A calipers-free intravitreal anti-VEGF injection technique

Abstract

Técnica de injeção intravítrea de anti-VEGF sem compassoDear Editor, Intravitreal injection of drugs such as anti-vascular endothelial growth factor (anti-VEGF) agents and corticosteroids has shown encouraging results in the treatment of many ocular diseases. In developed countries, this type of injection is probably the most frequently performed vitreoretinal procedure. However, it has the potential for serious complications, such as endophthalmitis, lens injury, and retinal detachment (1) . To avoid these unfortunate complications, it is important to assess the safety and cost-effectiveness of intravitreal injection. A safe, cost-effective, calipers-free intravitreal injection technique is presented here.The patient is placed in the supine position in the operating room. The skin, lids, and lashes are sterilized using 10% povidone iodine, and
