Introduction:
Intravitreal injections are the most common therapeutic procedures in ophthalmology. These injections allow intraocular delivery of drugs that are highly effective for the treatment of a variety of retinal diseases. The procedure is short and simple, has an excellent local and systemic safety profile, and enables restoration and preservation of visual acuity in a large number of patients. Intravitreal injections were introduced to the routine clinical practice of ophthalmology only a little over a decade ago, but have created a therapeutic revolution due to their high efficacy, and today are an integral part of the treatment of ocular diseases. This review will cover the development of intravitreal injection treatment, describe the injected drugs, the injection technique and its possible complications, and the commonly used treatment protocols.
