Eventually, the western powers instituted an airlift that lasted nearly a year and delivered much-needed supplies and relief to West Berlin. Coming just three years after the end of World War II, the blockade was the first major clash of the Cold War and foreshadowed future conflict over the city of Berlin.
Ophthalmoscopy (also called fundoscopy) is a test that allows a doctor to see inside the back of the eye (called the fundus) and other structures using a magnifying instrument (ophthalmoscope) and a light source. It is done as part of an eye exam and may be done as part of a routine physical exam.
A colonoscopy is an exam that views the inside of the colon (large intestine) and rectum, using a tool called a colonoscope. The colonoscope has a small camera attached to a flexible tube that can reach the length of the colon. Colonoscopy is done most often in a procedure room at your doctor's office. It can also be done in the outpatient department of a hospital or medical center. You will be asked to change out of your street clothes and wear a hospital gown for the procedure.
