Background: \- To understand diseases of the retina and the eye, information is needed about people with and without such diseases. Researchers want to study these people and follow them over time. They also want to study body tissues and blood to understand the nature of eye disease. Studying genes, cells, and tissues may help them understand why some people get eye problems and others do not, or why some people respond to treatment while others do not. Researchers want to collect physical samples and personal data to develop a National Eye Institute database. Objectives: \- To collect health information and blood and tissue samples from people with and without eye diseases, to be used in research studies. Eligibility: * Individuals at least 2 years of age with different types of eye disease. * Healthy volunteers with no history of eye disease. Design: * Participants may be recruited from National Eye Institute studies or may be referred from other sources. * Participants will be screened with a physical exam and medical history. They will also have a full eye exam. Questions will be asked about family medical history, especially about eye disease. * Blood samples will be collected. Other samples, such as saliva, tears, hair, stool, and urine, may be collected as needed. Adult participants may also provide a skin sample. * Tissue or fluid from eye collected as part of eye care or treatment may also be added to the database. * No treatment will be provided as part of this study.

NCT01866371
Studying the morphology and function of the normal and diseased retina in vivo is needed for advancing the detection, diagnosis, and treatment of retinal disease. This protocol uses an adaptive optics scanning laser ophthalmoscope (AOSLO) to image the normal and diseased retina with individual cellular resolution non-invasively. The primary objective of this study is to obtain and analyze high-resolution images of the retina, in particular by imaging the cone photoreceptor mosaic, the retinal vasculature and other retinal layers. The study design will involve case-control studies, where cases are followed over time. Subjects age 7 and older may be invited to participate. The main research procedure involves retinal imaging with the AOSLO. The primary endpoint is the observation of differences in retinal images between subjects with and without retinal diseases. These changes will be quantified by examining the cell density, size, spacing and regularity of the cone photoreceptor mosaic, as well as examining the differences between other retinal layers.
NCT07567898
The purpose of this research study is to test whether a personalised care approach improves adherence compared to standard care. Many patients with macular diseases like age-related macular degeneration and diabetic macular edema need regular eye injections to protect their vision. However, some do not adhere to their treatment appointments, risking further vision loss. You were selected as a possible participant in this research study because you have been diagnosed with neovascular age-related macular degeneration (nAMD) or diabetic macula edema (DME) requiring intravitreal injection treatment (IVT). This research study targets to recruit 200 participants from the Singapore National Eye Centre. This study comprises two cohort groups: Cohort 1(Suboptimal CAT scores/ Randomized Control trial) and Cohort 2 (Optimal CAT scores/Observation). If you agree to take part in this study, the research coordinator will obtain your written consent before proceeding with the study procedures. You will be required to complete CAT assessment (via remote or administered in clinic) and assigned to cohort 1 or cohort 2 based on CAT scores result. If you are assigned to cohort 1, you will be randomly allocated to either the personalized multi-disciplinary protocolized intervention (MPI) or standard care group. Randomization means assigning you to one of two groups by chance, like tossing a coin or rolling a dice. * MPI group: You will complete a specialized computerized adaptive testing (CAT) quality of life questionnaire. Based on the domain specific scores, you will receive a medical consultation and a referral to nurse educators, optometrists, occupational therapists, or social workers. * Standard care group: If you are allocated to this group, you will receive standard care, where doctors make treatment decisions without using the CAT results. If you are assigned to cohort 2, you will be placed under prospective observation and undergo routine clinical care.

NCT07440225
Researchers are looking for new ways to treat neovascular age-related macular degeneration (NVAMD). Available standard (usual) treatments for NVAMD, such as aflibercept, may not work for every person. Researchers want to learn if a trial medicine called tiespectus (also called MK-8748 or EYE201) can treat NVAMD. The goal of this trial is to learn if tiespectus works as well as aflibercept to treat NVAMD.
NCT05407636
ABBV-RGX-314 (also known as RGX-314 and surabgene lomparvovec (sura-vec)) is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (wet AMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-vascular endothelial growth factor (VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every four to 12 weeks in frequency, to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time. ABBV-RGX-314 is being developed as a potential one-time treatment for wet AMD.
NCT07308639
The main goal of this study is to find out how common certain eye diseases are in Germany and how they have changed over time. The diseases being studied are: nAMD (neovascular age-related macular degeneration): a condition that affects the central part of the retina and can cause vision loss in older adults. DME (diabetic macular edema): a swelling in the central part of the retina caused by diabetes, which can also lead to vision problems. RVO (retinal vein occlusion): a blockage of the veins in the retina, which can cause sudden vision loss. Researchers will look at data collected from 2009 to 2024 to see how often these diseases occur (incidence) and how many people have them at a given time (prevalence). They will use two large sets of health data from Germany, called FDZ and FDGP. The main question is: How do the numbers of new and existing cases of nAMD, DME, and RVO compare between the two data sources (FDZ and FDGP) in Germany from 2009 to 2024? The study also wants to find out if factors like age, other health problems, and medications affect how common these eye diseases are. Another goal is to see how many people with these eye diseases are treated with a type of medicine called anti-VEGF, which is used to slow down or stop vision loss. In summary, this study will help us understand how these eye diseases affect people in Germany, how they are treated, and whether different groups of people are more likely to get them.
