Anti-VEGF therapy in India has fundamentally altered the management of retinal vascular disorders over the last two decades. Traditionally, laser photocoagulation was the primary treatment for conditions like diabetic macular edema. However, the discovery of Vascular Endothelial Growth Factor as a central driver of neovascularization changed clinical practice. Early agents like pegaptanib paved the way for more potent molecules. Furthermore, the development of ranibizumab and aflibercept provided clinicians with highly effective tools to preserve vision and improve patient outcomes.
The Indian healthcare landscape presents unique economic challenges for patients requiring long-term retinal care. Consequently, the high cost of innovator biologics often limits treatment adherence in many cases. To address this, India pioneered the use of biosimilar ranibizumab to improve affordability. These biosimilars offer similar efficacy and safety profiles compared to their reference products. Moreover, they significantly reduce the financial burden on families. In addition, off-label bevacizumab remains a widely used, cost-effective alternative in many clinical settings across the country.
Clinicians must maintain strict safety standards when administering intravitreal injections. Specifically, monitoring for endophthalmitis and intraocular pressure spikes is essential. Newer bispecific antibodies like faricimab now offer the potential for extended dosing intervals. This advancement may reduce the treatment burden for patients with age-related macular degeneration. Ultimately, providing high-quality retinal care requires a balance between innovation and equitable access for the diverse Indian population.
The most common agents include ranibizumab, aflibercept, brolucizumab, and faricimab. Additionally, biosimilar ranibizumab and off-label bevacizumab are frequently utilized due to cost considerations.
Biosimilars have made advanced retinal therapy more accessible to a larger segment of the population. By reducing the price of therapy by 35% to 50%, they help improve long-term treatment compliance for chronic conditions.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
