Macular Degeneration. When the retina becomes damaged it can lead to the development of macular degeneration, also called age-related macular degeneration. When macular degeneration has developed it can cause you to be unable to see objects in the same sharp, detailed way that you used to be able to see them.
No single set of symptoms or laboratory test, such as a blood test, imaging test, genetic test, or immune function test, can independently identify MS. A doctor must use multiple tools to diagnose MS. The most important tools are the medical history, a careful and thorough neurologic exam, and magnetic resonance imaging (MRI). Other tests include visual evoked potentials (VEP) and analysis of spinal fluid taken by lumbar puncture.
If you see a specialist, he or she will ask you about your medical history and symptoms. The specialist will then examine you by feeling the area that is painful or swollen. You may have some blood tests to check your general health. If your doctor suspects you may have mesothelioma, you may have quite a few tests. This is because it can be difficult to diagnose. These tests include X-rays, a CT scan, a thoracoscopy or laparoscopy with a biopsy, and fluid drainage from around the lungs or the abdominal cavity (thoracocentesis or abdoparacentesis).
