EYE-TIE-201 is a 2-part study to investigate the safety and effectiveness of a new drug being developed called EYE201. All participants in the study will receive a total of 3 injections of EYE201 into the study eye, spaced at 4 weeks apart. In the first part, termed the multiple ascending dose (MAD) portion of study, the safety of EYE201 will be assessed at increasing doses in branch retinal vein occlusion (BRVO) participants. Approximately 12 participants will be entered in this part of the study. In the second part of the study, called the dose finding part, 2 doses of EYE201 will be selected and their effectiveness will be compared. This portion of the study assesses the safety and preliminary efficacy of EYE201 in patients with diabetic macular edema (DME) or neovascular macular degeneration (NVAMD). Approximately 80 participants will be entered in this part of the study.
This study is researching aflibercept high dose (HD), referred to as "study drug", with an experimental dosing regimen. The study is focused on participants with nAMD and DME that have been previously treated with anti-vascular endothelial growth factor (anti-VEGF) medications. The aim of the study is to see how safe and effective aflibercept HD injections are when given as frequently as every 4 weeks. The study is also looking at what side effects may happen from taking the study drug.

EYE103-101 is a 2-part study assessing safety and preliminary efficacy of EYE103 in patients with diabetic macular edema (DME) given as monotherapy or neovascular macular degeneration (NVAMD) given in combination with anti-VEGF. In the first part, termed the multiple ascending dose (MAD) portion of study, the safety of EYE103 will be assessed at escalating doses. Approximately 12 participants will be entered in this part of the study. In the second part of the study, called the dose finding part two doses of EYE103 will be selected and their effectiveness will be compared. Approximately 80 participants will be entered in this part of the study.
This is a Phase 1/2, open-label, dose-escalation clinical study, enrolling 21 subjects in one of the two treatment groups to determine the effects of topical ocular administration of low dose or high dose MTP-131 given twice a day in subjects with Diabetic Macular Edema and Age-Related Macular Degeneration.
The purpose of this study is to determine the effect of enhancements to the myVisionTrack® in regards to patient compliance and test-retest variability. Additionally, the ability of myVisionTrack® to detect changes in vision function will be evaluated.
The purpose of this clinical trial is to compare safety, tolerability, efficacy, and durability of two dose levels of suprachoroidal sustained-release OXU-001 (dexamethasone microspheres; DEXAspheres®) using the Oxulumis® illuminated microcatheterization device compared with intravitreal dexamethasone implant (OZURDEX®) in subjects with diabetic macular edema.
The primary objectives of this study were to evaluate the safety and efficacy of LKA651 in patients with macular edema from diabetic macular edema (DME),
The purpose of this study is to test DS-7080a, a monoclonal antibody, as a new treatment for neovascular age-related macular degeneration (AMD) and diabetic macular edema (DME). The hypothesis of the study is that DS-7080a is safe and shows preliminary efficacy in patients with these conditions either alone or in combination with ranibizumab. This study is organized into 3 Parts: Part 1 Dose Escalation in AMD participants, Part 2 Dose Expansion in AMD participants, and Part 3 Dose Expansion in DME participants. In Part 1, participants will be enrolled into 3 sequential, ascending dose-level cohorts in non-randomized uncontrolled manner with the main purpose to determine the recommended dose. In Part 2, participants will be randomized to 1 of 3 arms of either monotherapy with DS-7080a or monotherapy with ranibizumab, which is an active control, or combination therapy of DS-7080a plus ranibizumab (ranibizumab will be administered 30 minutes prior to DS-7080a). In Part 3, subjects with DME will be assigned to 1 of 2 arms of either monotherapy with DS-7080a or monotherapy with ranibizumab. DS-7080a or ranibizumab will be administered 3 times: on Baseline/Day 1, Day 29, and Day 57. Both Parts 2 and 3 will consist of 8 visits including a 14-day screening phase, an 84-day treatment period, and a 28-day follow-up period.
Injections of medicine into the middle of the eye (intravitreal injections) are commonly used in a multitude of retinal diseases. We are looking for new treatments that may be beneficial in treating retinal disease and improving patients' vision. Infliximab (Remicade) is a genetically engineered antibody against a molecule in the body called TNF-α. It neutralizes the effects of TNF-α by binding to it. Intravenous Infliximab has been used for inflammatory arthritic conditions and Crohn's disease since 1998. We do not know if infliximab injections into the eye are safe. We are performing this pilot study to determine if they can be safe.
The long-term goal is to show that retinal transplantation can help to prevent blindness and to restore eyesight in patients with dry age related macular degeneration.
