Intravitreal injections are a treatment used to treat wet macular degeneration and diabetic macular edema. They consist of locally administering an antigenic drug inside the eye. As mentioned above, the main indication is diabetic macular edema (accumulation of fluid in the macula), in which either corticoids or anti-genic are used.
Pre-and post-intravitreal injection
Prior to intravitreal injections, the Ophthalmologist will disinfect the eye and eyelids and, after the injection, antibiotic eye drops will be applied to the eye for a few days.
How long the intravitreal injection intervention lasts and possible risks
Injection is a short procedure that can be carried out in the operating room or on an outpatient basis, always requiring aseptic conditions. It is performed under topical anesthesia in the form of drops and does not usually cause discomfort, since it is administered with a very fine needle.
Although the highest risk of intravitreal injection is eye infection, if properly applied, the risk is minimal.
Effectiveness and guarantees of intravitreal injection
Intravitreal injection has very high effectiveness. In this way, the disease can be stopped in 95% of the cases and another 40% of patients improve their visual acuity. However, it should be noted that several injections are necessary to achieve evolution and improvement.
