Filter by:In this study researchers want to learn more about changes in visual acuity (clarity of vision) with a high dose treatment with Aflibercept (Eylea) in patients suffering from neovascular age-related macular degeneration (nAMD). Neovascular AMD is an eye disease that causes blurred vision or a blind spot due to abnormal blood vessels that leak fluid or blood into the light sensitive lining inside the eye (retina). The fluid buildup causes the central part of the retina (macula) responsible for sharp, straight-ahead vision to swell and thicken (edema), which distorts vision.
To determine safety, pharmacokinetics, and duration of effect of intravitreally administered AIV007 gel suspension in subjects with neovascular age-related macular degeneration
The purpose of this study is to compare two different treatment protocols for wet macular degeneration; the new protocol called "Observe and Plan" against the current standard protocol "Treat and Extend". Studies suggest that patients achieve equally good visual acuity with fewer controls and that they are more satisfied with the new protocol.
In patients treated for exudative age-related macular degeneration (AMD), diabetes, retinal venous occlusion (OVR), or other conditions causing macular edema, treatments with anti-angiogenic intravitreal injections (IVT) are widely used both for their anti-angiogenic action. Patients often have injections for many years, sometimes monthly or every 2 months. The discontinuation of treatment with repeated injections of anti-angiogenic agents, linked to the COVID-19 coronavirus pandemic will potentially impact the visual acuity, the ophthalmological state and the quality of life of the patients concerned, therefore it is relevant to analyze the consequences the breakdown of usual care in this population.
This study is designed for multi-center, open-label, randomized, dose escalation phase I trial to evaluate the safety and tolerability of a multiple dose intravitreal injection of IBI302 in neovascular AMD patients.
Patients with advanced dry AMD with GA meeting inclusion criteria will be randomized in one eye in a 1:1:1 ratio comparing intravitreal high or low dose AAVCAGsCD59 with a sham injection. All enrolled subjects will be followed for 24 months to evaluate reduction in GA growth and safety of intravitreal AAVCAGsCD59.
The hypothesis of this study is to determine if there is a benefit afforded by the use of systemic Sildenafil to patients with choroidal and retinal degenerations and dystrophies, such as vitelliform degeneration, dry and reticular age-related macular degeneration (AMD) as well as patients with hereditary and acquired retinal dystrophies such as retinitis pigmentosa and central serous retinopathy.
The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device.
Background: Age-related macular degeneration is a common eye disease in people over 50. The "dry" form of the disease can worsen into geographic atrophy, causing blind spots. Researchers want to learn if replacing older eye cells with younger ones can help treat this disease. Objective: To test the safety of putting cells inside the eye as a possible future treatment for dry age-related macular degeneration. Eligibility: People ages 55 and older who have geographic atrophy with loss of vision. People who have had "wet" macular degeneration in study eye are NOT eligible. Design: Participants will be screened with: - Medical history - Physical exam - Blood and urine tests - Eye exam - Eye photos - Fluorescein angiography. An intravenous (IV) line is placed in an arm vein. A dye is injected. A camera takes pictures of the dye as it flows through the eyes' blood vessels. - Electroretinography. An electrode is taped to participants' forehead. They sit in the dark. After 30 minutes, numbing eye drops and contact lenses are placed in their eyes. They watch flashing lights. - Tuberculosis test - Chest X-ray - Electrocardiography. Sticky pads are placed on participants' chest to record the heart's electrical activity. Participants will have at least 14 study visits over 5 and a half years. They will repeat screening tests. Participants will have retinal pigment epithelium (RPE) transplantation surgery in one eye. For this, cells from participants' blood are turned into RPE cells. These cells are placed in their eye through a cut in their retina. They will get dilating eye drops, an IV line, and anesthesia that may make them sleep. A gas bubble will be put in their eye to help it heal. Participants will receive immunosuppressive medications to avoid transplant rejection. Participants will be contacted yearly for up to 15 years.
This study is to characterize mitochondrial DNA (mtDNA) populations in adults with eye injuries and eye diseases. The eye exam is often hindered by the clouding of tissues involved in injury or disease. This protocol examines the use of mtDNA populations as indicators of developing inflammation and resolution of injury. This may be used to provide proactive treatment or define appropriate treatment needs beyond the indications of an ophthalmological exam.
