The purpose of the study is to determine the effect of Intravitreal Aflibercept Injection (IAI) on previously treated Central Retinal Vein Occlusions (CRVOs) with other Anti-VEGF agents.
The purpose of this study was to evaluate the efficacy and safety of brolucizumab in treatment of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO).
The purpose of this study is to compare visual improvement and total number of intraocular injections in eyes with macular edema following central retinal vein occlusion (CRVO)after initial treatment with Ozurdex (dexamethasone implant) or Avastin (bevacizumab).
The purpose of this study is to determine whether ranibizumab (Lucentis) will be effective in reducing if not eliminating the macular edema associated with the disease, central retinal vein occlusion (CRVO).
Eyetech Pharmaceuticals Inc. and Pfizer, Inc. are studying an investigational drug, MacugenTM, for the possible treatment of CRVO. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). This investigational drug may slow the growth of abnormal blood vessels in the eye and may reduce tissue swelling in the eye. The purpose of this study is to compare the safety and efficacy of a Macugen™ injection to a "pretend" injection. In addition, the purpose of this study is to measure the action of the study drug in the body over a period of time and to check for the presence of the study drug in your blood (called pharmacokinetics or PK). This study will involve approximately 90 people. People who decide to participate will have an equal chance (1 in 3) to receive one of three study injections, two of which are Macugen™ and one of which is a "pretend" injection.
This is a phase 3 study to determine the efficacy of VEGF Trap-Eye injected into the eye on vision function in subjects with macular edema as a consequence of central retinal vein occlusion.
This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in patients with macular edema due to central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO).

The objective of the study is to assess the ocular safety of the FYB201 pre-filled syringe in terms of preparation and administration by Retina Specialists in the clinical setting.
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.
The Dexamethasone Posterior Segment Drug Delivery System (DEX PS DDS) Applicator is used to deliver an implant with medicine to the eye. AbbVie is updating the DEX PS DDS Applicator. This purpose of this study is to show that the updated DEX PS DDS Applicator works in adult participants with macular edema due to retinal diseases. The DEX PS DDS is approved for the treatment of macular edema. Participants will be placed into 1 of 2 groups, called treatment arms. Each group receives the same treatment drug delivered using different applicators. Around 54 adult participants with macular edema will be enrolled in the study in approximately 7-10 sites in the United States. Participants will receive a single intravitreal (into the eye) administration of DEX PS DDS implant using either the currently-approved DEX PS DDS Applicator or the the updated Applicator. The participants will be observed for a duration of 7 days, with the DEX PS DDS implant received on day 1 and follow-up through day 7. The updates being evaluated in this study are related to the DEX PS DDS Applicator only, with the safety and efficacy of the DEX PS DDS implant well characterized and the same as the currently marketed product. Participants will attend regular visits during the study at a hospital or clinic. The applicator function will be checked by medical assessment, checking for side effects, procedural complications and/or product complaints, and evaluating the administration procedure.
The purpose of this study is determine the number of patients with complete resolution of macular edema secondary to central retinal vein occlusion following 6 monthly injections of Aflibercept.
CRVO occurs when the vessels in the back of the eye become blocked. This creates a dangerous condition because the vessels are weak and prone to leakage. This results in the development of macular edema. Previous studies have shown that inflammatory mediators and growth factors, such as vascular endothelial growth factor (VEGF), are elevated in patients with macular edema associated with CRVO. Ozurdex® is approved by the Food and Drug Administration (FDA) and is available by prescription for macular edema following CRVO and branch retinal vein occlusion (BRVO). It is also indicated for the treatment of non-infectious uveitis affecting the posterior segment of the eye. The approved dosage is 0.7 mg. Ranibizumab (Lucentis®) is approved by the Food and Drug Administration (FDA) and is available by prescription for other eye disorders, such as wet age-related macular degeneration (AMD), macular edema following CRVO or BRVO, and diabetic macular edema (DME). The approved dosage for wet AMD and macular edema following CRVO/BROV is 0.5 mg given monthly. The approved dosage for DME is 0.3 mg given monthly. Dr. Gonzalez is conducting an investigational study on the safety and effectiveness of treating CRVO-associated Macular Edema with a combination of 0.7 mg of Ozurdex® and 0.5 mg Lucentis®, given as separate injections into the eye.
