Filter by:Age-related macular degeneration (AMD) is a leading cause of visual impairment in the elderly, characterized by multifactorial etiology. Recent evidence suggests a potential involvement of the gut-retina axis in AMD pathogenesis, prompting exploration into novel therapeutic strategies. The investigators assessed the effects of a micronutrient mix containing lutein, zeaxanthin, and saffron, recognized for their anti-inflammatory properties, on ophthalmological and microbial parameters in neovascular AMD (nAMD) patients. Thirty nAMD subjects were randomized to receive daily micronutrient supplementation along with anti-VEGF therapy or anti-VEGF treatment alone for 6 months. Ophthalmological assessments, anthropometric and biochemical measurements and stool samples were obtained pre- and post-treatment. Gut microbiota (GM) characterization was performed through 16S rRNA sequencing while short (SCFAs), medium (MCFAs) and long (LCFAs) chain fatty acids were analyzed with a gas chromatography-mass spectrometry protocol. nAMD patients exhibited reduced GM alpha diversity, altered taxonomic abundances and decreased total SCFA amount, coupled with elevated proinflammatory octanoic and nonanoic acids. Micronutrient supplementation led to improved visual acuity in comparison to the control group, along with the reduction in the total amount of MCFAs, metabolites exerting detrimental ocular effects. This study reveals compositional and functional imbalances in the GM of nAMD patients compared to healthy controls. Furthermore micronutrient supplementation demonstrated a potential to restore the gut-retina axis, suggesting its therapeutic efficacy in improving ocular outcomes in nAMD patients. These findings underscore the intricate interplay between the GM and ocular health, offering insights into innovative interventions for AMD management
Macular degeneration, also called age-related macular degeneration (AMD), is a leading cause of visual impairment and severe vision loss. AMD is a disease with a multifactorial etiology. The main factors which, associated with the genetic ones, increase the risk of WMD onset are represented by smoking, obesity, hypertension, cardio-vascular diseases, a diet rich in dietary fat and alcohol intake. From an organic point of view, AMD is a disease that affects the macular region of the retina, causing progressive loss of central vision. Retinal cells are characterized by high oxygen consumption. Reactive oxygen species (ROS), such as superoxide anion, hydrogen peroxide and hydroxyl radical are the standard product of cellular metabolism within the mitochondria. Under physiological conditions, ROS are neutralized by a system of antioxidants. In case of cellular metabolism disturbances or insufficiency of the antioxidant system, an excess of ROS can be produced which contributes to oxidative stress, widely described as exerting deleterious effects on cells. The high oxygen requirement and low levels of antioxidant enzymes make the retina extremely sensitive to oxidative stress and more susceptible to cell death. Prevention of neuronal death in the retina becomes a crucial aspect for the management of WMD. The treatment of choice for AMD today is the use of anti-VEGF (Vascular Endothelial Growth Factor) drugs, they are effective for neo-vascular AMD, acting on the inhibition of the angiogenic protein VEGF, which is produced in the retina and induced by hypoxia and other conditions. It is practice, however, to support the integration of nutritional supplements such as zinc, resveratrol, carotenoids such as lutein and zeaxanthin, vitamin E and Omega-3 fatty acids. The aim of this study is to evaluate the efficacy of ozonated oil with high ozonides (HOO) administered orally as gastro-resistant capsules (O3Zone, GS Pharma, Malta), as an integrative and complementary treatment in patients affected by macular degeneration in the possible slowing of disease progression.
The purpose of the study is to assess the safety and efficacy of JWK006 in Stargardt Disease(STGD1). JWK006 is packed by adeno-associated virus vector that expressing ABCA4 gene.
Regeneron Pharmaceuticals developed a single-dose pre-filled syringe (PFS) to deliver 8 mg aflibercept. The PFS is a convenient device that contains the study medication that will be injected in your study eye. A PFS offers a sterile, single dose of study drug within the syringe; this eliminates the need for the retina specialist to prepare the injection syringe from a separate vial. This Phase IIIb study is focused on patients with diabetic macular edema (DME) and neovascular (wet) age-related macular degeneration (nAMD). The main aim of the study is to evaluate if the 8 mg aflibercept PFS allows for successful preparation and administration of 8 mg aflibercept by retina specialists. The study will also assess the safety of 8 mg aflibercept PFS use. Regeneron will use the information from the study to better understand if the PFS can be used safely and effectively by retina specialists to administer 8 mg aflibercept.
This study is a biomarker evaluation study in patients with geographic atrophy secondary to age-related macular degeneration (AMD). The study evaluates microperimetry (fundus-controlled perimetry) and optical coherence tomography imaging for assessing changes in retinal sensitivity and anatomy over time.
Study purpose: To evaluate if previously high-frequent (3-5 weekly) aflibercept treated neovascular age-related macular degeneration (nAMD) can be extended in their treatment interval when switched to faricimab. Primary objective: To assess the efficacy of faricimab compared to aflibercept in terms of durability at 32 weeks by extending treatment interval in previous high-frequent aflibercept treated nAMD.
Phase 2b, randomized, double-masked, parallel-group, active-controlled, multicenter, 36-week study designed to assess the safety and efficacy of suprachoroidally administered CLS-AX 1.0 mg with a flexible dosing regimen in participants with neovascular age-related macular degeneration previously treated with intravitreal anti-vascular endothelial growth factor (VEGF) standard of care therapy. Only one eye will be chosen as the study eye.
The goal of this clinical trial is to understand the safety of AXT107 injected suprachoroidally in participants with nAMD. The main question[s] it aims to answer are: - Safety of the maximum tolerable dose of AXT107 - Bioactivity and duration of action of AXT107 injected suprachoroidally Participants will be injected with AXT107 and will be followed on a regular monitoring visits through 9 months post single injection.
The goal of this study is to evaluate the safety and efficacy of LX102-C01 treatment of nAMD. This study will enroll subjects aged ≥ 50 years old to receive a single unilateral intravitreal (IVT) injection of LX102-C01 to evaluate its safety and efficacy.
The purpose of this study is to determine increases in the Omega Index test indicating optimal Omega-3s particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels for overall systemic benefits including healthy cardiovascular health and cholesterol levels as shown in the OmegaIndex (OmegaQuant) research.
