An intraocular injection (i.e., an injection made directly into the eye) may sound intimidating, uncommon, and dangerous. But did you know that intraocular injections are one of the most common surgical procedures practiced today in the United States? These injections are used mostly to treat macular degeneration, a deterioration of the sensitive, central portion of the retina (the macula) that makes it the leading cause of vision loss in Americans, more than cataracts and glaucoma combined (American Macular Degeneration Foundation). In 2005, Dr. Paul T. Finger discovered that these intraocular injections can be used towards another effect: in the vision-sparing treatment of radiation retinopathy.
Radiation retinopathy, or neuropathy, occurs as a side effect of the radiation used to treat orbital tumors or melanoma. When radiated, the retina and optic nerve may be progressively damaged over time, which can lead to permanent loss of vision if left untreated. Thus, intraocular injections of ANTI-VEGF therapy, such as Avastin or Eyelea, can help to suppress this retina and optic nerve damage caused by radiation treatment.
At The New York Eye Cancer Center, we aim to provide you with the best possible information regarding intraocular injections to ease any misgivings. We are constantly monitoring our patients who have undergone treatment to watch for signs of radiation retinopathy, and if injections of ANTI-VEGF therapy are required. For these patients, we have published a video that provides all necessary information regarding their expected injections, and what they can expect before, during, and after therapy. We stress, particularly, that treating radiation retinopathy is similar to the concept of treating hypertension (high blood pressure) or diabetes; the drugs administered will diminish the damage for these long-term medical conditions.
