What is interventional therapy for ophthalmic tumors?

Interventional therapy comes from interventional radiology. Under the guidance of X-ray fluoroscopy, CT localization, B-ultrasound and other medical imaging equipment, through special catheters or instruments, after the operation, we can reach the diseased area in vivo through arteries, veins, natural pipes of digestive system, biliary tract or drainage tubes to obtain information on tissues, cells, bacteria or biochemistry, and we can also take contrast photos to obtain image data, so as to achieve the purpose of diagnosing diseases, and we can also carry out various special treatments. Doctors "intervene" catheters or instruments in blood vessel branches, digestive tract and other specific parts of human body to treat diseases. Most projects of interventional therapy are carried out in blood vessels. Some diseases are treated by interventional therapy, without surgery, only a small incision less than the size of a grain of rice is needed, and a thin tube can be inserted into a blood vessel.