To see if Lucentis 0.5mg combined with Targeted Pan Retinal photocoagulation will decrease the total number of intravitreal injections in a year for ischemic central retinal vein occlusion, hemi-retinal vein occlusions and branch retinal vein occlusions compared to standard of care
Central retinal vein occlusion (CRVO) is a common cause of vision loss, typically affecting individuals during the fifth through seventh decade of life. Eyes with severe CRVO have a poor visual prognosis because current treatments address only secondary complications of CRVO without treating its cause. Intra-ophthalmic artery injection of a small dose of t-PA (clot busting medicine), also called intra-ophthalmic artery thrombolysis, may reopen the central retinal vein-and address the cause of the disease- without exposing the subject to the risks of systemic thrombolysis. Our project aims to evaluate the safety and efficacy of intra-ophthalmic artery thrombolysis in subjects with CRVO.
This study examines two doses of Ranibizumab (0.5mg and 1.0mg) for the treatment of macular edema secondary to retinal vein occlusion in patients that have previously failed treatment with other macular edema treatments including bevacizumab.
The purpose of this study is to determine whether a fluocinolone sustained drug delivery implant is effective in the treatment of central retinal vein occlusion that has caused persistent macular edema and decreased visual acuity.
The use of intravitreal injections of corticosteroid (triamcinolone acetonide) appears to be a promising treatment for a variety of ocular diseases associated with inflammation. To date, the only drug available, "Kenalog-40 Injection" produced by Bristol Myers Squibb, has not been formulated for intraocular use. The purpose of this study is to evaluate the long-term safety and potential efficacy of novel intravitreal injections of a preservative-free formulation of triamcinolone acetonide (TAC-PF) at two dosage levels (4 mg and 8 mg) compared to anterior sub-tenon injections of TAC-PF at 20 mg. The study will be a masked, randomized Phase I study that will enroll 120 participants with one of the following diseases: age-related macular degeneration (AMD), diabetic macular edema (DME), central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), or any other retinal disease with associated macular edema. At least 21 participants will be enrolled in the four designated disease strata: AMD, DME, CRVO, and BRVO. The remaining 36 participants may have one of these diseases or may be enrolled with another retinal disease. Within each disease strata, at least seven participants will be randomized to each dosing group. The participants will be randomly assigned to one of the three treatment groups. The primary outcome will be an assessment of post-injection intraocular toxicity-related events during the 3-year follow-up, including cataract formation, development of glaucoma, and any adverse event preventing retreatment. The secondary outcomes will be an improvement in best-corrected visual acuity (BCVA, EVA) and decreases in retinal thickening and area of leakage, from baseline to year 1.
The SCORE Study will compare the effectiveness and safety of standard care to intravitreal injection(s) of triamcinolone for treating macular edema (swelling of the central part of the retina) associated with central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO).
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.
This interventional study will evaluate the retinal vascular dynamics associated with Intravitreal Aflibercept Injection (IAI) therapy in eyes with diabetic macular edema (DME) or macular edema secondary to retinal vein occlusion (RVO). Ultra-widefield fluorescein angiography and optical coherence tomography (OCT) angiography will be performed at multiple timepoints to assess the changes in retinal vascular leakage, ischemia, and vascular abnormalities throughout the study duration and compare these alterations to baseline.
