Filter by:In this study, markers of oxidative stress will be measured in the aqueous humour of stargardt disease, age related macular degeneration and diabetic retinopathy patients compared to controls.
This is a feasibility study to assess the use of wide field adaptive optics optical coherence tomography (WF-AO-OCT) to determine whether there are structural differences in the peripheral retina in participants diagnosed with diabetic retinopathy compared to a healthy control group. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the WF-AO-OCT light source is well below maximum permissible limits for safe exposure.
The present study is intended to evaluate the efficacy and safety of topical OC-10X Ophthalmic Suspension in patients diagnosed with proliferative diabetic retinopathy (level 61, 65, 71, or 75). OcuCure Therapeutics, Inc. (Roanoke, VA) has developed a lead compound, known as OC-10X, which is a selective tubulin inhibitor under development for the treatment of Proliferative Diabetic Retinopathy (PDR) and Age-related Macular Degeneration (AMD). When administered as a topical eye drop, OC-10X has both anti-angiogenic (inhibition) and angiolytic (regression) properties in animal models of choroidal neovascularization (CNV). Unlike other therapies, OC-10X provides the efficacy of a vascular targeting agent without the traditional toxicity and works downstream independently of growth factors. As demonstrated by OcuCure's preclinical data, tubulin inhibition, using OC-10X, may be a promising new approach to the treatment of PDR and AMD. Like AMD, PDR is a major cause of blindness in adults and is also caused by the growth of abnormal blood vessels. Importantly, the Phase I Study found that OC-10X can be safely applied topically in human eyes without adverse ocular or systemic effects. Currently, there are few options for the treatment of PDR. Clinical options, such as laser photocoagulation or vitrectomy, require surgery and can permanently impair patients' vision. With few treatment options available, administration of OC-10X as a topical therapy, along with its novel mechanism, has the potential to provide benefits to patients with ocular diseases associated with angiogenesis.
The purpose of this study is to assess the efficacy and safety of up to 3 intravitreal injections of ocriplasmin (0.0625mg or 0.125mg), in subjects with moderate to very severe non-proliferative diabetic retinopathy (NPDR), to induce total posterior vitreous detachment (PVD) in order to reduce the risk of disease progression to proliferative diabetic retinopathy (PDR).
The objective of this study is to image retinal vascular alterations in patients with retinal disease using the AngioVue OCT-A system and understand the information these images provide. The investigators will image study participants who have retinal diseases with the AngioVue unit (Optovue) and will collect relevant clinical data to understand the nature of the information contained in images obtained on AngioVue. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the AngioVue light source is well below maximum permissible limits for safe exposure.
In this study, the investigators aim to use light masks (Noctura 400) to test the hypothesis that preventing the dark adaptation and associated hypoxia of the rods in the eye could in turn prevent or halt the progression of centre-involving Diabetic Macular Oedema (DMO). DMO is a devastating disease that is the most common cause of registerable blindness in the working age-group in the United Kingdom (UK) This is a multi-centred randomised controlled trial involving 240 patients. Post randomization, participants in the intervention arm will wear the Noctura 400 Light Mask at night for 48 weeks in conjunction with their routine, prescribed treatment of intravitreal (eye) ranibizumab. Those in the standard arm will receive their routine, prescribed ranibizumab treatment only. The primary objective is to determine whether utilizing the Noctura 400 Light Mask at night reduces the number of intravitreal injections of ranibizumab required by patients undergoing such a course for the treatment of DMO.
The purpose of this study is to evaluate the role of alpha lipoic acid in patients who have moderate non-proliferative diabetic retinopathy. The primary aim of this study is to test the hypothesis that the addition of alpha lipoic acid in a diabetic patient's therapeutic regimen can decrease the progression of diabetic retinopathy and preserve visual acuity.
The purpose of this study is to determine whether phase variance optical coherence tomography (PV-OCT), a software-based optical coherence tomography(OCT) image processing technology, can be used to generate angiographic images of the retinochoroidal vasculature that are comparable to those produced by fluorescein angiography (FA), the current gold standard diagnostic test.
To show the non-inferiority of EGRIFTA® vs. placebo in the development or progression of Diabetic Retinopathy in HIV-infected subjects with concomitant abdominal lipohypertrophy and Type 2 diabetes mellitus (T2DM).
The pilot study evaluates the efficacy and safety of Canakinumab (ILARIS®) in subjects with proliferative diabetic retinopathy secondary to type 1 and 2 diabetes. Ten subjects will be enrolled to receive 150 mg Canakinumab (ILARIS®) by subcutaneous injection. Beginning on day 0, each subject will receive a subcutaneous injection of study drug every 8 weeks for 16 weeks, a total of 3 injections. All subjects will undergo regular follow-up assessments every 8 weeks through 24 weeks. Fluorescein angiography (FA) is repeated every 8 weeks. In case of progression of retinal neovascularization on FA panretinal laser photocoagulation is administered as rescue therapy. The primary outcome is the regression of retinal neovascularizations (NVE and NVD) in FA at 24 weeks. In addition to key secondary outcomes including regression of diabetic macular edema, change in best-corrected visual acuity, change in HbA1c levels and change in markers of systemic inflammation. Safety will be assessed by measurements of vital signs, clinical laboratory assessments, and the recording of adverse clinical events.
