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 a physical examination of the large intestine and rectum. Colonoscopies help doctors to investigate unexplained changes in a patientâs bowel habits, weight loss and abdominal pain. They are also used to screen for cancer. During the examination, a tube with a camera attached is inserted into the rectum. This camera allows the doctor to examine the patientâs colon, take biopsies and see to any polyps that need removing. A patient is usually sedated while having a colonoscopy.
