A vision screening, also called an eye test, is a brief exam that looks for potential vision problems and eye disorders. Vision screenings are often done by primary care providers as part of a child’s regular checkup. Sometimes screenings are given to children by school nurses.
Vision screening is not used to diagnose vision problems. If a problem is found on a vision screening, your or your child’s provider will refer you to an eye care specialist for diagnosis and treatment. This specialist will do a more thorough eye test. Many vision problems and disorders can be successfully treated with corrective lenses, minor surgery, or other therapies.
Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and directing treatment for a variety of diseases and conditions.
Most ultrasound examinations are done using an ultrasound device outside your body, though some involve placing a small device inside your body.
An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone).
Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.
Sound waves can travel to the inner ear through the ear canal, eardrum, and bones of the middle ear (air conduction). They can also pass through the bones around and behind the ear (bone conduction).
A Treadmill Stress Test (TMT) is a form of stress test that?s conducted while you do an exercise walking on a treadmill during the course of an Electro Cardiogram (ECG). The TMT testing compares blood circulation in your heart when you?re resting and under the influence of optimum physical pressure. A TMT is performed to ascertain the following conditions.
To identify a congenital heart problem like Coronary Artery Disease (CAD) wherein blood vessels/arteries get clogged, diseased or damaged
To determine the functioning of your heart post a heart-attack or angioplasty
To detect repressed heart conditions like shallow breathing, dizziness, chest discomfort and abrupt bodily weaknesses
To monitor the efficacy of medications applied to cure diseases such as angina and ischemia
To discern any abnormal heartbeat rate because of exertion caused by exercise
