma.
Glaucoma is the second cause of blindness worldwide. Laser peripheral iridoplasty (LPI) is a simple and effective treatment for angle closure glaucoma. LPI can widen or reopen an existing angle close or angle adhesion in order to reduce the risk of attack of the angle closure glaucoma. However, there are very little research on the laser site, laser wavelengths, laser energy and laser spot intervals. The purpose of this study is to determine the optimum laser wavelengths of LPI.

Few publications provide information on the natural history of glaucoma, outside of clinical trials do not always reflect what is observed in common situation for various reasons (specific selection criteria and sometimes restrictive, stronger motivations patients and physicians to comply with follow-up visits and prescribed treatments, etc.). Therefore, much information on the natural history of glaucoma are unknown to date (degradation rate of visual field and visual function over time, risk of blindness in the years following diagnosis, effects of various treatments to reduce intraocular pressure and preserving visual field deterioration, etc.). Obtaining such important data to improve the management of glaucoma patients (choice of treatment methods, identification of predictors of rapid change that can make choosing more aggressive treatment and more regular monitoring, etc.) requires the establishment of cohort of patients followed and treated with the methods usually used in current practice, and besides therapeutic trial.
This is a randomized, sham controlled, masked clinical trial of 60 study participants with glaucoma. Participants with a qualifying study eye will be randomized after screening and baseline evaluations to receive the NT-501 encapsulated cell therapy (ECT) implant or a sham surgery (control arm), and no explant will be required. An examination for safety will occur one day and one week following implant and periodically thereafter for 24 months post-implant. Based on the primary analysis of data at 6 months, patients in the control arm may be offered the NT-501 ECT implant at the 12 month time point.
STARflo is a novel suprachoroidal Glaucoma Drainage Device (GDD), bleb-free, exhibiting anti-fibrotic properties. Release of this CE Marked implant has been limited to leading Glaucoma Centers in Europe.
This study is to evaluate the ability of a newly designed device, Optic Nerve Glass (O-Glass) to detect relative afferent pupillary defect (RAPD). In this prospective observational study, 44 patients (diagnosed RAPD- positive) enrolled the study. Three groups of masked examiners observed patients for an RAPD by swinging flashlight method (SFM) and O-Glass. The instrument captured and recorded eye pictures. The images were processed and analyzed using computerized software to calculate pupillary measurements. The results were compared between two methods and three different groups of examiners. Twenty six patients were known cases of multiple sclerosis related optic neuritis, fourteen of them had glaucoma and four patients had history of traumatic optic neuropathy. The mean age (SD) of the study participants (18 female and 26 male) was 35. All three groups of examiners were satisfactory with successful diagnosis by O-Glass. Conclusion: O-Glass is a simple eye-glass along with mobile friendly software that any care giver can use to perform the tests to identify a RAPD automatically and rapidly. The ability to store and archive the objective and quantifiable results for referencing and follow-ups, makes the device more valuable.
To compare the intraocular pressure (IOP) and number of glaucoma medications lowering of microinvasive glaucoma surgery (MIGS) with the implantation of the trabecular device Hydrus (Ivantis) as a solo procedure and 360° selective laser trabeculoplasty (SLT) to treat primary open angle glaucoma (POAG).
Glaucoma is a major cause of irreversible blindness worldwide, caused by retinal nerve cell (RGC) death. This is currently identified only after significant vision loss has already occurred with an early event in, and a potential marker of, this process being RGC "apoptosis" (a form of cell death). This study aims to investigate the tolerability and safety of ANX776, as part of the new Detection of Apoptosing Retinal Cells (DARC) technique. This has been developed by the laboratory of DARC IP holder and grant applicant: Prof. M. Francesca Cordeiro. A secondary aim is to initially establish the ability of DARC to identify RGC apoptosis in the diagnosis of glaucoma in healthy and progressive glaucoma/glaucoma-suspect/ocular hypertensive patients. As a positive control for this secondary aim of this study, patients with Non-arteritic Anterior Ischaemic Optic Neuropathy (NAION) will be recruited. During the study, each patient will undergo several ophthalmological examinations, imaging of the back of the eye using established clinical devices, and blood sampling for studying the safety and toxicology profile of ANX776. The understanding of the safety profile of ANX776 is crucial for the use of DARC in patients, and its application as a potentially powerful new clinical tool with which to identify patients with early glaucoma before their vision is lost. If successful, it opens the door to directly observing effects of glaucoma treatments, including the assessment of new, breakthrough therapies.
