Intravitreal Injection

An intravitreal injection is a procedure to place a medication directly into the space in the back of the eye called the vitreous cavity, which is filled with a jelly-like fluid called the vitreous humor gel. Intravitreal injections are used to administer medications to treat a variety of retinal conditions. Age-related macular degeneration (AMD), diabetic retinopathy and retinal vein occlusion are the most common conditions treated with intravitreal anti-VEGF drugs. Intravitreal steroids are used in some eyes with diabetic retinopathy, retinal vein occlusion and uveitis. The anti-VEGF drugs and steroids help to reduce fluid leakage associated with these disorders. Antibiotic, anti fungal and antiviral drugs are also used to treat patients with infections in the eye such as endophthalmitis and retinitis. In some cases an injection is used to insert a small gas bubble to aid repair of a retinal detachment. Intravitreal injections are an indispensable tool for the retina specialist to treat a variety of conditions. Their use has become much more common since the introduction of anti-VEGF medications in 2006. Intravitreal injections often need to be repeated in chronic conditions such as AMD, diabetic macular edema, and retinal vein occlusions, which require frequent office visits. Repeat injections are usually safely tolerated over several years. The need for a repeat injection is determined during the clinical examination, often with the use of diagnostic testing such as optical coherence tomography (OCT) and fluorescein angiography (FA). There are usually no restrictions following the injection apart from avoiding potential contamination of the eye on the day of the injection. However, you should contact your retina specialist if you experience signs and symptoms of complications, such as: Eye pain or discomfort Increased floaters after the first day Increased sensitivity to light Decreased vision Sometimes after an intravitreal injection, you may get the feeling that “something is in your eye”—this can be a reaction to povidone-iodine, which is used to clean the eye before the injection. Artificial tears (preferably sterile single use droppers) can be used to help ease symptoms of dryness and surface irritation. A follow-up visit with your retina specialist will be scheduled depending on the disease being treated, but is usually about 4 to 6 weeks after the injection.
