Plaque radiotherapy is a type of radiation therapy used to treat eye tumors. A thin piece of metal (usually gold) with radioactive seeds placed on one side is sewn onto the outside wall of the eye with the seeds aimed at the tumor. It is removed at the end of treatment, which usually lasts for several days. Iodine-125 is among the isotopes used ...
The management of radiation retinopathy is similar to that for diabetic retinopathy and includes focal laser therapy to reduce macular edema or panretinal photocoagulation to treat zones of ischemia and neovascularization. Anti-vascular endothelial growth factors have been recently used for the treatment of radiation retinopathy. [4]
The most common radiation treatment is plaque brachytherapy, in which a small disc-shaped shield (plaque) encasing radioactive seeds (most often iodine-125, though ruthenium-106 and palladium-103 are also used) is attached to the outside surface of the eye, overlying the tumor. The plaque is left in place for a few days and then removed.
Aura Biosciences Inc (NASDAQ: AURA) reported data from a retrospective analysis that assessed the visual acuity after plaque radiotherapy treatment compared with prospective data in early-stage ...
Modern radiation therapy aims to reduce side effects to a minimum and to help the patient understand and deal with side effects that are unavoidable. The main side effects reported are fatigue and skin irritation, like a mild to moderate sun burn. The fatigue often sets in during the middle of a course of treatment and can last for weeks after ...
Most modern lasers will automatically center on the patient's visual axis and will pause if the eye moves out of range and then resume ablating at that point after the patient's eye is re-centered. The outer layer of the cornea, or epithelium, is a soft, rapidly regrowing layer in contact with the tear film that can completely replace itself ...
Radiation therapy is used mainly in the treatment of cancer. Radiation therapy can be used to cure, care or shrink tumors that are interfering with quality of life. Sometimes radiation therapy is used alone; other times it is used in conjunction with chemotherapy and surgery.
Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin. [1]Brachytherapy can also be used in the treatment of tumours of the brain, eye, head and neck region (lip, floor of mouth, tongue, nasopharynx and oropharynx), [10] respiratory tract (trachea and bronchi), digestive tract (oesophagus, gall ...