NCT07520318
Oculgen has begun a study of an investigational drug called OCUL101 as a possible treatment for neovascular AMD. An investigational drug is one that has not been approved by regulatory agencies, such as the Food and Drug Administration (FDA) in the United States (US), the European Medicines Agency (EMA) in the European Union (EU), or others. A comparator drug, Eylea® (aflibercept), will also be used in this study. Aflibercept is approved by regulatory agencies to treat neovascular AMD. VEGF-A (vascular endothelial growth factor A) is a protein released by the body in response to certain conditions that encourages the eye to form new blood vessels that are weak and leaky. This can lead to leakage of fluid and swelling in the macula; the part of the eye that helps you see clearly. C5 (component 5) is a part of the immune system released when there is ongoing damage to the eye such as when you have neovascular AMD. When it becomes too active in the eye, it can cause inflammation and further damage, leading to thinning of the back of the eye, a condition called geographic atrophy (GA). OCUL101 works by blocking both VEGF-A and C5. The main purpose of this study is to see how safe and tolerable OCUL101 is and how well OCUL101 works in participants when compared with aflibercept. From here on, OCUL101 and aflibercept will be referred to as the "study drug." This study is divided into 2 periods: a screening period and a study treatment period. During each study period, you will have 1 or more visits with your study doctor at the center. The screening visit will last about 3 hours, and all other visits will last about 3 to 6 hours. This study has 2 Parts. Part A uses the 10.4 mg dose of OCUL101 and Part B uses 2 doses of OCUL101 (6.5 mg and 10.4 mg) to compare with 2 mg of aflibercept. Before any study-related tests and procedures can be done, you will be asked to read and sign this informed consent form, and then the study will begin with a screening visit. The purpose of the screening visit is to decide whether or not you meet the requirements to take part in this study. If you do not meet the requirements, the study doctor will explain why and will discuss other treatment options with you. If the study doctor decides that you meet all of the requirements to be in this study, you will be assigned to either Part A or randomly assigned (like drawing straws) to one of the groups in Part B. You will then receive one of the following study treatment plans: * Part A, 10.4 mg of OCUL101 * Part B, Group 1, 6.5 mg of OCUL101 + as needed study treatments of 10.4 mg OCUL101 * Part B, Group 2, 10.4 mg of OCUL101 * Part B, Group 3, 10.4 mg of OCUL101 * Part B, Group 4, 2 mg of aflibercept You will receive 3 injections between Day 1 and Week 8, after which you may or may not receive additional injections every 8 weeks until Week 36. After you receive the set number of injections for your Part/group, you may receive additional injections during the study if the study doctor thinks it will help you. You will have an 80% (4 in 5) chance of receiving OCUL101 and a 20% (1 in 5) chance of receiving aflibercept. This is a double-masked study, which means you and some of the people involved in the study will not be told if you are receiving OCUL101 or aflibercept. However, this information will be given to the study doctor if it becomes necessary for your safety. The eye receiving the study drug is called "the study eye". If the other eye, called the "fellow eye", needs treatment with anti-VEGF therapy, you can discuss this with your study doctor. This treatment may be provided during your study visit, if appropriate. Description of the procedures and assessments * Medical history: Includes questions about any diseases, chronic or ongoing conditions, surgeries, cancer history, reproductive status, and smoking history. Any information about current or previous medicines will also be recorded. * Demographics: Information to be collected includes age, sex, and race/ethnicity. * Physical examination: Physical examination of the chest, abdomen, head and neck, and musculoskeletal system will be done as per your study doctor's preferred methods. * Eye examinations: Throughout the study you will have several eye tests. Both the front and back of your eye will be examined and some of these eye exams may occur in both eyes. Eye drops may be used to make your pupils (center part of your eye) look larger (dilated) and easier to look through. * BCVA: You will sit in front of an eye chart to read the letters and test the sharpness and accuracy of your vision. * Contrast sensitivity: You will sit in front of an eye chart read the letters where the letters are lighter and darker shades. * Color Vision Testing: Your vision will be tested to see how well you see color by having you look at color vision charts. * Assessment of metamorphopsia: Metamorphopsia is when you see lines as wavy or bent instead of straight.
