Thyroid associated ophthalmopathy (TAO) is a common autoimmune disorder. The pathogenesis of TAO is unclear, and studies found that T cell, B cell and monocytes, macrophages and mast cells are located in the orbital tissue of TAO. Dysthyroid optic neuropathy (DON) is the most serious complication of TAO, which can cause blurred vision, color vision and vision function damage, and affects the quality of life. Investigation of the therapeutic effect of orbital decompression may p...
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 a...
Non-arthritic anterior ischemic optic neuropathy is the most common cause of sudden visual loss due to optic nerve involvement in patients above 50 years old. As this problem can be considered as a sclera out let syndrome an there is no effective and successful treatment for it, we decided to do a neurotomy procedure and relax the involved optic nerve in order to achieve acceptable treating outcome.
After introducing intravenous erythropoietin (EPO) as an option for treatment of patients with indirect traumatic optic neuropathy in 2011 and publishing non inferiority trial in Oct.2017), TONTT2 is aiming to find out the best dose and timing of EPO administration in this group of patients.
To follow all patients enrolled in the original Ischemic Optic Neuropathy Decompression Trial (IONDT) to determine (1) the incidence of non-arteritic ischemic optic neuropathy (NAION) in the second eye, (2) changes in visual acuity over time in both the study and second eye, and (3) other aspects of the natural history of NAION.
The purpose of this study is to explore the safety and efficacy of ranibizumab to treat non-arteritic ishemic optic neuropathy based on clinical and anatomical findings.
To assess the safety and efficacy of optic nerve sheath decompression surgery for non-arteritic ischemic optic neuropathy (NAION).
Anterior ischaemic optic neuropathy results from infarction of retrolaminar portion of the optic nerve head, caused by occlusion of the posterior ciliary artery. Non arteritic anterior ischaemic optic neuropathy affects more frequently people between 50 and 70 years of age, with vasculopathic risk factors. Arteritic anterior ischaemic optic neuropathy is caused by the Horton disease, affects an older population and is an ophthalmologic emergency because of the bilateralisation'...
Correction of the deficit in the perfusion pressure of the microcirculation that supplies the nerve by intravenous infusion of Prostaglandin E1 (PGE1) (Alprostadil), expected to improve visual function in patients with ischemic optic neuropathy previous non-arteritic (NOIANA).
This study is meant to evaluate the safety and efficacy of rAAV2-ND4 treatment for Leber hereditary optic neuropathy with the G11778A mutation in mitochondrial DNA.
The investigators tested the hypothesis whether the treatment with Citicoline in oral solution (OS-Citicoline) would increase or stabilize visual acuity, retinal ganglion cells (RGCs) function and neural conduction along the visual pathways (neuroenhancement), and/or induce preservation of RGCs fibers' loss (neuroprotection) in an human model of neurodegeneration: non-arteritic ischemic optic neuropathy (NAION).
Non-Arteritic Ischemic Optic Neuropathy (NAION) is a disease producing swelling of the optic nerve (the "cable" going from the eye to the brain) resulting in decreased vision. About 15% of patients will experience NAION in the second eye; many of these patients will be left legally blind. Currently, there is no treatment for NAION and for patients in whom the second eye becomes involved by the disease the outcome can be devastating. The investigators are conducting a...
Ischemic optic neuropathy is among the most common causes of serious impaired vision in the middle-aged and elderly population in the western world. The current study focuses on a subgroup of ischemic optic neuropathy, the so-called non-arteritic ischemic optic neuropathy (NAION). Although the exact pathogenesis of NAION has not been fully clarified it is known that patients with cardio-vascular risk factors such as hypertension, diabetes mellitus and dyslipidemia have also an ...
Expanded Access Use for a single patient of Bilateral Intravitreal Injection of GS010 in a Single Subject Affected with G11778A ND4 Leber Hereditary Optic Neuropathy
This study is meant to assess the safety and efficacy of rAAV2-ND4 treatment of Leber hereditary optic neuropathy with 11778 LHON mutation.
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
Study H6D-MC-LVHQ is an observational, non-interventional, multi-center, prospective, case-crossover study to evaluate the possible association between the use of phosphodiesterase type 5 (PDE5) inhibitors and the risk of acute nonarteritic anterior ischemic optic neuropathy (NAION) in males. Subjects with newly diagnosed NAION will be asked via a structured questionnaire about their use of PDE5 inhibitors and other risk factors prior to the onset of their vision loss.
The use of the femtosecond laser causes an increase in the intraocular pressure (IOP) between 100 mm Hg and 200 mm Hg for a period of about 80 seconds (suction phase). If it is known that elevated IOP accelerates the degradation of retinal ganglion cells, whose axons form the optic nerve. No data has been published to date on potential adverse effects of femtolaser cataract surgery performed in patients with glaucomatous optic neuropathy. Since some time, spectral-doma...
The purpose of the study is to evaluate the effect of N-acetyl cysteine in combination with paclitaxel on the clinical outcomes of patients with peripheral neuropathy, paclitaxel-induced peripheral neuropathy affect quality of life in cancer patients. new therapeutic approches such as the antioxidant N-acetyl cysteine, showed to has neuroprotective effect, the aim of the study is to evaluate the effect of N- acetylcysteine(NAC) administration in the prevention of paclitaxel-In...
This study is designed to treat patients with Graves' disease with Rituximab in an attempt to prevent or reverse the physically deforming and debilitating consequences of this disease.
The purpose of this survey is to collect visual acuity data from patients with LHON in order to establish the clinical course (natural history) and visual acuity outcomes in patients with a genetically confirmed diagnosis of LHON. In addition, this survey will generate data that will serve as comparator for the open-label study SNT-IV-006.
This is a Phase 2, prospective, randomized, double-masked, vehicle controlled, single-center study in approximately 12 subjects with LHON to evaluate safety, tolerability and efficacy of MTP-131 ophthalmic solution in this patient population.
This study is designed as a double-masked, randomized, placebo-controlled, pivotal, clinical study to evaluate the efficacy and safety of subcutaneous (SC) administration of RPh201 in participants with previous NAION. All participants enrolled in the study will have a documented history of NAION for at least 12 months and at most, five years prior to enrollment.
A single arm, single center trial to assess the safety and efficacy of restoring function in damaged optic nerves using autologous purified populations of bone-marrow derived stem cells (BM-SCs) through a 24 month follow up period.
Background Leber's Hereditary Optic Neuropathy (LHON) is a maternally inherited ocular disorder associated with a mutation in mtDNA . The common manifestation is visual loss which caused by the respiratory chain enzymes complex dysfunction resulting in increased oxidative stress enzymes production. Purpose To determine whether curcumin which is an antioxidant agent is beneficial to the patients with 11778 LHON mutation. Material and Method Seventy patients with 1177...
