Intravitreal injection is the method of administration of drugs into the eye by injection with a fine needle. The medication will be directly applied into the vitreous humor. [1] It is used to treat various eye diseases, such as age-related macular degeneration (AMD), diabetic retinopathy, and infections inside the eye such as endophthalmitis. [1]
In 2005 bevacizumab and ranibizumab intravitreal injections for the treatment of wet-AMD caused a rise in injections to 252,000. [2] In 2008, over 1 million intravitreal injections were performed. This doubled to 2 million just 3 years later in 2011 when another anti-VEGF intravitreal injection aflibercept became available for the treatment of ...
A 2017 review update studying the effects of anti-VEGF drugs on diabetic macular edema found that while all three studied treatments have advantages over laser therapy, there was moderate evidence that aflibercept is significantly favored in all measured efficacy outcomes over ranibizumab and bevacizumab, after one year, longer term advantages ...
Diabetic retinopathy (also known as diabetic eye disease) is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
Ixoberogene soroparvovec (Ixo-vec, also known as ADVM-022), is a gene therapy developed by Adverum Biotechnologies for wet age-related macular degeneration. It is delivered via the viral vector AAV.7m8. [1] [2]
Intraretinal microvascular abnormalities (IRMA) are abnormalities of the blood vessels that supply the retina of the eye, a sign of diabetic retinopathy. [1] IRMA can be difficult to distinguish from and is likely a precursor to retinal neovascularization. One way to distinguish IRMA from retinal neovascularization is to perform fluorescein ...
Pegaptanib [2] sodium injection (brand name Macugen) is an anti-angiogenic medicine for the treatment of neovascular (wet) age-related macular degeneration (AMD). [3] It was discovered by NeXstar Pharmaceuticals (which merged with Gilead Sciences in 1999) and licensed in 2000 to EyeTech Pharmaceuticals, now OSI Pharmaceuticals, for late stage development and marketing in the United States.
These anti-VEGF agents may be administered monthly or adaptively. For adaptive anti-VEGF treatment, two approaches are conventionally applied. In the case of pro re nata , the patient comes at fixed intervals, but treatment is only administered if an activity is detected (i.e., presence of fluid).
