This video demonstrates the technique of intravitreal triamcinolone acetonide 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. Ocular surface is thoroughly washed with saline and 5% povidone iodine is applied. Intravitreal anti-VEGF injection is taken in an one mL tuberculin syringe. In phakic case, it is introduced through pars plana area 4 mm away from the limbus. Tip of the 30G needle should be well visualized with beveled tip up directed towards the centre of the vitreous cavity. The injection is pushed inside the vitreous cavity drop- by-drop then then the needle is taken out. Paracentesis can be done to normalize the IOP.
