Active clinical trials for "Optic Nerve Diseases"

Comparison of high-resolution optical coherence tomography (High-Res-OCT) to conventional imaging modalities for the diagnosis of eye diseases

This study intends to establish a registry cohort to enroll patients with high myopia to study the natural course of myopic optic neuropathy in Chinese adult population.

Leber's hereditary optic neuropathy (LHON) is a rare mitochondrial genetic disorder characterized by optic nerve atrophy due to the degeneration of retinal ganglion cells, which leads to acute visual loss. Males are more likely to develop optic neuropathy than women. They experience blurring or clouding of vision in one eye. The fellow eye develops similar symptoms sequentially with a delay of weeks. This sudden vision loss has devastating consequences on the life course of young men, with the impact of LHON on their quality of life and loss of independence. Yet, data describing the impacts of LHON on the life-course of patients is lacking, with very little data available in the literature. This study aims to understand the life of patients living with LHON disease through the analysis of the impact of LHON on the quality of life and loss of independence of patients living in France and to accurately describe the consequences of the disease on their social, familial and professional life.

The impact of glaucomatous optic neuropathy on the daily life of patients is poorly characterized and does not benefit from standardized tests. The development and validation of new tests could be used to assess the efficacy of innovative treatments for visually impaired patients and/or optimize management strategies.

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 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).

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.

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.

Group 4a and 4b was an FDA trial that showed that patients who have an Amsler grid abnormality on paper, have a similar abnormality on the app. Group 7a and 7b was an FDA trial that showed that normal patients do not have false positives on the Amsler app as well as on the Amsler paper version. Further Vision on the app is slightly better than vision on the standard Sloan near card using a formula (vision is 7/10th of a line better on the app).

This study is meant to assess the safety and efficacy of rAAV2-ND4 treatment of Leber hereditary optic neuropathy with 11778 LHON mutation.
