Intraocular injections are administered for the treatment of various conditions. In many cases, they are the most effective means of treating retinal diseases, as they are highly efficient and safe. The ophthalmologist will place drops into the eye to numb the area before cleaning the eye in order to reduce the risk of infection. Once the eye has been numbed and properly prepared, the injection is administered. For some retinal diseases, repeated injections may be of benefit.
