Filter by:This study is designed as a double-masked, randomized, placebo-controlled, clinical study to evaluate the efficacy and safety of subcutaneous (SC) administration of RPh201 in participants with previous NAION. All participants enrolled in Cohort A of the study will have a documented history of NAION for at least 12 months and at most, five years prior to enrollment. Participants enrolled in Cohort B of the study will have a documented history of NAION for at least 6 months and at most, three years prior to enrollment.
The objective of this trial is to assess the efficacy and safety of CNM-Au8 as a remyelinating treatment for vision-impairing MS lesions in participants who have chronic vision impairment as a result of Relapsing-Remitting Multiple Sclerosis. The primary endpoint is to assess the efficacy and safety of CNM-Au8 as a remyelinating therapy in patients with stable RMS. The secondary endpoint is Change in Functional Composite Responder Analysis Score from Baseline to Week 24.
The participant is being asked to be a subject in this research study because the participant may have a disorder that can cause optic nerve damage and impairment of his/her visual function which is called optic neuropathies (ON). Optic neuropathy refers to damage to the optic nerve (a "cable" connecting the eyes and the brain to transmit the visual signals) due to any cause.In this study, the investigator is using magnetic resonance imaging (MRI) and ophthalmic measures such as optic coherent tomography(OCT), which are non-invasive imaging tests to measure the changes in eye globe shape ,the flow of blood and brain fluid. It is hoped that this study will provide new knowledge that may allow the investigator to better understand the cause of symptoms associated with optic neuropathy and ways to better monitor what is happening.
This study plans to learn more about the thickness of the choroid in patients with optic neuropathy. The choroid is a layer of blood vessels that supplies oxygen and nourishment to the outer layers of the retina. Patients are being asked to be in this research study because they have optic neuropathy and are receiving care at the University of Colorado Hospital.
This study will determine the effect of QPI-1007 on visual function in subjects with recent-onset NAION and assess the safety and tolerability of intravitreal injections of QPI-1007 in this population. This study will also evaluate the structural changes in the retina following administration of QPI-1007.
At present, trabeculectomy is the most common performed and effective surgical method of filtration surgery for patients with medically uncontrolled glaucoma. The aim of this prospective observational case study is to determine changes of the peripapillary retinal nerve fiber layer thickness using spectral domain optical coherence tomography in patients with glaucoma after surgical reduction of intraocular pressure.
The overall objective of the proposed research is to test the hypothesis that Near-infrared Light-emitting Diode (NIR-LED) therapy will stimulate mitochondrial function, attenuate oxidative stress, and improve cell survival and vision in subjects with Leber's Hereditary Optic Neuropathy (LHON).
The primary objective of this study is to determine whether the use of PDE5 inhibitors (vardenafil, sildenafil, or tadalafil) increases the risk for the development of NAION.
To understand and characterize the effects of linezolid on the optic nerve by observing and following patients who have been treated with linezolid for six weeks or longer for the development of signs or symptoms of visual disturbance or eye disorders.