This study will compare the side effects of two laser treatments for diabetic macular edema, a common condition in patients with diabetes. In macular edema, blood vessels in the retina, a thin layer of tissue that lines the back of the eye become leaky and the retina swells. The macula, the center part of the retina that is responsible for fine vision may also swell, causing vision loss. Traditional laser treatment (argon blue or green or yellow) for macular swelling, or edema, causes scarring that can expand and possibly lead to more loss of vision. Studies with a different type of laser (diode) may be less damaging. The results of this study on side effects of the treatments will be used to design a larger study of effectiveness. This study will also examine whether celecoxib (Celebrex® (Registered Trademark)), an anti-arthritis drug that reduces inflammation and swelling, can reduce inflammation and swelling of the retina. Patients with elevated cholesterol levels will be invited to participate in a cholesterol reduction part of the study to compare normal-pace cholesterol reduction with accelerated reduction. Patients 18 years of age and older with type 1 or type 2 diabetes and macular edema that requires laser treatment may be eligible for this study. Candidates will be screened with the following tests and procedures: * Medical history: to review past medical conditions and treatments. * Physical examination: to measure vital signs (pulse, blood pressure, temperature, breathing rate) and examine the head and neck, heart, lungs, abdomen, arms and legs. * Eye examination: to assess visual acuity (eye chart test) and examine pupils, lens, retina, and eye movements. The pupils will be dilated with drops for this examination. * Blood tests: to measure cholesterol, blood clotting time, hemoglobin A1C (a measure of diabetes control), and to evaluate liver and kidney function. * Eye photography: to help evaluate the status of the retina and changes that may occur in the future. Special photographs of the inside of the eye are taken using a camera that flashes a bright light into the eye. From 2 to 20 pictures may be taken, depending on the eye condition. * Fluorescein angiography: to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. Participants will be randomly assigned to take celecoxib or placebo (an inactive, look-alike pill). Participants who have elevated cholesterol levels may return for a brief visit after 1 month. All patients will return for follow-up visits at 3, 6, and 12 months. Patients who require laser treatment will be randomly assigned to one of the two laser treatments. For these procedures, eye drops are put in the eye to numb the surface and a contact lens is placed on the eye during the laser beam application. Several visits may be required for additional laser treatments. The maximum number of treatments depends on how well the treatment is working. Patients who respond well to the study medication may receive no laser treatments. After the first year, patients will be followed every 6 months until either the patient returns for a 3-year visit, the last enrolled patient returns for the 1-year visit, or the patient requests to leave the study. During the follow-up visits, patients' response to treatment will be evaluated with repeat tests of several of the screening exams.
The efficacy of laser photocoagulation treatment for diabetic retinopathy has been demonstrated by several National Eye Institute (NEI) sponsored clinical trials. The Diabetic Retinopathy Study (DRS) demonstrated that scatter photocoagulation reduces the risk of blindness from diabetic retinopathy. The Early Treatment Diabetic Retinopathy Study (ETDRS) extended these findings by providing information on when to initiate scatter photocoagulation and by demonstrating that focal treatment was effective in treating macula edema. The Krypton Argon Regression Neovascularization Study (KARNS) showed that scatter photocoagulation with krypton red laser was just as safe and effective as the argon blue-green laser in the treatment of proliferative diabetic retinopathy. Unfortunately, there is little data on the long term effects of photocoagulation on visual function. The first objective of this study is to assess the long term effects of photocoagulation for diabetic retinopathy. A second objective is to provide additional information on the risk of progression of cataracts in persons with diabetes. All patients previously treated with laser photocoagulation (focal and/or scatter) are eligible to participate in this long term study. The first priority will be given to patients who participated in the ETDRS and KARNS because of the wealth of information available regarding the details of their treatment and course after treatment. Study evaluations will include a standard ophthalmic examination, fluorescein angiography, lens and fundus photography.
The purpose of this study is to evaluate possible mechanisms of central visual loss in patients with diabetes mellitus. The visual loss of interest to be investigated is that associated with macular edema (prior to and following laser photocoagulation treatment) and that associated with panretinal photocoagulation. The evaluation will be performed with psychophysical testing, i.e., static perimetry and contrast sensitivity function. Of particular interest, the mechanisms of visual loss associated with macular edema (prior to and following laser photocoagulation) will be further investigated. Photoreceptor-mediated visual loss will be assessed by measurements of the Stiles-Crawford effect. Visual loss mediated by post-receptoral retinal changes will be assessed by measuring the Westheimer spatial desensitization/sensitization effect.
The purpose of this research study is to evaluate an investigational system that may allow doctors to show images of the different parts inside the eye that show greater detail than current equipment can produce.
The goal of this randomized, parallel-group, controlled trial is to compare methods of enhancing linkage-to-care for participants in the Village Integrated Eye Worker II (VIEW II) trial who are referred to the eye hospital following eye disease screening. Participants who are referred to the hospital at an eye screening visit will be randomized to three different linkage-to-care interventions: (1) text message reminders, (2) reminders from community health workers, or (3) no intervention. The primary outcome of the trial will be whether or not the participant presented to the eye hospital for a referral visit by 21 days following screening.
The goal of this observational study is to assess the reliability and validity of the 9-object MLSDT for evaluation of participants with moderate to severe vision impairment when tested without a wearable low-vision magnifying aid (eGlasses) and then with eGlasses. These results will be compared to ETDRS testing results for the same participants without eGlasses and then with eGlasses. Two cohorts will consist of participants who have vision loss due to STGD or geographic atrophy (GA) due to age-related macular degenerations (AMD). Normally sighted participants will provide a control group.
The objective of the study is to assess the ocular safety of the FYB203 pre-filled syringe in terms of preparation and administration by Retina Specialists in the clinical setting.
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.
Background and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort. Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.
In this study, participants will be imaged using two Optical Coherence Tomography (OCT) devices: device N, a standard conventional OCT device with an invention (comfortable chin and forehead rest that can be adjusted to fit each individual's size) attached to the device; and device C, the standard conventional OCT device with no invention attached. The investigators will assess whether the chin and forehead rest attachment (invention) provides a more comfortable experience for patients.
The VOYAGER study is a primary data collection, non-interventional, prospective, multinational, multicenter study. It is designed to collect real-world, long-term data to explore long-term effectiveness, safety, clinical insights, treatment patterns, and factors driving the treatment decisions among patients being treated with specified Roche ophthalmology products in approved retinal indications (Faricimab for neovascular age-related macular degeneration \[nAMD\], diabetic macular edema \[DME\], and retinal vein occlusion; Port Delivery System with Ranibizumab for nAMD) in routine clinical practice. This study will not provide or make recommendations on use of any products including Roche products; treatment decisions will be determined by the treating physician and must be made independently to the decision to participate in this study. Participation in this study will not change or influence a patient's standard of care in any way.
