This video demonstrates the technique in intravitreal anti-VEGF injection. Pupil should be mid-dilated to visualize tip of the needle to avoid lens touch, retinal injury or suprachoroidal injection. Preoperative antibiotic application should be started 3 days prior to intravitreal injection. Thorough wash of ocular surface is done with saline and 5% povidone iodine is applied. Intravitreal triamcinolone acetonide injection is taken in an 1mL tuberculin syringe with 26G needle. In phakic case, it is introduced through pars plana area 4 mm away from the limbus. Tip of the 30 G needle should be well-visualized with beveled tip up directed towards the center of the vitreous cavity. The injection is pushed inside the vitreous cavity drop by drop and then the needle is taken out. Paracentesis can be done to normalize the IOP.
