Intravitreal anti-VEGF agents – The way forward
The advent of antivascular endothelial growth factor injections... has revolutionized the management of retinal vascular diseases including macular neovascularization (MNV), retinal vein occlusions (RVO), diabetic macular edema (DME), and many other disorders that fall under the gamut of vasculopathies.
Although effective, more work is required to individualize treatment regimens with anti-VEGF injections using emerging technology... Newer drugs with longer duration of action and better safety profiles are required at affordable costs...

Anti-VEGF Therapy: Past, Present, and Future
The introduction of anti-VEGF therapy has had a greater effect on the world of retina than any other advance in the past few decades.
Long-Lasting Anti-VEGF Implants
Care for patients with retinal vascular diseases often includes monthly or bimonthly intravitreal injections. This schedule, combined with possible additional rescue injections and clinic visits for other ocular comorbidities, places a heavy burden on patients.
Anti-VEGF Injections: Start to Finish
Intravitreal injections of anti-VEGF are FDA-approved for a number of ocular conditions and have been shown to decrease macular edema and improve vision. The most common are aflibercept (Eylea), ranibizumab (Lucentis) and bevacizumab (Avastin).
Anti-VEGF Therapy & AMD
While all of these medications have excellent efficacy for the treatment of nAMD, the results of HAWK and HARRIER suggests increased durability of treatment with brolucizumab, with more than 50% of patients achieving 3-month dosing of brolucizumab in HAWK and HARRIER.
Anti-VEGF Therapy: An Ophthalmology Resident's Guide
The main challenge with anti-VEGF injections is concerning treatment burden, as some patients need intravitreal injections up to every 4 weeks. One of the primary goals of current research is to develop different treatment modalities with improved durability but equal safety and efficacy. Recent research focuses on developing implants, extended-release polymers, tyrosine kinase inhibitors, and gene therapies to prolong the time between treatments.
Anti-VEGF-Resistant Retinal Diseases: A Review of the Latest Treatment Options
Anti-vascular endothelial growth factor (anti-VEGF) therapy currently plays a central role in the treatment of numerous retinal diseases, most notably exudative age-related macular degeneration (eAMD), diabetic retinopathy and retinal vein occlusions. While offering significant functional and anatomic benefits in most patients, there exists a subset of 15–40% of eyes that fail to respond or only partially respond.
Current and Future Anti-VEGF Agents for Neovascular Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is the most common cause of legal blindness in developed countries. Neovascular (ie, wet) AMD is currently managed with intravitreal therapy. Traditional treatments (ie, bevacizumab, ranibizumab, aflibercept) provide high-efficacy therapy but can also require frequent dosing.
Emerging Evidence Concerning Systemic Safety of Anti-VEGF Agents – Should Ophthalmologists Be Concerned?
Intraocular injections of anti–vascular endothelial growth factor (VEGF) agents have yielded dramatic improvements in the management of a wide variety of neovascular ocular diseases including age-related macular degeneration (AMD), diabetic retinopathy (DR), retinal vein occlusion, and now even retinopathy of prematurity. These agents have thus become one of the most commonly employed treatments,..
How are these anti VEGF agents different from one another
Anti Vascular endothelial Growth factor (anti VEGF) agents a group of medications which block the activity of VEGF and thus mitigate the abnormal effects of VEGF.
How Do Anti-VEGF Injections Work?
All anti-VEGF medications work to bind the VEGF with protein molecules called aptamers. Aptamers prevent the VEGF from encouraging production of any new abnormal blood vessels.
Saving memories: Do anti-VEGF agents contribute to cognitive loss?
Perhaps you have some alternative hypotheses of your own. Whatever the truth is, I think it is worth examining in greater detail whether anti-VEGF agents might play a role in cognitive loss.
Intravitreal anti-VEGF agents – The way forward
This field of research has constantly evolved with newer drugs and newer treatment regimens such that we are now at the doorsteps for individualized treatments for patients depending on the disease activity.
