Intravitreal injections are an exceptionally effective medical treatment for several different ocular diseases. The injected medication holds many advantages over both oral and topical processes, as well as invasive surgery, including:
- Immediate localization; no need to wait for absorption through secondary media
- Lower effective dosage and frequency required
- Minimally invasive; fewer complications than surgery
Several retinal diseases are treatable with intravitreal injections, including macular degeneration, retinal vein occlusion, and diabetic retinopathy. All of these can cause blindness in their most progressed stages and thus timely treatment by intravitreal injection is crucial. In fact, macular degeneration (wet-subtype) is responsible for approximately 90% of all blindness caused by disease.