Since 2004, intravitreal injection of Avastin, Lucentis, and Macugen for wet age-related macular degeneration, retinal vein occlusion, and diabetic macular edema are being administered in the United States at increasing rates. A 2010 study showed that in Canada and the incidence of injections grew 8 fold from 2005 to 2007 to 25.9 injections per 100,000 citizens. (Campbell 2010) In 2009, in the United States, over 1 million intravitreal injections were administered to Medicare beneficiaries. (Wykoff 2011) In the year 2011, the four doctors in my retina group administered a total of 6,494 intravitreal injections; in 2010, we administered 5021 intravitreal injections. Even though intravitreal injections are commonly administered, the optimal method of anesthetizing the eye prior to injection has yet to be determined. Some physicians use an anesthetic drop, some a soaked cotton pledget, some use an anesthetic gel and some use subconjunctival injected anesthetic. In 2009, the last time the Procedures and Trends Survey (PAT) (Mittra 2009) conducted by the American Society of Retina Specialists (the largest retina society in the world) asked about anesthetic methods for administering intravitreal injections, the following response was given by the 433 respondents: * Topical anesthetic drop: 21.48% * Topical viscous anesthetic: 23.33% * Topical anesthetic \& soaked cotton-tip or pledget: 29.79% * Subconjunctival injection of anesthetic: 24.02% * Other: 1.39% An editorial in 2011 in the journal Retina, discusses the lack of good studies assessing optimal anesthetic prior to intravitreal injections. (Prenner 2011).
Researchers are looking for a better way to treat people who have macular edema secondary to retinal vein occlusion (RVO). In people with RVO, a blood vessel that carries blood away from the retina (vein) becomes blocked. The retina is the very back part of the eye. The blocked vein causes fluid and blood to leak into the retina and thereby causes a swelling of the macula (the center of the retina responsible for fine vision). This swelling is called macular edema. When a vein in the retina is blocked, the levels of a protein called vascular endothelial growth factor (VEGF) rises. VEGF helps the growth of new blood vessels. This can lead to macular edema and may cause the vision to become blurry. The study treatment intravitreal (IVT) aflibercept is given as an injection into the eye. It works by blocking VEGF and this can help repair vision problems related to RVO. IVT aflibercept is already available and is prescribed by doctors as the standard of care treatment for macula edema secondary to RVO. Standard of care is a treatment that medical experts consider most appropriate for a disease. Standard of care is given every 4 weeks in people with macula edema secondary to RVO. While repeated injections of aflibercept may prevent worsening of vision, it may place a burden on the patient. However, a higher amount (8 mg) compared to the standard of care (2 mg) of IVT aflibercept is being tested in studies. This higher amount could be given less often. The amount of IVT aflibercept given is measured in milligrams, also known as mg. The main purpose of this study is to learn how well a higher amount of the study treatment aflibercept works in people with macular edema secondary to RVO. To answer this, researchers will measure changes in vision called best corrected visual acuity (BCVA) in the study participants between study start and after 36 weeks of treatment. Changes will then be compared between those participants who received the higher amount of IVT aflibercept and those that received standard of care. To learn how safe the study treatment is in the participants, the researchers will count the number of participants from study start and up to 64 weeks later that have: * adverse events * serious adverse events "Adverse events" are any medical problems that the participants have during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think they might be related to the study treatments. An adverse event is considered "serious" when it leads to death, puts the participants' lives at risk, requires hospitalization, causes disability, causes a baby being born with medical problems or is otherwise medically important. Dependent on the treatment group, the participants will either receive the higher amount of aflibercept or standard of care as an intravitreal injection for up to 60 weeks. The study will consist of a test (screening) phase, a treatment phase and an end of study phase. Each participant will be in the study for up to 64 weeks. One visit to the study site is planned during the screening phase, followed by visits approximately every 4 weeks (16 in total) during treatment and one visit at the end of the study. During the study, the study doctors and their team will: * check patients' eye health using various eye examination techniques * measure patients' eye vision (BCVA) * take blood and urine samples * do physical examinations * check vital signs * examine heart health using electrocardiogram (ECG) * do pregnancy tests in women of childbearing age In addition, participants will be asked to fill a questionnaire on vision-related quality of life.
